Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring systems (CMS) - Part 13: Optical 3D CMS (ISO 10360-13:2021)

This part of ISO 10360 specifies the acceptance tests for verifying the performance of an optical CMS
(coordinate measuring system) when measuring lengths as stated by the manufacturer. It also
specifies the reverification tests that enable the user to periodically reverify the performance of the
optical 3D CMS. An optical 3D CMS that this standard intends to specify is a contactless area
measuring sensor delivering 3D surface data in several individual single views by an optical measuring
principle and transforming it into a common coordinate system. Typical optical measuring principles are
pattern projection, fringe projection, and project-and-sweep a scanned line, or similar, delivering single
views without assistance of external information related to position and orientation between CMS and
objects to be scanned. Typical registration principle is based on a best fitting of commonly captured
position information across at least two different single views either or both by using reference targets
or surface features of objects to be scanned.

Introduction

This document is a geometrical product specification (GPS) standard and is to be regarded as a general

GPS standard (see ISO 14638). It influences chain link F of the chain of standards on size, distance,

form, orientation, location and run-out in the general GPS matrix (see Annex H).

The ISO GPS matrix model given in ISO 14638 gives an overview of the ISO GPS system, of which this

document is a part. The fundamental rules of ISO GPS given in ISO 8015 apply to this document and

the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this

document, unless otherwise indicated.
This document has two technical objectives:

1) to test the error of indication when measuring a calibrated test length across the global measuring

volume of the CMS;
2) to test the errors of indication within a locally intended measuring volume.
These two objectives correspond to:

a) the test performed for a probing system and a moving carrier of the probing system in combination

as described in ISO 10360-2, ISO 10360-7, ISO 10360-8, ISO 10360-10, ISO 10360-11 and

ISO 10360-12;

b) the test performed dominantly for the probing system as described in ISO 10360-5, ISO 10360-7,

ISO 10360-8, ISO 10360-9, ISO 10360-10, ISO 10360-11 and ISO 10360-12.

The benefits of these tests are that the measured result has a direct traceability to the unit of length,

the metre, and that it gives information on how the coordinate measuring machine (CMM) or the

coordinate measuring system (CMS) performs in similar length measurements.

An optical 3D CMS as specified by this document is a contactless area measuring sensor delivering

3D data in several individual single views by an optical measuring principle and transforming it into

a common coordinate system. Typical optical measuring principles are pattern projection, fringe

projection and projecting-and-sweeping a scanned line, or similar, delivering single views without

assistance of external information related to position and orientation of the objects to be scanned

relative to the CMS. Typical registration principles are based on a best fitting of commonly captured

position information across at least two different single views by using either or both reference features

attached or surface features of the objects to be scanned.
This document is not intended to apply to other types of CMSs, for example:
— tactile CMMs (Cartesian metrological moving carrier), see ISO 10360-2;
— imaging CMMs (Cartesian metrological moving carrier), see ISO 10360-7;

— CMMs equipped with optical distance sensors (Cartesian metrological moving carrier), see

ISO 10360-8;
— laser trackers, see ISO 10360-10;
— X-ray CTs, see ISO 10360-11;
— articulated arm CMMs, see ISO 10360-12;

— measuring instruments intended to measure surface characteristics, see the ISO 25178 series;

— optical microscopes;
— hand-held laser-line type scanners.

Parties can apply this document to the above or other types of CMSs by mutual agreement.

This document specifies:

— performance requirements that can be assigned by the manufacturer or the user of the CMS;

— the manner of execution of the acceptance and reverification tests to demonstrate the stated

requirements;
— rules for verifying conformance;
— applications for which the acceptance and reverification tests can be used.

NOTE 1 Annex E describes possible limitations with regard to less cooperative surface characteristics,

such as colour, glossiness and roughness, and provides a suggested test that can give CMS users an idea of how

representative the maximum permissible error would be when measuring their specific industrial part.

NOTE 2 The optical 3D CMS can be moved and positioned by a manually or automated moving unit. The

position, orientation or both can be used as additional information for the registration.

NOTE 3 The acceptance and reverification tests are designed to mimic real but simple measurements

occurring in practice, subject to the rated operating conditions and the testing procedures. The user is advised

to consider the influence of additional or omitted conditions, procedural steps or both when applying the test

results according to this document to predict the performance of an actual CMS.

model, see Annex H.

This document specifies the acceptance tests for verifying the performance of an optical 3D coordinate

measuring system (CMS) when measuring lengths as stated by the manufacturer. It also specifies the

reverification tests that enable the user to periodically reverify the performance of the optical 3D CMS.

This document is applicable to verification of the measuring performance of CMSs if the surface

characteristics (e.g. glossiness, colour) of the object to be scanned are restricted and within a

cooperative range.

This document does not apply to other types of CMSs, including those covered by the other parts of the

sensor measurement volume

volume of measurement of the sensor realized without movement of the sensor relative to the workpiece

fulfilling the specifications stated by the manufacturer

Note 1 to entry: Dimensional indication of sensor measurement volume stated by the manufacturer can

significantly differ from that which the sensor shows.
3.3
registration

transformation of coordinate systems that brings single-view coordinates into a unified coordinate

system

Note 1 to entry: A transformation is realized for example by a rigid transformation, consisting of either

translation, rotation or both.

Note 2 to entry: Each single view holds its own coordinate system and requires a transformation to the unified

coordinate system.

Note 3 to entry: The registration is invertible. The inverse registration can be performed by applying the inverse

transformation.

Note 4 to entry: In practice, the transformation parameters are derived first, then the transformations occur

either immediately or at a later stage.
Note 5 to entry: A registration can require a person to operate the CMS.
3.4
fusion

operation that merges two or more sets of measured coordinates into a unified set of measured

coordinates

Note 1 to entry: Fusions are performed to improve the measurement, e.g. to reduce the dispersion and the

mismatch of single views.
Note 2 to entry: Fusions are typically irreversible (not invertible).

Note 3 to entry: A fusion can include any number of elementary operations in combination or in sequence, such as

coordinate transformation, averaging, outlier rejection, decimation, convolution and filtration.

Note 4 to entry: The fusion can occur either immediately or at a later stage.
3.5
concatenated measurement volume

volume of measurement of the CMS obtained by movement of the sensor relative to the workpiece and

the registration fulfilling the specifications stated by the manufacturer

Note 1 to entry: The concatenated measurement volume can be determined by design of a measuring cabin

typically having a cuboid boundary or a three-dimensional size of the intended workpiece.

Note 2 to entry: A concatenated measurement volume can have either a significantly larger volume than the

sensor measurement volume or a similar volume to the sensor measurement volume.
3.6
single-view measurement

measurement of spatial coordinates done with an optical sensor without movement relative to the

workpiece

Note 1 to entry: Single-view measurement is performed with no movement of the carrier, registration or fusion.

Note 2 to entry: Single-view measurement can include repeated measurements, for example multiple exposures,

provided that no movement of the optical sensor relative to the workpiece occurs from the first exposure to the

last.

Introduction

This document is a geometrical product specification (GPS) standard and is to be regarded as a general

GPS standard (see ISO/TR 14638). It influences link 5 of the chains of standards on size, distance, radius,

angle, form, orientation, location, run-out and datums. For more detailed information of the relation of

this document to other standards and the GPS matrix model see Annex G.

The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this

document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and

the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this

document, unless otherwise indicated.
This document has two technical objectives:

1. to test the error of indication when measuring a calibrated test length across the global measuring

volume of the CMS, and
2. to test the errors of indication within a locally intended measuring volume.
These two correspond to:

a) the test performed for a probing system and a moving carrier of the probing system in combination

as described in ISO 10360-2, -7, -8, -10, and 11, and

b) the test performed dominantly for the probing system as described in ISO 10360-5, -7, -8, -9, -10,

and -11.

The benefits of these tests are that the measured result has a direct traceability to the unit of length,

the metre, and that it gives information on how the CMM (Coordinate Measuring Machine) or the CMS

(Coordinate Measuring System) will perform on similar length measurements.

In close reliance on ISO 10360-2 and ISO 10360-5 for CMS equipped with contact probing systems,

as well as on ISO 10360-8 for CMS with optical distance sensors, this part of ISO 10360 specifies the

acceptance and reverification tests for verifying the performance of optical 3D coordinate measuring

systems. The testing methodology of these three parts of ISO 10360 is designed to be identical wherever

technically possible.

DRAFT INTERNATIONAL STANDARD ISO/DIS 10360-13:2020(E)
Geometrical product specifications (GPS) — Acceptance
and reverification tests for coordinate measuring
systems (CMS) —
Part 13:
Optical 3D CMS
1 Scope

This document specifies the acceptance tests for verifying the performance of an optical CMS (Coordinate

Measuring System) when measuring lengths as stated by the manufacturer. It also specifies the

reverification tests that enable the user to periodically reverify the performance of the optical 3D CMS.

An optical 3D CMS that this standard intends to specify is a contactless area measuring sensor delivering

3D data in several individual single views by an optical measuring principle and transforming it into

a common coordinate system. Typical optical measuring principles are pattern projection, fringe

projection, and project-and-sweep a scanned line, or similar, delivering single views without assistance

of external information related to position and orientation of the objects to be scanned relative to

the CMS. Typical registration principles are based on a best fitting of commonly captured position

information across at least two different single views, either or both by using reference targets or

surface features of the objects to be scanned.

This standard applies to verification of the measuring performance of CMSs in case the surface

characteristics (e.g. glossiness, colour) of the object to be scanned are restricted and within a

cooperative range.

This standard does not explicitly apply to other types of CMSs, including those standardized by the

other parts of ISO 10360 or other standards. In the list below, a metrological moving carrier is a mover

equipped with scales measuring the position and/or orientation of the probing system, to be used as

essential information for the determination of the measurement result.
• tactile CMMs (Cartesian metrological moving carrier): ISO 10360-2,
• imaging CMMs (Cartesian metrological moving carrier): ISO 10360-7,

• CMMs equipped with optical distance sensors (Cartesian metrological moving carrier): ISO 10360-8,

• laser trackers: ISO 10360-10,
• X-ray CTs: ISO 10360-11,

• articulated arm CMMs (anthropomorphic metrological moving carrier): ISO 10360-12,

• measuring instruments intended to measure surface characteristics: ISO 25178,
• optical microscopes,
• hand-held laser line(s) scanners.

Parties may apply this part of 10360 to the above or other type CMSs by mutual agreement.

This part of ISO 10360 specifies:

— performance requirements that can be assigned by the manufacturer or the user of the CMS,

— the manner of execution of the acceptance and reverification tests to demonstrate the stated

requirements,
— rules for verifying conformance, and
— applications for which the acceptance and reverification tests can be used.

Note 1 Annex E describes possible limitations with regard to less cooperative surface characteristics,

e.g. colour, glossiness and roughness, and provides a suggested test that may give CMS users an idea of how

representative the maximum permissible error would be when measuring their specific industrial part.

Note 2 The optical 3D CMS can be moved and positioned by a manually or automated moving unit. The

position and/or orientation can be used as additional information for the registration.

Note 3 The acceptance and reverification tests are designed to mimic real but simple measurements

occurring in practice, subject to the rated operating conditions and the testing procedures. The user is advised to

consider the influence of additional or omitted conditions and/or procedural steps when applying the test results

according to this standard to predict the performance of an actual CMS.

3.2
sensor measurement volume

volume in which the sensor in still motion can measure, fulfilling the specifications provided by the

manufacturer according to this standard
3.3
registration

transformation(s) of coordinate systems that brings single-view coordinates into a unified

coordinate system

Note 1 to entry: to entry: A transformation is realized e.g. by linear homogeneous transformation or rigid

rototranslation in the other word, consisting either or both of rigid body translation and/or rigid body rotation.

Note 2 to entry: to entry: Each single-view holds its own coordinate system and requires a transformation to the

unified coordinate system.

Note 3 to entry: to entry: The registration is invertible. The inverse registration is performed by applying the

inverse transformation.

Note 4 to entry: to entry: In a registration, the transformation parameters are derived first, and then the

transformations occur. The latter may occur either immediately or significantly after the former.

Note 5 to entry: to entry: A registration may or may not require a person to operate the CMS.

3.4
fusion

operation that merges two or more sets of measured coordinates into a unified set of measured

coordinates

Note 1 to entry: to entry: Fusions are performed to improve the measurement, e.g. to reduce the dispersion and

the mismatch of single views.
Note 2 to entry: to entry: Fusion are typically irreversible (not invertible).

Note 3 to entry: to entry: A fusion may include any number of elementary operations in combination and/or in

sequence, such as coordinate transformation, averaging, outlier rejection, decimation, convolution, filtration.

Note 4 to entry: to entry: The fusion may occur either immediately or significantly after the registration.

3.5
concatenated measurement volume

volume of measurement of the CMS obtained by movement of the sensor and registration fulfilling the

specifications provided by the manufacturer according to this standard.

As a default, the longest length fully inside the concatenated measurement volume shall be no shorter

than twice the longest length fully inside the sensor measurement volume.

Note 1 to entry: The concatenated measurement volume can be given by design of a measuring cabin or a

dimension of a typical workpiece to be measured.
3.6
single-view measurement

measurement of spatial coordinates done with an optical sensor in the still motion relative to the

workpiece

Note 1 to entry: Single-view measurement is performed with no movement of the carrier, registration nor fusion.

when measuring a sphere, and the qualifier “O3D” indicates that it is associated with an optical 3D CMS. The

qualifier “i” identifies the percentile of probing points selected for the evaluation: either “D95%” denoting 95 %

of the population or “All” denoting the whole population, i.e. 100 %. The qualifier “j” identifies the measuring

conditions of the CMS: “SMV.SV” denotes single-view measurement while “SMV.MV” multiple-view measurement;

the measurement is performed within the sensor measurement volume (“SMV”) in either case. Possible examples

of such symbol are P or P .

present in the measurement data may be eliminated by this operation.

Note 3 to entry: It could be beneficial to evaluate probing errors from point cloud both from “95%” population and

“All” population. A difference in these two test results may reveal influences of smoothing filters or equivalent

functions potentially pre-installed as an integral part of the CMS or the associated software, which is not always

transparently visible for users of the CMS.
