ORMAL CONDITIONS

iMS3D stands for “indoor Mobile Scanning” and 3D for “3D point cloud”. We remind the user that the
iMS3D is a surveying equipment dedicated to indoor jobs and mainly for building areas. Indeed, the
iMS3D has been build and designed for such environment and every sensor, mechanics and electronic
components has been chosen in order to fit the building measurement requirements.
