Abstract. The following article has as its purpose to solve a series of questions related to the acquisition of fisheye lens images made in the Benchmark FINE, making use of this data and images to generate a reconstruction to the tower of the chapel of San Vigilio in 3D using SFM photogrammetry and its application methodologies using low-cost instruments and sensors such as non-metric digital cameras. The fisheye lens has a wide range of focus and field of view that makes it possible to capture a scene with a limited number of images more quickly and efficiently. An analysis is intended to be carried out on the basis of the results obtained by assessing their accuracy and quality to determine the feasibility in the proposed initial use for the assessment of spaces difficult access by maintaining geometry without distances, scale, defined orientation in images, or ground control points (GPCs).
