| Zusammenfassung: | The invention provides a laser radar point cloud data 3D display enhancement method and system. The laser radar point cloud data 3D display enhancement method comprises the steps of M1, performing smoothing processing on gray values of point cloud data and gray values of point cloud data in a 3D neighborhood; M2, calculating a gamma value by utilizing the gray value of the point cloud data subjected to smoothing processing; and M3, performing point cloud data gamma transformation by utilizing the calculated gamma value to realize effective adjustment of the local contrast. The method and system can be applied to 3D display of the laser radar point cloud data, the visual effect of 3D display of the point cloud data is remarkably improved by adaptively adjusting the local contrast, and visual observation of the point cloud data is facilitated.
本发明提供了一种激光雷达点云数据3D显示增强方法及系统，包括：步骤M1：将各点云数据灰度值与3D邻域内点云数据灰度值进行平滑处理；步骤M2：利用平滑处理后点云数据灰度值计算伽马值；步骤M3：利用计算得到的伽马值做点云数据伽马变换，实现局部对比度有效调整。本发明可应用于激光雷达点云数据的3D显示，通过自适应调整局部对比度来显著改善点云数据3 |
