okay you guys have got me involved in another project...
I have been reading all your posts about gyro drift and fixed reffrence points, to maintian the yaw and pitch center positions. I have some background with real aircraft gyros and Inertial navigation systems(INS). The key like you all are saying is the refrence pooint. INS especially the ones I work with require updates ocassinally to prevent massive drift errors. In the fullsize aircraft we used....to use a radio fix (tacan) mix, or a radar fix, to update the INS so it would not just be running off gyros.
Well I have been trying to think outside the "box" for a couple of days now. And here is what I have come up with. As a virtual pilot your body is always facing towards the aircraft nose(foward), correct? When you turn your head to look you are moving your head a certian number of degress diffrence in relation to the nose of the aircraft, correct? So what we need is to compare the heading in degrees from your head to the heading in degrees from the aircraft. So to keep it simple if we gave ourselves a referrence point that corrosponds to the aircraft nose, we will have our inital heading to derive the diffrence from. As RC pilots what is the one thing that is always pointing foward in relation to our head? Our TX!!! My idea is to used a compas module or gyro mounted in the trainer cord connector that is plugged into the TX. Then to put a compass module or gyro in the VR goggels. Now we get two headings for the PIC or the basic stamp(thats what I am familiar with), it can compute the diffrence and then turn the camera(pan) that many degress or a percentage of arc. For gyros you could compare the movement of one gryo to the other and use that to compute the amount of movement of the camera. What I see as the beauty of this idea is that when your head is facing foward both compass modules will read the same heading regardless if you spin your body around(to get out of the sun) as long as the two headings are the same, the amount of pan of the camera will be 0. Also if you have a pax headset they generally will be standing next to you facing the same dirrection(their body), so the computations would be the same. This is the system I am going to be working on now DAY AND NIGHT...I cant even sleep anymore.
I also have a simple idea for pitch..If I see intrest I will type it out.
