Abstract :
Height accuracy is one of the most important requirements of stereo mapping. In order to improve the height accuracy of airborne photogrammetry, a new method using a multi-camera system was developed. This method collects multiple groups of stereo images with 60% overlap between adjacent stations, and with 90% overlap between simultaneous images. In this way, redundant stereo images are acquired to improve the height accuracy of ground points. This paper presents the principle of this method and a validation experiment conduced in the geometric test field in Hebei province, China. The experimental results reveal that the height accuracy of a four-camera system is better than result of a single camera. Therefore, the proposed method provides a new way for improving the height accuracy of airborne photogrammetry.
