Title:
DISTANCE MEASUREMENT CAMERA
Document Type and Number:
WIPO Patent Application WO/2020/008832
Kind Code:
A1
Abstract:
A distance-measurement camera 1 comprises: a first optical system OS1 for forming a first subject image; a second optical system OS2 for forming a second subject image; an image-capture unit S for capturing the first subject image and the second subject image; and a distance calculation unit 4 for calculating a first candidate of the distance to a subject 100 on the basis of an image magnification ratio of the magnification of the first subject image and the magnification of the second subject image as captured by the image-capture unit S, and furthermore calculating a second candidate of the distance to the subject 100 on the basis of translation parallax between the first subject image and the second subject image. The distance calculation unit 4 selects either the first candidate or the second candidate as the distance to the subject 100, the selection being made in accordance with a prescribed condition.
