Unmanned Aerial Vehicle Low Altitude Remote Sensing System(simply as UAVRS System)is suitable to acquire high image of uprightness and incline on low altitude of a mountainous area.But images are small format, excessive quantities,short,over tilt angle and irregular overlap etc. These are also new problem of the Digital Photogrammetric System that both national and international are facing.This paper provided to resolve the problem of Aerotriangulation in UAVRS image by bundle adjustment with weights observation data. We get valid initial values for bundle adjustment with weights observation data by making block on single model orientation and from improving the accuracy of single model orientation elements. The experiment results have verified that plan accuracy of aerotriangulation is 0.386m and Elevation accuracy is 0.525m. Its accuracy is achieved the need of mapping for 1:2000 DLG.basically.
