摘　　要：影像黑边问题极大地影响了三维GIS平台中高压走廊三维地形场景的展示效果。为解决这一问题,提出一种基于阈值和区域生长法的高压走廊影像黑边去除法。首先,根据黑边分布特征,自动选取种子点。通过给生长判别准则添加阈值约束条件,克服区域生长过程中过生长或欠生长的缺陷。再根据分割结果,去除原始影像中的黑边。该方法简单易行,数据批处理速度快,黑色区域分割结果准确。The problem ofimages' black border will greatly deduce the 3D terrain scene display effectiveness of high voltage corridor in 3D GIS platform. To solve this problem, this paper proposed a method to remove the black borders of high voltage corridor images based on threshold and region growing. First, according to the characteristics of the black border distribution, the seed points were automatically extracted. Then, the paper overcame the over growing and owe growing by adding the threshold constraint to growing criterion. Finally, the paper removed the black borders in the original image on the basis of the segmentation result. The proposed method is simple and efficient, and the black area segmentation results are accurate.
