结构光测量中强噪声干扰条纹图像的处理

Process Image of Strip with Serious Noises in Structure-light Measuring Technique

提出了一种应用于结构光测量系统中的强噪声干扰条纹图像处理过程,包括通过平滑滤波、差影法和阈值法结合进行二值化,以及图像的测量技术,对条纹图像降噪并快速分割,再对图像细化,提取特征数据.实验表明,该过程能在不使用其他专业软件的情况下,快速而准确地从强噪声干扰的条纹图像中得到图像特征数据.

This paper presents a kind of method that procesces image of strip with serious noises in structure - light measuring technique. Including low the noises of image and rapid segment by the smooth and filter of image, image algebra operation and threshold segmentation were combined together to binary -coding, and image measuring technique. Then the image was thinned and data was extracted from image. The experiment expreses that this method can extracting data from image of strip with serious noises rapidly and accuracy without other professional software.
