The first week of July 2019 was an intensive and productive week for WARMEST. UGR organized two training actions. “Thermography applied to heritage analysis” and “Thermography applied to the Court of the Lions columns”, was lectured by Dr. M. Paz Sáez-Pérez, author of a Doctoral Thesis on the Court of the Lions columns conservation and researcher at WARMEST UGR team. The workshops had two parts, the first one theoretical where WARMEST researchers learned about thermography applied to heritage and the use of the Camera FLIR T1020, one of the most powerful and accurate of the market, able to deliver detailed, smooth pictures with very little image noise that keep you from missing any potential issues during inspections. FLIR Vision Processing produces brilliant thermal images with up to 3.1 million pixels. The second part was hands on at the Alhambra the Court of the Lions, using the camera in the columns of the Lions Court during the following 5 days.
The third workshop, “Light Scanner applied to heritage analysis”, was lectured by José Luis Ramos, researcher at IMUDS-UGR (Research Institute for Health and Sports). Mr. Ramos is a specialist in the use of Light Scanner and Laser Scanner.
WARMEST researchers who attended the workshop at the iMUDS headquarters were able to learn the use of scanning tools in the scanning of objects and the human figure and its different uses at a sporting and industrial level. The objective is to evaluate its possible application in the scanning of the columns of the Court of the Lions of the Alhambra. The presentation was centered on the Artec EVA model as well as the control of the data obtained through the Artec Studio software.
The Artec EVA model has an infrared camera for spatial data and two other cameras to capture textures, taking photos at 16 FPS. The Artec Studio software is used to monitor in real time the results of the camera scanning, join the different captures to obtain the mesh and apply final texture to the object, as well as a final export process to standard formats for 3D modeling.
During the workshop, researchers performed different tests in order to study each of the steps of the process and analyze the conditions, limitations and alternatives for the proper use of a scanner like this in a space like the Court of the Lions and the particularity of its columns.
