Movement Behavior Pattern Recognition Method and System Based on Distributed Perimeter System

Abstract

The invention discloses a motion behavior pattern recognition method and system based on a distributed perimeter system. The method includes the following steps: collecting disturbance data of all detection points within the entire distributed perimeter detection range; Standardization operation, converted into a 0 / 1 matrix, if the disturbance data of a detection point is greater than the set threshold, the state of the detection point at the moment is recorded as 1, otherwise it is recorded as 0; all the coordinate information of 1 is extracted, Including time and position information, statistically calculate the response range S, response duration T and response shape M according to the coordinate information; use all the coordinate information of 1 to perform least square fitting, and calculate the slope K to obtain the speed of motion V, the eigenvector F (S, T, M, K, V) constituting the motion behavior mode; the motion behavior mode is determined by the eigenvector F.

Description

technical field [0001] The present invention relates to pattern recognition, in particular to a method and system for pattern recognition of motion behavior based on a distributed perimeter system. Background technique [0002] Perimeter security refers to important areas, such as national defense borders, military bases, key government departments, oil depots and coal fields, nuclear power plants, solar power plants, power plant substations, banks, prisons, museums, airports, ports, villa communities, data centers, water treatment Factories, chemical plants, schools and other major infrastructure, etc., in order to prevent illegal intrusion and sabotage activities, security precautions are formed along the perimeter of the site. The distributed perimeter system is a large-scale, high-sensitivity perimeter defense system, which has been paid more and more attention. However, the existing technology cannot judge the behavior of the movement, and cannot judge the direction of ...

Problems solved by technology

The distributed perimeter system is a large-scale, high-sensitivity perimeter defense system, which has been paid more and more attention. However, the existing technology cannot judge the behavior of the movement, and cannot judge the direction of movement and the behavior mode of the movement.

For example, patents CN102280006A, CN102168953A and Wu Mawei's "Research on Application of Distributed Fiber Fence Intrusion Monitoring Based on Phase-Sensitive Optical Time Domain Reflectometry Technology" mentioned the intrusion detection and positioning of the distributed perimeter system, but did not involve the identification of motion behavior The present invention proposes a method for identifying movement behavior patterns based on distributed perimeter systems, which solves the problem that the above-mentioned technologies cannot identify operation behavior patterns, and has the characteristics of high recognition rate, less false alarms, and high application value.
