面向重建的结构光中心快速提取方法
Reconstruction Based on Real-Time Extracting Light Strip Center Method
摘要
Abstract
In the non-contact optical measurement system in reverse engineering, physical surface data accurate and rapid extraction laser stripe is a key factor to guarantee system precision and real-time of algorithms. The paper based on the laser intensity distribution conforms to the Gaussian distribution and the continuity border of laser stripe, improved the traditional laser stripe center extraction method, combined with the shape and distribution of the light in the image, Through scanning laser stripe center from a different position and orientation of the image and compare the times of different scanning method. Apply this method to rebuilding three-dimensional contour of the train hubcaps. Experimental results show that the method is significantly improved than the traditional method. This method has a strong practical.关键词
