Zusammenfassung: | Embodiments of the present disclosure relate to a photogrammetry method, apparatus and device, and a storage medium. Multiple groups of synchronous images of an object to be measured provided with multiple mark points on a surface continuously photographed by a multi-view camera are obtained, coordinates of image points corresponding to the mark points in each group of synchronous images are extracted, and first three-dimensional coordinates of the mark points corresponding to the image points are reconstructed according to calibration data of the multi-view camera and the coordinates of the image points to obtain multiple groups of three-dimensional mark points; and a mark point global framework corresponding to the mark points on the surface of the object to be measured is constructed based on the multiple groups of three-dimensional mark points. Photogrammetry can be realized without arranging encoded points or only arranging a small number of encoded points, manual workload is reduced, and measurement efficiency and accuracy are improved. |
