It focuses on detecting and understanding the drivable space, ground plane estimation, and semantic segmentation from sensor data.\n\n---\n\n## Project Overview\n\nSelf-driving cars rely heavily on environment perception to navigate safely and efficiently. This project implements fundamental perception tasks such as:\n\n- Ground plane estimation from 3D point clouds or depth data\n- Semantic segmentation of road scenes to identify drivable space and obstacles\n- Lane and obstacle detection using image and sensor fusion\n\nThese tasks collectively help the autonomous vehicle understand its surroundings to make safe driving decisions.\n\n---\n\n## Notebook Structure\n\nThe notebook is organized into **three main sections**, each focusing on a critical aspect of environment perception:\n\n### 1. **Ground Plane Estimation**\n- Objective: Fit a plane model to 3D point cloud data to identify the ground surface.\n- Techniques: RANSAC algorithm is used for robust plane fitting by rejecting outliers.\n- Outcome: The equation of the ground plane is computed, enabling filtering of points close to this plane.\n\n### 2. **Semantic Segmentation and Drivable Space Estimation**\n- Objective: Use semantic segmentation neural network outputs to classify pixels into categories such as road, lane markings, vehicles, and pedestrians.\n- Techniques: Deep learning models for pixel-wise classification, followed by spatial filtering.\n- Outcome: Drivable areas are extracted by thresholding semantic labels, creating a mask that highlights safe driving regions.\n\n### 3. **Lane and Obstacle Detection**\n- Objective: Detect lane lines and obstacles within the segmented drivable space.\n- Techniques: Image processing methods such as edge detection, Hough transform for line detection, and clustering for obstacles.\n- Outcome: Lane boundaries and obstacles are detected, allowing for path planning and collision avoidance.\n\n---\n\n## Flow Diagram\n\n```plaintext\n+------------------------+          +------------------------------+          +-----------------------------+\n|                        |          |                              |          |                             |\n| 1.
