Once the analysis is finished and final parameters are obtained
from the bundle adjustment, a new set of orientation files is
generated by ORIMA. Within this process the precise
orientation values for each sensor line at Level 0 are computed
based on the adjusted orientation fix parameters and the
observed GPS/IMU values. The photogrammetric mathematical
model is updated with these precise orientation values and more
accurate measurements can be made. The user is now ready to
produce features, DTM, orthophotos, etc.
S. SUMMARY
In this paper we have detailed how a traditional least squares
bundle adjustment process has been augmented to support a
push broom scanner with GPS/IMU data completely. The use of
high precision GPS and IMU data combined with traditional
triangulation techniques gives rise to a robust and very flexible
system. The adjustment process can determine calibration,
datum deficiencies, and errors in GPS, and more precisely
register the imagery to ground control. It should be noted that
very little ground control is required. Owing to the GPS/IMU
data, ground control is essentially unnecessary. For typical
issues of local datum knowledge and quality control, some
ground control is recommended.
