Offenbart sind ein Verfahren zum 3D-Vermessen einer Umgebung und eine Scananordnung, die zur Durchführung eines derartigen Verfahrens ausgelegt ist, wobei ausgehend von einem durchgeführten Scan mittels räumlicher Analyse der nächste beste Scannerstandpunkt (Next-Best-View) vorgeschlagen wird. A method for the 3D measurement of an environment, for example in an architectural building survey, and a scanning assembly having a 3D laser scanner, said scanning assembly being designed to carry out a method of this type, are disclosed. Proceeding from a performed scan (data capture A), the next best scanner view having the greatest potential both to expand, in the peripheral regions, the already-captured environment geometry and to complete the already-captured environment geometry in itself is proposed by means of spatial analysis (preparation B, analysis C), for example by ray tracing of the voxel cloud (ray tracing 1). The results from the preparation B are superposed and a scan capture is simulated. The position proposals must take into account the physical setup conditions of the scanner measurement setup, e.g. the accessibility, the setup height and a minimum and maximum distance from the previous view. The analysis C of the view candidates is carried out preferably again by means of ray tracing (ray tracing 2).
