Abstract
A spatial positioning method, a spatial positioning device, a spatial positioning system, and a computer readable storage medium are disclosed. The spatial positioning method includes: acquiring a two-dimensional image of an object to be positioned having a plurality of marking points, the two-dimensional image comprising a plurality of marking point images in one-to-one correspondence with the plurality of marking points; determining a correspondence between the plurality of marking points and the plurality of marking point images according to a relative positional relationship among the plurality of marking points and a relative positional relationship among the plurality of marking point images; and determining at least one spatial degree of freedom of the object to be positioned according to the relative positional relationship among the plurality of marking points, the relative positional relationship among the plurality of marking point images, and the correspondence between the plurality of marking points and the plurality of marking point images.
