Title:
PLANE GEOMETRY CONSISTENCY DETECTION METHOD, COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/168620
Kind Code:
A1
Abstract:
The present application provides a plane geometry consistency detection method, a computer device, and a storage medium, wherein the method comprises obtaining a first normal vector set and a second normal vector set, and a first distance set and a second distance set; obtaining each pair of first normal vectors and a pair of second normal vectors matching their angles, and calculating a first rotation matrix and a first projection matrix thereof; converting the first projection matrix into rotation vectors to form a rotation vector set; clustering the elements in the rotation vector set, and generating a first normal vector sequence and a second normal vector sequence according to the elements in a first target classification of the most elements; calculating a second rotation matrix by which the first normal vector sequence is converted into the second normal vector sequence and taking its second projection matrix as a target rotation matrix; in addition, obtaining a distance difference set through the first and second distance sets, and clustering to obtain a second target classification and calculating the first and second distances of the elements and the corresponding second normal vector to obtain a target translation matrix. The solution of the present application implements highly consistent and rapid plane mapping under different coordinate systems.
