Processing Wiimote Data

SENSORBAR_WIDTH of 19.30 worked for me :)

Nice job! Could you please share the source or at least describe the distance calculation algorithm?

It's pretty simple:

const SENSORBAR_MAGIC = 1389.4621; //Magic value ;)

const SENSORBAR_WIDTH = 12.07; //Distance between the LEDs in mm

distx = ir2.X - ir1.X;

disty = ir2.Y - ir1.Y;

distance = (SENSORBAR_MAGIC * SENSORBAR_WIDTH) / Math.Sqrt(distx * distx + disty * disty);

@hownottobeseen

what exactly is the SENSORBAR_MAGIC value?

[hownottobeseen]

@Elimentz09 I actually can't say it exactly.

I just measured the real distance between the sensorbar and wiimote and got that "magic" number. You sure can calculate that number with the size, resolution and focal length of the camera but hey, it's just a toy ;-)
