These preliminary results indicate that the proposed scheme can
be used to obtain structure lines without threshold selection that
include the segmentation results.
Future works will focus on the improvement of TEA for corners
and the development of further applications. The evaluation
will be also enhanced to compare with manually edited models
obtained from stereo aerial imagery. In the photogrammetric
perspective, these detected three-dimensional structure lines can
provide initial building information for the development of data
registration and building reconstruction.
5. ACKNOWLEDGEMENT
This study was partially supported by the National Science
Council, Taiwan, under project number 99-2221-E-008-079-
MY3. The FLIMAP LIDAR data was kindly provided by the
faculty of ITC, University of Twente, the Netherlands. The
octree-based split-and-merge segmentation algorithm was
developed by Professor Tseng and Dr. Wang at the National
Cheng Kung University, Taiwan.
