Material: Original CT scan log exams, forest inventory
data, internal geometrical models, ERQB simulators.
Original reconstructed images from 5 logs were sent to Cirad
on CD-ROM support or using remote file transfer. The other various data
and models were given by INRA ERQB team. It consist in file formats,
simulation laws and models, basic algorithms, and existing software written
in Visual Basic language. It also consists in user interface requirements
and practical advises.
Methodology : the process data flow.
Process data flow can be summarized as following steps:
Internal geometrical data generation:
from models
from CT scan images
Internal geometrical structure visualization:
from geometrical models
from stand to tree level
from processed images
(CT scan original and labeled images)
external and internal
3D and visualizations, board and veneer sawing simulation.
At every stage of this process needed models developed
at INRA were implemented, and specific algorithms and interface developments
were carried out.
Software development environment.
Software development is performed with an in house methodology
on the basis of:
the C2000 CT scan software also developed at Cirad for medical
applications,
a set of drivers for graphics and file managing available
on UNIX and PC in C and C++ language,a compatible set of internal libraries
running under Windows 95/98/NT and X/OSF_MOTIF on Unix. The software architecture
is based on graphical windows display and dedicated command boxes. Default
configuration parameters can be updated in order to personalize the application.
