Abstract

Abstract In recent years, 3D profile measurement has been widely used in the high-precision manufacturing industry. However, the unavoidable salt and pepper noise will greatly reduce the accuracy of the measurement system. To measure the surface profile with variable curvature more accurately, a 3D measurement system is built based on fringe projection technology and Spearman Correlation Analysis. Experimental results show that the error caused by pepper and salt noise is low and the system performance is good.
