Embodiment 1

[0063] refer to figure 1 , in order to reasonably and effectively select monitoring preset points in the monitoring site, this embodiment provides a target positioning method based on the optimal layout of preset points in fixed-point video surveillance. Among them, when setting the monitoring preset point, the monitoring equipment is taken as the center of the circle, and the monitoring equipment is at the vertical inclination angle θ. n When monitoring the monitoring field, the farthest distance that can be monitored in the monitoring field is a circle drawn with a radius, and the circle drawn at this time is the monitoring circle in the monitoring field. At the same time, the farthest distance that the monitoring equipment can monitor in the monitoring site changes with the change of the vertical inclination of the monitoring equipment.

[0064] All the monitoring circles in the monitoring site are numbered in sequence, the outermost monitoring circle is the first monitori...

Abstract

The invention discloses a target positioning method based on optimal layout of preset points in fixed point video monitoring, and the method comprises the following steps: S1: determining a corresponding vertical inclination angle of monitoring equipment in a monitoring field in each monitoring circle; S2: acquiring a ground area corresponding to each monitoring circle field according to the vertical field angle and the horizontal field angle of the monitoring circle, and determining all monitoring preset points in each monitoring circle in the monitoring field; S3: numbering the vertical field angle, the horizontal field angle and the vertical inclination angle corresponding to each monitoring preset point, and storing the numbers in a preset point information base; and S4: determining the specific position of a monitoring target in the monitoring field through the preset point information base. The target positioning method based on optimal layout of preset points in fixed point video monitoring solves the problems that manual layout of preset points is complex and difficult when a fixed-point monitoring system is used for acquiring an image to be detected, determines the position of a target relative to a camera, improves the efficiency of manually checking the target after detection, and realizes closed-loop detection of fixed point video monitoring.

Description

technical field [0001] The invention relates to the technical field of target positioning, in particular to a target positioning method based on the optimal layout of preset points in fixed-point video surveillance. Background technique [0002] In today's society, land is a precious natural resource for human survival and development, and the sustainable use of land resources is the cornerstone of the sustainable development of human society. In today's expanding population, especially in my country, land is under enormous pressure, and the relationship between man and land is becoming increasingly tense, and a reasonable supervision system is increasingly required to supervise the status quo of land use. With the popularization of video surveillance equipment and the great improvement of video surveillance image processing technology in recent years, fixed-point video surveillance has become an important method for monitoring the status of illegal land occupation.
