PASSENGER COUNTING

This is investigation prototype of application, which main goal is to count number of passengers that travel in a bus journey from point A to point B and also showing the current number of passengers in a bus.

Started 02.05.2020

Local setup

Create a local virtual python environment

pip3 install virtualenv

virtualenv -p python3 python-env

source python-env/bin/activate

Install the dependencies for the project

pip install -r requirements.txt

For windows anaconda can be used to ease installation

Briefly about the algorithm

• get frame
  • every n frame:
    • convert the frame to a blob and pass the blob through the network and obtain the detections
    • loop over detections and filter out weak and useless detections
    • construct a dlib rectangle object and then start the dlib correlation tracker. Add the tracker to our list of trackers
  • else:
    • update the tracker and grab the updated position
    • use the centroid tracker to associate the (1) old object centroids with (2) the newly computed object centroids
  • loop over the tracked objects:
    • check to see if a trackable object exists for the current object ID. Create if there is no existing trackable object
    • otherwise determine utilize it to determine direction and count
  • draw
