          Abstract

          This research aims to investigate the potential use of three-dimensional (3D) technologies for the analysis and interpretation of heritage sites. This article uses different 3D survey technologies to find the most appropriate methods to document archaeological stratigraphy, based on diverse environmental conditions, light exposures, and varied surfaces. The use of 3D laser scanners and dense stereo matching (DSM) techniques is now well established in archaeology. However, no convincing comparisons between those techniques have been presented. This research fills this gap to provide an accurate data assessment for the Las Cuevas site (Belize) and represents a starting point for the definition of a sharable methodology. Tests in Las Cuevas were conducted to compare both accuracy and density reliability in cave environments using two different techniques: triangulation light laser scanner and DSM. This study finds that DSM is the most economical, portable, and flexible approach for the 3D documentation of archaeological sites today. In fact, DSM allows the 3D documentation process to be done more efficiently, reducing both data acquisition and processing time. Nonetheless, the quantitative comparison presented in this paper underscores the need to integrate this technique with other technologies when the data acquisition of micro-stratigraphy is required.
