Hybrid Testbed for Image Segmentation Control

This repository contains a hybrid testbed project for image segmentation control, utilizing various tools and techniques for open loop control and ROS implementation.

Project Structure

  • Hybrid-Testbed
    • Open Loop Control
      • Contains scripts and resources for open loop control implementation.
    • ROS Implementation
      • Contains scripts and resources for ROS (Robot Operating System) implementation.

Features

  • Live Video Feed: Start and stop live video feed from a Basler camera.
  • Display Options: Choose between different image segmentation techniques including lines, blobs, color, edges, contours, shapes, or both lines and blobs.
  • Graphical Display: Real-time plots of line and blob detection counts.
  • Save Data: Save the processed image data (timestamp, line count, blob count) to a CSV file.

Requirements

  • Python 3.x
  • tkinter
  • pypylon
  • opencv-python
  • numpy
  • matplotlib
  • Pillow
  • ROS (for ROS implementation)

Installation

  1. Clone the repository:

    git clone https://github.com/yourusername/hybrid-testbed.git
cd hybrid-testbed

  2. Install dependencies:

    pip install tkinter pypylon opencv-python numpy matplotlib Pillow

  3. ROS Installation: Follow the official ROS installation guide for your operating system. ROS Installation Guide

Usage

Open Loop Control

  1. Navigate to the Open Loop Control directory:

    cd Hybrid-Testbed/Open Loop Control

  2. Run the application:

    python open_loop_control.py

  3. Control the application through the GUI:

    • Click "Start Video Feed" to begin the live video feed.
    • Select the desired image segmentation technique from the display options.
    • Click "Stop Video Feed" to stop the live video feed.
    • Click "Save Data" to open a file dialog and choose where to save the CSV file with the processed image data.

ROS Implementation

  1. Navigate to the ROS Implementation directory:

    cd Hybrid-Testbed/ROS Implementation

  2. Follow the instructions in the README within the ROS Implementation directory to set up and run the ROS nodes.

GUI Elements

  • Video Feed Label: Displays the live video feed from the camera.
  • Start/Stop Video Buttons: Control the live video feed.
  • Display Options: Radio buttons to choose the type of image segmentation.
  • Save Data Button: Opens a file dialog to save the CSV file.
  • Real-time Plots: Displays plots of line and blob detection counts.

Code Overview

  • initialize_gui(): Sets up the GUI elements.
  • setup_camera(): Configures the Basler camera.
  • start_video_feed() / stop_video_feed(): Starts and stops the live video feed.
  • update_camera_feed(): Continuously retrieves images from the camera.
  • process_image(): Processes each frame from the camera according to the selected display option.
  • save_data(): Saves the collected image data to a CSV file.
  • detect_lines() / detect_blobs() / color_segmentation() / edge_detection() / contour_detection() / shape_detection(): Image segmentation methods.
