Three-dimensional reconstruction precision testing method and device and electronic equipment

Abstract

The invention discloses a three-dimensional reconstruction precision testing method and device and electronic equipment, and relates to the technical field of high-precision maps. The method comprisesthe steps that three-dimensional coordinates of a first object and a second object in an image sequence in visual point cloud are acquired, the visual point cloud is obtained through three-dimensional reconstruction, and the first object and the second object are objects existing in a high-precision map; calculating a similarity transformation matrix between the visual point cloud and the high-precision map according to the three-dimensional coordinates of the first object in the visual point cloud and the three-dimensional coordinates of the first object in the high-precision map; performingcoordinate transformation on the three-dimensional coordinates of the second object in the visual point cloud according to the similarity transformation matrix to obtain first three-dimensional coordinates of the second object; and calculating the precision of three-dimensional reconstruction according to the error between the first three-dimensional coordinate and the three-dimensional coordinate of the second object in the high-precision map. According to the method, existing high-precision map data are fully utilized, only a small amount of calibration needs to be carried out on the imagesequence, and the three-dimensional reconstruction precision test efficiency can be improved.

Description

technical field [0001] The present application relates to image processing technology, in particular to the field of high-precision map technology, and in particular to a three-dimensional reconstruction accuracy test method, a three-dimensional reconstruction accuracy test device, and electronic equipment. Background technique [0002] At present, the 3D image reconstruction technology can be used in high-precision map applications. For example, the image sequence is collected by an image acquisition device, and the image sequence is modeled in 3D to generate a visual point cloud. The visual point cloud can be fused with the high-precision map to update HD map. Since high-precision maps have high requirements for the accuracy of visual point clouds, it is necessary to test the accuracy of 3D reconstruction to ensure the fusion accuracy of visual point clouds and high-precision maps. At present, professional equipment is generally used to survey and map the scene, and the s...
