我现在正在使用MATLAB完全编写的数据采集工具。我的同事希望我用MATLAB编写这个工具，以便他们可以扩展和修改它。
这个软件需要从两个连接的USB摄像头中获取图片。这些相机的API是用C ++编写的，并且有文档记录-> 这里。
问题在于：当我编写一个抓取图片的mex文件时，它会包括相机的初始化和配置加载，这需要很长时间。如果我想通过这种方式抓取图片，MATLAB需要超过1秒钟才能完成任务。一旦初始化完成，相机就能够录制和发送100 fps。我需要能够将每个记录的图像发送回MATLAB。因为所需的记录会话大约需要12小时，我们需要一个具有轻微后处理的实时屏幕。
是否可能在mex文件中生成一个循环，该循环向MATLAB发送数据，然后等待来自MATLAB的返回信号并继续进行？这样，我就可以初始化相机并定期将图像发送到MATLAB。
我是C++初学者，很可能我不理解为什么这不可能的基本概念。
感谢您提供任何建议或资源，我可以查看。
请在下面找到使用Basler提供的Pylon API初始化相机的代码。
