| 摘 要： | 我国是土壤侵蚀最严重的国家之一,已经进行了3次全国范围的土壤侵蚀调查,但由于技术所限制,目前利用遥感图像判别土壤侵蚀强度主要是人工判读或人机交互式勾绘。为减轻人工判读勾绘的负担,该文从图像分析的角度,利用基于内容的图像检索技术辅助人工目视解译。并针对计算机和人之间的判读差别,提出结合相关反馈技术来提高检索的精度,实验表明这种思路是可行的。

| Abstract: | China is one of the countries with the most serious soil erosion. Three times investigation on soil eros ion of national extension have been conducted. But limited by technology, at present intensity of soil e-rosion distinguishing by using remote sensing image is mainly relies on manual work distinguish or man-power plus machine drawing. In order to release the burden of manual work distinguish and drawing, this paper uses image researches based on contents to assist manpower eye inspection. According to the differ-ences between computer and manpower distinguish, the paper suggests to link relevant feedback technolo-gy to improve the searches precision. Experiment has proofed that this thought is feasible. |
