Different approaches and tools are required in Cultural Heritage Documentation to deal with the complexity of monuments and sites.\udThe documentation process has strongly changed in the last few years, always driven by technology. <i>Accurate documentation is\udclosely relied to advances of technology (imaging sensors, high speed scanning, automation in recording and processing data) for\udthe purposes of conservation works, management, appraisal, assessment of the structural condition, archiving, publication and\udresearch (Patias et al., 2008). We want to focus in this paper on the recording aspects of cultural heritage documentation, especially\udthe generation of geometric and photorealistic 3D models for accurate reconstruction and visualization purposes. The selected\udapproaches are based on the combination of photogrammetric dense matching and Terrestrial Laser Scanning (TLS) techniques.\udBoth techniques have pros and cons and recent advances have changed the way of the recording approach. The choice of the best\udworkflow relies on the site configuration, the performances of the sensors, and criteria as geometry, accuracy, resolution, georeferencing,\udtexture, and of course processing time. TLS techniques (time of flight or phase shift systems) are widely used for\udrecording large and complex objects and sites. Point cloud generation from images by dense stereo or multi-view matching can be\udused as an alternative or as a complementary method to TLS. Compared to TLS, the photogrammetric solution is a low cost one, as\udthe acquisition system is limited to a high-performance digital camera and a few accessories only. Indeed, the stereo or multi-view\udmatching process offers a cheap, flexible and accurate solution to get 3D point clouds. Moreover, the captured images might also be\udused for models texturing. Several software packages are available, whether web-based, open source or commercial. The main\udadvantage of this photogrammetric or computer vision based technology is to get at the same time a point cloud (the resolution\uddepends on the size of the pixel on the object), and therefore an accurate meshed object with its texture. After matching and\udprocessing steps, we can use the resulting data in much the same way as a TLS point cloud, but in addition with radiometric\udinformation for textures. \udThe discussion in this paper reviews recording and important processing steps as geo-referencing and data merging, the essential\udassessment of the results, and examples of deliverables from projects of the Photogrammetry and Geomatics Group (INSA\udStrasbourg, France)
