Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In the existing dynamic reversing trajectory calibration process, repeated corrections are required during on-site calibration at the parking lot, and the work efficiency is low, and the points taken are not in accordance with the real vehicle rear wheel motion trajectory. There is always a gap between reality and theory. In addition, the reversing camera Distortion exists, resulting in a large error in the reversing trajectory.

Abstract

The invention relates to the technical field of backup trajectory drawing methods, in particular to a dynamic backup trajectory drawing method and device. The method includes the following steps of obtaining a static image displayed by a backup developing display screen when a vehicle is in a static state, setting a linear coordinate form on the ground corresponding to the static image, backing upthe vehicle at a specific backup angle, sequentially collecting a plurality of coordinate points corresponding to vehicle rear wheels on the linear coordinate form from the linear coordinate form, connecting the coordinate points to form an actual backup trajectory, obtaining corresponding positions of the coordinate points in the static image, and connecting the corresponding positions of the coordinate points to form the dynamic backup trajectory. The invention is aimed at providing the dynamic backup trajectory drawing method and device. By means of the technical scheme, the technical problems that an existing dynamic backup trajectory drawing method is low in work efficiency and an actual backup trajectory is large in error are solved.

Description

technical field [0001] The present invention relates to the technical field of a method for drawing a reversing trajectory, in particular to a method and a device for drawing a dynamic reversing trajectory. Background technique [0002] The reversing track is an on-board intelligent system, which is a virtual line road with guiding effect drawn by the computer according to the real-time video screen behind the car observed by the reversing camera. The virtual road is composed of curves, displayed on the car monitor, overlaid on the real road behind the car, to help you plan the reversing route, and it will move left and right according to the rotation of the steering wheel. [0003] The reversing image system needs to calibrate the reversing trajectory line. In order to draw the dynamic reversing trajectory auxiliary line, it is necessary to go to the parking lot for calibration after the mold parts of the prototype car are frozen. The so-called calibration is to spread the...
