Abstract

The invention provides a transverse positioning method and vehicle-mounted equipment, and the method comprises the steps: obtaining a first image shot by a camera, and enabling the first image to comprise a wall corner line of at least one side of a vehicle; Inputting the first image into a wall corner line detection model to obtain at least one first wall corner line feature point in the first image, the wall corner line detection model being a network model trained by using a convolutional neural network; And calculating the transverse distance between the vehicle and the wall corner line according to the first coordinate information of the at least one first wall corner line feature point. The reliability of vehicle transverse positioning is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a lateral positioning method and vehicle-mounted equipment. Background technique [0002] With the development of smart cars, autonomous driving technology is becoming more and more mature. In the valet parking scenario of the valet parking service, especially in the Valet parking underground garage scenario, it is usually necessary to perform lateral positioning of the vehicle to ensure the safe driving of the vehicle. In the prior art, lane lines are usually used for positioning. However, in the Valet parking underground garage scenario, there may be no lane lines or the lane lines may be worn, which makes the reliability of vehicle lateral positioning low. Contents of the invention [0003] Embodiments of the present invention provide a lateral positioning method and vehicle-mounted equipment, so as to solve the problem of low reliability of vehicle lateral positioning ...
