Abstract

The present application is applicable to the technical field of image processing, and provides a thermal imaging correction method, device and terminal equipment. In the embodiment of the present application, when the ambient temperature changes, the shutter is controlled to cover the detector and the first gray value of the shutter is obtained; the first gray value of the shutter is corrected for non-uniformity to obtain the The second gray value of the shutter; control the reset of the shutter to obtain the gray value of the thermal imaging target; according to the gray value of the thermal imaging target, the second gray value of the shutter and two points The correction parameters are corrected at two points to obtain the corrected gray value, which can correct the responsivity of different detection units to the same and eliminate the non-uniformity of the image, and make the corrected gray value applicable to each temperature range within the temperature measurement range, thereby Improve imaging stability.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a thermal imaging correction method, device and terminal equipment. Background technique [0002] With the continuous development of infrared sensing technology, the accuracy of temperature detection and imaging clarity of thermal imaging equipment has been greatly improved, and it has been widely used in various fields such as fire protection, medical treatment, and security. [0003] Thermal imaging equipment is very sensitive to changes in ambient temperature. When the ambient temperature is too low relative to the temperature of the thermal imaging target, the grayscale value will be oversaturated and the image will become white. When the ambient temperature is too high relative to the temperature of the thermal imaging target, the grayscale value will If the value is too low, the brightness of the image will be too dark, which will cause the te...
