Calibration of Three CCD Camera Overhead Contact Line Measuring System
Applying three-dimensional photographic measurement method and using three CCD finer image camera to compose the railway overhead contact system geometric parameter measuring equipment, in order to solve the issue of the pixei coordinates being converted to the slope of a straight line in 3-D space, it proposed equidistant sampfing grid calibration method. In this method, only single sample is taken, and through the pulse-position auto-identification and curve fitting, it can build the corresponding relationship between each CCD pixel coordinates and the line of the CCD imaging lens projection center. With high accuracy, the calibration process is fully automated.
