Step 5.5: the parallel processing capability based on FPGA respectively carries out each characteristic area of the blending image non-simultaneously
Uniformity correction;For each characteristic area, the main control chip calculates the mean temperature of each point in the characteristic area first,
Then according to the mean temperature, corresponding correction parameter is read from the RAM in the FPGA, and is completed according to the following formula
Nonuniformity correction
WhereinThe image that infrared detector exports under the conditions of expression Uniform Irradiation degree;
Step 5.6: the blending image after correction compensates boundary gray value using mean filter method.
