摘　　要：为提高角度测量的精度、速度以及扩大角度测量方法的应用领域,提出一种采用基于计算机视觉的图像测量技术进行角度测量的方法。通过对采集到的被测工件图像进行边缘检测、细化处理和霍夫变换,从而确定出其角度。实验结果表明,角度的图像测量法在测量精度、速度、抗噪声等方面具有很大的优势。In order to improve the precision and the speed of angle measurement and widen the applied fields of the measur- ing method, an angle measuring method that adopts the image measuring technology based on computer vision is introduced. An angle value is obtained when the measured work piece image is processed by edge detection, thinning and Hough transformation. The experimental results indicate that the method has many advantages in the measuring precision, speed and anti-noise.
