Recently, I installed opencv with the following command:
brew install opencv
I found opencv3 was installed in dir /usr/include and /usr/lib. But what I want is opencv2. How can install opencv2 with the brew command?

The easiest way to find the answer is to use brew search to look for available packages. So, in your case:
brew search opencv
There you will see the package opencv@2 listed. So, you need:
brew install opencv@2

I can't give you a answer in context of using brew but I can assist you with a valuable resource that really helped me out when I was first started out with OpenCV that got me up and developing https://www.youtube.com/watch?v=U49CVY8yOxw
Install Xcode , Install C-Make
Download OpenCV source code https://github.com/opencv/opencv/releases/tag/3.1.0
- Build and install!
INSTRUCTIONS: Go inside OpenCV once downloaded create new folder called build. Next, open CMake GUI find the directory we just created " build " to build the binaries, Click configure, Select "Unix Makefiles" and use native default compilers. cd into out build directory in our OpenCV folder so something like this /Users/you/Desktop/openCvFolder/build and run the command "make" and go have a coffee! I hope this helps it helped me out when I first started experimenting a year ago with OpenCV
