Qt（C++）调用工业相机Basler的SDK使用示例

作者：沙振宇

这篇文章主要介绍了Qt（C++）调用工业相机Basler的SDK使用示例，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

简介

由于公司采购的AVT相机不足，需要用Basler相机来弥补，所以我也了解了一下Basler这款相机的SDK。由于Basler这边的相机提供的没有提供Qt的示例，所以我做一个分享出来。

本篇的Demo采用的是工业黑白相机。工业应用中，如果我们要处理的是与图像颜色有关，那么我们最好采用彩色工业相机；如果不是，那么我们最好选用黑白工业相机，因为在同样分辨率下的工业相机，黑白工业教学精度比彩色工业相机高，尤其是在看图像边缘的时候，黑白工业相机的效果更好。

开发环境

效果图

 上图只是做了SDK部分接口的获取和设置。相机的触发方式、曝光时间、增益、频率，以及图片的尺寸、灯的触发信号等。
