                                                                                                                                                                為了保證好的畫面,選擇合適的光源。今天,視覺檢測制造商將教你如何選擇視覺檢測設備。

                                                                                                                                                              機器視覺檢測設備

                                                                                                                                                                光源選擇的基本要素:

                                                                                                                                                                對比度:對比度對于機器視覺非常重要。機器視覺中使用的照明的重要使命是使需求被查詢的特征和需求被忽略的繪圖特征之間形成最大的對比度,然后很容易在特征上產生差異。對比度被定義為特征與其周圍區域之間令人滿意的灰度差異。良好的照明可以確保要檢測的特征從其他場景中脫穎而出。

                                                                                                                                                                亮度:在選擇兩種光源時,更好的選擇是選擇較亮的一種。當光源無法開啟時,可能會出現三種不良情況。排在榜首的,是攝像頭的信噪比不好;因為光源亮度不好,畫面的對比度會不好,畫面出現噪點的可能性會增加。其次,光源亮度不好,需要先增大光圈再減小景深。另外,當光源亮度不好時,自然光等隨機光線會對系統產生很大影響。

                                                                                                                                                                魯棒性:檢查光源的另一種方法是查看光源是否對組件的方向最不敏感。當光源放置在相機視界的不同區域或角度時,效果圖不會改變。方向性強的光源增加了高光區域鏡面反射的可能性,不利于特征提取。

                                                                                                                                                                一個好的光源可以讓你需要尋找的特征變得非常顯著。除了相機可以拍攝零件之外,好的光源可以產生大的對比度、令人滿意的亮度以及對零件方向變化的不敏感性。選好光源后,剩下的作業就短多了。具體的光源選擇方法在于實驗的實踐經驗。
