METHOD OF AUTOMATED DECISION-MAKING ON PURPOSE OF TREES FOR CUTTING IN THEIR PROCESSING WITH TIMBER HARVESTING MACHINE Russian patent published in 2015 - IPC A01G23/00 

FIELD: woodworking industry.

SUBSTANCE: method comprises a breakdown of plantations to sites, forming the technology corridors. The breakdown of plantations is carried out to sites geometrically equal to the work area of the timber harvesting machine for selection cutting of trees on the bands on both sides of the technological corridors. Determining of trees intended for cutting is carried out in automated manner in real-time by obtaining stereoscopic image of the area from the stereo-pair of cameras mounted on the timber harvesting machine. First, the number of trees in the work area of the timber harvesting machine is determined by analysing a stereoscopic image of the space in front of the timber harvesting machine by the method of stereoscopic parallax. Then, the calculation of taxation indices is carried out - the diameter, shape coefficient and the height of the trunk of each tree in the timber harvesting machine work area. Then by the solver based on fuzzy logic based on the data obtained the trees are detected in the timber harvesting machine work area for probable destination for cutting. The tree having maximum probability of destination for cutting is displayed on the operator's monitor of the timber harvesting machine.

EFFECT: enhanced functional capabilities and reduction of complexity of the process of selecting trees for cutting.
