Abstract

The invention discloses a vehicle three-dimensional model obtaining method and device, electronic equipment and a storage medium, and relates to the field of automatic driving. According to the specific implementation scheme, the method includes: obtaining an image collected in the vehicle driving process, wherein the image comprises components of other vehicles; according to the two-dimensional coordinates of the component in the image and the three-dimensional coordinates of a preset component corresponding to the component in a preset three-dimensional model, obtaining conversion coefficients of the two-dimensional coordinates and the three-dimensional coordinates; and generating three-dimensional models of other vehicles according to a preset three-dimensional model and the conversion coefficient. According to the method, the three-dimensional model of the vehicle in the image can be constructed according to the mapping of the preset three-dimensional model and the coordinates of the components in the acquired image, and the accuracy of the three-dimensional model can be improved.

Description

technical field [0001] The present application relates to the field of automatic driving, and in particular to a method, device, electronic device and storage medium for acquiring a three-dimensional model of a vehicle in the field of automatic driving. Background technique [0002] Self-driving vehicles need real-time three-dimensional perception of the surrounding environment during driving, such as real-time acquisition of three-dimensional models of vehicles, green belts, traffic signs, etc. in the surrounding environment, in order to make correct driving decisions. [0003] In the prior art, the self-driving vehicle can obtain the two-dimensional image of the surrounding environment in real time, and obtain the distance between each position of the vehicle in the two-dimensional image and the self-driving vehicle according to the two-dimensional image and the preset depth model network, so as to obtain the two-dimensional The 3D point cloud data of the vehicle in the 3D...
