Title:
OBJECT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/017336
Kind Code:
A1
Abstract:
The present invention ensures disparity calculation accuracy even if there is vertical-direction image deviation and suppresses performance degradation and processing cost growth. The present invention comprises: an imaging unit 310 for obtaining a plurality of images; a disparity image generation unit for generating a disparity image from images acquired from the imaging unit 310; a reliability calculation unit 342 for using inter-matching-window edge orientations to calculate the reliabilities of the disparities in the disparity image; a reliability calculation execution determination unit 341 for determining whether to execute reliability calculation; and an object detection unit 343 for, if the reliability calculation execution determination unit 341 determines that reliability calculation is to be executed, using the disparity image and reliabilities to detect an object.
