摘要
文章在一套基于计算机图像处理和识别的水平尺标定系统的基础上,比较了几种不同的轮廓提取算法,重点阐述了采用最优阈值变换并结合轮廓跟踪的方法对水平尺气泡轮廓的精确检测。试验结果表明,该方法有效地降低了图像的噪声,改进了检测结果,达到了高精度标定的目的。
Based on a measuring system using digital image processing and recognition,several algorithms of contour extracting are analyzed and compared.With the combination of optimal thresholding and contour tracking,the air bubble image taken by CCD camera is examined.As a result,the balancing result for calibration is improved and the noise of the image is reduced.
