The Portable Unit for the Online Measurement and Fitting of Large Curved Surface

Abstract:

Measurement of curved surface having large radius of curvature is still a problem for the modern industry measurement. The method of measurement based on laser range finder is a method commonly used in modern industry measurement, which can solve this problem. The system has larger measurement range and higher precision, it belongs to the non-contact measurement systems, so the measured piece could be freely set. Establish an appropriate measurement system based on surface features; obtain the spatial coordinate of the detection points of the measured curved surface through laser ranging; acquire the three-dimensional diagram of the surface features of the curved surface with matlab-based curved surface fitting software; automate the detecting system via the singlechip-based automatic control system. The present device had advantages of high accuracy, convenience and shortcut, low cost and strong adaptability to environmental conditions, which can effectively compensate for the present vacant situation of the portable large curved surface measuring device and have wide applications.
