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.

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.

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.

– 8 – IEC 63033-2:2018 © IEC 2018
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 included
in 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 data
at 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).

IEC 63033-2:2018 © IEC 2018 – 9 –
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 in
the 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.

5 Viewer
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.
