Introduction

This application marks lanes on dashcam videos and calculates the position of the car/curvature of the lane

Tools

Python OpenCV Library

Implementation Details

  1. Compute the camera calibration matrix and distortion coefficients given a set of chessboard images shot by the camera.

  2. Apply a distortion correction to raw images (straight the curved lines). Example

  3. Use color transforms, gradients, etc., to create a thresholded binary image. Example

  4. Apply a perspective transform to rectify binary image ("birds-eye view"). Example

  5. Detect lane pixels and fit to find the lane boundary. Example

  6. Determine the curvature of the lane and vehicle position with respect to center.

  7. Warp the detected lane boundaries back onto the original image. Example

  8. Output visual display of the lane boundaries and numerical estimation of lane curvature and vehicle position. Example
