In this study, our experiences showed that the laser scanning
data process softwares need more developing and user friendly
tools. Especially automatic mesh generation algorithms aren't
efficiently to create 3D models. Because of false created
triangles, different surfaces that have different elevation could
not be modelled in 3D. Therefore it requires more editing after
the mesh generation.
In this study, because of the used camera, the laser scanner data
were taken a basic system to compare both methods. By
comparing two methods, we may say that the laser scanning
systems may be used in 3D modelling applications instead of
close range photogrammetry but texture information is an
important topic for architectural projects By fusion of single
photograph that had been taken by photogrammetric method
and laser scanning data; the model that contains texture
information had been generated.
We suggest that in the future, using terrestrial scanning systems
will be more effective by developing of user softwares.
