Research and Realization of Auto-Calibration Technique Based On Stereovision
Purpose -The purpose of this paper is to analyze present-day state on calibration technique and to realize the auto-calibration technique based on projected grating 3D measuring system.Design/methodology/approach -Auto-calibration technique which was named as multiple target tracking for detecting outline based on random placing and regular number was put forward. The practical arithmetic was also presented at the same time.Findings -According to the arithmetic mentioned above, the relevant experimental result was gained.Furthermore, the precision of calculation result was analyzed. The results showed that the operation was simplified, the orientation precision of image outline edge was ensured and calibration precision was kept within 0.02~0.05mm by using the arithmetic in this work.Practical implications -The research verified the feasibility of auto-calibration, providing arithmetic that is extremely useful for the industrial application of computer vision technologies.Originality/value -The paper deals with experimental work on innovative techniques on which data are still lacking in literature. In particular, an original auto-calibration technique which is named as multiple target tracking for detecting outline based on random placing and regular number is provided.
