資料介紹

?針對工業產品手工測量的缺陷，提出一種基于計算機視覺技術的測量方法。根據需要，通過攝像頭從不同角度定時對生產線上的產品進行拍照，首先對獲得的圖像進行去噪、平滑等預處理，然后對其進行基于鏈碼表和線段表的輪廓跟蹤，得到圖像各個封閉區域的邊界信息和區域信息，從而計算產品的面積、周長、形狀因子、重心、外接矩形等幾何特征參數。試驗表明，該方法測試準確率為100%，適合實時檢測，為產品檢測的全自動化研究提供了基礎。

Abstract:: ?Aiming at the drawbacks of tradi tional manual measurement of industrial product,this paper put forward an ap-proach of measurement based on computer vision technology.According to the requirements,the camera timing aims at the production line to take photographs of the products from different angles.Firstly,we did some pre-treatments such as de-nos-ing,smoothing and so on,and then tracked the outline of the image based on the chain codes table and line segment table to get border and region information of all the closed regions,thus computed the geometrical shape feature parameters of the image,such as area,perimeter,shape factor,the center of gravity and circum-rectangular.Experiments show that precision of this method is100%.It is suitable for real-time detection and provides the basic for further research on the fully-automated detection of products.
