| Summary: | Nowadays, there are various technology are created to facilitate human movement and
work. Until the UAV creation capable to replaced previous photogrammetry technique.
There are many UAV application currently in sync with time circulation such as
military, aerial surveillance, monitoring and survey mapping. Besides of the orthophoto
production, the 3D model reconstruction is also the one of the UAV application. Starting
from aerial photography, the processing phase until 3D modelling is done by using
software. Hence the 3D model also should be performed by the accuracy assessment to
evaluate how far the similarity if compared with the ground measurement and also
actual building. The purpose of this study is to describe the accuracy assessment of 3D
model height extraction from UAV images with different flying altitude in UITM Perlis.
There are several important building blocks selected for 3D model production. After
going through several phase of 3D models production, the height of the building is
compared to the ground measurement value to ensure the height of the building is same
as the actual building height. Other than that, the height of 3D buildings that measured
from different flying altitude are also assessed. The results of this study show that 3d
model produced by the UAV image is able to give a similar height to the field
measurement as well as the actual building. This result suggests building measurements
can be done using this method. |
