Description of AVM functions
AVM circumnavigation system can provide the video effect of no blind area around the car body during the driver’s driving process, the driver can intuitively see the position of the vehicle and the obstacles around the vehicle, and control the vehicle to park or pass through the complex road surface, effectively reducing the occurrence of scratches, falls, collisions and other accidents. Integrated with the ADAS advanced driver assistance system, it senses the environment around the vehicle and the vehicle through sensors and cameras, providing the driver with reliable alarm and prompt information, making the driving safer.
Off-line calibration (traditional scheme) When the vehicle is off the line, the calibration site is arranged in advance, and the system completes the calibration of the camera by automatically collecting the site information.
On-line Calibration (OTF) When the camera is replaced or the installation position is slightly offset. The system can complete the calibration of the camera by automatically collecting the surrounding scene information, without the need to calibrate the camera by a specific calibration site.
Moving object monitoring(MOD) Through the four-way fisheye camera to identify the moving objects around the body, detect the surrounding environment •Pedestrian Detection(PD) Through the analysis of the image information collected by the camera, the stationary or moving pedestrians (adults, children, etc.) are detected and alerted •Lane departure warning(LDW) Detect the road space behind and on the side of the vehicle and give the driver a warning when the vehicle is approaching •Blind spot detection system(BSD) Through the left and right rear three language camera monitoring, monitoring the rear obstacles of the vehicle timely alarm signals and avoid traffic accidents
