In this video, we present the first onboard perception system for 6-DOF localization during quadrotor high-speed maneuvers using a Dynamic Vision Sensor (DVS). Unlike a standard CMOS camera, a DVS does not wastefully send full image frames at a fixed frame rate. Conversely, similar to the human eye, it only transmits pixel-level brightness changes at the time they occur with microsecond resolution, thus, offering the possibility to create a perception pipeline whose latency is negligible compared to the dynamics of the robot. We exploit these characteristics to estimate the pose of a quadrotor with respect to a known pattern during high-speed maneuvers, such as flips, with rotational speeds up to 1,200 degrees per second. Our algorithm is completely event-based, that is, every event is used as it comes to update the pose of the robot.

Glossy reflections with +WebGL (and just now I've noticed that the ceiling is missing) http://youtu.be/xxHjMFsZZuk +three.js +JavaScript

Using parallax-corrected cube maps. Diffuse, normal and specular maps. Made with three.js for WebGL handling, custom shaders for rendering and Wagner for postprocessing (bloom, FXAA and vignette)

For those of you who are planning to attend ECCV in Zurich this week, I would like to draw your attention on the workshop "W02 – Computer Vision in Vehicle Technology with Special Session on Micro Aerial Vehicles" which I am co-organizing with David Geronimo and Friedrich Fraundorfer. The workshop will take place a ETH this Saurday. The afternoon session is dedicated to vision-controlled drones and will feature live demos including one from my lab on Live Dense 3D Reconstruction, using SVO and REMODE. Below, you can have a glance of it.
