Cool thing. But didn't you forget the instability of the plane around the pitch axix?

Chris Anderson

Not forgotten at all, just not solved yet! Although in practice the tilting problem is much worse along the roll axis (which we have solved) than the pitch axis. That's because the plane doesn't have to pitch to turn and it's inherently more stable along that axis because of the conventional wing-and-elevator configuration (a flying wing would be tougher).

Also, the good thing about any instability around the pitch axis is that it leads to tilting that's along the path of the plane. So when the software tries to stitch the images together to make the strips that we mosaic to create an overhead map, it can at least find feature overlaps from adjacent images, even if they've been pitch tilted (they're either where we're going to be shortly or where we've just been). That's not the case if they've been roll tilted, since those images tend to be off to one side or the other.

Make sense?

You might want to try disassembling the camera, to get at the shutter release circuit. In most cameras, it's a 2 position switch - position 1 is auto focus, position 2 triggers the shutter. This way, you can fire it with either 1 or 2 channels, ditch the servos, and gain weight capacity and servos for the other gyro axis.

Chris,

There are also software solutions for registration of data that have not been taken at precise orthogonal positions, altitude, latitude/longditude etc.... Send me some of your image data and I'll register them for you to illustrate.

Really nice, your creativity and the attitude of trying new things is highly appreciable. Hope it is working well, I'm really expecting some big project from you.I strongly believe you can...

That's cool, but why not just use a big kite? That's what I've done and it works like a charm.
