Problems solved by technology

After the completion of photogrammetry, these code points need to be recovered. The process of layout and recovery is very time-consuming, and if the position of the code points is moved during the shooting process, it will cause measurement failure or decrease in measurement accuracy. Therefore, it is urgently needed A new photogrammetry method to solve the above problems

Abstract

Embodiments of the present disclosure relate to a photogrammetry method, device, equipment, and storage medium. By acquiring multiple sets of synchronous images of an object to be measured with multiple marker points on the surface continuously captured by a multi-eye camera, extract the synchronous images in each group of synchronous images. The coordinates of the image point corresponding to the marker point, and according to the calibration data of the multi-eye camera and the coordinates of the image point, reconstruct the first three-dimensional coordinates of the marker point corresponding to the image point, and obtain multiple groups of three-dimensional marker points; for multiple groups of three-dimensional marker points Perform tracking and splicing processing to obtain the global frame of the marker points corresponding to the marker points on the surface of the object to be measured and the numbers of the 3D marker points in each group in the frame; deduplicate the numbers of the 3D marker points in each group in the frame processing to obtain the unique numbers of the three-dimensional marker points in each group in the frame. The solution provided by this application can realize photogrammetry without arranging code points or only need to arrange a very small number of code points, which reduces the manual workload and improves measurement efficiency and accuracy.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of photogrammetry, and in particular, to a photogrammetry method, device, equipment, and storage medium. Background technique [0002] At present, in photogrammetry based on monocular cameras, it is generally necessary to manually set a large number of code points on the surface of the object to be measured, and some experience is required in the process of arrangement, such as the density distribution of the arrangement, spatial position relationship, etc. After the completion of photogrammetry, these code points need to be recovered. The process of layout and recovery is very time-consuming, and if the position of the code points is moved during the shooting process, it will cause measurement failure or decrease in measurement accuracy. Therefore, it is urgently needed A new photogrammetry method is proposed to solve the above problems. Contents of the invention [0003] In order ...
