A car door opening warning system and method based on panoramic surround view image processing

Abstract

The present invention relates to a car door opening warning system and method based on panoramic view image processing. The system includes an AVM controller, a car door detection module, a camera module and an entertainment display screen; When the CAN network signal of the current vehicle is judged to be open or closed, a panoramic bird’s-eye view is generated on the entertainment display screen according to the image information of the four directions of the vehicle collected by the camera module, and the correspondence is simulated on the car model of the panoramic bird’s-eye view according to the CAN network signal The door is opened or closed, and at the same time, according to the image information corresponding to the opened or closed door of the vehicle, it is judged whether there is an obstacle in the active area when the door is opened or closed. If there is an obstacle, an early warning message is sent to the entertainment display. Remind the user that they may touch obstacles during the opening or closing of the door, avoiding the possibility of touching obstacles during the opening or closing of the door.

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.
