Video Traffic Counter
Live: www.traffic-camera.com Development: dev.traffic-camera.com
Realtime video-based object tracking software. Written in C# using Emgu CV. Requires a webcam.
#Development environment setup
Get sources to some dir (say - c:\projects\vtc). Further referenced as REPODIR.
##EmguCV Download the EmguCV libraries here: http://sourceforge.net/projects/emgucv/
- Solution projects are using the path, so no need to fix it.
- Run setup.bat (as Administrator) to create links to huge x86/x64 dirs of EmguCV library.
** (not sure) maybe it's necessary to build solution before the step above, so
binfolder got created.
It's assumed that emgucv-windows-universal 3.0.0.2157 version of EmguCV is installed with default options (IOW - the library installed to C:\Emgu\emgucv-windows-universal 3.0.0.2157\ dir).
##Manifest
- It's necessary to remove manifest to run project on dev machine.
##Image debugger visualizer
During debugging it's useful to view image objects as a raster image, not as a array or bytes. To install image visualizer follow instructions at \Thirdparty\ImageVisualizer\readme.txt.
#Running app
##Using existing video for debugging Pass pathname of local video as command line argument.
##Visualizing unit tests
Use -tests command line arguments to run unit tests (it uses loads DLL specified in UnitTestDll value in app config).
IMPORTANT: unit tests using OWN settings. Check unit test source code to see values!
##Logs
Logs located at %AppData%\VTC\1.0\Logs\ dir.
#Debug output Debug output is written to C:\TrafficCounter\VTClog.txt (see app.config)
##First run
You need to go through the "Configure Regions" dialog the first time you use the application, or whenever it's recompiled, or whenever the intersection is switched.
The ROI mask is the total region of interest. Any movement outside of this region is ignored/masked out.
Each approach is a polygon enclosing a single road entering the intersection. Each exit is a polygon enclosing a single road exiting the intersection.
The regions can overlap - just try to approximately cover one entry or exit area with each approach/exit polygon. For turn detection to work properly, each approach/exit pair has to be on the same road, in the same direction. The approach exit/pairs are selected in counterclockwise order.
Think of the intersection as being a north, south, east and west-travelling road. Then think of starting northbound. The northbound approach would be Approach 1 and the northbound exit would be Exit 1. Approach/Exit 2 would correspond to the westbound approach and exit, and so on.
