摘 要: 结合“航测数模技术在公路路线设计中的应用”课题研究成果,本文介绍了利用该方法进行公路路线设计的计算机辅助设计系统。着重讨论了航测数据处理、挑错、改错及原始数据质量控制的原理及软件编制;论述了散点数模的建立,地面线内插,以及对地物断裂线进行处理等技术问题。通过实际工程考核验证了该软件用于公路路线设计的可行性。 Combining the achievment of research in ' Aerial Survey and Digital Terain Model Technology applied in Highway Route Design', this paper introduces the highway route computer aided design system using this method. It discusses mainly aerial survey data operation, finding mistakes, correcting mistakes, the principle of DTM establishment from dispersed points, interpolation of ground surface, and treatment on surface feature break line, etc. It is proved that appling this software in highway route design is feasible through practical engineering. The system is being applied in highway route construction map design at present.
