Geometric Dimensional Measurement of Shearer Rotational Parts

A geometric dimensional measurement system for form and position error detection of shearer rotational parts is developed in this paper with the error evaluation principle based on the minimum zone method. The system is characterized by using the charge coupled device (CCD) image sensor to capture image signals, and then using image processing techniques to extract useful signals from the image data signal. By focusing on image processing technology and error separation technology, the system can reduce the previous dependence on the baseline data collection, improve the accuracy and robustness of data collection, and simplify data collection platform.
