摘要
基于数学形态学的边缘检测方法对处理光学经纬仪实际拍摄的含噪声图像与其它常规边缘检测方法相比,具有明显的优势。将空域滤波和Prewitt边缘算子与数学形态学相结合的目标边缘检测方法对图像边缘的检测精度较高,抗噪声能力强,提高了图像边缘检测效果。
The edge detection method based on the mathematical morphology has the remarkable advantage compared with the traditional edge detection method in dealing with the noisy images of the photo-electronic theodolites. The results of the experiment shows that this method combining the spatial filter, Prewitt operator and the mathematical morphology can gain more precise edge pixel and can tolerate more composite noise.
