Problems solved by technology
[0003] When constructing a map through the above method, the cost of collecting data and maintaining the map is relatively high, and it is difficult to apply it on a large scale. If a monocular camera is used for 3D scene reconstruction, it will be affected by factors such as camera imaging quality and positioning accuracy, resulting in the final The reconstructed scene has scale drift or the reconstructed map has relatively low accuracy

The embodiment of the invention provides a map generation method and device, computer equipment and a storage medium, and the method comprises the steps: determining at least one feature point pair based on the attribute information of a feature point included in a reference road image and the attribute information of a feature point included in a reference road image; reference road images for each, according to the three-dimensional position information of the first feature point in the reference road image in the virtual three-dimensional space, the two-dimensional position information of the first feature point in the reference road image in the reference road image and the two-dimensional position information of the second feature point in the reference road image in the reference road image, obtaining a three-dimensional position of the first feature point in the reference road image; determining first three-dimensional position information of a second feature point in the reference road image; respectively determining second three-dimensional position information of the ground traffic elements in the virtual three-dimensional space from the reference road image and each reference road image; and generating a map for the target road based on the determined first three-dimensional position information and second three-dimensional position information.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular, relates to a map generation method, device, electronic equipment and storage medium. Background technique [0002] When constructing a map, a special collection vehicle is generally used, which is equipped with a laser radar and a positioning module, etc., to obtain the pose of the camera and the precise distance from the object to the camera, and construct Figure three three-dimensional scene, or use a multi-eye camera, obtain the depth of field through calibration, that is, the distance from the object to the camera, solve the camera pose, and construct the ground Figure three dimension scene. [0003] When constructing a map through the above method, the cost of collecting data and maintaining the map is relatively high, and it is difficult to apply it on a large scale. If a monocular camera is used for 3D scene reconstruction, it will be affected by facto...
