Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the structure related to the present invention.

[0025] Exemplary, see figure 1 , figure 1 Is a schematic diagram of trajectory generation provided by an embodiment of the present invention, figure 1 In simulating the actual reversing process to establish a coordinate system, take a wheel at the rear of the car as an example, the projection of the wheel on the ground is the X axis, the projection of the wheel axis on the ground is the Y axis, and the corresponding steering wheel angle is 0° when reversing in a straight line. It is defined that the steering wheel angle corresponding to right reversing is p...

Abstract

The embodiment of the invention discloses a trajectory generation method, a device, a trajectory analyzer and a storage medium. The method comprises the following steps of Acquiring a rear view imageafter reversing at a first steering wheel angle by sampling the technical proposal, wherein the range of the rear view image includes a road surface pressed by a wheel when reversing; Extracting a plurality of trajectory identification points included in the rear view image; Generating a first dynamic back-up trajectory corresponding to a first steering wheel angle according to the trajectory identification point; Outputting a second dynamic reverse trajectory corresponding to a second steering wheel angle according to the first dynamic reverse trajectory. By sampling in the actual reversing scene, the invention makes the precision of the generated dynamic reversing trajectory higher, thereby realizing safer and more convenient assistance to the driver in reversing.

Description

Technical field [0001] The invention relates to auxiliary equipment and related technologies when a vehicle is reversing, in particular to a trajectory generating method, device, trajectory analyzer and storage medium. Background technique [0002] In daily life, a car is a commonly used means of transportation, which greatly facilitates people's travel. With the rapid development of the automobile industry, the corresponding reversing assist technology has also emerged. The reversing assist device is a safety assist device when the car is reversing. [0003] Nowadays, the mainstream reversing assist device combines the reversing camera and the on-board display. The on-board display can display the real-time video of the rear reversing camera when reversing, and it can also display the dynamic reversing trajectory for the driver's reference, so as to facilitate the driver to reverse , And make reversing safer. However, the dynamic reversing trajectory is generated by a preset alg...
