Background interference elimination device and elimination method based on forest flash point de-disturbance point positioning device

Abstract

The invention relates to a background interference elimination device and an elimination method based on a forest flash point de-disturbance point positioning device, which relates to the field of forest fireproofing and aims to solve the problem that when the sun or a helicopter carrying out fire cruising and survey is recognized as a fire source by mistake to alarm, great interference is caused to the monitor system in use of the forest flash point de-disturbance point positioning device. The elimination device comprises a camera and a head, a data treatment front end and a ground control end, an alarm trigger module, a central processing control module, a position information resolving module, a data storage module, an alarm confirm module and an alarm cancel module. The elimination method comprises that: firstly receiving an alarm signal and starting the system to obtain the information of a fire position, and comparing with the stored information of terrain, then judging the truthfulness and counterfeit of the fire, and sending the alarm signal or canceling the alarm signal. The device and the method in the invention can be applied in accurate positioning of the forest flash point and judgment the truthfulness and counterfeit of the fire at the same time.

Description

technical field [0001] The invention relates to a background interference elimination device and elimination method based on a forest fire point de-disturbance single-point positioning device, and relates to the field of forest fire prevention. Background technique [0002] Forest is the main body of terrestrial ecology. It has high ecological and economic benefits and is a precious resource for human beings. However, forest resources have decreased sharply in recent years. In addition to deforestation, forest fires are the main reason for the reduction of forest area. . Therefore, the study of fire prevention measures in forest areas has been valued by various countries. [0003] At present, with the development of science and technology, many areas have begun to use the method of installing infrared cameras in deep forests to monitor forests. It is even proposed to process the camera graphics by image processing technology to realize the automatic monitoring of the cover...
