Title:
奥行取得装置、奥行取得方法およびプログラム
Document Type and Number:
Japanese Patent JP6990859
Kind Code:
B2
Abstract:
A depth acquisition device (1) capable of accurately acquiring a depth of a subject of an image includes a memory (200) and a processor (110a). The processor (110a) performs: acquiring, from the memory (200), intensities of infrared light which have been emitted from a light source and are measured by imaging performed by receiving the infrared light reflected on a subject by pixels in an imaging element; generating a depth image by calculating a distance to the subject as a depth for each pixel based on an intensity received by the pixel; acquiring, from the memory (200), a visible light image generated by imaging a substantially same scene as that of an infrared light image, with visible light from a substantially same viewpoint and at a substantially same timing as those of imaging the infrared light image which is generated by the imaging based on the intensities of the infrared light received by the pixels; detecting, from the visible light image, an edge region including an edge along a direction perpendicular to a direction of movement of the visible light image; and correcting, in the depth image, a depth of a target region corresponding to the edge region in the depth image.
