Problems solved by technology

[0005] In the further optimization process, the problem of column stripes existing in two-point correction is improved. Multi-point correction can solve the problem of column stripes that do not completely appear in two-point correction, but it needs to store (n+1)*i max *j max Data memory, where n is the number of temperature intervals, i max , j max The number of rows and columns of pixels requires the FPGA to store more parameters and takes up a lot of FPGA memory. This method inevitably increases power consumption

Abstract

The invention relates to the technical field of infrared image processing, and provides an infrared image processing method, device and system and a computer readable storage medium. According to theinvention, column stripe correction is carried out based on the column mean value data of black body data, i.e., according to the gray value of an infrared image, the column mean value data of a blackbody data is used to determine the temperature of column stripes to obtain column stripes; and column stripes are removed from the infrared image output by the non-uniform correction, and the infrared image corrected by the column stripes is output. Based on fusion correction combining multiple sections of two points and column stripe correction of different temperature intervals, compared with existing multi-point correction, the number of data points is small, the operation complexity and correction accuracy are reduced, a DDR read-write function does not need to be added, the memory and complexity are reduced, and the correction precision and accuracy can be further improved.

Description

technical field [0001] The present invention relates to the technical field of infrared image processing, in particular to correction of infrared images based on FPGA memory optimization, and in particular to an infrared image processing method, device, system and computer-readable storage medium. Background technique [0002] Infrared thermal imaging technology has effectively broadened the range of human vision and has been widely used in both military and civilian fields. Infrared thermal imaging uses photoelectric technology to detect infrared specific band signals of thermal radiation of objects, and converts the signals into images and graphics that can be distinguished by human vision. [0003] In the infrared thermal imaging detection system, the radiation is detected mainly through the detector and the signal is processed through the back-end processing circuit to convert the thermal radiation signal into the temperature / temperature field distribution to form visual...
