GradeScan® Biological Feature Detection |
Knots GradeScan uses up to four different sensors to find knot heads on all four sides of the board. The image on the left 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. 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. |
