Data page has been updated. Now, you can find more open source UAV datasets suitable for photogrammetric R&D.
More specifically, a link to “The Zurich Urban Micro Aerial Vehicle Dataset” Images of a GoPro camera installed on a UAV flying at low altitudes (5-15 meters above the ground) has been added. This dataset could be used to test a monicular SLAM approach. You can see one sample image here:

ISPRS UseGeo Datasets has also been added that contain 3 datasets of 820 aerial images.
Camera calibration could be computed from a set of images taken from a chess board. LiDAR and photogrammetric point clouds are also available for three datasets, which make them ideal for photogrammetric R&D. Here is a sample image of this dataset:
