An application for calibrating procam system with a small board, whatever the projector's focusing distance is.

Projector Camera Calibration

This an application for calibrating procam system practically. User calibrates the system with a small board (about B4 paper size), whatever the projector's focusing distance is.

Compatibility

Current version only works on Linux

Pre-requirements

1. CMAKE 2.8
2. OpenCV 3.1.0
3. PCL 1.7
4. OpenSceneGraph 3.4.0
5. xinerama, X11

Compilation

1. Checkout the directory
2. mkdir build
3. cd build
4. cmake ..
5. make

Usage

Print function help: ./procamcalib -? -i : input stream name (filename or camera ID) -o : output file name -b : file including points coordinates on calibration board -p : file including points coordinates to project -n : number of views -r : record the calibration input (both the video stream and n images used for calibration)

Example: ./procamcalib -i 1 -b ./patterns/B4/B4Pattern.txt -p ./patterns/B4/B4PatternProjected.txt -o calibrationResult -n 10 -r

More patterns are available in ./patterns/

Calibration Issue

Hi Limingyang,

Good day! Thanks very much for your work!
I used your code for calibration, using a zed mini camera and a projector.
Since zed mini camera is not directly supported, I tried to use offline calibration. First I tried to use a saved .avi file, however, I had the issue saying that "There is no input video stream from file ". I think this might be caused by by OpenCV issue. So I took several images, and set them as -i parameters. It can be read, however, it has the issue "Unable to stop the stream: Inappropriate ioctl for device". I think it get stuck in some loops. Could you please tell me how should I solve the problem?

Thanks again for your work and reply!

Having a lot of missing files when cmaking the code.

Most of the missing things are from OSG and PCL even though I have linked the path of the build folder. I compiled the PCL from the github (using their 1.7.0 version) and the OSG is from https://launchpad.net/ubuntu/+source/openscenegraph-3.4/3.4.0+dfsg1-4ubuntu1 and both of them have so many path can't be found. Is there any recommended source for these libraries?

What camera to use?

I used the intel realsense camera and kinect one and they didn't work. Will you tell me the exact camera you used in the video?

Porting to OpenCV 4

Thanks for this intuitive projector camera calibration tool.

I tried to port the the code to OpenCV 4, unfortunately there are some methods in liblgc which are not compatible with OpenCV 4.
Is there a way to port the library too?

Is this tool working? Can I use it for Kinect One (v2) projector calibration?

Hi, I am an italian research scholar. I'm working on Projective Augmented Reality with a robotic head. Unfortunately, I still have problems with Camera (I'm using a Kinect One) - Projector calibration.

I have:

1. Realized with my supervisor a new ProCam Calibration tool based on Matlab ProCamCalib toolbox (https://code.google.com/archive/p/procamcalib/) with automatic splitting and recognition of projected and physical chessboards, but this gives us not perfect results (residual reprojection error about 1... px)

2. Conveniently modified the promising 3D Scanning Software (http://mesh.brown.edu/calibration/) to make it able to work with Kinect One but there is something to change that avoids to manage good results.

Therefore, I'd like to know if your pro_cam_calib tool here shared works properly and I can use it to solve my problems calibrating a Kinect One (v2) with a fixed-focus Optoma pocket projector.

Thank you in advance,

Michele Mambrini
