Document Type and Number:
WIPO Patent Application WO/2021/115236
Kind Code:
A1
Abstract:
A method and a device for positioning by means of scene marking. The device for positioning by means of scene marking comprises: a feature position, a feature picture, and a software system. The feature position is a site, selected in a scene, where the feature picture should be arranged or the feature picture should be collected. The feature picture is a picture obtained by photographing, or a printed picture for posting or a laser picture, and is used for marking image information, for identification, of coordinates and relevant information in a target area. The software system is a system for storing a collision information table of the target area, loading the collision information table of the target area, and verifying the rationality of collision information collection in the target area so as to reduce human errors. The method for positioning by means of scene marking can collect an image feature or arrange a feature picture on a ceiling so as to reduce possible blocking of part of a scene by surrounding moving objects. The method for positioning by means of scene marking can verify the possible passage of various vehicles by adding a bounding box of a specified size.
