The on-vehicle camera plays an important role in realizing ADAS and automatic driving. The application of a car panoramic camera system with a car camera can greatly improve driving safety and convenience. The panoramic image system Chinese can also be called a 360 degree panoramic image system, or simply MVCS (MulTI-View Camera System). The panoramic view system provides car drivers with more intuitive assistance driving image information, which can quickly and accurately find the situation that is difficult to be observed near the vehicle and achieves accurate driving control, especially for novice drivers, which can improve driving safety and Reduce unnecessary scratches.
The panoramic view system sets up 4 to 8 wide-angle high-sensitivity cameras around the vehicle to cover all the field of view of the vehicle's surroundings, and converts the collected parts into digital information and sends them to the video synthesis and processing through the images of the front, rear, left and right of the car collected at the same time. Components, after image processing unit distortion reduction → view angle conversion → image splicing → image enhancement, conversion into analog signal output, generating a 360-degree body top view, and finally displayed on the center console screen, allowing the driver to clearly see the presence of the vehicle periphery Obstacles and understand the relative position and distance of obstacles to help drivers easily park their vehicles.
While displaying the panorama, it is also possible to display a single view of any of the parties and use the ruler line to accurately locate the position and distance of the obstacle. ADAS collects vehicle peripheral assisted safe driving by controlling the body camera, and the panoramic camera system securely parks by controlling the body camera to collect the influence of the vehicle. The two systems operate independently and throughout the journey.
The panoramic system perspective will dynamically move according to the driving trajectory, providing a 360-degree picture around the vehicle. Typically, four to five high-definition-range (HDR) 1-megapixel cameras are deployed using cost-effective links such as LVDS or Fast Ethernet. Video compression is generally used to reduce the required communication bandwidth and reduce cabling requirements (for example, unshielded twisted pair or coaxial cable can be used). Other system requirements include a multi-port LVDS or Ethernet switch, a power supply, an integrated DRAM for fast access to external memory, and an embedded flash memory to reduce system cost.
