【摘要】 高分辨率卫星影像的出现为提取特定目标的空间结构信息提供了物质基础。通过分析一组不同分辨率的同一地区的模拟遥感影像 ,讨论了不同分辨率对遥感影像中识别人造地物的影响 ,并从定性定量两个方面解释了影响产生的原因 ,为从遥感影像中识别特定地物提供了参考分辨率 ,同时也为以识别人造地物为目标的遥感图像分割提供了有益的探索。更多还原

【Abstract】 Feature of spectrum, shape and spatial construction are the key on recognizing high ground resolution image from satellites, but what size is the best for recognition of the man-made ground object in the high ground resolution image?For solving the question, the group of simulated images with the different ground resolution are produced at the same region, and the effect of different resolution simulated images are explained by image segmentation and image interpretation, the optimum resolution for indentifying the airfield is presented based on the experiments. Furthermore, the approach is used to recognize other man-made objects.更多还原
