Title:
SPATIAL INFORMATION DETECTION DEVICE AND PERSON LOCATION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/190772
Kind Code:
A1
Abstract:
A spatial information detection device comprises an acquisition unit, a reference setting unit, and a pixel computation unit. The acquisition unit acquires three-dimensional data relating to a subject space which a measurement device has measured. The pixel computation unit sets a plurality of small planes in a region of interest in the subject space, and by using the three-dimensional data in the regions of interest, derives for each small plane a facing in a device coordinate plane which is defined in the measurement device and a distance from the measurement device. The reference setting unit defines a reference plane for measuring the subject space, on the basis of the facing and distance which the pixel computation unit has derived for each small plane.
