INTRODUCTION
The purpose of this document is to specify the model for generating the surrounding visual
image of the surround view system, which provides drivers with an image of the car's
surroundings. The surround view system is characterised by audio-visual monitoring and
recording, which is part of the car's multimedia equipment.
When manoeuvring, the driver relies on the images provided by the rear-view monitor for
parking assistance, the blind spot monitor for displaying views of the blind spots at intersections
with poor visibility, and the bird's-eye view monitor. But each surround view system provides a
different viewpoint to the driver. It's a heavy burden for a car driver to switch between these
systems and quickly recognize the multiple fields of view. And the fields of view are limited to
these camera systems, and they cannot freely change the viewpoint depending on the driving
situation. Thus, the usage range of these systems is limited to such manoeuvres as parking
assistance. Furthermore, on commercial vehicles such as trucks and buses, and special
vehicles such as construction machinery and agricultural machinery, the usage range of these
systems is even more limited. Nobody can assist drivers of large vehicles in ensuring the car's
correct position.
With a surround view system, it is possible to quickly ensure the car's proper positioning in
various driving situations. And not only for passenger cars, but good positioning can also be
quickly ensured for commercial vehicles and special vehicles.
This document specifies the model for generating the surrounding visual image of the surround
view system. IEC 63033-2 specifies the information sets that are provided by the surround view
system, and recording methods for that information and visual images. IEC 63033-3 specifies
the measurement methods of surrounding visual images for the surround view system.

4 System model
4.1 General
The system model of the surround view system is described in Figure 1. Cameras, which are
mounted on the outside of the car, capture the visual image of the area surrounding the car and
these visual data are projected onto a 3D projection surface. The visual image can then be
displayed as a composite image. The images can be rendered from various viewpoints with the
parameters for capture. The number of cameras required on vehicles other than automobiles
can be more than four depending on the size and shape of the car. This model defines a system
with four cameras for general application. The number of cameras actually used for each
composite image changes depending on the viewpoint. The mounting positions and angles for
the four cameras should be calibrated in accordance with the data described in 4.2 and 4.3.

– 8 – IEC 63033-1:2022 © IEC 2022
See Annex D for information about display attributes and Annex E for information about the
reactivity of the system.
Figure 1 – System model for surround view system
4.2 Number of cameras and camera field of view
The horizontal angle of view of the camera is described in Figure 2. Overlapping areas and
blind spots on the horizontal field of view change depending on the number of cameras and the
horizontal angle of view of the camera. Overlapping areas should be wide for getting better
composite views. The number of cameras and the horizontal angle of view of the camera shall
be determined to ensure that there are no blind spots.
The vertical angle of view and the tilt angle ψ of the front camera and the vertical angle of
Front
view and the tilt angle ψ of the rear camera are described in Figure 3. The blind spot of the
Rear
vertical field of view changes depending on the vertical angle of view of the camera and the tilt
angle ψ. The vertical angle of view of the camera and the tilt angle ψ shall be chosen to ensure
that no blind spots are generated. The details are described in Annex A.

Figure 2 – Horizontal angle of view of the camera

Figure 3 – Vertical angles of view at the camera
4.3 Method for projecting visual image to 3D projection surface
Following the right-handed coordinate system, the length of the car is the Y axis, the width
car
direction of the car is X axis, and the direction of the height of the car is the Z axis. The
car car
projection surface of the camera video image is Z = 0, the road surface. The 3D projection
V
surface that shall be used is shown in Figure 4. Projecting to a 3D projection surface is
described in Figure 5. The 3D projection surface should cover the 3D surface as the polygon
model is similar to a polyhedron. The coordinate P of the one point of the 3D projection surface
V
is converted to the coordinate P according to the camera's coordinate system based on the
C
origin of the optics of the car's cameras. This coordinate conversion is defined as:
PM ×P
C VC→ V
=
– 10 – IEC 63033-1:2022 © IEC 2022
M is the coordinate conversion matrix to the car's coordinate system, which is determined
V→C
by the camera's mounting position and the angle. The incident vector V when the car's camera
i
photographs the subject at position P is defined as:
C
P
C
V=−
i
P
C
The coordinates of the car's camera image record the subject of incident vector V calculated
i
by the internal parameter of the car's camera. Projecting the car's cameras to a 3D projection
surface is realized by arranging the pixels of four cameras with the relations mentioned above.

Figure 4 – 3D projection surface

Figure 5 – Projecting to 3D projection surface
4.4 Visualizing the projection image at free eye point
The polygon model constituting the 3D projection surface can be visualized from any virtual eye
point. Visualizing the polygon model uses 3D computer graphics technology. The texture image
is the car's camera image updated at the system's video rate. The wrap-around view image is
composed by performing the polygon rendering and the texture coordinate is the car's camera
image coordinate that corresponds to the top of the polygon.
4.5 Free eye point capability
The parameters of the eye point, direction and field of view of the virtual camera are freely
changed during polygon rendering. The eye point can be changed by changing the parameters
of the virtual cameras, the car's surroundings and the driving situation for the same 3D
projection surface. The animated image tied between individual eye points is smoothly adjusted
by changing these parameters continually.
5 Camera configuration
5.1 Camera
The lens of the camera should be isotropic and have a rotary symmetric distortion characteristic
in an optical axis. The details are described in Annex B.
5.2 Lens distortion data
5.2.1 General
Lens distortion data should be used during calibration. Lens distortion data should be arranged
according to the coordinate data of the height of the real image corresponding to the incidence
angle value in ascending order. The type of lens distortion data is either of rotationally
symmetric lenses or of non-rotationally symmetric lenses.

– 12 – IEC 63033-1:2022 © IEC 2022
5.2.2 Distortion data of rotationally symmetric lens
Distortion data of rotationally symmetric lenses is described in Figure 6. It is composed of the
angles of incidence a and a between the optical axis's centre and their distances d and d
1 2 1 2
from the centre. The distortion data format of a rotationally symmetric lens is described in
Figure 7.
Figure 6 – Distortion data of a rotationally symmetric lens

Figure 7 – Distortion data format of rotationally symmetric lens
5.2.3 Distortion data of non-rotationally symmetric lens
Distortion data of non-rotationally symmetric lenses is described in Figure 8. It is composed of
an angle of incidence (pan angle and tilt angle) and the location (x,y) on the imaging element.
The distortion data format of a non-rotationally symmetric lens is described in Figure 9.

Figure 8 – Distortion data of a non-rotationally symmetric lens

Figure 9 – Distortion data format of a non-rotationally symmetric lens
5.3 Optical axis shift data
Optical axis shift data should be used at calibration. Optical axis shift includes optical axis shift
of camera, shift by AD or DA conversion, and shift from the ideal captured image. The optical
axis shift adjusts the shift from the central coordinates and the captured image's width and
height as an input. Optical shift data that should be matched on the texture coordinate is
described in Figure 10. The format of optical shift data is described in Figure 11.

6 Rendering
6.1 General
The composite view data should be designed by the camera ECU manufacturer beforehand. In
real time, the composite view is to be rendered using the camera parameter generated in 5.2
and 5.3 based on the composite view data designed beforehand. For every composite view
data, the following data and parameters should be set:
– 3D projection surface data,
– capture specification data,
– conversion of eye point parameter,
– virtual 3D image car model data,
– guide lines and bitmap data,
– layout data and layer setting data.
6.2 Composite view data
6.2.1 3D projection surface data
3D projection surface examples are described in Figure 12. They should be designed depending
on the car's size, the car's shape and the virtual eye point in every composite view data.

Figure 12 – 3D projection surface data
6.2.2 Capture size
Capture size indicates an effective pixel size of each camera actually used. The capture
specification data format is described in Figure 13. Capture size should be determined
depending on the camera's resolution.

Figure 13 – Capture specification data format
6.2.3 Conversion of eye point parameter
The eye point should be fixed in every composite view depending on camera angle, position
and scaling. The position of the point of view, the direction of view, and the scope of the field
of view are interpolated before and after changing the point of view. Therefore, the driver can
instantly recognize from what position the car is being viewed, and quickly ensure correct
positioning on the road. The camera angle in the conversion of the eye point is described in
Figure 14. Camera position/scaling in the conversion of the eye point is described in Figure 15.

Figure 14 – Camera angle in conversion of eye point

Figure 15 – Camera position/scaling in conversion of eye point

– 16 – IEC 63033-1:2022 © IEC 2022
6.2.4 Virtual 3D image car model data
Virtual 3D image car model data should be designed with real dimensions based on the
circumscription quadrangle of the camera's mounting position defined in 4.4. The transmittance
of virtual 3D image car model data should be set in every composite view data. Virtual 3D image
car model at original dimensions is shown in Figure 16. Virtual 3D image car model at real
dimensions is shown in Figure 17.

Figure 16 – Virtual 3D image car model at original dimensions

Figure 17 – Virtual 3D image car model at real dimensions
6.2.5 Guide line and bitmap data
An example of a guide line for highlighting the position of the car and an example of a bitmap
for highlighting the virtual eye point shown in Figure 18 should be added for GUI improvement.

Figure 18 – Guide line and bitmap data
6.2.6 Layout data and layer setting data
Layout data and layer setting data should be designed in every composite view data. Layout
data should be defined by the camera image coordinate system described in Figure 19, the
screen coordinate system described in Figure 20, and the object coordinate system described
in Figure 21. The camera image coordinate system deals with an actual camera image. Its size
is the input size of an actual camera image. The screen coordinate system deals with an object
on an actual screen and can lay out two or more objects in the screen. The object coordinate
system deals with separate objects respectively in the coordinate system. The relation of layout
data and layer setting data is described in Figure 22.

Annex A
(informative)
Camera mounting to the car
A.1 Camera mounting position
Each camera should be mounted on the outside edge of the car to avoid having the body of car
shrouding the camera views. The front camera and the rear camera should be mounted on the
middle of the left to right axis, and the left camera and the right camera should be mounted on
the middle of the front to rear axis. The four camera mounting positions are depicted in
Figure A.1.
Figure A.1 – Camera mounting position
A.2 Camera mounting height
Each camera should be mounted at a height of more than 60 % of the height of the car's body.
The four cameras should be mounted at the same height to prevent large gaps in the composite
view at the border area between the cameras. Increasing the height gap between the cameras
also increases the parallax between the cameras. The camera mounting height should be
adjusted to decrease the parallax between the cameras as much as possible. The mounting
height of the four cameras is shown in Figure A.2.

Figure A.2 – Camera mounting height
A.3 Camera mounting angle
The angle of each camera should be adjusted so that the 360° at the road surface are
photographed by the four cameras. The angle of each camera should be fixed in the calibration
process (see Annex C). The mounting angles of the four cameras are shown in Figure A.3.

Annex B
(informative)
Camera field of view
The horizontal view angle of the camera should be more than 180°. The vertical view angle of
the camera should be more than 130°.

Annex C
(informative)
Camera calibration
Camera calibration is shown in Figure C.1. The mounting positions and angles for the four
cameras should be calculated to use lens distortion data and optical axis shift data of the car's
coordinate system. In real use cases, mounting positions and angles for the four cameras
should be adjusted for making the composite views better.
– Mounting position: x, y, z at optical centre (mm)
– Mounting angle: tilt angle ψ, rot angle φ, pan angle θ at optical axis direction (°)

Annex D
(informative)
Display
D.1 Display specification data
Display specification data should be fixed in every composite view. Display specification data
should be determined depending on the camera's resolution.
D.2 Composite view change mode
Composite view change mode should be fixed beforehand. The trigger of the composite view
change should be designed as the following:
– user operation,
– CAN information.

Annex E
(informative)
Time behaviour
E.1 Start-up time
The manufacturer of the camera ECU should provide information of the start-up time of the
system. The start-up time means the time from power-on ignition to the composite view being
displayed on the monitor. The start-up time should be within 10 s.
E.2 Frame rate
The manufacturer of the camera ECU should provide information of the frame rate of the system.
The frame rate should be more than 30 frames/s.
E.3 Latency
The camera ECU should have a sufficiently short latency in order to render the image nearly at
the same time as the camera image is captured. The latency should be lower than 200 ms.
