Abstract

The embodiment of the invention provides a reversing trajectory display method and device. The method comprises the following steps: when a reversing process of a vehicle is started, acquiring a current turning angle of the vehicle; acquiring a corresponding reversing trajectory from a trajectory database according to the turning angle, wherein the trajectory database is a database which is acquired in an offline manner and has reversing trajectories corresponding to all turning angles within a preset turning angle range; displaying the acquired reversing trajectory on a reversing video picture. According to the reversing trajectory display method and device, the trajectory database which is acquired in the offline manner and has the reversing trajectories corresponding to all the turning angles within the preset turning angle range is adopted, and when the reversing process is started, the corresponding reversing trajectory is acquired from the trajectory database according to the current turning angle of the vehicle, and is displayed on the reversing video picture, so that a process of calculating the reversing trajectory in hardware in real time in an online manner in the prior art is eliminated, and the processing pressure of the hardware is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, in particular to a method and device for displaying a reversing track. Background technique [0002] At present, parking spaces are tight and parking is becoming more and more difficult. As a cheap and effective reversing assistance system, reversing image is more and more common in mid-to-high-end models. Using the reversing assist system can not only see the image information behind the vehicle, but also predict the vehicle’s reversing trajectory based on the vehicle’s steering wheel steering angle, vehicle feature information, and camera function information, and display the reversing trajectory on the image information. Drivers can judge in advance whether they will collide with obstacles by watching the displayed images, which greatly reduces the possibility of accidents. [0003] The current reversing trajectory display solution is mainly applicable to the situati...
