The presented research is focused on a critical analysis of methodological survey approach related to 3D massive acquisition of Cultural Heritage assets. Starting from the authors' experiences in 3D CH acquisition during the last 15 years, the aim of the paper is to outline critically some pipeline bottlenecks still present in the 3D acquisition process. A short state of art about instruments and methodological evolution in such area support this evaluation, suggesting the opportunity for a mature comparison on the current 3D detection methods, their potential and limits, waiting for the latter to be overcome again in the nearly future. As example, a complex project experience in Pompeii is presented, highlighting some bounds and methodological aspects to control the entire 3D survey process and get results useful for Cultural Heritage understanding.
