RESUMEN
This study shows the results of the analysis of the photogrammetric use of 360-degree cameras in complex heritage-related scenes. The goal is to take advantage of the large field of view provided by these sensors and reduce the number of images used to cover the entire scene compared to those needed using conventional cameras. We also try to minimize problems derived from camera geometry and lens characteristics. In this regard, we used a multi-sensor camera composed of six fisheye lenses, applying photogrammetric procedures to several funerary structures. The methodology includes the analysis of several types of spherical images obtained using different stitching techniques and the comparison of the results of image orientation processes considering these images and the original fisheye images. Subsequently, we analyze the possible use of the fisheye images to model complex scenes by reducing the use of ground control points, thus minimizing the need to apply surveying techniques to determine their coordinates. In this regard, we applied distance constraints based on a previous extrinsic calibration of the camera, obtaining results similar to those obtained using a traditional schema based on points. The results have allowed us to determine the advantages and disadvantages of each type of image and configuration, providing several recommendations regarding their use in complex scenes.
RESUMEN
This article explores the relationships and tensions between ethnicity and health, describing the perspectives of various social actors on a Mapuche clinic in the context of a national health program. A qualitative methodology was used to carry out this case study of the Mapuche clinic "La Ruka," located in an urban area of the Metropolitan Region of Chile. The study analyzes the narratives of traditional health practitioners (including a machi, lawentuchefe, lonko, and intercultural facilitator), consumers, conventional healthcare professionals, and local health authorities and community leaders who share a physical, political, and symbolic space around the Mapuche health experience. The systemization of experiences method was applied to the data, acquired through nonparticipant observation, individual interviews, and focus groups. The results suggest that this healthcare experience is highly valued by its protagonists. However, there is a tension surrounding cultural diversity programs that recognize non-Western approaches to healing, such as indigenous practices. This study examines the health-related, cultural, and political tensions involved in projecting indigenous traditions into a homogenizing space such as healthcare in a multicultural neoliberalism system.
