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.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 63033-3:2019. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

INTRODUCTION
This document specifies measurement methods for the drive monitoring surround view system
specified in IEC TS 63033-1:2017, which also specifies the model for generating the
surrounding visual image of a drive monitoring 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
The system model of the drive monitoring system is described in Figure 1. A drive monitoring
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 fully
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 TS 63033-1:20172022,
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 comply with 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. Some examples of views representing FOVs of Class I to VI is 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 30 fps 15 fps. While manoeuvring at low speed, the frame
rate can drop (e.g. owing to image processing) but shall be never be below 15 fps. The frame
rate shall be measured as specified in ISO 16505:2019, 7.9.1.

– 10 – IEC 63033-3:2022 RLV © 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.
Annex A
(informative)
Field of view (FOV)
Figure A.1 to Figure A.8 provide some examples of views representing FOVs of class I to VI, a
larger FOV on the passenger side, and also some example of views as specified within section
5.4.1 of UN Regulation No. 125, using an image generated by more than two cameras
comprising a drive monitoring surround view system. However, the generated example views
provided in this document do not necessarily comply with uniform provisions as described, for
example, in the UN Regulation No. 46 or UN Regulation No. 125. For more details on what can
be displayed and what cannot be displayed, it is strongly recommended to check the applicable
existing regulations.
