Title:
DISTANCE MEASUREMENT DEVICE AND IMAGE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/196087
Kind Code:
A1
Abstract:
This distance measurement device (1) comprises an imaging unit (2) for imaging N (where N is an integer greater than or equal to 2) division images corresponding to N division distances that a distance measurement range has been divided into and a distance image generation unit (8) for generating a distance image from the N division images. The distance image generation unit (8) identifies, from among the division pixels composing the N division images, the division pixels having the maximum signal value from among the N division pixels at the same pixel position and determines that the distance value for a pixel position in the distance image is the value indicating the division distance of the division pixel having the maximum signal value if the maximum signal value is greater than or equal to a threshold or is outside of the measurement range if the maximum signal value is less than the threshold.
