Image EXIF / XMP tags¶

Frame camera interior and exterior parameters can be read from image EXIF / XMP tags. The tables below list required tag sets. If more than one set is present, the first complete set is used.

Interior parameters¶

Tag set	Tag type	XMP Namespace(s)	Camera type
`DewarpData`	XMP	`http://www.dji.com/drone-dji/1.0/`	`brown`
`EXIF_FocalLength` `EXIF_FocalPlaneXResolution` `EXIF_FocalPlaneYResolution` `EXIF_FocalPlaneResolutionUnit`	EXIF		`pinhole`
`EXIF_FocalLengthIn35mmFilm`	EXIF		`pinhole`

Exterior parameters¶

Camera position¶

Tag set	Tag type	XMP Namespace(s)
`GpsLatitude` `GpsLongtitude` `AbsoluteAltitude`	XMP	`http://www.dji.com/drone-dji/1.0/`
`EXIF_GPSLatitudeRef` `EXIF_GPSLongitudeRef` `EXIF_GPSLatitude` `EXIF_GPSLongitude` `EXIF_GPSAltitude`	EXIF

Camera orientation¶

Tag set	Tag type	XMP Namespace(s)
`GimbalRollDegree` `GimbalPitchDegree` `GimbalYawDegree`	XMP	`http://www.dji.com/drone-dji/1.0/`
`Roll` `Pitch` `Yaw`	XMP	`http://ns.sensefly.com/Camera/1.0/` `http://pix4d.com/camera/1.0/`

Note

Conversion from (roll, pitch, yaw) camera orientation is approximate and relies on the world CRS having minimal distortion in the imaged area.

Note

See the test data for examples of images with valid EXIF / XMP tags.

Note

Reading camera parameters from EXIF / XMP tags is currently experimental. If you need support for tags not included above, please see the contribution guide.
