Road-Lane-Detection

🚀 Code Description: This code is a Road Lane Detection system using Digital Image Processing techniques. It processes video frames to detect and highlight lane lines on roads. Here's how it works:

1. Initialization:
   • Imports necessary packages such as OpenCV, NumPy, Matplotlib, MoviePy, and others.
2. Image Processing Functions:
   • Contains several functions to process images and detect lane lines, including color selection, grayscale conversion, Gaussian smoothing, Canny edge detection, region selection, Hough Transform, and line drawing.
3. Video Processing:
   • Uses MoviePy to process video frames and apply the lane detection pipeline to each frame.
4. User Interface:
   • Provides a simple graphical interface to select and process videos using Tkinter.

🔍 Code Breakdown:

Image Processing (imgfunc.py)

1. list_images(images, cols=2, rows=5, cmap=None, title=None):
   • Displays a list of images in a single figure using Matplotlib.
2. RGB_color_selection(image):
   • Applies color selection to RGB images to keep only white and yellow lane lines.
3. convert_hsv(image):
   • Converts RGB images to HSV color space.
4. HSV_color_selection(image):
   • Applies color selection to HSV images to keep only white and yellow lane lines.
5. convert_hsl(image):
   • Converts RGB images to HSL color space.
6. HSL_color_selection(image):
   • Applies color selection to HSL images to keep only white and yellow lane lines.
7. gray_scale(image):
   • Converts images to grayscale.
8. gaussian_smoothing(image, kernel_size=13):
   • Applies Gaussian Blur to the input image for smoothing.
9. canny_detector(image, low_threshold=50, high_threshold=150):
   • Applies Canny Edge Detection to the input image.
10. region_selection(image):
    • Defines and applies a mask to keep the region of interest in the image.
11. hough_transform(image):
    • Applies Hough Transform to detect lines in the masked image.
12. draw_lines(image, lines, color=[255, 0, 0], thickness=2):
    • Draws detected lines onto the image.
13. lane_lines(image, lines):
    • Creates full-length lane lines from detected line segments.
14. draw_lane_lines(image, lines, color=[255, 0, 0], thickness=12):
    • Draws lane lines onto the input image.

Video Processing and GUI (vid.py)

1. frame_processor(image):
   • Processes each video frame to detect and highlight lane lines.
2. display_images():
   • Displays processed images from the 'output_images' folder.
3. select_video(root):
   • Allows the user to select a video file for processing.
4. process_video(video_path):
   • Processes the selected video and saves the output with detected lane lines.
5. main():
   • Initializes the Tkinter GUI, sets up the interface, and runs the application.

🔐 Code Specifications:

• Dependencies:

  • The code uses several external modules including OpenCV, NumPy, Matplotlib, MoviePy, Tkinter, and PIL. Ensure these are installed in your environment.

• Customization:

  • Users can adjust parameters such as color thresholds, Gaussian kernel size, Canny edge detection thresholds, and Hough Transform parameters for optimal lane detection performance.

• Folder Structure:

  • Ensure the project contains test_images, test_videos, output_images, and output_videos folders. The myenv and __pycache__ folders are created during environment setup and can be ignored.

• Execution:

  • Run the vid.py script to launch the GUI and select a video for lane detection.
