Portable 3Dsurvey 4.0.2 (x64) Multilingual
3Dsurvey Portable is a cutting-edge photogrammetry and geospatial mapping software suite engineered to transform raw aerial, terrestrial, and mobile data into precise, actionable 3D models, orthophotos, point clouds, and topographic surveys. Developed for surveyors, engineers, architects, construction professionals, and environmental scientists, 3Dsurvey Portable stands out as an all-in-one solution that integrates data capture, processing, analysis, and visualization workflows into a single, intuitive platform. By leveraging advanced algorithms for photogrammetry, LiDAR processing, and CAD integration, it delivers centimeter-level accuracy while minimizing the need for multiple specialized tools, enabling users to generate professional-grade deliverables rapidly and efficiently. This comprehensive software empowers teams to map complex terrains, monitor construction sites, assess environmental changes, and support urban planning projects with unprecedented detail and reliability.
Photogrammetry and Data Processing Pipeline
At the core of 3Dsurvey Portable lies its robust photogrammetry engine, which processes images captured from drones, cameras, smartphones, or ground-based setups to reconstruct highly detailed 3D representations of real-world environments. The workflow begins with data import, supporting formats like JPEG, TIFF, and RAW images, alongside LiDAR point clouds, GNSS coordinates, and ground control points (GCPs). Users can align datasets using automatic feature matching or manual tie points, ensuring georeferenced outputs with sub-centimeter precision.
The software’s point cloud generation employs state-of-the-art Structure from Motion (SfM) and Multi-View Stereo (MVS) techniques, producing dense, colored point clouds that capture millions of points per project. Advanced filtering tools allow classification into ground, vegetation, buildings, and water surfaces, with noise reduction and outlier removal for cleaner data. From these point clouds, 3Dsurvey Portable generates digital surface models (DSMs), digital terrain models (DTMs), and true orthophotos, all fully textured and orthorectified for distortion-free mapping.
Batch processing capabilities handle massive datasets—up to billions of points—across multi-core CPUs and GPUs, drastically reducing turnaround times from days to hours. Users control density, resolution, and quality parameters, balancing computational demands with output fidelity.
3D Modeling and Mesh Generation
3Dsurvey Portable excels in creating photorealistic 3D meshes from processed data, suitable for visualization, simulation, and analysis. The mesh generation algorithm reconstructs watertight surfaces with high-fidelity textures derived from input imagery, supporting complex geometries like facades, quarries, or forested areas. Newer iterations introduce enhanced meshing that eliminates common artifacts like ballooning effects in oblique captures, yielding accurate volumetric models.
These meshes integrate seamlessly with the software’s built-in viewer, offering fly-through navigation, sectioning, and measurement tools. Export options include OBJ, PLY, STL, and LAS formats, facilitating compatibility with CAD software like AutoCAD, Revit, or SketchUp for further design work.
Orthophoto and True Orthophoto Production
One of 3Dsurvey Portable’s flagship outputs is high-resolution orthophotos, where aerial images are geometrically corrected and mosaicked into seamless, georeferenced maps. True orthophotos account for building heights and terrain variations, projecting imagery vertically onto the surface for unparalleled accuracy in urban or sloped environments. Resolutions down to 1 cm/pixel enable detection of fine details like cracks, vegetation health, or asset conditions.
Users can clip orthos to custom boundaries, apply color balancing, and generate NDVI (Normalized Difference Vegetation Index) layers for agricultural monitoring. These maps serve as base layers for GIS analysis, overlaying vector data like roads, parcels, or utilities.
CAD and Analysis Tools
Integrated CAD functionality elevates 3Dsurvey Portable beyond mere visualization, embedding vector drafting directly within the 3D environment. Tools for linework, polygons, splines, and annotations allow on-the-fly digitization from point clouds or orthos. Advanced features include trim/extend/intersect operations, area measurement with incomplete data (e.g., inferring hidden corners), and profile/cross-section generation along paths.
Volume calculations support stockpile monitoring, cut/fill analysis, and earthwork estimation, with dynamic updates as models evolve. Contour lines, elevation profiles, and heatmaps visualize topography, aiding civil engineering and mining applications. The measure area tool, powered by improved algorithms, handles irregular surfaces and occluded features, outputting precise metrics to tables or reports.
Registration and Multi-Source Fusion
3Dsurvey Portable’s registration module aligns disparate datasets—drone imagery, terrestrial LiDAR, total station points—using ICP (Iterative Closest Point) algorithms or manual control. Automatic registration minimizes point-to-point distances, while X-Ray views slice through point clouds for floorplan extraction, treating them as CAD planes for rapid outlining.
RTK videogrammetry extends capabilities to smartphone videos, extracting frames for 3D reconstruction in hard-to-reach areas, enhanced by GNSS corrections via the SiteScan app.
Presentation and Sharing Features
Dynamic presentation tools include auto-rotate views for stakeholder demos, time-comparison sliders for change detection, and measurement overlays. 3Dsurvey Portable Cloud enables secure sharing via links, viewable on any device without software installation. Clients access interactive models with annotations, measurements, and exports, fostering collaboration.
Automation and Workflow Optimization
Scriptable workflows and machine learning-based classification automate repetitive tasks like ground filtering or object detection. Coordinate system handling supports global projections (UTM, WGS84) and local grids, with vertical datums for elevation accuracy. Field efficiency improves via reduced processing steps, consolidating SfM, meshing, ortho generation, and CAD into one pipeline.
