I have a file full of photo's taken with a 3DR drone over a small coffee farm in Peru. My intention is to create an Orthomosaic of these photos and than use the mosaic to automate a vegetation analysis all with open source software.

I have tested AirPhotoSE, but I am running into an 'IO Error' after importing my photos and the program crashes constantly.

VisualSFM was similarly unsuccessful. Despite having downloaded the supplementary applications ( SiftGPU, PBA, and VLFeat SIFT), whenever I attempt to 'Compute Missing Matches' I get these error messages:

```
     ERROR: siftgpu failed the detection test!!
     SIFT: 0000, 4000x3000,     ERROR1
     ERROR: unable to locate sift binary.

```

I am wondering if anyone can suggest another program or approach I can take. QGIS seems like a good next program to test. 

Can QGIS make georectified orthomosaics of a group of jpegs?
