MetaScan vs MicMac

MetaScan creates 3D models of people and objects through a mobile app or an event scanning service. Its app offers object, full-body and head-and-shoulders capture using photogrammetry on modern iPhone or Android cameras, without requiring LiDAR. Scans can be viewed in augmented reality and exported as GLB, USDZ or OBJ; MetaScan also says they can be auto-rigged and animated for use in its multiplayer game In The Real World. Browser-based converters support GLB, OBJ, STL, glTF, PLY, FBX and USDZ, processing files on the user's device without uploading them. Event services include a scanning station, portrait studio and 360 spin video booth for occasions such as weddings, team days and corporate events. The free plan allows up to five scans in a library and one HD reconstruction per month. Pro costs $9.99 a month, Studio costs $29.99 a month, and an HD credit costs 4.99 USD once. MetaScan says person scans require consent and source images for standard scans are deleted automatically about two hours after model generation. It offers support by phone, text, email or website message.

MicMac is free, open-source desktop software for reconstructing 3D models from imagery. Developed at IGN and ENSG within the LASTIG lab, it runs on Linux, macOS and Windows under the CECILL-B license. It supports frame cameras, pushbroom sensors and scanned analogue images, along with camera calibration models and dense image matching for deformation studies. Outputs can include point clouds, 3D models and ortho-imagery in a desired coordinate system. Intermediate results in open formats let users work at different stages, and quality indicators include bundle adjustment residuals, covariance matrices, parameter sensitivity and correlation images. The C3DC command computes a point cloud from oriented images; AperiCloud creates a sparse cloud with camera positions and orientations for viewing in MeshLab, but does not support 64-bit PLY. MicMac is adapted to big datasets and was initially built for experts and researchers, with use also described in architecture, archaeology and forestry. Documentation, tutorials, a wiki and user forum are available. Building from source involves multiple dependencies, and the Mac guide cautions that a current revision may not compile or may be unstable on a given OS.
