For a wide range of detection and tracking of target for a mobile service robot problem under the unknown environment, this article puts forward a method based on the heterogeneous information fusion structure to realize the target detection and tracking in real-time of robots, whose basis is distributed intelligent network devices and the robot’s 2D laser range finder in the intelligence space. The system matches the moving target by the information on color, and carries out the 3D reconstruction of the target depending on the triangulation technique and least square method. The moment it detects the moving target, in order to get the exact distance information, it will scan the target human’s leg by the laser range finder to cluster the nearest neighbor. Meanwhile, this article raises a better Iterative Extend Kalman Filter for the heterogeneous sensor information fusion to realize the simultaneous robot localization and target tracking based on the intelligence space. The experimental results verify the effectiveness of the proposed method.
