Car cameras play an important role in realizing ADAS and autonomous driving.
The Car cameras plays an important role in the realization of ADAS and automatic driving. The vehicle panoramic image system composed of the Car cameras can greatly improve the safety and convenience of driving. Chinese panoramic image systems can also be called 360° panoramic image systems (MVCs).
The panoramic surround view system provides car drivers with more intuitive driving image information, can quickly and accurately find difficult-to-observe situations near the vehicle, and achieve precise driving control, especially for novice drivers, which can improve driving safety and reduce unnecessary Scratches. The panoramic surround view system covers all fields of vision around the vehicle by setting 4 to 8 wide-angle and high-sensitivity cameras around the vehicle. Through the images collected from the front and rear of the vehicle at the same time, the collected parts are converted into digital information and sent to the video synthesis processing part. After the distortion reduction of the image processing unit-perspective conversion-image stitching-image enhancement, the system is converted into a model, and the analog signal output generates a 360-degree top view of the car body, which is finally displayed on the center console screen to make the driver clear Groundly check whether there are obstacles around the vehicle, understand the relative direction and distance of the obstacles, so as to help the driver to park easily.
In the panoramic display, you can also display a single view on either side, and use the ruler line to accurately locate the position and distance of the obstacle. Adas collects the safe driving information of surrounding vehicles by controlling the body camera, and the panoramic car camera system collects the surrounding impact information of the vehicle by controlling the body camera to realize safe parking. These two systems work independently during the entire driving process. The perspective of the panoramic system will dynamically move according to the driving trajectory, providing a 360-degree picture of the vehicle's surroundings. Typically, LVDS or Fast Ethernet and other cost-effective links are used to deploy 4 to 5 high dynamic range (HDR) 1 million pixel cameras. Video compression is often used to reduce the required communication bandwidth and cabling requirements (for example, unshielded twisted pair or coaxial cable can be used). Other system requirements include multi-port LVDS or Ethernet switches, power supplies, integrated DRAM for fast access to external memory, and embedded flash to reduce system costs.
