摘要
光斑的边缘检测算子对一幅激光光斑的质量有着重要的影响,是激光光斑的后续图像处理和分析的前提。目前,在国内外应用比较广泛的边缘检测算子主要有Roberts算子、Prewitt算子、Sobel算子、Gaussion-Laplace算子和Canny算子。本文在总结几种典型边缘检测算子的基础上,对比分析了各个算子的优点和不足,对未来算子的改进方向做出展望。
The edge detection operator of the spot has an important influence on the quality of a laser spot,and is the premise of subsequent image processing and analysis of the laser spot.At present,the most widely used edge detection operators at home and abroad are Roberts operator,Prewitt operator,Sobel operator,Gaussion-Laplace operator and Canny operator.On the basis of summarizing several typical edge detection operators,this paper compared and analyzed the advantaged and disadvantaged of each operator,and forecast the improvement direction of future operators.
