大恒相机HTupleAccessException 大恒相机软件_回调函数_02

第二步:测试相机:MER-1070-10GC相机,应用软件打开该相机体验。

MER-1070-10GC相机为以太网通信的相机,之前开发的项目都是走FlyCapture的sdk,不能开启该相机,所有先测试体验下。

第三步:利用SDK-API进行编程,主要功能(开启、采集、录像、停止、关闭)

重中之重,如何开发所需功能,鄙人使用联合Opencv图像库联合开发。

使用C接口和C++ 接口两个程序分别实现:

总体思路:

初始化接口库——》枚举设备——》打开设备打开流

——》注册设备掉线事件【目前只有千兆网系列相机支持此事件通知】

——》获取远端设备属性控制器

————》注册远端设备事件【属性控制器】

——》注册回调采集(显示)

————》发送开采命令【属性控制器】

————》发送停采命令【属性控制器】

——》注销采集回调

——》注销远端设备事件

——》注销设备掉线事件

——》释放资源

C接口

(参考网上代码,C++的是看接口说明文档进行的)
