Unmanned Aerial Vehicles (UAV) is being used extensively in the field of mapping. However, practical applications nowadays mainly use UAV equipment to fly and create terrain and cadastral maps primarily without much research into 3D modeling and 3D mapping from UAV data. The objective of this paper is to study the 3D model of Suoi Hai reservoir in Ba Vi district from UAV image data captured from Drone Inspire 1 equipment. There are two procedures: First, take photos for the image processing of Drone Inspire 1 (a cheap UAV device) and perform image matching, point cloud, Surface model (DSM) from which to calculate the establishment of digital elevation model (DEM); The second is a tilted photograph to capture surface elements of the terrain to make object models on the surface and to create real 3D model of terrain surfaces.
