Title:
OPTICAL DISTANCE MEASUREMENT DEVICE AND METHOD FOR OPTICAL DISTANCE MEASUREMENT
Document Type and Number:
WIPO Patent Application WO/2020/235411
Kind Code:
A1
Abstract:
An optical-distance measurement device (20) forms an image of reflected light corresponding to pulsed light that is emitted from a light-emitting section (40) to a predetermined range on pixels (66) that includes an array of a plurality of subpixels (69, s1-s9), each of which can detect the reflected light, and the optical-distance measurement device (20) causes a timing control section (170) to perform detection of reflected light repeatedly made by at least some of the subpixels at some time intervals and detection of reflected light repeatedly made by the other subpixels at some time intervals in different phases. By using the result of detection repeatedly at time intervals on the small pixels, a specifying section (100) specifies the spatial position of an object (OBJ1), the position including a distance to the object present in a predetermined range.
