| Abstract: | In this paper, a non-contact measurement system based on the CCD Camera is designed.It completed the edge detection and completed the non-contact measurement for the ring by using of sub-pixel edge detection method.Then implemented the storage management and network transmission for the measurement data using the database.The experimental results show that: the error of measurement accuracy for the Outside diameter of the ring is 0.005mm, 0.001mm for Inside diameter, 0.015mm for the wall thickness, less than 0.02mm for the overall absolute error and less than 0.07% for the relative error, which can meet the engineering requirements of high accuracy. The system is suitable for hazardous industrial field environments, the data storage management functions is very convenient for practical applications. |
