    摘要:

    提出了一種針對高粉塵強腐蝕環(huán)境的復合肥顆粒雙目視覺檢測系統(tǒng),。首先分析檢測系統(tǒng)使用需求,，提出實現連續(xù)大樣本快速檢測、實時顯示結果,、防腐除塵等功能的設計要求,；提出3種雙目視覺檢測方案并進行對比,，確定雙目線陣CCD檢測為可行方案。接著對系統(tǒng)硬件進行配置,，并進行防腐除塵設計,。為提高檢測精度對電磁振動給料機進行自適應伺服控制，采用雙相機并行的圖像處理程序。對檢測系統(tǒng)進行粒度分布實驗,，結果表明,，檢測系統(tǒng)誤差在±3%范圍內，滿足實際應用要求,。

    Abstract:

    Aiming at the compound fertilizer particle inspection for strong corrosive and high dust environment, a kind of inspection system based on binocular vision was proposed. Firstly, using demand of the inspection system was analyzed, and the design requirements which can realize the continuous large sample testing, and result online showing and granulator closed-loop controlling were put forward. Then three binocular visual inspection plans were proposed and compared. Binocular linear CCD inspection was sure for the feasible plan. Hardware configuration, anti-corrosion and dust removal were designed. In order to improve the precision, electromagnetic vibration feeder was servo controlled, which was feedback by robot vision. Also, double cameras parallel image processing program was used. Finally, particle size distribution experiment was executed. The results show that the system error is within ±3%, facilitative for practical application.
