摘要
规则的一组栅线在物体表面的投影将发生畸变,这畸变的栅线投影图象中包含着被测物体表面深度的信息。结合计算机图象处理技术,本文提出了运用于该测量原理中的系统自我标定方法,使测量系统自动适应不同的量程、精度及不同的测量环境的三维形状自动测量。文中论述了该测量方法的计算机图象处理过程,给出了测量实例,并提出了进一步设想。
A group of parallel grating lines will be distorted when they are project- ed onto the surface of a 3-D object.The information of surface height of the object is included in the images of distorted grating lines.In this paper,computer-aid image pro- cessing technique is described for measuring shapes automatically to various accuracies, ranges and circumstances.An example is given and further improvement is proposed.
