Document Type and Number:
WIPO Patent Application WO/2020/017334
Kind Code:
A1
Abstract:
The present invention provides a vehicle-mounted environment recognition device that makes geometric camera calibration easy even if a single object shown in images photographed using a plurality of cameras has significantly different appearances in the images. The present invention comprises a first camera 100, a second camera 110, and a control device 10 for extracting a plurality of corresponding points after viewpoint conversion in which a first image imaged by the first camera and a second image imaged by the second camera are converted into images from a common viewpoint through the transformation of at least one from among the first image and second image and using the coordinates of the plurality of corresponding points in the first image and second image before viewpoint conversion to geometrically calibrate the first camera and second camera.
