I will yet try to use Arduino servos if this solution proves too rugged or ineffective. That way I can exert control over the speed and power the device through a USB port.


Getting underway

Today I managed to thoroughly test the Kinect and everything seems OK.

I couldn’t resist setting up a project and getting to know the libraries and the all-encompassing mess of inclusions it requires. After the customary headaches, I managed to get the PCL rolling and capturing a simple point cloud as you can see in the image caption (my first capture!). I also set-up a SVN repository for the coming weeks of work. Now I need to get used to a style of programming I’m not really comfortable with.



Today was an important day as I received some very helpful advice to get my work with 3D capture underway. This came from Bruno de Araujo, a PhD student at Instituto Superior Técnico (check out his page). He lent me some of his expertise around capture with Microsoft Kinect, the state of the art, about some of top names also working with 3D capture and about the device itself. I’ll write more about that soon as I follow up those threads.

Also today I received the Microsoft Kinect I will be working during this process from my research mentor, and didn’t lose much time following some of the advice I got from Bruno. This involved exploring the Point Cloud Library SDK which I promptly downloaded and proceeded to build along with its dependencies. The process took about 5 hours of grueling memory consumption and heavy processing during which I took upon myself to update the blog. Rarely have I seen my laptop struggling so much with anything. Auspicious start it is!

I expect tomorrow to have everything working so I can run some tests on the Kinect.

Also I added a couple links to the blogroll on the right. One of them is the 3DORuS program where my project is inserted. The other is a similar blog from a fellow colleague which will be working on Model Retrieval for the LTouchIt project.

What is this blog…

… And why am I wasting time with it?

As a MSc student in Information Systems and Computer Engineering by Instituto Superior Técnico, I am currently working on my Master’s thesis on the same area. This blog’s mission is precisely to track and log my progress with my work for the following year.

The thesis work itself, can be described perfectly by the following paragraph, which I so appreciatively copied from the research position proposal, as written by my research mentor, Alfredo Ferreira, PhD and Assistant Professor at Instituto Superior Técnico:

“Develop a 3D object benchmark, captured with a low cost depth sensing camera, such as Microsoft Kinect. This benchmark will be submitted as a new track to the Shape Retrieval Contest (SHREC) 2013. Assuming this track will be accepted by contest organizers, this workplan might be extended to also include the processing and analysis of the contest results. This work has a potential of great visibility among the scientific community.”

So that’s it. I’ll be posting news as fast as required and my work ethics permit. Stay tuned!
