Visual Odometry in a 2-D environment
CS-365A Course Project

Under the guidance of:Prof. Amitabha Mukherjee
Introduction
Visual Odometry is the process of estimating the position and orientation of the robot using the camera images associated with it.
Our aim is to determine the location of the robotic arm, having 2 or 3 links with camera mounted on the top of the end effector, by analysing the images of the environment of the robot.
Motivation
Mars Land Rover Mission All those places where GPS can’t be used to
determine one’s location Visual Odometry provides a quite accurate tool to
handle the problem of navigation and finding its location
Approach
Environment: Square shaped box with 4 coloured walls and black corners
Approach Robot: Robotic arm kept at the centre of the box with 2 (or 3)
links and a camera at the end effector. Camera will have 180 field of view and it will emit rays at an angular difference of 1
Approach Images: For different robot configurations (different values of
we will obtain the images dataset. This will be used to train the robot, so that when it encounters a new image, it can determine its configuration.
Approach
Using Isomap Algorithm map the image dataset to 2-D or 3-D space
Using neural network, map it to the configuration space ()
