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

INTRODUCTION
This document specifies recording methods of the drive monitoring system that is specified in
IEC TS 63033-1, which also specifies the model for generating the surrounding visual image
of the drive monitoring 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, offering the most appropriate views according to the driving situation.
IEC 63033-2 specifies recording methods of the drive monitoring system in order to view the
recorded video file with "free eye point" technology.---------------------- Page: 7 ----------------------

4 System model
4.1 General
IEC 63033-2 specifies recording methods of the drive monitoring system. Specifically, the
recording from a vehicle-mounted camera as obtained by the drive monitoring system, and
also a model for the replay of the recorded video. The purpose of the replay of the recorded
video can be considered in various ways, such as verification at the occurrence of an accident,
as legal proof, for reviewing driving behaviour and use at educational sites.There are two types of recorded videos: recording of each camera image (referred to as
"recording 1"), and recording of the composite image (referred to as "recording 2"). For replay
of the recorded videos, the related metadata (refer to 4.2.2.3 and 4.2.3.3) is simultaneously
saved in recording 1 and recording 2. These recorded files are transferred by the portable
recording medium or via a network, where they can be later replayed by the user. The user
---------------------- Page: 8 ----------------------IEC 63033-2:2018 © IEC 2018 – 7 –
can also recreate the composite image by using the stored metadata in the free eye point in
the viewer (refer to Clause 5). It is also possible to provide the distribution service with the
recorded file by using storage on the network.Figure 1 – Displaying and Recording system model of drive monitoring system
4.2 Video recording
4.2.1 General
There are two types of recording files provided by the driver monitor system and as shown
Figure 1: recording 1 and recording 2.4.2.2 Recording 1
4.2.2.1 General
Recording 1 consists of both the raw (before composite) video data as obtained by each
camera, and related metadata (refer to 4.2.2.3) at the same time. Using both, the video data
and the metadata, enables the user to recreate a new composite image. The user can change
the view point freely while viewing the composite image. In addition, they can also see a
vehicle’s surroundings instantly in a single composite image.4.2.2.2 Video data
The raw video data obtained from the vehicle-mounted cameras is recorded. A raw video data
example is shown in Figure 2.Since the recording is pre-composition, there is no distortion and the image cut-off is as
directly input from each vehicle-mounted camera. This method allows for the full image to be
transferred, thus, keeping as much of the original image information.Figure 2 – Raw video data example of recording 1, the image before composition

4.2.2.3 Metadata for recording 1
The metadata listed in Table 1 and Table 2 shall be saved together with the video data. Some
metadata will be included in the SIM source packet.Table 1 – Metadata for recording 1
Metadata Explanation Mandatory
Time stamp It is necessary to identify the exact time when a certain event occurred. The
time information is generally extracted from GNSS. If GNSS is not includedin the system, the time information can be extracted from another system
equivalent to GNSS.
GNSS It is necessary to identify details about the location and the exact time when ✔
a certain event occurred.ID data It is necessary to specify which car the recorded file came from. ✔
Orientation It is necessary to identify details about orientation when a certain event
occurred.Table 2 – Metadata for dependent part of video data 1
Metadata Explanation Mandatory
Optical axis shift The optical axis shift adjusts the central coordinates and the captured
data image’s width and height.For details, please see IEC TS 63033-1.
Lens distortion data Distortion data of lens used for each camera.
For details, please see IEC TS 63033-1.
Camera position and Camera position information consisting of mounted camera position (X, Y, Z)
direction dataat optics' centre (mm) and camera angle (tilt angle ψ, rot angle φ, pan
angle θ) at optical axis direction (in °).
For details, see IEC TS 63033-1.
View point position The same view point position data as registered to make the existing Preferable to
and direction data composite image. It contains the virtual view point position (X, Y, Z), angle be saved
and virtual 3D projection surface.3D car model data The same 3D car model data and size as registered to make the existing Preferable to
and size composite image. It contains 3D model data, transparency and drawing car be saved
model size (left, front, right, bottom, tail, top) described in mm.4.2.3 Recording 2
4.2.3.1 General
Recording 2 records both the composite image video data and the related metadata (refer to
4.2.3.3) at the same time. A composite image video data example is shown in Figure 3.
Users cannot change the view point while viewing the composite image. However, the user
can instantly view the vehicle’s surroundings through a specific pre-set composite image
regardless of the viewer used (see Clause 5 for details).---------------------- Page: 10 ----------------------

Figure 3 – The composite video data example of recording 2
4.2.3.2 Video data
The composite video data obtained from vehicle-mounted cameras is recorded.
Compared to the case of recording the raw video data of all cameras, it can reduce the data
size and memory required since only the composite result is recorded. On the other hand, the
image information from each camera that has not been used in the composite image will be
lost.4.2.3.3 Metadata for recording 2
The metadata listed in Table 3 shall be saved together with the video data. Some metadata
will be included in the SIM source packet.Table 3 – Metadata for recording 2
Metadata Explanation Mandatory
Time stamp It is necessary to identify the exact time when a certain event occurred. The
time information is generally extracted from GNSS. If GNSS is not included inthe system, the time information can be extracted from another system
equivalent to the GNSS.
GNSS It is necessary to identify details about the location and the exact time when a
certain event occurred.ID data It is necessary to specify which car the recorded file came from.
Orientation It is necessary to identify details about orientation when a certain event
occurred.Since users cannot create a composite image in recording 2, only the metadata given in Table
4 is required.Table 4 – Metadata for dependent part of video data 2
Metadata Explanation Mandatory
View point position The same view point position data as registered to make the existing Preferable to
and direction data composite image. It contains virtual view point position (X, Y, Z), angle and the be saved
virtual 3D projection surface.---------------------- Page: 11 ----------------------

5.1 General
Figure 4 – Viewer example
The term "viewer" is referred to as the video player necessary to view the recorded file and
can be classified into two types as shown in Figure 4. These are further referred to as the
"general viewer" and "enhanced viewer" depending on whether or not the viewer has a free
view point function.5.2 General viewer
The general viewer plays the recorded video data just as it is, and sometimes crop and zoom
functions are enabled. The metadata regarding the time stamp, GNSS and orientation shall be
synchronous with the video data and displayed in the viewer.5.3 Enhanced viewer
In addition to the general viewer's basic function, the enhanced viewer enables users to view
the video data with the free view point function. In order to generate a composite image with
"free eye point", the video data and the metadata recorded in recording 1 is necessary.
