Problems solved by technology

Non-uniformity correction (NUC for short) is a commonly used correction method at present. When using this method to correct infrared images, it is necessary to collect the background data of all temperatures of the infrared sensor in a certain temperature range. Large amount, time-consuming, and slow correction of infrared images

Abstract

The invention discloses an infrared image correction method. The method comprises the steps: acquiring the current temperature of an infrared sensor; judging whether the current temperature is one ofa plurality of pre-selected temperatures or not; if the current temperature is the pre-selected temperature, collecting and storing background data; and determining a difference value of the background data of the adjacent pre-selected temperatures, and correcting the infrared image according to the difference value. Only the background data at the pre-selected temperature needs to be collected and stored, so that the collection workload is reduced, time is saved, and the correction speed of the infrared image is increased. In addition, the invention further provides a device, electronic equipment and a computer readable storage medium with the advantages.

Description

technical field [0001] The present application relates to the technical field of infrared sensor calibration, and in particular to an infrared image calibration method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] The irregular stripes in the infrared image are the embodiment of the non-uniformity of the infrared sensor. The reasons for the non-uniformity are very complicated. It is unrealistic to completely eliminate the non-uniformity during production. Only by non-uniformity correction can the infrared image be improved. quality. Non-uniformity correction (NUC for short) is a commonly used correction method at present. When using this method to correct infrared images, it is necessary to collect the background data of all temperatures of the infrared sensor in a certain temperature range. The amount is large, it takes a long time, and the correction speed of the infrared image is slow. Therefore, how to improve the in...
