About my blog

Based on novel robot vision/image recognition algorithms, it is possible to reconstruct a 3D model with a simple webcam in real-time. The AR drone, equipped with several cameras seems to be a perfect match to establish a 3D scanning system for large objects, such as cars or buildings. (Experts: Ronald Poelman&Oytun Akman)

Cons:

– Still takes a lot of time (± 1.5 hour).

– The model still shows some deviations from the real model.

– The quality of the model depends on the lighting and the
reflections on the object to scan.

Repair and software research

Hi, it has been a while since our last
blog. The past few days we were very busy trying to get

the drone to fly properly. Last
Friday we went to the aula, and after a little bit of asking around, 

we had the chance to fly in one of the
college rooms.

We did this to practice flying with the drone and to make some
videos, that we can use later on to create a 3d model.

 

Last Monday we did some repair works
on the ARdrone. Because apparently someone had crashed

the drone before we received it from
Jouke Verlinden.

The drone was broken at the cross were the arms of the quadrocopter come
together.

First Menzo and Roeland tried to solve the problem by gluing the
parts together, this didn’t work.

Eventually we solved the problem
using two washers and 4 nuts and bolts.

Then we tested the drone again and
we could immediately notice the ARdrone was much more stable than before.

The rest of the time we did some research on software to get a 3d model from the videos taken last Friday.

 

Flying the Drone for the first time!

Today we were finally able to start flying the Drone.

We did have some hurdles to overcome. First of all, we were able to install the software for flying on a laptop. And indeed, the Drone started flying. However, we were not able  to control it’s flying through the laptop. This resulted in a rescue dive in order to stop the drone from randomly flying away. 

Secondly, we weren’t able to install the software on a phone using android. So we had to look for an iPhone we could use. Finally after 2 iPhones and a lot of instalations, we were able to finally FLY!

Pictures and movies will be uploaded asap. 

Quadrocopter movies

Here are some cool movies from a quadrocopter controlled by the "Kinect"

and from quadrocopters programmed to juggle a ball.
