| 摘 要： | 线性构造是指遥感图像上直线状或者曲线状的地表线性影像，为了对线性构造目视解译和计算机自动解译结果进行比较，基于高分一号卫星遥感影像进行 RGB 彩色合成和低通滤波处理，达到图像增强的目的，并分别采用人工目视解译和计算机自动解译方法提取线性构造信息，对得到的数据进行统计分析，分别作相应的雷达图和密度图，并进行非参数检验和相关性分析。结果显示，雷达图所体现的线性构造的最优选方位均为50°；密度图高值区均呈现 NE-SW 两向延长分布；非参数检验的显著性值为 0.843；Pearson 相关系数为 0.552。研究表明，人工目视解译和计算机自动解译结果一致性较好，并具有较强的内在相关性，因此在线性构造研究中，计算机自动解译可作为对传统人工目视解译的一种辅助和验证手段。

| Abstract: | Linear structure refers to the linear or curvilinear surface image on the remote sensing image. In order to compare the results of visual interpretation of linear structure with the results of computer automatic interpretation，RGB color synthesis and low-pass filtering processing are carried out based on the remote sensing image of high score satellite 1 to achieve image enhancement，and the linear structure information is extracted by artificial visual interpretation and computer automatic interpretation respectively. Statistical analy?sis on the data is made，corresponding radar map and density map are made respectively，and non parameter test and correlation analysis are carried out. The results show that the optimal azimuth of linear structure reflected in radar map is 50 °；the high value areas of density map show NE-SW two-way extended distribution；the significance value of nonparametric test is 0.843；the Pearson correlation coefficient is 0.552. The research shows that the results of manual visual interpretation and computer automatic interpretation are consistent，and have strong internal correlation. Therefore，in the study of linear structure，computer automatic interpretation can be used as an auxiliary and verification means for traditional manual visual interpretation. |
