中文摘要: |
为了实现精密零件尺寸在线检测的智能化与高精度,课题组设计了一种基于机器视觉的尺寸检测系统。该系统利用OpenCV实现算法设计,基于Canny边缘检测,结合Zernike矩实现亚像素边缘提取,利用最小二乘法实现圆心拟合。在QT平台上,基于OpenCV结合C++完成测量系统的界面开发。检测结果表明:该测量系统精度能达到0.01 mm,能够满足当前项目需求。该测量系统具有一定的工程实用性。 |
英文摘要: |
In order to realize the intelligentization and high precision of the on line dimension detection of precision parts, a dimension detection system based on machine vision was designed. The center of the circle fitting was realized by using OpenCV algorithm based on Canny edge detection, combining with the Zernike moment subpixel edge detection and using the least squares method. On the QT platform, the interface development of the measuring system was completed based on OpenCV combined with C++ . The test results show that the accuracy of the measuring system can reach 0.01 mm, which can meet the requirements of the current project. The measuring system has certain engineering practicability. |
