| 摘 要： | 在结构光视觉检测系统中,光条中心的提取精度直接影响到整个测量系统的测量精度.光条图像的处理是其中重要的一步,尤其是受到严重噪声干扰的图像.探讨了被多种噪声干扰的光条图像的处理和精确提取光条中心的方法.给出了一种消除环境干扰的滤波模板并实验验证了其滤波效果.使用这些光条图像处理方法使整个测量系统在200mm×200mm的测量范围内测量精度达到0.083mm.

| Abstract: | In a structured-light vision system, the accuracy of center position of the stripe is of great importance for that of the whole measuring system. Processing the image of stripe is an important step, especially for images with serious noises. Methods for processing images of stripe disturbed by various noise sources were discussed, as well as the method for detecting accurately the center of stripes. A special filtering mask was submitted for "surrounding" disturbance and was verified effective. For the measuring range as large as 200mm×200mm the accuracy of the whole measuring system when using the methods mentioned is 0.083?mm. |
