Best practices (BP) and guidelines represent a fundamental topic, especially when a given technology matures enough that many users, not totally familiar with it, decide to approach that technology to make it mainstream. This is, for example, the case with 3D modelling methodologies; many users, also non-experts, have tried to approach them, especially after the emergence and diffusion on the market of high quality, non-metric, and relatively cheap digital cameras, together with many software solutions for 3D image-based modelling. If several technical standards have already been adopted for the traditional surveying and dimensional contact metrology fields, it is only in the last few years that BP-related projects and information have appeared in the field of 3D Cultural Heritage (CH). A best practice is a process or method that, when executed effectively, leads to enhanced project performance (Cheok et al., 2008) and ensures, or at least increases, the chance of performing quality data acquisition and subsequent use in a given field (Beraldin et al., 2011). Since documenting is part of a measurement process, the basic principles and practical issues that affect the making of measurements should be considered when dealing with CH documentation. A Good Practice Guide was created by Goldsmith (2010), where six guiding principles to perform good measurements are stated, i.e.: |
