Alternatives to PIX4Dcatch

{"intro": "PIX4Dcatch focuses on mobile ground scanning. It records image frames with position and orientation information, gives immediate coverage feedback, and builds georeferenced models through photogrammetry and, on iOS, LiDAR depth capture. Discovery is free and includes LiDAR capture, GPS georeferencing, point measurement, and GCP and mark creation. Pro adds RTK support, Gaussian Splatting, AR points, volume computation, and other field tools. Processing stays off the phone: projects need a PIX4Dcloud or PIX4Dmatic license or trial. Android, iOS, and Windows are supported, with exports including point clouds, orthophotos, GIS data, and several 3D formats.\n\nAlternatives become relevant when you need aerial imagery, local processing, broader design workflows, or different device coverage. PIX4Dcatch cloud processing also has a 4,000-image project limit, and cloud uploads require internet access. Phone GNSS is expected to reach only a few meters; centimeter-range absolute accuracy requires a supported RTK receiver and an active regional NTRIP subscription. Compare each option by capture source, processing location, outputs, measurements, offline operation, platform support, and total pricing. A free plan or open-source tool may matter as much as specialized surveying features.", "rows": [{"ref": "sw:polycam", "name": "Polycam", "best_for": "AI-assisted site, object, and floor-plan capture", "pricing": "Free plan; paid from $12.50/mo annually; 7-day trial", "key_difference": "Polycam adds AI-assisted object capture, customizable floor plans, drone mapping, and web access alongside photogrammetry and LiDAR.", "choose_when": "Choose it for shareable object models, editable floor plans, or workflows involving Blender, Unity, SketchUp, or Xactimate."}, {"ref": "sw:realityscan", "name": "RealityScan", "best_for": "High-fidelity desktop photogrammetry and mobile capture", "pricing": "Free plan; paid from $1,250/user/yr; 30-day trial", "key_difference": "RealityScan combines a desktop photogrammetry pipeline with mobile point-cloud feedback, automatic capture, AR scaling, and direct exports.", "choose_when": "Choose it when you need Windows or Linux desktop reconstruction, photorealistic models, or mobile uploads to Sketchfab."}, {"ref": "sw:3dsurvey", "name": "3Dsurvey", "best_for": "Surveying data processing and measurement outputs", "pricing": "From €225/mo; 14-day trial", "key_difference": "3Dsurvey accepts drones, cameras, GNSS, LiDAR, SONAR, geospatial data, and telemetry, then produces extensive surveying outputs and reports.", "choose_when": "Choose it for mixed surveying inputs, CAD and contour tools, or cloud links for viewing projects from any device."}, {"ref": "sw:webodm", "name": "WebODM", "best_for": "Free offline aerial mapping and open workflows", "pricing": "Free plan", "key_difference": "WebODM processes drone photos or videos locally offline and exports maps, point clouds, elevation models, textured models, and Gaussian splats.", "choose_when": "Choose it when free local processing, aerial imagery, open-source integrations, or command-line processing nodes matter."}, {"ref": "sw:3df-zephyr", "name": "3DF Zephyr", "best_for": "Windows photogrammetry with surveying deliverables", "pricing": "Free plan; paid from €199", "key_difference": "3DF Zephyr reconstructs models from photos, camera sensors, drones, and laser scanners, with selectable reconstruction pipelines and surveying deliverables.", "choose_when": "Choose it for Windows-only workflows needing orthomosaics, DEMs, contours, sections, CAD drawings, measurements, or reports."}, {"ref": "sw:colmap", "name": "COLMAP", "best_for": "Programmable Structure-from-Motion and dense reconstruction", "pricing": "Free plan", "key_difference": "COLMAP offers GUI, command-line, Python, and C++ interfaces for sparse and dense reconstruction from ordered or unordered image collections.", "choose_when": "Choose it when you need a free reconstruction pipeline that can be automated, embedded, or customized with supported feature algorithms."}, {"ref": "sw:openmvg", "name": "OpenMVG", "best_for": "Open-source, modifiable multi-view geometry pipelines", "pricing": "Open source", "key_difference": "OpenMVG is a C++ library and pipeline framework for image-based reconstruction, exporting scenes to other multiple-view-stereo systems.", "choose_when": "Choose it for readable, modifiable open-source algorithms, custom structure-from-motion pipelines, or research-oriented integration."}]}
