This patent includes: extracting two adjacent images with a set time interval from the collected video to be recognized, and extracting the optical flow diagram from the two images; Fusing the characteristic data of the optical flow diagram with the characteristic data of the previous frame image; Based on the fused feature data, the violence classifier is identified. According to the technical scheme provided by the patent, this method can improve the accuracy of violent sorting and identification, and then improve logistics services.
With the development of Internet technology, online shopping has become more and more popular. Behind online shopping is the development of logistics industry, so more and more people begin to choose express delivery. In the process of transporting goods by courier companies, courier companies need to sort the transported goods to ensure that the goods entering the same route are put together. However, when there are many courier items, the staff of the courier company may throw the courier items and products in the process of sorting in order to improve the sorting speed. In order to reduce the phenomenon of violent decomposition, SF disclosed the patent of violent sorting and identification system.
The existing violence identification methods are: after receiving the video to be identified, obtaining the video frame; Firstly, identify the limb areas that produce violent sorting in video frames, such as throwing express body organs, such as arms or legs; Then further identify the staff who have violent sorting behavior according to the marked limb areas in the video frame. However, if there is an error in identifying the limb area that produces violence classification in the video frame, it will directly lead to an error in the result of violence classification recognition, so the accuracy of this violence recognition technology for violence classification recognition is still relatively low. Due to the low accuracy of the existing violence classification and identification technology, this patent of violence classification and identification system published by SF Express proposes a violence classification and identification method, device, equipment and storage medium, which can effectively improve the accuracy of violence risk identification.
Because more and more people are keen on online shopping, this is a great pressure for the express delivery industry. When too many goods are transported, violent sorting is inevitable. SF Company's patented technology of violence sorting and identification can effectively improve the accuracy of violence risk identification. Through these technologies, we can identify the staff who carry out violent sorting, thus reducing violent sorting behavior and improving the quality of logistics service.
