The safety of autonomous\connected vehicles primarily relies on their ability to accurately sense the environment. The sensing problem is significantly challenging in weather conditions which include sudden change in lighting, smoke, fog, snow, and rain. Therefore, accurate sensing in adverse weather conditions is a critical and important safety problem that needs to be solved for any successful deployment of autonomous vehicles. There is currently no single sensor currently available in the market that can handle all the possible performance aspects and adverse weather conditions. The objective of this project is to use a combination of Radars and FIR cameras in addition to a LIDAR based system to map the environment and localize the vehicle with respect to the lanes on the road. This project will develop a prototype of an all weather sensing and localization system which will be useful for any autonomous or connected vehicle. The performance of the developed system will be corroborated with several data sets collected at Rellis. Demonstrations of the developed technology will also be done at the yearly Automated Vehicle Symposium, and SAE conferences.
- Developed a panoramic thermal camera system that provides a video with a 190-degree field of view.
- Developed an object detection system to identify cars and pedestrians from thermal sensor data. Consequently, implemented a sensor fusion algorithm to combine this with radar data for object tracking.
- Validated the system with high-fidelity simulations using Unreal Engine as well as with a high-resolution lidar.

Abhay Singh served as a judge for the Texas Junior Academy of Science (TJAS) in October 2021, which involved high school students from across the state.
Vegamoor participated in the ENDEAVR (Envisioning the Neo-traditional Development by Embracing Autonomous Vehicles Realm) non-profit event organized in Nolanville, TX on February 1, 2020. A prototype of the sensor fusion system was demonstrated, and rides were given to the residents inside the car. The public was also educated about the capabilities of autonomous vehicles.

This project was used as part of the research statement by one of the students (Vamsi Vegamoor) for applying to the Dwight D. Eisenhower Transportation fellowship from Federal Highway Administration (US Dept. of Transportation). The fellowship was awarded for the year 2020 and renewed for 2021.
All the data collected in this project have been uploaded in the VTTI Dataverse. The code used for the sensor fusion algorithm has also been made open-source and will be useful as a benchmark for future researchers.
Researchers discovered a gap in research related to vehicle detection in heavy rain/snow. This is a viable extension for this project but will require collecting data outside the state of Texas.
