Reverse toll object identification method, device and system

Abstract

The invention provides a reverse toll object identification method, device and system. The method comprises a reverse toll object identification method and comprises the following steps that: when a toll object is identified in any one original frame image of video stream is monitored, labeling an identification area corresponding to each toll object to obtain the frame image; according to a preset algorithm and the frame image, determining a movement direction image corresponding to each identification area; in corresponding continuous N frames of movement direction images in the same identification area, according to the movement direction angle value of each pixel, selecting a movement target area; and when the movement target area in two adjacent frames of movement direction images meet a preset inverse toll condition, determining the toll object in the movement direction image as an inverse toll object. Therefore, the technical effects of the real-time monitoring and the automatic identification of reverse toll personnel, the reduction of human cost input and the reduction of safety protection hidden dangers brought by human factor interference are achieved.

Description

technical field [0001] The present invention relates to the technical field of security prevention and control, in particular to a method, device and system for identifying objects in reverse traffic. Background technique [0002] In high-security prevention and control areas such as airports, banks, transportation, prisons, military and storage warehouses, for safety needs, passers-by are generally required to pass in the predetermined direction, that is to say, no forward traffic in the same passage is allowed. There is also the case of reverse traffic. [0003] In the past, the identification and management of reverse traffic personnel mostly adopted manual preventive measures; this not only required a large amount of labor costs, but also increased the safety hazards caused by human interference, and often caused failures due to untimely warnings and countermeasures. greater security risk. [0004] At present, with the development of computer technology and image proce...
