We Make The Grade

Knots

Biological Feature Detection

GradeScan uses data from up to six different sensors to find 
knot heads on all four sides of the board. 

The image below is a portion of a 2 x 10 White 
Fir board. The purple boxes show the knot heads 
found by GradeScan on the top surface.

Below is a magnified section of the same board. The 
small magenta box in the middle of the face toward 
the left edge is actually a pitch pocket. GradeScan
was not fooled by the pocket's knot-like color.

GradeScan Knot2


Even the small pin knot on the very edge of the board 
is boxed correctly.

GradeScan's optimizer gathers the data from all sides into a three-dimensional object and calculates the exact knot displacement.
