Abstract

The invention is suitable for the technical field of image processing, and provides a thermal imaging correction method and device and terminal equipment. According to the embodiment of the invention, when the environment temperature changes, a blocking piece is controlled to cover a detector, and a first gray value of the blocking piece is obtained; non-uniformity correction is carried out on the first gray value of the separation blade to obtain a second gray value of the separation blade; the separation blade is controlled to reset, and the gray value of the thermal imaging target is obtained; two-point correction is carried out according to the gray value of the thermal imaging target, the second gray value of the separation blade and the two-point correction parameter, a corrected gray value is obtained, the response rates of different detection units can be corrected to be the same, the non-uniformity of the image is eliminated, the corrected gray value can be suitable for all temperature intervals in the temperature measurement range, and therefore, the imaging stability is improved.

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...
