- Abstract:
-
Quick and effective detection of wood blocks cross section and acquisition of the required information are the key to improving the efficiency of wood block production and transactions. However, since wood blocks are often densely stacked, their cross sections have high similarity, while their boundaries are not obvious; this poses a great challenge in detecting the cross sections and acquiring the required information. Considering the difficulty in detecting the cross section of highly similar wood blocks under dense stacking, a simple and efficient wood R-CNN network model is proposed in this paper. The detection accuracy is increased by improving the model loss function and the non-maximum suppression algorithm, and detection speed is ensured by simplifying the network structure and modifying the feature pyramid network. A series of experiments prove that the algorithm model can precisely detect the cross sections of blocks with high similarity under dense stacking. Moreover, it can guarantee fast detection speed and good robustness and can be actually used in the production and transaction of wood blocks.
