Porting to mac os x / xcode #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I have been trying to port your program to compile for mac os x under a xcode 
project.

For this I had to change some of your code.
I am not an expert in C/C++ so if you find I am wrong at some point please 
correct me.

Steps I have made:

1st: I changed most of your includes to a more dynamic style such as 
<OpenCV/OpenCV.h>, <OpenCV/highgui.h>.

2nd: I opted to remove the support for freeglut for the time being and changed 
the writing code to use standard glut library that is included 
with mac os x.

3rd: I had problems while linking files due to some declarations on ehtc.h. To 
solve this I moved some declarations to the .cpp files and 
flaged others as extern.

I have a prototype working version at the moment and including a zip with all 
the files attached fr your consideration.

Issues:

I am having issues while running the code.
The program runs properly for a bit (10-20 seconds) some times just a couple of 
seconds and breaks with the following error:

Objects involved in the operation:

}

Any Idea of what would be causing this problem?
Have you faced with the same problem before?

I detected that the error I describe above occurs when moving the head fast in 
front of the camera.

Actually, this is a bug.
A fast workaround would be to disable ransac in the config.ini file.
In order to do so, just create a data directory with a config.ini file, like 
this:
yourapp/youExecutable.exe
yourapp/data/config.ini
In the config file, put something like:
USE_RANSAC 0
RANSAC_SAMPLES 6
RANSAC_DISTANCE_THRESHOLD 30.0
RANSAC_ITERATIONS 20
CAMERA_INDEX 0
OPEN_MOVIE NO
And you should be fine, while the bug is not corrected.
