(IN)TANGIBLE HERITAGE(S)

Abstract

This work wishes to put to test the question of if and to what extent have the technological advances in digital image sensors, brought us to a point where cheap consumer hardware and software can act as a useful and reliable scientific tool in tangible heritage documentation. The empiric research presented here concentrates specifically on the recently released Apple LIDAR scanning technology, now built into the new iPhones and iPad Pro, alongside several cheap and even free software applications, designed to make use of the technology. These hardware/software solutions have been tested extensively over a wide range of test cases and compared to other existing solutions, such as Photogrammetry, high-end laser and structured light scanners. Factors such as mobility, ease of use, flexibility, accessibility, and cost, were balanced against the those of quality, consistency, reliability and above all scientific validity. Testing in the field covered multiple aspects of lighting, size, distance, textures, and material surfaces, with the foremost question being that of intent. I.e., what was the research intent and what purpose was the LIDAR scan set out to achieve. In this, ongoing research, the ground is constantly shifting. On the software side, new apps are appearing, and the existing ones are constantly improving. The original Apple LIDAR hardware has not changed over the past year. However, it is safe to assume that both the Apple technology as well as emerging competitor solutions will push the boundaries of the SSL technology forward. So that even areas for which today this technology offers more of a promise than a real solution, are sure to benefit from these consumer tools, tools which will surely change the field of heritage survey, documentation and research in the years to come.
