A high temperature interference source removal method based on thermal imaging

Abstract

A high-temperature interference source removing method based on thermal imaging includes a) a thermal imaging device scans the monitoring area to form a panoramic image of the monitoring area; b) thedetection threshold value is Z1 is calculated; c) in the real-time operation of the thermal imaging equipment, a target which is larger than the detection threshold value Z1 in the image is acquired and identified, and the target which is larger than the detection threshold value Z1 is determined as an effective high-temperature alarm target. The detection threshold value Z1 is calculated in an actual monitoring region at first, and then the target which is larger than the detection threshold value Z1 is acquired and identified in subsequent thermal imaging monitoring, and an alarm is given tothe effective high-temperature target of the branch. The other high-temperature targets can be used as an interference source to be shielded, so that the situation that the effective information is covered due to the temperature sensitivity is effectively avoided, and the situation of false alarm or missing is avoided.

Description

Technical field [0001] The invention relates to the technical field of thermal imaging, in particular to a method for removing high-temperature interference sources based on thermal imaging. Background technique [0002] Thermal imaging is more and more widely used in various fields. Its characteristics based on temperature imaging have unique advantages in fire protection monitoring, power inspection, security monitoring and other industries; but if there are high-temperature interference sources in the visible area, because Its temperature sensitivity causes effective information to be covered up, causing false or under-reporting situations. [0003] The existing methods for removing or shielding high-temperature interference sources mostly focus on manual area shielding, fixed target shielding, shielding based on temperature ranges, and shielding based on pan-tilt angles. It is impossible to achieve intelligent, automatic, and automatic control of high-temperature interference s...
