The invention relates to a method and a system for filtering small heat source interference of an infrared detector. The method comprises the steps of: grading the energy of a detected object, judginga grade triggering event according to a waveform appearing in a sensor, and carrying out the screening and filtering of the small heat source interference according to different grade triggering events; and obtaining a temperature compensation formula according to different air penetration capacities of a heat source at different environment temperatures and different energy of waveforms of the same heat source moving to penetrate through a lens to reach the sensor, obtaining a deviation compensation value to compensate the infrared sensor in the environment, and obtaining a compensated valuedelta Vpb. The method and the system have the advantages that the detection distance of the infrared detector can be increased, the small heat source interference resistance is enhanced, the sensitivity is improved, and the detection sensitivity at different temperatures can be kept consistent; and meanwhile, false alarms caused by interference of cold and hot air, strong light, temperature and the like are reduced, so that the infrared detector is energy-saving and reliable, and the problem of more false alarms of a common detector is fundamentally solved.
Description
technical field [0001] The invention relates to the technical field of infrared detection, in particular to a method and system for filtering out interference from small heat sources of infrared detectors. Background technique [0002] With the continuous advancement of industry technology, the application scope of detectors has gradually expanded to the civilian field, which has accelerated the development speed; at this stage, the research work of my country's detectors has developed from unit and linear array to infrared focal plane, and the products have developed from the first generation to the second generation. The fourth generation has led to the continuous progress of downstream related application technologies, the continuous expansion of product coverage, and the gradual formation of a relatively complete detector research and production system. The number of detector-related enterprises in my country is increasing, and the technological level of advanced enterpri...
