FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC 63033-3 has been prepared by technical area 17: Multimedia systems and equipment for

vehicles, of IEC technical committee 100: Audio, video and multimedia systems and equipment.

It is an International Standard.

This second edition cancels and replaces the first edition published in 2019. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) updates to the text and the title to reflect the change of the scope of the IEC 63033 series.

the above table.
The language used for the development of this International Standard is English.

A list of all parts in the IEC 63033 series, published under the general title Multimedia systems

and equipment for vehicles – Surround view system, can be found on the IEC website.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are

described in greater detail at www.iec.ch/standardsdev/publications.

INTRODUCTION

This document specifies measurement methods for the surround view system specified in

IEC 63033-1, which also specifies the model for generating the surrounding visual image of a

surround view system. The system allows drivers to monitor the car’s perimeter in real time by

using “free eye point” technology, which allows drivers to dynamically change the viewing

perspective to obtain the most appropriate views according to the driving situation.

3.1 Abbreviated terms
FOV field of view
4 System model

A surround view system shall generate multiple camera composite images and/or single camera

images, using cameras that are mounted on the outside the car. The system model of the

surround view system is described in Figure 1. The views to be generated by this system shall

capture the fields of view specified in Clause 7. This system shall generate multiple views

according to the fields of view to be secured. For measurement methods, the system shall refer

to ISO 16505 and UN Regulation No. 46. However, the system itself does not need to comply

with ISO 16505 and UN Regulation No. 46.

5 Camera image quality
5.1 Camera resolution
The resolution of the camera shall be 300 000 pixels or more.
5.2 Camera image quality

The camera's image quality shall comply with ISO 16505:2019, 6.7, and shall be measured as

specified in ISO 16505:2019, 7.8. The monitor's image quality shall comply with

ISO 16505:2019, 6.7, and shall be measured as specified in ISO 16505:2019, 7.8, as well. For

the measurement of the camera's image quality, a monitor satisfying the requirements in the

previous sentence shall be used.
6 Camera calibration
6.1 General

The calibration of the camera shall be performed as specified in IEC 63033-1:2022, Annex C.

6.2 Verification

Draw an orthogonal frame at a distance of 1,5 m from the outline of the vehicle; this frame is to

be captured within the camera's image. This frame is shown in Figure 2 and can be seen on the

captured camera image. The guidance lines shown in Figure 3 representing the frame 1,5 m

around the car's body that is later drawn on the composite video shall match up within a

tolerance of 10 cm.

7 Field of view

The field of view of the system is the visible area displayed by composite images (i.e. from the

multiple cameras composing the system) or the image captured by any single camera that is

then converted and displayed. If the target of the application of this system is to replace an

existing type approval that is required for vehicular equipment, it shall follow the respective

regulation. For example, the FOV shall capture the respective FOV defined in UN Regulations

No. 46 and No. 125 (Class I to VI) if the system is intended to be used in such an application.

The details are described in Annex A. The compulsory or optional FOV shall follow the

requirement specified in the table under paragraph 15.2.1.1.1. in UN Regulation No. 46.

8 Time behaviour
8.1 Start-up time

The manufacturer of the camera ECU shall provide information of the start-up time of the system.

The start-up time means the time from powering on the ignition to the initial composite view

being displayed on the monitor. The start-up time shall be 7 s or less. The start-up time shall

be measured as specified in ISO 16505:2019, 7.3.
8.2 Frame rate

The manufacturer of the camera ECU shall provide information on the frame rate of the system.

The frame rate shall be more than 15 fps. The frame rate shall be measured as specified in

ISO 16505:2019, 7.9.1.
---------------------- Page: 11 ----------------------
– 10 – IEC 63033-3:2022 © IEC 2022
8.3 Latency

The camera's ECU should have a sufficiently short latency to render the image to display at

nearly the same time as the camera image is captured. The latency is the time difference from

when a light is captured by the camera until the time it becomes visible to the display. The

latency shall be lower than 200 ms and shall be measured as specified in ISO 16505:2019,

7.9.3.
