Title: Photogrammetry applied to drone image acquisition

This course will focus on the use of the PIX4D software utility, allowing photogrammetric processing of the drone image data acquired. Use is made of data sets that have already been acquired to demonstrate the use of the software to get the best results. Topics included in the course are firstly : introduction / background on photogrammetry using airborne and stereo satellite images, design of image acquisition plan, camera settings, georeferencing and use of ground control points.

Next focus will be on the use and application of the Pix4D software. After initial processing and extraction of the point cloud and mesh the  ortho mosaic and dsm / dtm will be created and exported to be used in open and free GIS and RS software tools.

Figure below shows the pix4d steps executed and the results obtained (like the ortho image mosaic and the dsm)
