GradeScan® Biological Feature Detection |
Pith To associate knot heads correctly, GradeScan locates the pith of the tree even if the pith is not actually in the board. |
This is a
color image of a twenty foot long, Green Douglas Fir 2 x 8. |
This
is an optimizer image showing of the same board showing
defects on the top face and the location of the pith above the board. The optimizer screen displays the pith in three colors, red when above the board, white when it is interior to the board (or actually on the surface) and blue when the pith is below the board. |
This is an
optimizer image of a different board with pith mostly below but that touches the bottom face for a short distance. The pith location is indicated even when the pith is located opposite a narrow face. A Quality Control Technician can easily tell at a glance if the scanner is working properly. |
