This is a small program to estimate the single camera position and orientation when given pictures of a pattern.

To run this program, you'll have to install
Python 2.7.xand the following modules:numpy,scipy,matplotlibOpenCV 2.xMy version is2.4.11
On Linux, you can type this line in Terminal to install all Python modules:
$ sudo apt-get install python-dev python-numpy python-matplotlib python-scipy
On Mac OSX, you can do:
$ pip install numpy matplotlib scipy
Or I highly recommend to install Anaconda which would automatically install all necessary Python libraries on your local computer.
My version of Anaconda is 4.2.9. More information for Anaconda, please check here.
Another huge advantage of using Anaconda is its simplification of installing Python OpenCV.
You may find painful to download OpenCV source code and compile by yourself.
By Anaconda, you could just type this line in your Terminal:
conda install opencv
If this does not work, check more on this thread
Before run, make sure that you have the pattern image in folder pattern and images in folder images.
But you can actually modify the directories in file src/settings.py. The paths mentioned above are just set by default.
Everything is already setup when you download all files from this repository, you can just type python src/main.py on your local Terminal and then play with the model shown up.
If you want to add some more pictures, you can add them in the folder images and then modify the code block in src/main.py.
This program is coded in Mac OSX environment, so Mac users do not need to do any modifications on the code.
But since OpenCV on Mac have some issue on function cv2.imread, it rotates the input image by 90 degree counter-clockwise sometimes when the image is too huge.
So there is one line to rotate it back in the code. If you are not using Mac, try to run the code at first, and if it does not work well, delete Line 37 in file camera_pose_estimate.py and try it again (sorry for Windows users （＞人＜；）).
Enjoy :)
