                                                                                                                                                                  在工業自動化中,我們出于對產品檢測的需求,進一步提高效率,行業引進了機器視覺檢測系統,利用機器代替人眼,高速相機的高幀率來應對整個自動化產線提出高速需求。

                                                                                                                                                                     而今天小編要帶大家了解的是表面視覺檢測系統,這一系統隸屬于2D視覺,也是機器視覺行業最先發展的一個領域,不管從發展時間,還是難易程度,這項技術在如今的工業自動化領域已經趨于成熟。

                                                                                                                                                                  表面質量檢測對工業品質量管理有極其重要的意義,也是公司視覺和圖像系統事業部多年來專注、聚焦的戰略方向。 表面質量檢測中,印刷品的缺陷、PCB的短路斷線、LCD畫面的色斑亮點等很多缺陷的物理表現是表面圖案的變化,檢測這些缺陷最典型的方法是根據拍攝的表面圖像進行分析。 這種基于平面圖像信息的缺陷判定是現有的表面質量視覺檢測技術的方法。 但是,只局限于二維信息進行質量分析,并不能完全滿足產品、工藝的檢測要求。 工業品表面質量檢測中,存在幾個對3D信息要求的典型應用場景:

                                                                                                                                                              表面機器視覺檢測系統

                                                                                                                                                                表面質量檢查中,雖然有印刷物的傷痕、電子產品表面的傷痕、PCB的導線的凹陷等深度變化,但PCB的多銅(短路、銅渣等)和不足銅)斷線、針孔、缺口等實際上也有深度變化。 對于深度缺陷,一種檢測方式通過光源的設計,加強或減弱圖像的表現,將后處理納入傳統的表面圖像檢測流程。 一種方法是通過測量深度變化的具體值的方法,進行表面深度的測量;

                                                                                                                                                                     以上是我們今天分享的視覺檢測內容,當然根據產線的需求,行業不可能簡簡單單的滿足于2D視覺,目前我們已經在發展3D視覺,雖然在這一領域行業起步不久,但是如陜西永輝電子等公司在該領域已經有不少的相關案例值得大家借鑒了。

                                                                                                                                                                    當然如果大家有關于機器視覺的問題,可以私信或者致電陜西永輝,我們將竭誠給您最中肯的建議或者方案。
