3Dsurvey vs Meshroom

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.

Meshroom is a free, node-based visual programming toolbox for creating and running data-processing pipelines. Its AliceVision plugin combines photogrammetry, camera tracking, HDR panorama, lidar meshing, raw image conversion and color calibration workflows. Users connect operations visually to set dependencies, data flow and execution order. Pipelines can run locally or on distributed systems, including local and remote computation in one project. The meshroom_batch command-line interface and JSON pipeline definitions support automated, reproducible execution. Meshroom reuses cached intermediate results and invalidates affected downstream nodes when attributes change. Built-in viewers display logs, images, 3D data and node outputs. Dynamically loaded plugins can run in separate virtual environments, while Meshroom Hub offers domain-specific plugins for computer vision, AI and other tasks. Prebuilt desktop releases are available for Linux and Windows; macOS requires manual packaging. The software is linked to the Mozilla Public License 2.0. Its listed plan costs nothing.
