OpenCV + Swift 2 + CvVideoCameraDelegate

Hello guys,

I've been studying OpenCV for the last couple of weeks.

I'm developing a project using OpenCV 3, Swift 2, iOS 9. It needs real time camera image acquisition.

I've followed several tutorials in internet (even in japanese, using translator!). But I couldn't use the CvVideoCameraDelegate in the project :/

My Objective C++ wrapper header (called Camera.h) must implement the CvVideoCameraDelegate. But, to be able to know it, I need to include the file opencv2/videoio/cap_ios.h. The image below shows my project and this header file:

My bridge file it only contains this wrapper header (called Camera.h).

But, when I try to build, some errors occurs: Core.hpp/Base.hpp header must be compiled as C++; climits not found.

This happens because the cap_ios.h is inside the .h header. If I don't use the delegate, and include the cap_ios.h only in the .mm, there is no problem.

Well, does anybody knows how to handle this?

Thanks for your support. If there is questions about the problem, please ask.

Hello guys,

I've achieved to make it work, but, to do that, unfortunatelly I had to use the version 2.4.11 of OpenCV. I don't know why the OpenCV 3 version do not work. The only adjustment I had to do is change the include in Camera.h from opencv2/videio/cap_ios.h to highgui/cap_ios.h, the old location of cap_ios.h header.

Does anybody know (or have any clue) why it don't work with OpenCV 3?

Thanks

I was using the pod but it didn't do anything I think there is a lot more involve that just using cocoapods. I can't even find the bridging header file with the cocoapods
