摘要
Aiming at the problem that traditional methods cannot meet the problem of synchronous positioning of multi -mobile robots in different motion states, a synchronous positioning method of multi -mobile robots based on visual simultaneous localization and mapping (SLAM) algorithm is proposed. Analyze the general model of SLAM problem, realize visual SLAM feature detection through scale invariant feature transform algorithm, and match image features based on active vision. A multi -mobile robot motion state estimation model is constructed, an octree model is used to construct a multi -robot synchronous localization map, and the camera pose tracking is realized by using the oriented fast accelerated segment test and rotated binary robust independent elementary features points that are not in the target bounding box. The three-dimensional points in the environment recovered by visual SLAM separate the background target and the moving target, and match the corresponding target in the previous frame through the feature to realize the synchronous positioning of the multi -mobile robot. The experimental results show that the method can realize the synchronous positioning of multi -robots under the state of multi -robot linear motion, curvilinear motion and mixed motion, and the positioning accuracy is high.
