In order to efficiently obtain basic surveying and mapping data for uninhabited islands,this article adopted unmanned aerial vehicle(UAV)-based tilt photogrammetry without image control to survey and draw uninhabited islands.Through experimental data,it can be concluded after three-dimensional(3D)real scene modeling without image control,the maximum error at the checkpoint plane position is 17.57 cm,with a mean square error of 13.83 cm.The maximum error in elevation is-17.63 cm,with a mean square error of 11.54 cm.These results satisfy the corresponding accuracy requirements for digital line graphics of 1∶500 scale.It can be seen that UAV-based tilt photogrammetry without image control can play an important role in the basic surveying and mapping of uninhabited islands while ensuring measurement accuracy.
