Title:
WRONG-WAY TRAVEL DETERMINATION DEVICE, WRONG-WAY TRAVEL DETERMINATION METHOD, AND WRONG-WAY TRAVEL DETERMINATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/085226
Kind Code:
A1
Abstract:
This wrong-way travel determination device is configured to execute wrong-way travel determination processing (S20, S22) for determining, on the basis of a prescribed object (52) represented in image data corresponding to the output of a camera (10) directed to the forward direction of a vehicle, whether the vehicle is traveling the wrong-way. The prescribed object is an object disposed periodically along a merging road that merges with the road on which the vehicle is traveling. The wrong-way travel determination processing includes at least one of two processes, namely: a process of determining that the vehicle is traveling the wrong-way if the prescribed object is captured in each of two regions, namely a left side region and a right side region in a horizontal direction, represented in the image data; and a process of determining that the vehicle is traveling the wrong-way if the prescribed object is displaced from one end to the other end of the left-right ends of a region represented in the image data.
