Abstract

The invention relates to the technical field of robot autonomous navigation, in particular to an automatic image cutting method based on a branch and bound method. The automatic image cutting method based on the branch and bound method comprises three parts of image cutting trigger, off-line processing and the branch and bound method. The automatic image cutting method aims at solving the problem of manual intervention, positioning of the method is an auxiliary algorithm, and the method is generally started along with a positioning algorithm in practical application. In addition, the method not only can determine which priori map should be used by current positioning, but also can solve the problem of repositioning.

Description

technical field [0001] The present invention relates to the technical field of robot autonomous navigation, and more specifically, relates to an automatic graph cutting method based on a branch and bound method. Background technique [0002] In modern unmanned vehicles, positioning is an essential technical part. To achieve automatic driving, or automatic navigation, unmanned vehicles need to obtain accurate positioning in order to be able to navigate accurately. Just like when a person walks, he must know his position and direction before he can know where he is going. There are many kinds of existing positioning technologies, including single-point GPS positioning, differential GPS positioning, laser radar positioning, and computer vision positioning. [0003] Each positioning technology has its own advantages and disadvantages. For example, single-point GPS relies on the number of satellites to measure the quality of positioning; differential GPS requires two stations t...
