Overview
CandidTech's ADAS AVM solution goes beyond the basic 360 - degree
functionality. In addition to providing a comprehensive 360 - view
around the vehicle, it also supports various extended ADAS
features.
It offers ADAS functions like the "transparent vehicle bottom", which gives drivers a clear view of the area beneath the
vehicle, enhancing safety during parking or low - speed maneuvers.
The moving object detection(MOD) function can quickly identify any moving objects in the vehicle's
surrounding, helping prevent collisions. Moreover, the lane departure warning(LDWS) can alerts the driver when the vehicle is about to deviate from
its lane without signaling, and these features are customizable, allowing users to configure
according to the specific needs and preferences.
CandidTech's 360 vehicle camera system is consisted of one
Electronic Control Unit(ECU) and four cameras. The ECU will process
the images which captured by the four cameras and then output to
the car display screen.

BASIC FUNCTIONS
1) 2D Around View Display
360 car view camera will splice the images which captured by 4
cameras into a 2D 360 degree around view seamlessly, so the driver
could see the environment around the car easily.
2) Different Direction Image Display
360 degree bird view camera system can display images from
different direction.
3) 3D Around View Display
4) View Shifts
The system will shift different view according to turn signals,
gear shifts or the AVM button on center control of the car.
5) Static Assisted Line or Dynamic Assisted Line for Parking
When driver shifts the gear to "R", the system will display 2D
around view and rear view. In the mean time, the static assisted
line or dynamic assisted line will show up to assist driver for
parking or reversing.
Remark: The assisted lines are optional, customer can choose static
assisted line or dynamic assisted line as demand.
EXPANDING ADAS FUNCTIONS
1) Full-terrain Perspective Under the Car
The System can display wide-angle view in tripartite picture, the
horizon view is closed to 180°. It helps driver to check if there
is other vehicle approaching when driving out of parking spot.
2) Ultrasonic Radar Distance Warning
CandidTech 360 blind spot camera system is not included radar,
vehicle must be equipped with radar to achieve this function. Or we
could after load the radar as per customer's demand.
3) DVR Function
CandidTech 360 car view camera system can storage the videos from
the 4 cameras and output to a 4 in 1 image for DVR function. It
will keep the fisheye images as they are without calibration, for
providing true and legal video evidence purposed.
Supported storage card: TF card, FAT32 format, maximum 32GB.
4) Moving Object Detection(MOD)
When parking or car starting, through image recognition technology
the AVM system can detect the moving object around the car and warn
the driver to adjust driving behavior.
5) Lane Departure Warning System(LDWS)
When the vehicle speed is faster than 50km/h(speed customizable),
the AVM system will identify the standard lane line according to
its 2D around view.
If the driver is deviating from the original lane
unconsciously(without using the turn signal), the system can give
an alert on 0.5 seconds before the departure of the lane, to remind
the driver for the lane departure situation of the vehicle,
providing more response time for the driver, greatly reducing the
collision caused by lane departure.
What are the main advantages of CandidTech's to develop the 360 AVM
System?
As a 10-year experienced Tier1/Tier2 supplier for 360 degree
surround view automotive OEM/ODM parts, we have mastered advanced
sensor fusion technology. We support integrate multiple high -
resolution cameras, ultrasonic sensors and sometimes even radar
sensors.
Our in - house developed high - performance image processing
algorithms are a key advantage. These algorithms can quickly
process the large amount of image data captured by the cameras.
They enhance image quality, correct for lens distortion, and
perform real - time stitching of multiple camera views to create a
seamless 360 - degree bird's - eye view. This ensures that the
driver can clearly see all potential obstacles and hazards around
the vehicle, even in complex lighting conditions.
We offer highly customized software solutions tailored to the
specific needs of different automotive manufacturers. Our software
can be integrated with the vehicle's existing in - car
entertainment system, driver - assistance systems, and ECU. This
allows for seamless operation and control of the 360 - degree
surround - view system.
We ensure reliable connectivity and high speed data transmission.
Using advanced communication protocols like GMSL (Gigabit
Multimedia Serial Link), we can transfer large amounts of image
data from the cameras to the central processing unit in real time
without signal loss or delay. This is crucial for the smooth
operation of the system, especially when it comes to real - time
applications like dynamic parking guidance.
Our products are designed to have excellent environmental
adaptability. They can withstand a wide range of temperatures, from
extremely cold to very hot conditions. With high - level waterproof
and dust - proof ratings (IP67 or above), our cameras and sensors
can function normally in various harsh weather and road conditions.
This ensures the long - term reliability and stability of the 360 -
degree surround - view system, which is highly valued by automotive
OEMs.
