Main activities and responsibilities

UAV Vision Based Navigation.

Project objective was to develop the capability for UAVs (Unmanned Autonomous Vehicles) to navigate in GPS denied environments for an extended period of time exploiting computer vision. For this purpose a PARTICLE FILTER and an EXTENDED KALMAN FILTER have been developed (in C++) and tested for the integration of measurements from a suite of cameras with different orientations, an IMU, and a GPS when available.

Small UAV mission scenario leads to assume limited payload and computational capability, accurate accelerations and rotation rates data coming from the IMU at all times during the mission. IMU measurements, although accurate, suffer of small biases in the estimates that lead to large long-term drift in the vehicle position and attitude estimates. This problem can be solved using a GPS. In many applications, however, GPS information is available for part of the mission, but may become lost, denied, or obscured for long periods of time, during which no position information is available. This loss of information could be the result of many causes such as flying indoors or in an urban canyon. In these situations vision information has the potential to provide relatively low-drift data from which to estimate vehicle ego-motion during GPS outages. Many of the causes of lost or intermittent GPS signals are physical obstructions such as buildings or mountains. In most situations where an object is blocking the GPS signal there are features for the camera to track. Situations with poor feature density include flying over the ocean or a desert or at high altitudes - all situations where GPS is likely to be available.

My primary contribution to the project was the realization and implementation of a Particle Filter and an Extended Kalman Filter for a vision-based navigation system integrating measurements from a suite of cameras, an IMU, and a GPS.
Great efforts were required for the realization of a C++ environment performing basic mathematical operations, filtering heterogeneous/ asynchronous measurements and interfacing sensors (IMU, GPS, cameras), allowing images processing and features tracking for vehicle ego-motion estimation.
