What OpenReco is

OpenReco turns drone and camera imagery into point clouds, textured meshes, orthomosaics, and elevation models. Its node-based workspace can run a complete reconstruction graph or individual stages, with cached and reproducible results. The software uses COLMAP CUDA for GPU multi-view stereo and describes an automatic CPU fallback. Models can be georeferenced from EXIF GPS data or ground control points. Analysis tools cover volume, profile, area, and distance measurements, as well as vegetation maps using NDVI, ExG, and VARI. Listed export formats include LAS, LAZ, PLY, OBJ, GeoTIFF, GeoJSON, DXF, CSV, 3D Tiles, and contour SHP. OpenReco is MIT-licensed and open source, with desktop downloads for Windows, macOS, and Linux. The site says it can be downloaded without an account or subscription. Named target areas include surveying and mapping, agriculture and forestry, VFX and heritage, construction and earthworks, and robotics and research.
