摘　　要：为寻求更适合天绘一号卫星影像的分割方法,文章采用均值偏移分割、分水岭分割、数学形态学分割、连通分量分割4种图像分割方法对天绘一号卫星影像进行分割实验,并从视觉和定量两方面对分割结果进行评估。结果表明:均值偏移方法的分割质量更佳,且分割结果更有利于提升后续处理的效率;几何形态较规则、质地较均一、复杂度较低的地物类型分割质量较高,反之则较低。In order to find suitable image segmentation methods for TH-1 images, the mean shift, watershed, morphological profiles, connected component four segmentation methods were used to seg- ment TH-1 images, and the segmentation results were assessed from visual and quantitative as- pects. Results showed that the mean shift method could get the best segmentation which is good for the el- ficiency of the following processes features that have regular geometry, homogeneous character, low complexity could achieve better segmentation results.
