提出了一种基于快速响应动态聚焦透镜的微零件装配智能视觉系统。该系统仅使用一个图像传感器就实现了对微小零件的大景深实时观察和三维形貌测量。在本文中，我们报告了一个新开发的实时算法称为一个像素的方法，用于生成一个清晰的图像具有深景深。这种方法是能够处理一个原始图片（640/spl倍/480像素每帧）在大约1.0 ms。我们还报告了使用亮度对比度方法的高精度三维形状测量的结果。
We propose a new smart vision system using a quick-response dynamic focusing lens suitable for micro parts assembling. This system realizes real-time observation for micro parts with a deep depth of field, as well as three-dimensional shape measurement using only one image sensor. In this paper, we report a newly developed real-time algorithm called the one pixel method for generating a clear image having a deep depth of field. This method is able to process one original picture (640/spl times/480 pixels per frame) in approximately 1.0 ms. We also report the results of three-dimensional shape measurement with high accuracy using the contrast of brightness method.
