| description | The invention provides a short-wave infrared binocular detector non-uniformity correction method and system for intelligent sorting. The short-wave infrared binocular detector non-uniformity correction method comprises the following steps: S1, collecting short-wave infrared irradiance response data and integrating sphere standard irradiance data; s2, determining non-uniformity correction parameters of the binocular detector according to the data in the step S1; s3, performing real-time non-uniformity correction by adopting an FPGA non-uniformity correction circuit according to the non-uniformity correction parameters in the step S2; s4, judging the consistency of the binocular detector according to negative feedback of the system, calculating a consistency correction parameter, and comparing the consistency of the corrected data through correlation analysis such as standard deviation; and S5, according to the consistency correction parameter, performing real-time correction by using an FPGA correction circuit |
