【摘要】 传统的激光束宽测量方法多采用光学仪器和衍射、干涉等方法,在精度和速度上都存在特定约束,而鲜有采用图像处理的方法对激光束宽检测。通过激光束积分模型获得相应的激光束宽度获取方法,并采用Sobel边缘提取高斯滤波获激光束光强特征分布函数,再由Hough拟合圆积分区间计算出激光束宽在x轴和y轴上的像素宽度。测试结果表明,这种结合了机器视觉的图像处理算法对激光束宽测量的数据实用可靠,测量效果相比于传统测量方法具有直观性和便捷性。更多还原

【Abstract】 Traditional laser beam width measurement methods usually adopt optical instruments with diffraction,interference and other methods,which are specific constraints in accuracy and speed.In contrast,there are rarely using image processing methods.The laser beam width acquisition method is obtained by laser beam integration model.The intensity distribution function of laser is obtained by Sobel operator and Gaussian filter,and the pixel width is calculated on the x-axis and y-axis by Hough fitting circle integration area.The experimental results show that the image processing algorithm is practical and reliable for measurement of laser beam width,and the measurement effect is intuitive and convenient compared with the traditional measurement methods.更多还原
