Accuracy Analysis of Low Altitude Photogrammetry with Wide-angle Camera
Firstly, the relationship between the accuracy of low altitude aerial photogrammetry and the field angle of camera is made by a quantitative analysis from the theory. The conclusion that the low altitude photogrammetry should use wide-angle camera as much as possible is done. Then, the limitation of...

| description | Firstly, the relationship between the accuracy of low altitude aerial photogrammetry and the field angle of camera is made by a quantitative analysis from the theory. The conclusion that the low altitude photogrammetry should use wide-angle camera as much as possible is done. Then, the limitation of the single lens camera to expand field angle and the combined wide-angle camera existing on the market not suitable for light load of low altitude UAV(Unmanned Aerial Vehicle) due to excessive weight are pointed out. The characteristics of combined wide-angle low altitude light camera with self-calibration and self-stabilization developed by the author are described, especially the principle of self-calibration for the combination of static error and dynamic error. Based on the practice of large scale mapping, a technical procedure in aerial photography by taking with wide-angle camera and large overlap simultaneously for improving the accuracy of low altitude photogrammetry is proposed. The typical engineering produced data is used to verity the above theoretical analysis. A technical route for increasing accuracy of low altitude photogrammetry with combined wide-angle camera is expounded. |
