线形激光图像中光迹的细化是视觉测量的关键问题。由于激光成像过程中存在散斑噪声,导致图像中的光迹断裂,光迹粗糙,影响光迹细化的准确性和速度。针对上述问题,提出基于预测与跟踪的光迹快速细化方法。首先对激光图像进行预处理以简化计算和抑制散斑噪声,接着对光迹进行搜索与标记,然后运用基于预测与跟踪的方法快速定位光迹的中心线,完成光迹的细化。实验结果表明,该法能准确实现光迹细化,单幅图像的细化速度小于10 ms。

The thinning processing of light trails for the linear laser image is the key to the visual measurement prob -lem.With speckle noise ,in the process of imaging ,light trails of the image become fractured and rough , thus af-fecting not only the accuracy but also the speed of the refinement of the trails .According to the above problem , this paper proposes the method based on prediction and tracking to fulfill the refinement .Firstly, preprocessing the la-ser image to simplify the calculation and suppress the speckle noise , then searching and marking the trails ,and last-ly, using the method ...
