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 27):
The processing device of positioning of  claim 26 , wherein:\n the set of cameras arranged horizontally comprises a first camera and a second camera, and the set of cameras arranged vertically comprises the second camera and a third camera; the image acquisition module is configured to acquire images collected by the first camera, the second camera and the third camera at the same time point, correspondingly, the images being a first image, a second image and a third image; the PVD calculation module comprises a PVD calculation unit and a vertical PVD calculation unit; the PVD calculation unit is configured to compare the first image with the second image, match the same in the horizontal direction to obtain a pair of pixels indicating the same feature in the same object as a pair of horizontal pixels, and determine a horizontal PVD between the pair of horizontal pixels on the first and second images according to the positions of the pair of horizontal pixels on the first and second images; the vertical PVD calculation unit is configured to compare the second image with the third image, match the same in the vertical direction to obtain a pair of pixels indicating the same feature in the same object as a pair of vertical pixels, and determine a vertical PVD between the pair of vertical pixels on the second and third images according to the positions of the pair of vertical pixels on the second and third images; the full pixel matching module comprises a horizontal full pixel matching unit and a vertical full pixel matching unit; the horizontal full pixel matching unit is configured to calculate horizontal PVDs corresponding to other pixels in the first and second images according to the horizontal PVD between the pair of horizontal pixels; the vertical full pixel matching unit is configured to calculate vertical PVDs corresponding to other pixels in the second and third images according to the vertical PVD between the pair of vertical pixels; the depth value calculation module comprises a horizontal depth value calculation unit and a vertical depth value calculation unit; the horizontal depth value calculation unit is configured to calculate a depth value by each pixel as a horizontal depth value according to the horizontal PVD corresponding to this pixel in the first and second images; the vertical depth value calculation unit is configured to calculate a depth value as a vertical depth value according to the vertical PVD corresponding to this pixel in the second and third images; and the coordinate calculation module is configured to calculate spatial position coordinates of the corresponding feature in the horizontal and vertical directions according to the horizontal and vertical depth values.
