Running ORB-SLAM2 on a Mac

[apatzer]

Just got ORB_SLAM2 up and running on a Mac. This was a bit problematic, so I thought this might help some of you.

For those who are interested you may run into the following issues:

• You need to use GCC rather than the default CLang compiler. I did a brew install gcc then set these environment variables:

export CC=gcc-5
export CXX=g++-5
export CPP=cpp-5
export LD=gcc-5

• Can't find tr1/memory or tr1/unordered_map: This seems to be an issue with Boost brew install boost --cc=gcc-5 --build-from-source and was resolved by adding -I/usr/local/Cellar/boost/1.60.0_2/include/boost/tr1/tr1 into the DBoW2 and g20 CMake files.

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS}  -Wall  -O3 -march=native -I/usr/local/Cellar/boost/1.60.0_2/include/boost/tr1/tr1")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall  -O3 -march=native -I/usr/local/Cellar/boost/1.60.0_2/include/boost/tr1/tr1")

Nice job! I have made a Xcode version of ORB SLAM2 which runs CLang on Mac：https://github.com/skylook/ORB_SLAM2 Also I made some useful modification on it. Hopefully this would help :)

@skylook: by the way, i am happy you used the binary dictionary. At lest the evening i spent going through git tutorials was not totally in vain :)

@skylook Nice. But without Pangolin, how do you visualize what's going on? Speaking of which on a Mac Pangolin works fine alone, but in ORB-SLAM2 I keep getting CATransaction uncommitted, indicating the core animation thread is not working. Any suggestion to get around this AND have good visualization (eg Pangolin)?

[skylook]

Thanks @poine your job really helps me :)

@apatzer I remove Pangolin and other viewers because they are hard to port to other devices like iOS & Android. But if you just want to have a good visualization on Mac you can use OpenCV to project points like the code in Examples/Monocular/Main.cc.

There is also a good example of shomin & poine (https://github.com/shomin/ORB_SLAM2) which sepreate Pangolin and viewers may help (but they are not targeted on Mac).

[apatzer]

@skylook Your visualization using OpenCV works perfectly for me, and does not seem to incur any real performance hit for doing the visualization. Thanks!

@apatzer @skylook Hi, could you please tell me where is the file named "Examples/Monocular/Main.cc"?

[skylook]

It's in my git, you can find it here: https://github.com/skylook/ORB_SLAM2/blob/master/Examples/Monocular/Main.cc

[TimingSpace]

@skylook Thank you very much! It works!

[bikong2]

@apatzer i get the same problem with you. i compiled ORB_SLAM2 on mac, and can running successfully when i disable Map and View drawing. but it failed when i enable them. It sames that problem occur because of multi-thread problem, do you have any solutions here?

[shaohuisun-zz]

@apatzer The issue happened to me as well. The main cause for that is viewer thread has to be in the main thread in this case. I don't know why. However, I practically work around it by knowing this.

[Ethan-Zhou]

@hoverpeter Hey, any progress on this pangolin issue? I came across the same problem. Have you figured out how to make the original visualization work without putting the viewer into the main thread?

[pixelcowboy]

@Ethan-Zhou - any luck? Are you able to get working?

@hoverpeter - Can you post your modifications (code sample) for your work around?

Thanks in advance.

[kitizz]

A little late to the game, but I've modified my fork to be (I think) out of the box compatible with Mac. The visualization is in the main thread, and ORB-SLAM itself runs in its own thread. Hasn't been extensively tested, but see how you go. https://github.com/kitizz/ORB_SLAM2

[pixelcowboy]

I've downloaded and tested @kitizz fork. Works good for me on MacOS. Thanks!

Two comments:

1. Cmd line output is "noisy" with "Frame" counter and "CreateNewMapPoints" echoing. Perhaps a debug remnant?

2. Documentation READE.md should be updated according to MacOS support.

Very nice! Again, thanks!

[kitizz]

Woops! Damn. Right you are. Should be fixed up now! I've also clarified that I've only modified the mono_tum executable to get Pangolin working on Mac. The same changes would have to be carried over to any other executable as needed.

Glad it was useful :)

[zhohn0]

@apatzer what's the meaning of last two line

[zhohn0]

@apatzer the boost is 1.66.0 , I can't find "boost/1.60.0_2/include/boost/tr1/tr1". In a word , 1.66.0 don't have"/tr1/tr1".

kitizz‘s repo works. @kitizz thanks~
