Visual-Odometry

This project explains how to implement a visual odometry for a stereo camera system. Stereo Matching of the images is done using Semi Global Block Matching.

Input Dataset

Please downlaod the dataset from this drive link.

Packages needed

• Opencv2
• Numpy
• Numba
• Matplotlib
• scipy

Steps to Run the code

git clone --recursive https://github.com/karanamrahul/Visual-Odometry.git
cd Visual-Odometry
python3 stereovision.py

You need to select the dataset and the method you want to use for stereo matching. ( Using Semi Global might take a little more time compared to the first method as it checks for four directions around the pixel)

Please choose the dataset number (1) - Curule (2) - Octagon (3) - Pendulum : 


Please choose the method number (1) - Simple Block Matching  (2) - Semi Global Block Matching :
