Abstract: The present invention discloses a spatial positioning device, and a positioning processing method and device. The spatial positioning device comprises a set of cameras arranged horizontally and a set of cameras arranged vertically, wherein each set comprises at least two cameras with the same parameters including an image resolution, a camera lens angle in the horizontal direction and a camera lens angle in the vertical direction; and the at least two cameras in the set of cameras arranged horizontally are aligned in the horizontal direction, and the at least two cameras in the set of cameras arranged vertically are aligned in the vertical direction. In the spatial positioning device provided by the present invention, as the sets of cameras are arranged in the different directions, it is possible to effectively reduce or even eliminate the number of blind spots in the process of image shooting in the single direction. In addition, the additionally arranged set of cameras arranged vertically may also improve the measurement accuracy of a spatial position coordinate of an object in the vertical direction, so as to improve the positioning accuracy of the object.
