                                                                                                                                                                     那么大家對表面缺陷檢測有什么了解么?知道其工作原理是如何的?接下來跟隨陜西永輝的小編一起來了解下吧!

                                                                                                                                                                     主要包括圖像獲取模塊、圖像處理模塊、圖像分析模塊、數據管理及人機接口模塊。

                                                                                                                                                              表面缺陷檢測流程

                                                                                                                                                                圖像獲取模塊由工業用相機、光學鏡頭、光源及其夾持裝置等構成,具有完成產品表面圖像獲取的功能。 在光源的照明下,通過光學鏡頭將產品表面成像在照相機的傳感器上,光信號先轉換為電信號,再轉換為計算機能夠處理的數字信號。 目前,工業攝像機主要是基于CCD或CMOS芯片的攝像機。 CCD是目前機器視覺中最常用的圖像傳感器。

                                                                                                                                                                機器的視覺光源直接影響圖像的質量,起到克服環境光的干擾,確保圖像的穩定性,獲得對比度盡可能高的圖像的作用。 目前常用的光源有鹵素燈、熒光燈和發光二次管( LED  )。 LED光源以體積小、功耗低、響應速度快、發光單色性好、可靠性高、光均勻穩定、易于集成等優點得到廣泛應用

                                                                                                                                                                    在日常的應用中,我們如果需要對某件產品進行表面缺陷檢測,那么就首先需要提出檢測的需求,諸如長度、外形等等,在此之外我們需要提出精度的要求,以便服務公司對視覺檢測設備更好的選型!
