A Non-Contact Method to Measure the Spatial Axis Position for Large-Scale Holes

Abstract:

Based on laser triangulation measuring principle, a non-contact precise measurement method is proposed to get the spatial axis position of the large hole parts. According to the method, the measurement system is designed and the measuring mathematical model is founded. The fitting curve of the scanning profile and the space equation of the central line are obtained by least squares method. Besides, the errors of the measurement system are analyzed and corrected. The spatial position of the central axis could be quickly obtained by the method.
