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

The embodiment of the invention relates to a photogrammetry method and device, equipment and a storage medium, and the method comprises the steps: obtaining a plurality of groups of synchronous images of a to-be-measured object which is continuously shot by a multi-view camera and is provided with a plurality of mark points on the surface, and extracting the coordinates of image points corresponding to the mark points in each group of synchronous images; according to the calibration data of the multi-view camera and the coordinates of the image points, obtaining first three-dimensional coordinates of the mark points corresponding to the image points through reconstruction, and obtaining multiple sets of three-dimensional mark points; tracking and splicing the plurality of groups of three-dimensional mark points to obtain a mark point global framework corresponding to the mark points on the surface of the object to be measured and serial numbers of the three-dimensional mark points in each group in the framework; and performing inter-group duplicate removal processing on the serial numbers of the three-dimensional mark points in each group in the frame to obtain the unique serial numbers of the three-dimensional mark points in each group in the frame. According to the scheme provided by the invention, the photogrammetry can be realized without arranging coding points or only arranging a very small number of coding points, so that the manual workload is reduced, and the measurement efficiency and accuracy are improved.
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 ...
