Accuracy Assessment of Photogrammetric Results from Low Cost and Professional Camera

The aim of the article was to assess the accuracy of photogrammetric results using images of a low-cost camera, a Xiaomi Mi 10T Pro mobile phone, and a Canon EOS 6D Mark II professional digital reflex camera. A total of 51 control and checkpoints were created at the chapel, and it was scanned by a terrestrial laser scanner. Bundle block adjustment and mesh model generation were performed using Bentley ContextCapture. 2D standard deviations and standard deviations of elevation at checkpoints and deviations from the reference terrestrial laser scanning point cloud were statistically tested. The results show that with a suitably selected imaging configuration, high-quality photogrammetric results can be achieved even with a low-cost camer
