3D model of the selected object

The aim of the thesis was to assess the accuracy of photogrammetric results from images taken with a low-cost Xiaomi Mi 10T Pro camera and a professional digital SLR camera Canon EOS 6D Mark II with a 24 mm fixed lens. The chapel of St. John of Nepomuk near Guntramovice was chosen as the subject for the images. Forty-nine insertion and control points were targeted and scanned at the chapel. Block and beam alignment and creation of 3D mesh models was performed in Bentley ContexCapture software. The standard deviations of all three axes (X, Y, Z) and positional standard deviation on the control points and deviations relative to a reference point cloud acquired with a ground-based laser scanner were statistically tested. The results show that, with the right imaging and processing methods, comparable results can be achieved using a low-cost camera.

3D model of the selected object

The subject of this diploma thesis is the creation of four georeferenced 3D models of the Chapel of Virgin Mary Help in Brno-Líšeň using images from two cameras, a digital reflex camera Canon EOS 6D Mark II and a low-cost camera Xiaomi Mi 10T Pro mobile phone, in two photogrammetric software, Bentley ContextCapture and Agisoft Metashape Professional. The accuracy of the models was analysed using checkpoints measured by a total station and a reference point cloud from the laser scanning of the chapel. One of the models was presented using Sketchfab on the internet, another one was 3D printed.
