Evaluación técnica y económica de métodos de levantamiento arquitectónico análogas y digitales

Abstract

Architectural surveys are indispensable to recognize or update the geometry of a building and/or urban space. Nowadays, the methodologies used for this process are characterized by traditional and technological methods, which present a contrast in terms of accuracy, performance and cost. The objective of this research is to evaluate different analog and digital architectural surveying methodologies, comparing technical and economic attributes, in a representative case study. For this purpose, manual and technological procedures were characterized, such as manual meter with flex metro, mobile devices and LIDAR laser scanner; then, on the case study, measurements were performed with the methods mentioned above, establishing performance, accuracy, and cost, ending with the delivery of CAD documents in the post-process of 2D and 3D digitizing. This study allowed to establish that the method with the best performance and accuracy for space scanning is the LIDAR laser scanner with 99% followed by the traditional analog method with 85% and finally the mobile devices with 76%, in turn, in terms of costs, the LIDAR laser scanner technologies have costs close to 600% more compared to mobile devices, and 900% compared to traditional methods.
