最近应做一个视觉项目需要用到映美精相机，在网上搜索了很多资料没有找到相关内容，因此只能自己一步一步的摸索。
一、准备工作 相机型号：ImagingSource DMK 23G445 相机软件：ic_setup_3.4.0，gigecam_setup_3.6.0 其它软件：Qt 5.12.1， vs2017 Community， OpenCV 3.3.0 操作系统：Windows 10 1909 18363.592
Qt .pro配置文件如下（配置文件xxx换上电脑用户名）： QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = imagingSource_CallBack TEMPLATE = app # The following define makes your compiler emit warnings if you use # any feature of Qt which has been marked as deprecated (the exact warnings # depend on your compiler).
