摘要
针对当前激光光斑中心检测定位方法中,普遍存在着定位完成时间过长、检测准确度较低、定位费用消耗较高等问题。提出一种基于圆心拟合算法的激光光斑中心检测定位方法。通过对激光光斑进行分析,采用中值滤波对图像进行去噪处理,将处理后的图像采用自适应阈值法对其进行激光光斑中心分割及特征提取,利用Sobel算子对激光图像光斑中心进行检测,采用圆心拟合算法对中心进行定位。实验结果表明,本文方法定位完成时间短、检测准确度较高、定位费用消耗较低。
In the current laser spot center detection and positioning method,there are common problems such as long positioning completion time,low detection accuracy,and high positioning cost consumption. A laser spot center detection and localization method based on center fitting algorithm is proposed. By analyzing the laser spot,the image is denoised by median wave filtering,and the processed image is segmented and extracted by laser using the adaptive threshold method. The center of the laser image is detected by Sobel operator. The center fitting algorithm is used to locate the center. The experimental results show that the proposed method has a short positioning time,high detection accuracy and low positioning cost.
