Inputs to PIX4Dcloud can be images and text files with ground control points coordinates for cloud processing or 2D/3D results for visualization.
IN THIS ARTICLE
PIX4Dcloud inputs for processing are:
- Images
- (For PIX4Dcloud Advanced users) Ground Control Points (GCPs) file
Images
- At least 6 images are required.
- The formats in the following table are supported.
1 layer (no pyramid, no multi-page)
8, 10, 12, 14, 16 bit integer, floating point
Ground Control Points (GCPs) file
Ground Control Points (GCPs) are used for precisely georeferencing the project.
It is still possible to include GCPs into a PIX4Dcloud dataset. To do so, upload the project files from PIX4Dmapper as described in How to use GCPs for processing on PIX4Dcloud.
A text file containing from four to seven columns per line and a comma (,) to separate the values. No header included.
- Four columns: ID, coordinates
- Five columns: ID, type, coordinates
- Six columns: ID, coordinates, Accuracy Horz, Accuracy Vert
- Seven columns: ID, type, coordinates, Accuracy Horz, Accuracy Vert
All GCPs requirements and more information about the GCPs import format can be found at: AutoGCPs detection functionality.
Inputs for visualizationA dataset can consist of uploaded results only. In this case, no images are processed but the uploaded files are processed for their web-visualization and optimization.
The photogrammetric files that can be uploaded and displayed as results are the following:
- Orthomosaic (.GeoTIFF),
- DSM (.GeoTIFF),
- Index (.GeoTIFF): NDVI map or other index maps
- Point Cloud (.las, .laz),
- 3D Textured Mesh (.obj).
There are some limits in terms of file size and formats for file uploads:
- Orthomosaic: one single GeoTIFF file supported, 50 GB maximum
- DSM: one single GeoTIFF file supported, 50 GB maximum
- Index: one single GeoTIFF file supported, 50 GB maximum
- Point Cloud: one single LAS or LAZ file supported.
- 3D Textured Mesh: one single OBJ+MTL+JPG set of files supported
- OBJ: Maximum 1 GB.
- JPG: Maximum 16k x 16k.
