Visually tracking an LED at 1200 Hz using a Centeye neuromorphic vision chip and a Teensy 4.0

Inspired by recent fantastic work showing event-based cameras detecting fast moving objects, I decided to try something similar with one of Centeye’s vision chips. Our vision chips aren’t event-based, but they do have flexible acuity and direct pixel addressing functions which can provide some similar benefits (logarithmic response and dynamic allocation of pixel sampling). This …

Drone Obstacle Avoidance and Autonomy in the 2020’s- Diverse Needs and No Single Solution

Drone Obstacle Avoidance and Autonomy in the 2020’s- Diverse Needs and No Single Solution In my last article I told a story from the early 2000s about how we first integrated obstacle avoidance on a small drone. To recap, we were attempting to provide a fixed-wing model aircraft with a set of optical flow sensors …

Artificial insect intelligence and vision for nano drones – how many pixels do you actually need?

Artificial insect intelligence and vision for nano drones – how many pixels do you actually need? My long-time interest has been in developing insect-type vision for small drones. Properly implemented, I believe that such vision hardware and algorithms will allow small drones to fly safely amidst clutter and obstacles. Of course, I have been following …

Centeye Prototypes 360 Degree Stereo Vision System for Nano Drones

As part of an Air Force funded project, Centeye has prototyped a vision based system to allow small drones to both hover in place without GPS and visually detect nearby objects to avoid collisions. The video below shows sample flights in an indoor residence, taken in November 2015. A more detailed write-up is available on …
