针对仓储物料的计数问题，提出了一种基于视觉检测的自动计数方法，通过对圆形物料端面图像的识别实现物料的自动计数。以OpenCV库函数为基础，采用目标颜色全局阈值化及去孔洞等处理实现物料与背景的分割，使用边缘轮廓提取、Hough圆检测、圆心聚类分析等方法实现对物料的计数；根据物料堆放规律等先验知识对结果进行修正。该方法也适用于摆放不整齐的仓储物料的计数，可同时处理直径不同的仓储物料计数问题。实验结果表明了该方法的精度、鲁棒性和实时性。
針對倉儲物料的計數問題，提齣瞭一種基于視覺檢測的自動計數方法，通過對圓形物料耑麵圖像的識彆實現物料的自動計數。以OpenCV庫函數為基礎，採用目標顏色全跼閾值化及去孔洞等處理實現物料與揹景的分割，使用邊緣輪廓提取、Hough圓檢測、圓心聚類分析等方法實現對物料的計數；根據物料堆放規律等先驗知識對結果進行脩正。該方法也適用于襬放不整齊的倉儲物料的計數，可同時處理直徑不同的倉儲物料計數問題。實驗結果錶明瞭該方法的精度、魯棒性和實時性。

A warehouse material automatic counting method based on visual inspection was investigated and designed,which was able to count warehouse materials automatically by recognizing the round material ends.Based on OpenCV functions,it applied threshold segmentation and void filling to segment materials from background.Edge detection,circle Hough detection and clus-ter analysis were introduced to count the segmented material.Prior knowledge was used to revise the counting results.Experi-ment results showed that the proposed method was of satisfactory precision,robustness and speed,it could also handle conditions with materials in irregular arrangement and different diameters.
