基于遥感图像的基础上的城市道路自动测绘方法 Based on remote sensing image based on the method of urban road automatic surveying and mapping 城市路途计划建造环境杂乱，因而在运用遥感图画对城市路途测绘时就遇到了诸多困难，比方布景噪音较多，方针鸿沟含糊，以及路途周边修建物、树木以及车辆的暗影遮挡等都会致使致使测绘中止，因而在实践中经常出现GIS数字地图与实践路途状况不符，所以，要有效地完结遥感图画在城市路途测绘中的运用，有必要根据遥感图画创立一种新的办法。 Urban road planning environment, thus when using the remote sensing picture to urban road surveying and mapping has encountered many difficulties, for example sets more noise, policy divide vague, and on the way around the building, trees and vehicles shadow shade and so on will cause the suspension of surveying and mapping, which often occurs in practice of GIS digital maps do not tally with the practical road conditions, therefore, to effectively end the application of remote sensing picture in urban road surveying and mapping, it is necessary according to remote sensing pictures to create a new way. 剖析遥感图画的测绘办法的研讨办法，研讨根据遥感图画的城市路途主动测绘办法的办法，即完布局建方针网络、方针概率符号、空间滑润纠正、矢量标绘丈量4有些，找到处置好每一个进程的办法，即可到达遥感图画对城市路途测绘的需求，详细研讨办法如下： Analysis method of surveying and mapping of remote sensing pictures of seminars, discussion based on remote sensing pictures of city road active way of surveying and mapping method, namely the layout policy network building, policy, space, sucking the correct probability symbols, vector plot 4 some measurement, find good disposal method, each process can reach the demand for urban road surveying and mapping in remote sensing picture, detailed discussion method is as follows: 构建方针网络是运用遥感图画测绘城市路途的首要进程，其进程处置的好坏直接影响整个测绘进程，其意图即为了完成遥感图画布局的完好和明晰。通常状况下，遥感图画中路途方针的内部区域散布均匀，对立大都会集在边际有些，比方存在搅扰噪音或修建、树木等构成的特征区别显着等状况，这直接影响了图画处置的精度。 　 Build policy network is the first process of using the remote sensing picture city on the way of surveying and mapping, its quality directly affects the whole process of disposing of surveying and mapping process, the intent is to complete the remote sensing picture layout intact and clear. Generally situation, the remote sensing picture policy inner
