基于Inpho数字摄影测量系统下的航片内定向

Interior Orientation of Aerial Photographs Based on Inpho Digital Photogrammetric System

结合湖南吉首地区1∶10 000地形图更新项目,介绍基于Inpho摄影测量系统下对量测式相机获取的航片进行内定向的原理、方法及作业流程,并对内定向的难点和精度做了分析和探讨。生产实践证明,应用Inpho摄影测量系统对航片进行内定向,具有高精度、高效率、方便等优点。

Combined with the update project of 1：10 000 topographic map for an area of Jishou, Hunan province, this paper intro- duces the principle, method and proeess of interior orientation of aerial photograph that comes from metric camera, analyzes the diffi- culty and precision of interior orientation based on the Inpho photogrammetric system. The production practice proves that application of Inpho photogrammetrie system for internal orientation of aerial photograph is of high precision, efficiency, convenience and so on.
