UCU Trapezna People Motion Heatmap

Description

This project is created for visualizing and tracking people motion in UCU cafe Trapezna. Based on amount of people and motion speed the program builds live video heatmap which is simple for understanding. The project mostly is intended for UCU students who want to avoid long queue when in Trapezna when they want to it. Heatmap will help to find out how many people is currently in Trapezna.

Installation

$ git clone https://github.com/andrwkoval/trapezna
$ cd trapezna
$ virtualenv -p python3 venv
$ source venv/bin/activate
$ pip3 install -r requirements.txt

Usage

$ cd .../trapezna
$ source venv/bin/activate
$ python3 VideoProcessor.py

Input data

path_file - path to the video to get Heatmap.

Output data

Live video heatmap.

Project Structure

1. Assets (screenshots and images of working examples)
2. config.py (specific configurations for people tracking)
3. PeopleDetector.py
   • detect_people (detects people in specific area and circles them using rectangles)
   • count_people (based on detected people returns amount of them)
4. utils.py (parses date and time from name of the file)
5. VideoProcessor.py (main module for image and video processing)
   • crop_interesting_region (specifies a region on the frame for better interaction)
   • leave_only_persons (colors the regions without people in black)
   • process_frame (thresholds a given frame to use in further processing)
   • adjust_gamma (brightens the frame)
   • prepare_frame (uses Gaussian Blur and histogram equalization to prepare frame for heatmap)
   • compare_with_prev (compares current frame with previous to get the difference in pixels thus get the motion trace)
   • make_heatmap (gets the frame and adds the previous motion, then colours the difference in pixels)
   • initialize (copies current frame)
   • get_next_frame (gets next frame)
   • show_video (visualizes the heatmap and resets traces every 220 frames)
6. requirements.txt (python packages required for project usage)
