LearnTechWithUs/Stereo-Vision

This program has been developed as part of a project at the University of Karlsruhe in Germany. The final purpose of the algorithm is to measure the distance to an object by combining two webcams and use them as a Stereo Camera.

What it solves

This project provides a way to measure the distance to an object using a stereo camera setup, helping to overcome the depth perception limitations of single-camera systems.

How it works

The system uses two webcams and a chessboard for calibration. It first removes lens distortion and performs stereo calibration using a set of captured images. It then generates a disparity map and employs a third-order regression to calculate the precise distance to an object selected by the user via a click.

Who it’s for

Developers and students interested in computer vision and distance measurement using stereo cameras.

Highlights

  • Stereo camera calibration using a chessboard pattern.
  • Generation of disparity maps for depth perception.
  • Distance measurement via third-order regression based on user interaction.
