The invention discloses an embedded-type network camera with passenger flow counting function and a passenger flow counting method. The camera comprises an image collection module, a passenger counting module and a communication module. The method comprises the following steps: the image collection module collects site image video data in real time and transmits the video data to the passenger flow counting module; the passenger flow counting module models the background of the received image video data, divides a motion region by a frame differential method, extracts the passenger number information by further using a passenger number template matching algorithm, tracks the motion in the passenger number region and counts if the passenger number region exceeds a preset virtual door. By implanting the complex passenger flow counting function in the front-end camera, the invention reduces the load of a server, improves the processing instantaneity and the reaction speed of a monitoring system, reduces the deployment of an external intelligent processing server and reduces the investment cost.
Description
technical field [0001] The invention belongs to the field of video monitoring, and relates to a network camera and a passenger flow counting method, in particular to an embedded network camera with a passenger flow counting function and a passenger flow counting method. Background technique [0002] With the popularization of the Internet and the rapid development of computers, IP networks, image processing, and transmission technologies, video surveillance technology has also made great progress. The traditional video surveillance system that requires dedicated personnel is increasingly unable to meet the increasing requirements of today's society for surveillance systems. Digitization, networking and intelligence are the development direction of monitoring system. [0003] Network cameras are a new generation of network cameras produced by combining traditional cameras and network technologies. Based on the TCP / IP protocol, images and control information are transmitted t...
