                                                                                                                                                                視覺檢測系統的使用可以有效提高檢測效率,節省勞動力,降低生產成本,從而提高經濟效益。

                                                                                                                                                                但由于很多工廠企業買回檢測設備后操作人員經驗不足,在生產過程中一些小問題往往會影響檢測設備的檢測效果。

                                                                                                                                                                硬件選擇

                                                                                                                                                                穩定的圖像特征提取是圖像分析和圖像識別的前提,穩定的圖像傳輸到圖像處理可以保證軟件對圖像處理的準確性。

                                                                                                                                                                很多因素都會影響成像的穩定性,比如周圍環境,物體的變化,視覺硬件的影響。

                                                                                                                                                              視覺檢測

                                                                                                                                                                外觀檢查的硬件選型是一項艱巨的任務,需要工程師熟悉硬件本身和硬件供應商,并有足夠的選型經驗。

                                                                                                                                                                機器視覺系統在實驗室中運行的環境與系統在實際工作場景中運行的環境有很大的不同。

                                                                                                                                                                視覺檢測包括一些重要的部件,如光源、鏡頭、攝像機、圖像采集卡、數據傳輸、圖像處理和測量軟件等。

                                                                                                                                                                隨著各部件性能的提高,機器視覺系統的功能將成倍增加。系統的復雜性取決于具體的應用需求。在選擇組件時,不能只考慮組件的性能是否能滿足要求(如分辨率、幀率、測量算法等。),還要考慮系統的環境條件。

                                                                                                                                                                例如,在工業領域,這些環境條件包括元件變化、轉移、定位、處理界面、振動、環境光、溫度、灰塵、油、水、電磁輻射等。

                                                                                                                                                                在惡劣的條件下,有時需要增加對機器視覺部件的保護。典型的例子就是有些相機需要在相對干凈的環境下使用。但一般情況下,工業環境可以滿足工業相機的直接使用。
