Abstract

A system for measuring rough surface accuracy was designed. A line edge laser trianglulation method was used to realize subpixed measurement and a threshold value method was utilized to improved measuring image algorithms. At the same time

a morphological filtering was used to process the surface image of a quizzee. The results show that the system can improve the accuracy better and obtain the satisfied image ledge and the accuracy survey of 5 m.The measurement system can be used in a wide scope and can also realize the measurement of the thickness and uniformity of coating layer on battery electrodes with rough surface.
