Title:
IMAGE PROCESSING DEVICE FOR CORRECTING DISTORTION IN OMNIDIRECTIONAL IMAGE AND AUTONOMOUS TRAVEL ROBOT EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2018/216710
Kind Code:
A1
Abstract:
In the present invention, a robot acquires an omnidirectional image 170 by means of an omnidirectional camera, and converts the omnidirectional image 170 to a polyhedral image 190. Pixels of the omnidirectional image 170 are projected onto any of the enlarged parallel surfaces 168 forming the polyhedral image 190. By subjecting the multiple enlarged parallel surfaces 168 included in the polyhedral image 190 to an image recognition process, the robot recognizes the external environment, and the behavior characteristics of the robot are changed in accordance with the recognition result. An image conversion unit of the robot sets, as the polyhedral image 190, a collection of images wherein the imaging surface is a rhombicuboctahedron covering the robot from above.
