Optical boundary discrimination in spatial posture measurement

摘要

The measurement of the spatial attitude of the tube sheet is the basis for automated shield assembly. This paper presents an image processing method for measuring the surface grooves of the tube sheet. The measurement process consists of two processes: target detection and target coordinate measurement. The environmental factors that affect the recognition rate are analyzed and effective recognition coefficients are defined to further improve the method's ability to resist interference from external factors.
