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.

Claim (Index 23):
A positioning processing method for the spatial positioning device of  claim 15 , the method comprising the steps of:\n acquiring images collected by the set of cameras arranged horizontally and the set of cameras arranged vertically at the same time point, respectively; calculating a horizontal pixel-value difference (PVD) between a pair of pixels indicating the same feature in the same object according to the images collected by the set of cameras arranged horizontally, and calculating a vertical PVD between a pair of pixels indicating the same feature in the same object according to the images collected by the set of cameras arranged vertically; calculating horizontal PVDs corresponding to other pixels in the images collected by the set of cameras arranged horizontally according to the horizontal PVDs between pairs of pixels, and calculating vertical PVDs corresponding to other pixels in the images collected by the set of cameras arranged vertically according to the vertical PVDs between pairs of pixels; according to the horizontal PVD corresponding to each pixel in the images collected by the set of cameras arranged horizontally, calculating a depth value as a horizontal depth value, and according to the vertical PVD corresponding to each pixel in the images collected by the set of cameras arranged vertically, calculating a depth value as a vertical depth value; and calculating according to the horizontal and vertical depth values to obtain spatial position coordinates of a corresponding feature in the horizontal and vertical directions.
