Photogrammetry (SfM-MVS) survey of rural historical heritage in the Pampean region. The “Primera Estancia”, Magdalena, Buenos Aires, Argentina

Abstract

We present a 3D virtual model generated with Structure from Motion Multi-View Stereo (SfM-MVS) of a house, formerly used as a dwelling by farmworkers, located in the cattle ranch named “Primera Estancia”. The ranch, a private property located in the coastal area of Buenos Aires province, has an important cultural and natural heritage. The survey included the acquisition and processing of photographs to generate a 3D model. This model produces a photorealistic result, on which a series of visualizations and analyses can be performed: recording of pathologies, obtaining of measurements in the laboratory, and generation of a record to evaluate the preservation state. We highlight the potential of this technique in light of the loss of local heritage. It also has advantages such as the reduction of the time and effort in data collection with an in situ, non-destructive, and low-cost technique. This technique also allows obtaining reconstructions with detail and precision, useful for research and science communication. It is a very important tool for the socialization of knowledge, and dissemination of the local heritage.
