3DUNDERWORLD-SLS vs Dot3D

3DUNDERWORLD-SLS is a free Linux project that reconstructs point clouds from camera image sequences illuminated by patterned light. Its structured-light process has CPU and GPU implementations, and the command-line program can save reconstructed models as PLY or OBJ files. Version 4.x requires two or more cameras and provides a generic camera interface that programmers can extend. Camera acquisition is not implemented, so users must supply a camera class through the provided interfaces. The project accepts camera image folders, calibration files, and a patterned-light projector as inputs. It does not provide real-time capture or mesh reconstruction. Libraries are included for integration into other projects, with CPU and GPU examples, and an API was included in OpenCV 3.1 for a stereo approach using time-multiplexing Gray encoding. The repository supplies demo binaries, example data, and CMake build instructions. Dependencies are OpenCV 2, CUDA 6.0 or later, and glm. CUDA detection enables CPU and GPU constructors; without CUDA, only the CPU constructor is generated.

Dot3D is professional 3D capture and scanning software for digitizing complex environments on mobile devices. It supports large indoor and outdoor scene scans, loop closure, appending scenes, and annotations during capture. Scan refinement options include coded targets, survey control coordinates, distance constraints, wall-to-wall measurements, and planarity constraints. Dot3D Edit offers editing and processing without scanning, including cropping, measurement, annotation, and export. Supported platforms are iOS, Android, and Windows. Capture inputs include iPhone Pro and Pro Max models from 12 onward, iPad Pro from 2020 onward, Orbbec Gemini 336L, listed Intel RealSense cameras, DPI-10, and DPI-X. Prime supports Orbbec and RealSense depth cameras on Windows and Android; its real-time RTK/GNSS feature requires iOS. Exports include DP, E57, LAS, LAZ, PTS, PTX, PLY, PTG, RCS, and POD, with RCS and POD limited to Windows. The maker says captured data stays on the local device unless explicitly sent to DotProduct. The seven-day all-access trial reverts to Free mode without automatic charge, but Free mode has no exports. Dot3D is based in Norwood, Massachusetts, USA.
