Apparatus to hold wiimotes - pending. (Needed to wait for paycheck)

Decide on a 3d environment to use - I have done some research, and I believe the 3d portion of my project will use Microsoft XNA, as it is what most people appear to use for 3d environments with C#.NET

Here are the screenshots and pictures that I promised.

The first picture is of my IR light source. Right now I am just using the remote control that came with my laptop, it works adequately, but since it pulses the light, and is not very powerful, I will need to create an IR wand soon.

Here is the Wiimote setup. Without a solid apparatus to hold them, they can swivel,and rock back and forth, making data collection almost meaningless.  But it works fine as a proof of concept.

Here is the screenshot of my program in development. Please click on it to view full sized, as some detail is lost in the compression.

Some ideas and some progress

I was able to create a simple program that used the IR cameras from two wiimotes to determine the relative distance of a light source. This program also combines the two images to agree on a single x and y value for the light source. Screenshots will be added later.

I attempted to make an IR "light-wand" out of an LED flashlight and an IR LED. Attempted. It turns out that the LED that I chose required more power than the one that was originally in the flashlight. So I will either have to find a lower power LED or find a different board to solder this one onto.

My goals for this next week are to make a working IR wand and to compare ΔZ_real with ΔZ_relative with the wiimotes at a fixed distance to be determined later.

Goals For Sept. 16

In yesterday's meeting, two goals were set for next week.

1. Work out the geometic equations for stereoscopic vision

2. Write a small program to test these equations with real input.

Already I can tell that the math is going to be harder than I thought.

Update: The math is not hard. It's the opposite of hard. Easy.  That's a relief.

Introduction

This blog will be used to catalog the goals and milestones of my independent study to create a 3D tracking system using Nintendo Wiimotes
