    我仔细研究了一下，发现我的系统上没有安装WindowsSDK。安装它并将Vfw32.lib链接到我的项目。所有LNK2019错误都已解决。

    链接到
    Vfw32.lib
    ——这应该可以解决大部分问题。无法使用
    FlyCapture2:：CameraBase
    one。我可以在这方面获得更多帮助吗？Vfw32.lib在哪里？它随Windows SDK一起提供，它应该是Visual Studio安装的一部分。只要在“项目>属性>链接器>输入>附加依赖项”下提及即可。谢谢！我仔细研究了一下，发现我的系统上没有安装WindowsSDK。安装它并将Vfw32.lib链接到我的项目。除了
    FlyCapture2:：CameraBase
    之外的所有错误都已解决。@IgorTandetnik，如果您将其作为答案发布，我将接受您的解决方案作为答案。
