Images

PIX4Dmatic is based on image processing and is optimized for large-scale, corridor, and terrestrial projects.

Extension	Description
.jpg, .jpeg	JPEG images
.tiff, .tif	TIFF images and depth maps

For more information about the supported cameras see: Which cameras are supported in PIX4Dmatic.

Region of interest (ROI)

PIX4Dmatic allows importing a defined area using .kml files, ensuring precise geographic coordinates for improved alignment and reconstruction of 3D models.

Extension	Description
.kml	A standard format file for storing geographic data, often used for representing points, lines, polygons, and other features in photogrammetry applications.

Image geolocation and orientation

The import of image geolocation and orientation is useful when the values are not available in the EXIF/Xmp tags or when using PPK workflows for better results.

Extension	Description
.csv, .txt	A text file containing seven or nine columns per line and a comma (,) to separate the values Seven columns: ID, coordinates, Yaw, Pitch, Roll Nine columns: ID, coordinates, Yaw, Pitch, Roll, Accuracy Horz, Accuracy Vert

For more information and all formats see Image geolocation and orientation import format articles.

Example: Image geolocation in geographic coordinates, Yaw, Pitch, Roll:

imagename, coordinate1 [decimal degrees], coordinate2 [decimal degrees], z [meter], yaw [decimal degrees], pitch [decimal degrees], roll [decimal degrees]

Ground Control Points (GCPs) file

Ground Control Points (GCPs) are used for precisely georeferencing the project.

Extension	Description
.csv, .txt	A text file containing four or six columns per line and a comma (,) to separate the values. Four columns: ID and coordinates Six columns: ID, coordinates, Accuracy Horz, and Accuracy Vert

For more information and all formats please see the GCPs import format article.

Example: GCPs in projected coordinates with accuracy values:

label,X [units],Y [units],z [units],Accuracy Horz [units],Accuracy Vert [units]

GCP0,2532795.105,1152094.639,395.883,0.02,0.02
GCP1,2532728.805,1152079.825,396.619,0.02,0.02

GCPs marks file

GCPs marks can be imported if they were previously marked and exported in a PIX4Dmapper or PIX4Dmatic project.

Extension	Description
.csv, .txt	A text file containing positions of marks on individual images.

For more information please see the How to import GCP marks from PIX4Dmapper into PIX4Dmatic article.

Processing templates

Custom processing templates can be imported if they were previously saved and exported from a PIX4Dmatic project.

Extension	Description
.json	A file containing a custom processing template including the Title and a Description (Optional)
