`oty exif`¶

Frame camera models can be derived from image EXIF / XMP tags with oty exif. The EXIF / XMP documentation describes the required tags. This example orthorectifies drone imagery using an OpenDroneMap generated DSM. Ortho images are placed in the current directory:

oty exif --dem odm/odm_dem/dsm.tif odm/images/*.tif

The world / ortho CRS defaults to a UTM CRS whose zone covers the camera positions. This can be changed with --crs:

oty exif --dem odm/odm_dem/dsm.tif --crs EPSG:32651 odm/images/*.tif

Note

EXIF / XMP tag values typically contain inaccuracies that can result in distortion and positioning errors in the ortho images. This is the case with the Orthority test data, and a general limitation of this approach.
