The invention provides a video-based one-way passenger flow information detection method in a two-way passenger flow channel. The method comprises the following steps: acquiring a video image in a bidirectional passenger flow channel scene, and performing passenger flow target detection on the video image by using a target detection algorithm; and performing target tracking on a passenger flow target in the video image by using an improved DeepSort algorithm to obtain one-way passenger flow statistical information in the two-way passenger flow channel. According to the method, the target tracking effect under the shielding condition can be effectively improved, and accurate passenger flow volume statistics can be carried out in a certain direction in bidirectional passenger flow videos such as subway scenes and the like. Meanwhile, the running speed is increased, and the real-time performance of passenger flow information detection is ensured.
Description
technical field [0001] The invention relates to the technical field of passenger flow information detection, in particular to a method for detecting one-way passenger flow information in a video-based two-way passenger flow channel. Background technique [0002] As an important node in urban rail transit, subway stations are of great significance to the operation safety and transportation efficiency of the entire subway network. Large passenger flow has become the norm in urban rail transit. Accurately grasping the status of inbound passenger flow is the basis for scientific passenger flow control. At present, video surveillance technology has been widely used in subway scenes. However, due to various factors of on-site engineering, the video of passenger flow in subway passages, especially the video of passenger flow in transfer passages, often includes two-way passenger flow. [0003] At present, most of the one-way passenger flow information detection methods based on su...
