THREE-DIMENSIONAL DISTANCE MEASURING CAMERA
Document Type and Number:
WIPO Patent Application WO/2020/130440
Kind Code:
A1
Abstract:
The present invention relates to a three-dimensional distance measuring camera comprising: a light source for emitting light at an object; an image sensor for recognizing light reflected from the object; and a control IC for controlling operations of the light source and the image sensor, wherein the control IC performs control so that the image sensor acquires at least one piece of image information in a first image acquisition section without emission from the light source, and performs control so that the exposure time of the image sensor in a second image acquisition section after the first image acquisition section is different from the exposure time in the first image acquisition section. According to the present invention, a distance error caused by ambient light such as sunlight can be minimized in a photographing process of a camera using a light source, such as a three-dimensional distance measuring camera.
