|
摘要
研究目的:结合摄影测量与遥感技术的发展与现状,综述摄影测量与遥感技术在铁路建设中各个方面的应用情况,并分析近年来迅速发展的雷达干涉测量、高分辨率卫星遥感、高光谱遥感等新技术的具体情况及其应用潜力。研究结论:摄影测量与遥感技术在我国铁路建设中的发展有3个趋势:(1)未来5年内遥感将在空间分辨率、光谱分辨率和时间分辨率3个方面出现新的突破,形成高、中、低轨道结合,大、小、微型卫星协同,粗、精、细分辨率互补的遥感网络。(2)“3S”技术的结合,在我国铁路建设中具有广阔的应用前景,是摄影测量与遥感技术在铁路建设应用中的发展趋势之一。(3)遥感技术与虚拟现实技术结合,由此形成的铁路管理和信息服务系统形象地通过计算机提供给公众,为公众提供方便,也是铁路管理和服务未来的发展趋势之一。
Research purposes: In combination with the development and present situation of photographic surveying and remote sensing,the overall comments are made on the application of the technologies of photographic surveying and(remote) sensing in all aspects of railway construction,and also the analysis is made for the concrete situations and their applicable potentiality of rapid raising technologies of radar interfering surveying,high-resolution satellite remote(sensing) and high-spectrum remote sensing. Research conclusions:There are three development trends for photographic surveying and remote sensing being applied in Chinese railway construction.The first one is there will be three new breakthroughs in the aspects of space(resolution),spectrum resolution and time resolution,through which the remote sensing network with low-resolution,medium-(resolution) and high-resolution being relatively complemented each other will be formed in combination with high orbit,medium orbit and low orbit,with the aid of large-sized,medium-sized and small-sized satellites.The second one is photographic surveying and remote sensing along with "3G" technology will be applied widely in Chinese railway(construction).The third one is the railway management information service system will be formed by adopting remote sensing technology along with virtual and realistic techniques.In this way, the system can serve the public vividly and easily with computer.
