本文接上次的博客海康威视工业相机SDK二次开发（VS+Opencv+QT+海康SDK+C++）（一），上个博客中并未用到QT，本文介绍项目内容及源码，供大家参考。

由于我的项目中是用海康相机作为拍照的一个中介，重点是在目标识别方向，请阅读源码时自动忽略。
如果对目标识别感兴趣，可以参考我的YOLO系列
https://blog.csdn.net/qq_45445740/category_9794819.html

1.说明

1.1 环境配置

关于我在VS中的软件版本及相关的环境配置，请移步
海康威视工业相机SDK二次开发（VS+Opencv+QT+海康SDK+C++）（一）（里面有详细的软硬件介绍）

1.2 背景说明

简单介绍下我的项目需求：
通过相机对物体拍照，后进行目标识别，并返回识别目标的准确位置。这里相机采用海康威视工业相机，人机交互界面选择QT。
界面功能介绍：搜索当前相机的信号，相机可进行图像的连续采集或触发式采集。
