Up until now no appropriate models have been proposed that are capable to describe the stochastic characteristics of reflectorless rangefinders - the key component of terrestrial laser scanners. This state has to be rated as unsatisfactory especially from the perception of Geodesy where comprehensive knowledge about the precision of measurements is of vital importance, for instance to weigh individual observations or to reveal outliers. In order to tackle this problem, a novel intensity-based stochastic model for the reflectorless rangefinder of a Zoller + Fröhlich Imager 5006 h is experimentally derived. This model accommodates the influence of the interaction between the emitted signal and object surface as well as the acquisition configuration on distance measurements. Based on two different experiments the stochastic model has been successfully verified for three chosen sampling rates. © 2016 International Society for Photogrammetry and Remote Sensing, Inc.

INCEPTION realises innovation in 3D modelling of cultural heritage through an inclusive approach for time-dynamic 3D reconstruction of artefacts, built and social environments. It enriches the European identity through understanding of how European cultural heritage continuously evolves over long periods of time. INCEPTIONs Inclusive approach comprises: time dynamics of 3D reconstruction (forever); addresses scientists, engineers, authorities and citizens (for everybody); and provides methods and tools applicable across Europe (from everywhere). INCEPTION solves the shortcomings of state-of-the-art 3D reconstruction by significantly enhancing the functionalities, capabilities and cost-effectiveness of instruments and deployment procedures for 3D laser survey, data acquisition and processing. It solves the accuracy and efficiency of 3D capturing by integrating Geospatial Information, Global and Indoor Positioning Systems (GIS, GPS, IPS) both through hardware interfaces as well as software algorithms. INCEPTION methods and tools will result in 3D models that are easily accessible for all user groups and interoperable for use by different hardware and software. It develops an open-standard Semantic Web platform for Building Information Models for Cultural Heritage (HBIM) to be implemented in user-friendly Augmented Reality (VR and AR) operable on mobile devices. INCEPTION collaborative research and demonstration involves all disciplines (both social and technical sciences), technologies and sectors essential for creation and use of 3D models of cultural heritage. SMEs are the thrust of INCEPTION consortium that will bring the innovation into creative industries of design, manufacturing and ICT. The Consortium is fully supported by a Stakeholder Panel that represents an international organisation (UNESCO), European and national public institutions, and NGOs in all fields of cultural heritage.

The sensor market of rapid 3D survey is growing rapidly. A precise determination of geometric features is the basis, but complementary information gain in importance. To minimize downtimes the sensor must efficiently detect primary information. The LSR laser camera of Technical University of Munich generated spatial depth and intensity maps. However, more detailed information requires further physical parameters. Z+F develops highly accurate 2D and 3D survey technology and registers precisely 3D pixels with HDR and thermal image data. The geometry turns to be support of complementary information levels.
