[Abstract]:The collection of logistics data is the basis of realizing supply chain logistics informatization. In this paper, the method of image processing is used to collect the material flow data, and the pedestrian is regarded as the moving object of image research. Based on the technology of moving target detection, classification and tracking, and combined with the extensive application of target statistics in public places such as stations, roads, supermarket entrances and exits, an image based logistics data acquisition system is designed and implemented. In the aspect of moving target detection, the background modeling method is used to update the background of the monitored region in real time, and the method of background subtraction and inter-frame difference is used to detect the motion, and the moving region is extracted. In the aspect of moving object classification, this paper adopts a simplified target classification method, selects the aspect ratio of moving area and vertical projection histogram gradient as the feature to classify the target, and extracts the travel target. As the basis of follow-up tracking statistics. In the research of line human tracking, the Camshift algorithm is used to complete the tracking task by introducing Kalman prediction and Camshift matching search algorithm, aiming at the defects of the Camshift algorithm which is prone to the tracking loss when the targets are occluded from each other. Finally, on the basis of the previous research, this paper aims at the application demand of the logistics data acquisition system, and realizes the detection, extraction and tracking counting of the human body target in the actual environment. The experimental results show that the method is practical and the statistical data have a high accuracy.
