基于图像边缘与Hough变换的振动位移测量方法
Vibration Displacement Measurement Method Based on Image Edge and Hough Transform
摘要
Abstract
In order to solve the problem of vibration displacement measurement being limited by the installation space of sensors,and reduce the impact of sensor quality on measurement accuracy,a vibration measurement method based on video image was proposed,and the relation between image edge detection results and target object displacement was established.Due to the presence of discontinuity or falsehood in image edges by using the classic Canny algorithm for image measurement,a method of combining image gray level and Hough transform was adopted to improve the measurement accuracy.In order to verify the effectiveness of this method,a vibration experiment based on a vibration test bench box was designed.And the results obtained from the classic Canny algorithm and video image measurement results proposed in the article were compared with the results measured by sensors.The experimental results show that the proposed method improves the accuracy of image measurement by approximately 12% compared to using the classic Canny algorithm.The proposed method has the advantages of simple measurement and flexible measurement range,and provides a new way to measure the site with limited environment.关键词
