cing led to reliable results. In addition, for bundle adjustment ex
periments, expanding the error ellipse and restricting the weight
matrix in the object space for linear features using different iden
tification codes for the line end points resulted in relatively high
er errors in comparison to the other used approaches. However,
results were still acceptable.
Future research will focus on the automation of the extraction of
linear and areal features from photogrammetric and LiDAR data
as well as establishing the correspondence between conjugate
primitives. In addition, we will apply the proposed methodologies
on line cameras. Moreover, we will study the possibility of using
the proposed approaches for both LiDAR and camera calibration.
Furthermore, we will utilize the EOP extracted from the proposed
approaches to generate true orthophotos. Finally, we will
investigate the development of new visualization tools for an
easier portrayal of the registration outcomes such as draping
orthophotos on LiDAR data to provide 3D textured models.
