Now  based on binocular parallax of human eyes  we advance a method used to get the distance by measuring the offset on image panel. On this foundation  we also analyze the error in forward. The academic analysis indicate that the measurement would be impacted severely by transverse offset and angle-measuring offset  in contrast  much slightly by lengthways offset. When we put this facility into practice  this facility can suffice practical demand completely if we select the space between bi-camera and the focus of facility rationally.

The former is direct measurement so the results are more accurate but the test is costly and complicated  so that it is limited in the application. Theoretical and simulation calculation are widely used in the target IR radiation calibration. Here we give the basic configuration of the calibration platform for measuring the IR radiation of the large area low temperature blackbody source  and discuss the calibration flowchart and key technologies for atmospheric transmission correction. The dynamic data are analyzed in real time to determine the IR radiation features in the data fusion subsystem  and the experimental results show that the calibration method is feasible and practical. 2010 IEEE.
