Paper Abstract

At present non-contact photonic systems based on laser profiling are applied in industry and transportation. Often they have restrictions in overall dimensions. These restrictions result in the captured image will have the distortions. Linear distortions caused by rotation of camera relative to object are excluded by Eller's transformations. Non-linear distortions caused by small distance between camera and object and optic aberrations may be decreased by calibration. To provide required accuracy it is necessary to find correspondence between image and real coordinates using optical calibration. Original method and equipment for the measuring system calibration have been developed. Dependence between image and real coordinates may be approximated by polynomial function. Special equipment includes the precision mechanical array allowing to place needed vertical and horizontal rail coordinates, platform for camera and laser mounting, test monitor and computer to calibrate was developed.
