Document Type and Number:
Japanese Patent JP7447916
Kind Code:
B2
Abstract:
An imaging device (1) according to the present disclosure includes an imaging unit (2), a signal separating unit (5), a normal line calculating unit (6), and a distance estimation unit (7). The imaging unit (2) includes a plurality of polarization lights (21 to 24) having different polarization directions of light emitted to a subject and a polarization sensor (11) and captures an image of the subject that is simultaneously irradiated with the light from the plurality of polarization lights (21 to 24). The signal separating unit (5) separates pixel signals corresponding to each of the polarization directions from the image captured by the imaging unit (2) and generates an image for every polarization direction. The normal line calculating unit (6) calculates a normal line on a surface of the subject from the image for each of the polarization directions by photometric stereo. The distance estimation unit (7) estimates the shape of the subject on the basis of the normal line calculated by the normal line calculating unit (6).
