Vehicle door opening early warning system and method based on full-view around view image treatment

Abstract

The invention relates to a vehicle door opening early warning system and method based on full-view around view image treatment. The system comprises an AVM controller, a vehicle door detection module,a camera module and a recreation display screen. The AVM controller is used for generating the full-view aerial view on the recreation display screen according to vehicle four-direction image information collected by the camera module when it is judged that a current vehicle door is opened or closed according to CAN network signals sent by a vehicle door detection controller, opening or closing of the corresponding vehicle door is simulated on a vehicle model of the full-view aerial view according to the CAN network signals, whether obstacles exist in the moving area where the vehicle door isopened or closed is judged according to the image information corresponding to the vehicle opened or closed vehicle door, and if the obstacles exist, early warning information is sent to the recreation display screen. A user is reminded that the vehicle door is likely to touch the obstacles in the opening or closing process, and the situation that the vehicle door touches the obstacles in the opening or closing process is avoided.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a car door opening warning system and method based on panoramic surround view image processing. Background technique [0002] Panoramic Surround View System (AVM), which collects image information in four directions of front, rear, left, and right of the vehicle through a wide-angle camera, and then sends it to the central controller. After camera parameter correction, lens distortion correction, bird's-eye view angle conversion, white Balance matching and image stitching processing, and finally display a panoramic bird's-eye view picture on the monitor that can intuitively monitor the surrounding environment of the vehicle, which can effectively reduce blind spots and improve safety. [0003] Normally, when the vehicle door is opened, the car model in the AVM screen (usually the panoramic bird's-eye view on the left) will simulate the current door opening state. However, sin...

Problems solved by technology

[0004] For this reason, it is necessary to provide a car door opening warning system and method based on panoramic view image processing to solve the problem that the obstacle detection when the car door is opened cannot be realized in the existing panoramic view system, which may cause obstacle collision after the real car door is opened.
