METHOD AND APPARATUS FOR DETERMINING THE DIMENSIONS AND EXTERNAL PROPERTIES OF THREE-DIMENSIONAL OBJECTS SUCH AS SAWN TIMBER

The present application relates to a method and apparatus for determining the dimensions and external properties of three-dimensional objects such as sawn timber, in which method objects like timber are moved in a transverse position over a target area in conveying direction, the target area is illuminated, and the target area is scanned upwards by a camera. In accordance with the invention each object like timber is scanned or exposed at least twice in the target area, and the timber is conveyed in the target area over support bars, which are in an angle (α) in relation to the conveying direction.
