Spatial position identification method, device and system and storage medium

The invention relates to the technical field of engineering application, in particular to a spatial position identification method, device and system and a storage medium, and can solve the problem that the spatial position of a target cannot be determined in an engineering project with an existing common camera to a certain extent. By acquiring at least two calibration images including a preset space, two-dimensional calibration images including the preset space under different shooting angles can be acquired; further based on the coordinates of the same calibration points in each calibration image, a calibration vector can be determined, and a hypersphere of a preset space can be determined by enabling the calibration vector to pass through a preset conversion model; by obtaining the to-be-measured target, the distance between the to-be-measured target and the center of the hypersphere can be determined, the spatial position of the to-be-measured target is further determined, and the spatial position of the
