Title:
IMAGE RECOGNITION DEVICE AND DISTANCE IMAGE GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/180391
Kind Code:
A1
Abstract:
This image recognition device (A) is provided with: a light source (1) which emits light emission pulses to a measurement space; an image generating unit (4) which generates a distance image on the basis of reflected light obtained by a light receiving element (2); a reflectance calculation unit (5) which calculates a correction coefficient corresponding to the reflectance of each measuring section; and a light emission pulse control unit (6) which controls the number of light emission pulses emitted from the light source according to the correction coefficient of each measuring section.
