Infrared detector blind pixel detection system and method

Abstract

The invention relates to an infrared detector blind pixel detection system and method. The method comprises the following steps: S1) carrying out infrared detection to generate infrared detection data; S2) collecting the infrared detection data according to the set time interval, and generating a detection image correspondingly according to the collected infrared detection data; S3) carrying out singularity detection on each pixel in the detection image, and recording the singularity appearing probability of each pixel to a singularity probability table; and S4) taking the pixels, the singularity appearing probability of which is higher than or equal to the set value in the singularity probability table, as blind pixels, and carrying out blind pixel compensation. Compared with the on-site repair and user-calibrated modes, the method is high in efficiency and detection precision, and not easy to cause error judgment.

Description

technical field [0001] The invention relates to the technical field of infrared detectors, in particular to an infrared detector blind element detection system and method. Background technique [0002] The imaging of the infrared detector is composed of many pixels. Some pixels (blind pixels) will fail during use, resulting in the failure of normal imaging and affecting observation. Blind pixel detection is generally carried out during the product production process and requires a professional personnel operation. If there is a blind element during use, in order to prevent misuse, it is often necessary to send the product back, or even on-site maintenance; or open the blind element function to customers; or detect the blind element in real time; but the cost of product return or on-site service is high and the efficiency is high. Low; open the function of blind element to customers, and customers may misuse it; real-time detection of blind element is not very applicable, an...

If there is a blind element during use, in order to prevent misuse, it is often necessary to send the product back, or even on-site maintenance; or open the blind element function to customers; or detect the blind element in real time; but the cost of product return or on-site service is high and the efficiency is high. Low; open the function of blind element to customers, and customers may misuse it; real-time detection of blind element is not very applicable, and it is easy to misjudge the detection target, so it is necessary to solve these problems
