Abstract

The invention relates to a method and a device for generating a car backing assisting line. The method includes: acquiring preset amount of first key points on the axle linear trajectory before car turning in a three-dimensional coordinate system; determining second key points corresponding to the first key points after car turning according to the turning angle of a car; determining a first group of third key points and a second group of third key points corresponding to the preset amount of second key points according to the axle curve trajectory; projecting the first group of third key points and the second group third key points to obtain projecting points; connecting the projecting points to generating the car backing assisting line. The method is simple in algorithm and good in achievable effect, and computing speed and the processing efficiency of a car backing assisting system are increased.

Description

technical field [0001] The present invention relates to the technical field of reversing assistance, in particular to a method and device for generating a reversing auxiliary line. Background technique [0002] As a practical vehicle configuration, the reversing assistance system can help the driver accurately grasp the road conditions behind the vehicle in the form of sound and images when the driver is reversing, and eliminate potential safety hazards caused by blind spots in the vehicle rearview mirror. [0003] With the application of modern electronic technology in vehicle systems, the visual reversing image assistance system has replaced the traditional reversing radar assistance system. The reversing image assist system adopts a far-infrared wide-angle camera device installed behind the vehicle. Through the display screen in the vehicle, it can clearly display the obstacles behind the vehicle, providing convenience for the driver during the reversing process. [0004...
