Wisely implemented digital photogrammetry technique enforced with computer vision methods results in smart automated processing system that, on the one hand, can be managed by a new-comer in the field of photogrammetry, yet, on the other hand, has a lot to offer to a specialist who can adjust the workflow to numerous specific tasks and different types of data. Throughout various case studies Metashape proves to produce quality and accurate results.
Photogrammetric triangulation
- Processing of various types of imagery: aerial (nadir, oblique) & close-range.
- Auto calibration: frame (incl. fisheye), spherical & cylindrical cameras.
- Multi camera projects support.
Dense point cloud: editing and classification
- Elaborate model editing for accurate results.
- Points classification to customize geometry reconstruction.
- .LAS export to benefit from classical point data processing workflow.
Digital elevation model: DSM/DTM export
- Digital Surface and/or Digital Terrain Model — depending on the project.
- Georeferncing based on EXIF meta data/flight log: GPS/GCPs data.
- EPSG registry coordinate systems support: WGS84, UTM, etc.
Georeferenced orthomosaic export
- Georeferenced orthomosaic: most-GIS-compatible GeoTIFF format; .KML file to be located on Google Earth.
- Export in blocks for huge projects.
- Color correction for homogeneous texture.
Measurements: distances, areas, volumes
- Inbuilt tools to measure distances, areas and volumes.
- To perform more sophisticated metric analysis Metashape products can be smoothly transferred to external tools thanks to a variety of export formats.
Ground control points: high accuracy surveying
- GCPs import to control accuracy of the results.
- Coded/non-coded targets auto detection for fast GCPs input.
- Scale bar tool to set reference distance without implementation of positioning equipment.
Python scripts: customize processing workflow
- In addition to Batch processing — a way to save on human intervention, Python scripting suggests customization options:
- a parameters template for several similar data sets; intermediate processing results inspection; etc.
Multispectral imagery processing
- RGB/NIR/thermal/multispectral imagery processing.
- Fast reconstruction based on preferable channel.
- Multichannel orthomosaic generation for built-in vegetation indices (NDVI) calculation and export.
3D model: generation and texturing
- Various scenes: archaeological sites, artifacts, buildings, interiors, people, etc.
- Direct upload Sketchfab resource and export to varios popular formats.
- Photorealistic textures: HDR and multifile support.
4D modeling for dynamic scenes
- Multi camera station data processing for creative projects in cinemato- graphic art, game industry, etc.
- Basis for numerous visual effects with 3D models reconstructed in time sequence.
Panorama stitching
- 3D reconstruction for data captured from the same camera position — camera station, provided that at least 2 camera stations are present.
- 360° panorama stitching for one camera station data.
Network processing
- Distributed calculations over a computer network to use combined power of multiple nodes for huge data sets processing in one project.
