ShapeMetriX3D is an innovative System to acquire surfaces with three-dimensional images. For data acquisition a standard digital camera is used which is calibrated by software from 3G Software & Measurement. With the calibrated camera the designated area is imaged from two different angles. Only a range pole must be placed in the imaging are in beforehand (see Figure 1) – the time need for the complete data acquisition process (establishment of range pole, taking two pictures) is about 1 minute. Common applications are within tunnelling, mining, and for different kind of documentation. An important characteristic of ShapeMetriX3D is that a 3D assessment software component is included. After data acquisition on site the images are transferred on a standard PC and processed into a three-dimensional image using the SMX Reconstructor software. The used principle is stereo-photogrammetry with certain extensions, such as having no need for reference markers to determine the relative orientation of the images among each other.
