In this papaer, a novel mobile robot obstacle avoidance method based on multi-sensor was proposed. According to the distant and near information of obstacles that detected by three front-end sonar sensors and four PSD sensors respectively, after analyzing the information data, obstacles distance and azimuth information were obtained, further, making strategy in the direction of motion and movement...
In this paper we introduce a novel method to detect and alarm pedestrian fall action in video surveillance by using frame difference method and pedestrians marker frame. Firstly, we used the fixed camera to capture video image information, and applied the morphological erosion and dilation method to reduce the noises. Then combined the frame difference method and the background difference method to...
The moving target detection is now a hot issue in the field of mobile robot. Firstly, the moving object data was received by using Omni-Vision and Laser Rangefinder sensors. Secondly, the data obtained from a single sensor was analyzed, and the moving target was discovered. Finally, the multi-sensor moving object data was effectively integrated by making use of information fusion method, So the moving...
