Abstract

The embodiment of the invention provides a map generation method and device, electronic equipment and a computer storage medium. The method comprises the steps that a sequence of road images and a sequence of track points of an acquisition device of the road images are acquired, and the track points are used for indicating the pose of the acquisition device in a world coordinate system when the corresponding road images are acquired; obtaining a road surface area from the road image; acquiring a first space coordinate of a first pixel of the road surface area in a coordinate system of an acquisition device; and according to the pose of the track point corresponding to the road surface area to which the first pixel belongs, determining a second space coordinate of a mapping point, mapped into the world coordinate system, of the first pixel, so as to generate a point cloud map according to the second space coordinate. The method is better in use effect.

Description

technical field [0001] The embodiments of the present application relate to the field of map technology, and in particular, to a map generation method, apparatus, electronic device, and computer storage medium. Background technique [0002] In the field of road maintenance and repair, it is necessary to regularly inspect the road surface for cracks. The existing pavement crack inspection methods usually collect a series of images of the pavement and the surrounding environment through a camera, and manually inspect the pavement for cracks based on the images. This has some shortcomings, such as low detection efficiency and difficulty in obtaining the exact geographic location of cracks. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present application provide a map generation solution to at least partially solve the above problems. [0004] According to a first aspect of the embodiments of the present application, a method for generating a map...
