The DAVIS camera developed by the Sensors group provides sparse, quick, high dynamic range events signaling brightness changes as well as global-shutter synchronous active pixel sensor (APS) image frames that can be triggered and captured on demand. It also integrates an inertial measurement unit that provides a vestibular rotation and acceleration sensing. These characteristics make it potentially useful for mobile robotics, but so far the USB2.0 camera is a bit too bulky and it provides limited on-board computing. The developments of smartphones have made available powerful application processors (APs). During my PhD, I designed a powerful event camera platform featured with a Xilinx Zynq FPGA. I implemented Optical flow and corner detection algorithms on it. This camera is called EDFLOW.


EDFLOW will be an ideal platform for application in Micro Air Vehicle (MAVs) which are starting to be used in many commercial applications. I will next use EDFLOW to develop and test algorithms for visual odometry (VOD) and simultaneous localization and mapping (SLAM). By using the EDFLOW, we aim to demonstrate order of magnitude improvements in computational cost and speed.
