簡介

由於公司採購的AVT相機不足，需要用Basler相機來彌補，所以我也瞭解了一下Basler這款相機的SDK。由於Basler這邊的相機提供的沒有提供Qt的示例，所以我做一個分享出來。

本篇的Demo採用的是工業黑白相機。工業應用中，如果我們要處理的是與影象顏色有關，那麼我們最好採用彩色工業相機；如果不是，那麼我們最好選用黑白工業相機，因為在同樣解析度下的工業相機，黑白工業教學精度比彩色工業相機高，尤其是在看影象邊緣的時候，黑白工業相機的效果更好。

開發環境

• Qt: 5.6.2vc2013版
• Basler: 5.0.11版

效果圖

上圖只是做了SDK部分介面的獲取和設定。相機的觸發方式、曝光時間、增益、頻率，以及圖片的尺寸、燈的觸發訊號等。
