3Dsurvey vs OpenReco

3Dsurvey is photogrammetry software for processing and classifying surveying data. It creates 3D models, orthophotos, digital elevation models, point clouds, and reports from sources including drones, cameras, GNSS, LiDAR, SONAR, geospatial data, and real-time telemetry. Its extraction tools cover CAD drawing, volume calculation, contour lines, profile lines, and cross sections. Listed formats include TIFF, JPG, PNG, KMZ, OBJ, PLY, E57, LAS, DXF, PDF, TXT, XYZ, DOC, XML, and MP4. Results can be uploaded to 3Dsurvey Cloud Viewer and shared by link for viewing on any device. The maker highlights construction, land surveying, and surface mining. A 14-day trial offers full functionality without data limitations, and a free student license is available for individual non-commercial use. Subscription pricing is €225 per month, billed monthly, or €187.50 per year billed yearly at €2,250, excluding taxes. A perpetual license costs €3,399 one time, excluding taxes.

OpenReco converts drone and camera imagery into dense point clouds, textured meshes, orthomosaics, and elevation models. Its node-based workspace can run a complete reconstruction graph or individual stages, while caching keeps results reproducible. Reconstruction uses COLMAP CUDA for GPU multi-view stereo and includes an automatic CPU fallback. Models can be georeferenced from EXIF GPS data or ground control points. Analysis tools measure volume, profile, area, and distance, and generate NDVI, ExG, and VARI vegetation maps. Listed exports include LAS, LAZ, PLY, OBJ, GeoTIFF, GeoJSON, DXF, CSV, 3D Tiles, and contour SHP. OpenReco is MIT licensed and open source. Desktop downloads are listed for Windows, macOS, and Linux. The site says no account or subscription is needed to download it, and the Free plan is free. Named target fields include surveying and mapping, agriculture and forestry, VFX and heritage, construction and earthworks, and robotics and research.
