摘要：This article addresses a methodology and the experience gained on automatic exterior image orientation by using current information existing in GIS database. The proposed approach automatically extracts and matches feature points in evenly distributed patches on aerial and ortho images. The elevation of successfully matched points on the aerial image will then be obtained through interpolation calculation on the DTM data in the database. Robust bundle adjustment with great redundancy is therefore conducted to estimate the exterior orientation parameters. An innovative algorithm is proposed for mono-image intersection by using thus obtained exterior orientation parameters and current DTM data. The proposed approach is evaluated based on manually measured a great number of check points. Tests and analyses showed that for the ground points obtained through mono-image intersection, the planimetric accuracy is better than 1pixel, which fulfills the requirement of orthoimage production for database updating purpose. The elevation accuracy is solely dependent on the current DTM and its interpolation applied on it, which reaches 0.003% flying height in this relative flat test area
