基于Lensphoto系统的多基线近景摄影测量在大比例尺测图中的应用

Application of multi-baseline digital close range photogrammetry based on Lensphoto system to large scale topographic map

本文对基于多基线近景摄影测量技术,以Lensphotov2.0系统作为内业处理平台,研究其技术优势;按照数字近景摄影测量方法研究大比例尺测图中的内、外业作业工序。取得的结果与传统数字化测图方法进行对比,研究及试验表明,以Lensphotov2.0系统作为内业处理平台结合非量测数码相机,应用于大比例尺地形测绘,满足精度要求,此方法是可行的。

Based on multi baseline digital close range photogrammetry technology and regarded Lensphotov2. 0 system as platform for the project,this paper researches its technique advantages and figures out the working procedures of large scale measuring based on digital close range photogrammetry measurements. Comparing to the traditional digital mapping methods,experimental study shows that Lensphotov2. 0 processing platform can be used to the large scale topographic mapping with non metric digital camera and meet the accuracy requirements. It is proved that close range photography based on multi-baseline has acquired the advisable achievements by ordinary no-metric cameras.
