In this paper ,we utilize the imagery with greater 1 meter resolution which is so called very high resolution as experimental data and do the research of ribbon road and simple building roof , and we talk about the process and method of extraction from high-resolution remotely sensed imagery :the representation of road and building in high-resolution image is analyzed ;a method of semi-automatic extraction for ribbon road based on angular texture signature and profile matching is promoted ;a algorithm for road extraction based on Snakes model is compared and analyzed ;the method of object-oriented image analysis and classification is introduced and we utilize this method to extract simple building roof semi-automatically ;the algorithm of road extraction is implemented as prototype system ;finally , the practicability of above-mentioned method are evaluated .

本文以分辨率大于1米的超高分辨率遥感影像作为试验数据，以具有一定宽度的带状道路和简单建筑物屋顶作为研究对象，探讨分析了高分辨率遥感影像中地物要素的半自动提取过程和方法：分析了高分辨率遥感影像中道路和建筑物的特征表现；提出了一种基于角度纹理特征和剖面匹配的带状道路半自动提取方法；对比分析了基于Snakes模型的道路提取算法；介绍了面向对象的图像分析和分类方法，使用该方法对简单建筑物屋顶进行了半自动提取；以原型系统方式对道路提取算法进行了实现；最后结合试验，对上述各种方法在实用性方面进行了评估。

Introduction is made to the rotor spinning frame R40 based on technology of spinning box SC-R by Sussen regarding the advantages up to the world advanced level. Conclusion is made that both the auto and semi-auto rotor spinning frame BT series by Rioter produces quality yarn, with good performance-price ratio, thus leading the semi-auto rotor spinning frame. Sampling the rotor spinning BT923, analysis is done to the tech-edges. Conclusion is made that rotor spinning frame is a new mature spinning technology. It is recommended for China's selection for graded yarn production, yet performance-price is key to its competitiveness.
