Internship proposal : « Visual-Odometry for Autonomous Vehicles based on RGB-D-T cameras »

Visual-Odometry (VO) is the main perception task for a robot in order to estimate incrementally its 3D motion using 2D image sequences. VO is often associated with 3D reconstruction aswell as localization thus allowing the robot to understand its surrounding environment and locating itself (position and attitude) in a continuous manner and in real-time.

In this internship project, we propose a VO task that could take a benefit from all the advantages
of various visual sensors, a conventional camera (RGB), a depth camera (D), and an Infra-Red camera (T), in a continuous-time sensor fusion framework as illustrated in Fig. 1.

More precisely, the main task is to study continuous-time camera trajectory optimization using highly efficient B-splines as in [2, 3] and IR camera (T) features extraction and investigate the methods to integrate them in the same B-spline optimization function for the RGB-D
camera frames modeled in [4, 5]. Some novel works dealt with this problem using discrete time
particle filters as in [6].

Our goal is to integrate this RGB-D-T continuous-time B-spline trajectory as a real-time map into a complete heterogeneous vision system (RGB-D-T + DAVIS sensor). Accordingly, this RGB-D-T map is supposed to be very accurate, fast (continuous-time) and robust for all
challenging environments. The intern student will work closely with a PhD student, as well as the professors involved
in the project.


1. Solid background in Computer vision and Optimization.
2. Good understanding of thermal sensors features extraction and matching
3. Good skills in programming
4. Highly motivated and results oriented.
