# Merge Preview

Quickly projects drone images on a map by using georeferencing, camera angles and a global DTM. The images are then merged using ODM's split-merge algorithms.

Quality is obviously not good, works only for nadir-only images and requires the images to have gimbal/camera angle information (not all drones provide this information).

Usage:

```
# Install DDB (required for geoprojection)

curl -fsSL https://get.dronedb.app -o get-ddb.sh
sh get-ddb.sh

# Run

python3 mergepreview.py -i images/*.JPG --size 25%
```
