A Study of Automatic Calibration in Dual Linear-CCD Camera Intersection Measuring System
CCD intersection measuring is an untouched technique that used to measure the coordinates of aerial moving targets,which has been widely applied in optimal test.At present,the main problem is to improve the measuring precision,and much research has been made in system structure parameter optimization,error analysis,intersection principle improving and so on.But when using the measuring system,users are always required to be clear about the working elements of the system,which restricts its usage.In addition,the instruments are disposed and many inputs must be measured manually.As a result,precision improving becomes a difficult work.After finding out the mathematic corresponding relationship between input and output variables of measuring system based on intersection measuring principle,the paper comes up with an automatic calibration algorithm wrapping up the technical details,which makes the complicated principle transparent to users.The setup and parameter adjustment of measuring system with much less manual work has been simplified and deep advancement in precision improving becomes possible.
