    摘要:

    基于仿生學(xué)思想設(shè)計了一種果實簇識別與采摘順序規(guī)劃方法。該方法以Itti視覺注意基本模型為基礎(chǔ),,通過改進視覺特征整合方法,,構(gòu)建依賴先驗知識的視覺顯著圖,,改善果實簇的識別效果;借鑒“贏者取全”的生物神經(jīng)競爭機制和采摘專業(yè)人員的操作經(jīng)驗,,設(shè)計距離、面積和顯著度加權(quán)擇優(yōu)的采摘順序規(guī)劃策略,提高采摘工作效率,。試驗結(jié)果表明,設(shè)計的算法能夠識別20余種常見果蔬,,識別正確率達到93.36%,;果實簇的采摘順序規(guī)劃結(jié)果符合人工采摘的專家經(jīng)驗。

    Abstract:

    To improve algorithm versatility and picking efficiency, recognizing more kinds of fruits or vegetables and planning picking sequence for fruit clusters in visual field have become hotspots and trends of harvesting robot research. Primates can find objects and shift attention through visual selective attention mechanism, which has similarities with harvesting robots to recognize targets and to plan picking sequence. Hence, by adopting the idea and technology of bionics, a new visual selective attentionbased method was proposed for fruit cluster recognition and picking sequence planning. According to Itti visual attention computational model, this algorithm changed computing process for color feature maps, and improved feature integration method for building color conspicuity map and saliency map by introducing priori knowledge about fruits and vegetables. Using the reference of the biological neural network competition mechanism called WinnerTakeAll and artificial expertise from professional picking operators, distance, area and saliency were adopted to design the weighted preferential picking sequence strategy for fruit clusters. The experimental results showed that the proposed method in this paper achieved recognition of more than 23 kinds of familiar fruits and vegetables. Recognition correctness was higher than 93.36%. In addition, the results of picking sequence planning showed that its planning way was consistent with artificial expertise from manual picking operation.
