Statistical study of accuracy of the video-positioning system for GPR

Abstract

Here we present results of the statistical study of the accuracy of the local optical positioning system for the industrial GPR OKO-2. The results of measurement are forming a statistical set. The statistical set should verify the accuracy LPS. The proposed LPS uses special tapes with a special periodic pattern as a reference object. The video camera records the image of the marker tapes, was located on a fast mechanical scanner. The scanner produced an accurate movement of the camera perpendicular to the tape. During the moving process, LPS measures the distance between the camera and tape and compared it with the scanner data.
