| dc.description.abstract | The growing use of amateur cameras for several photogrammetric applications such as point determination, three-dimensional reconstruction, measurements and archeological documentation, have ignited studies on the accuracy potential of these categories of cameras. This paper investigates the accuracy potential of Nikon D3200 and Canon EOS 7D amateur cameras for 3D reconstruction of the oldest hostel building in University of Ilorin, Nigeria. Before image collection, a total number of 37 points, 9 control points for image processing and 28 check points for accuracy assessment were strategically marked and coordinated on the building using Sokkia set 520 total Station. Thereafter, multiple overlapping images of the building facade were taken successively with the two cameras in such a way that adjacent pair have end lap of between 80 - 85%. In Agisoft Photoscan, after removing bad images, the photos were aligned. Subsequently, the 3D mesh and textured models wee generated. Corresponding model points of the 28 measured check points were extracted for accuracy determination using the root mean square error (RMSE) analysis. The results showed that both cameras have acceptable point accuracy with the Nikon D3200 producing RMSE of 2.55mm, 3.23mm, 2.51mm and Canon EOS 7D yielded RMSE of 2.77mm, 4.76mm, 2.68mm, in xyz respectively. | en_US |
