摘　　要：边缘检测是激光雷达图像应用中的关键技术,边缘检测直接影响激光雷达目标识别的效果,结合激光雷达图像的特点,以提高激光雷达图像边缘检测准确性为目标,提出一种基于轮廓波变换和数学形态学的激光雷达图像边缘检测方法。首先采用轮廓波变换对激光雷达图像进行去噪处理,然后采用数学形态学对激光雷达图像腐蚀或膨胀,得到激光雷达图像的边缘,最后在Matlab 2014平台上进行仿真实验。结果结明,本文方法的激光雷达图像边缘检测效果要优于单一的轮廓波变换或数学形态学方法,有效抑制了噪声对激光雷达图像边缘检测的干扰,验证了本文方法的有效性。Edge detection is the key technology in the application of laser radar image, edge detection directly affect the effect of laser radar target recognition, in order to improve the laser radar image edge detecnon accuracy, mls paper proposes a novel edge detection method of laser radar image based on contourlet transform and mathematical morphology combined with the characteristics of the laser radar image. The contourlet transform enhancement is used to process of laser radar image edge information, and secondly the mathematical morphology is used to corrosion or expan- sion laser radar image edge, finally, simulation experiments were conducted on Matlab 2014 platform. Results show, laser radar image edge detection effect of the proposed method is superior to single contour wavelet transform or mathematical morphology method, the noise interference to the edge detection of laser radar image is suppressed, and verify the validity of the method.
