A Video-Based System for Vehicle Speed Measurement in Urban Roadways .

vehicledsm is a GStreamer plugin written in C/C++. For compiling the project, the following tools are required:

• libtool
• autoconf
• libgstreamer1.0-dev
• libtesseract-dev
• libleptonica-dev
• gcc 5.5 (or lower)

To download the dataset, do:

  cd dataset
  bash download.sh

Once all dependencies are correctly installed, configure the package and build it with:

  cd gst-plugin
  ./autogen.sh
  make

If everything goes fine, the binary file libgstplugin.so must appear in gst-plugin/gstreamer/.libs.

To inspect that file (check if it is working properly), do:

  cd gst-plugin/tools/
  ./inspect.sh

It should list the properties of the vehicledsm plugin.

To run the software with the provided videos (please download the dataset first if not already done), do:

  cd gst-plugin/tools
  ./run-dsm.sh ../../dataset/set1/

Modify gst-plugin/src/Makefile.am to add or remove source files to build or add additional dependencies or compiler flags or change the name of the plugin file to be installed. Run ./autoregen.sh if changes don't take effect automatically on 'make'.

Modify gst-plugin/configure.ac to check for additional library dependencies or other features needed by your plugin. Run ./autoregen.sh if changes don't take effect automatically on 'make'.

Once the plugin is built you can either install it with 'sudo make install' (however, this will by default go into the /usr/local prefix where it won't be picked up by a GStreamer installed from packages, so you would need to set the GST_PLUGIN_PATH environment variable to include or point to /usr/local/lib/gstreamer-1.0/ for your plugin to be found by a from-package GStreamer). Alternatively, you will find your plugin binary in gst-plugins/src/.libs/ as libgstplugin.so or similar (the extension may vary), so you can also set the GST_PLUGIN_PATH environmen variable to the gst-plugins/src/.libs/ directory (best to specify an absolute path though).

• For some unknown reason, sometimes the software crashes with a SIGSEGV just after launched.
