Abstract

The method belongs to the technical field of correction and provides a pixel distortion correction method, a pixel distortion correction device, a terminal and a computer readable storage medium. Thecorrection method comprises the following steps of: correcting; the method comprises the following steps: acquiring a plurality of frames of images of a measured target, respectively acquiring pixel values of pixel points corresponding to specified pixel positions on each frame of image to obtain a plurality of pixel values, determining reference pixel values of the plurality of pixel values, andperforming distortion correction on the pixel values of the pixel points corresponding to the specified pixel positions based on the reference pixel values. According to the invention, the accuracy ofthe measured pixel value of the pixel point corresponding to the specified pixel position of the multi-frame image of the measured target can be improved.

Description

technical field [0001] The invention belongs to the technical field of correction, and in particular relates to a correction method for pixel distortion, a correction device, a terminal and a computer-readable storage medium. Background technique [0002] Photothermal reflection temperature measurement technology is a non-contact temperature measurement technology, which uses the principle that the change rate of the reflected light intensity of the object irradiated by light in the photothermal reflection phenomenon changes with the temperature of the object. The change rate of the reflected light intensity of the object can realize the temperature measurement of the measured object. [0003] In order to achieve microscopic thermal imaging with high spatial resolution, a high-performance optical microscope is usually used to construct a microscopic light reflection thermal imaging device. The illumination system of the optical microscope is used to provide probe light to i...
