Pan/tilt controller with center on click

Jan 08, 2007 5 Replies

I'm looking for a pan/tilt controller that has the feature to center the camera on a mouse click of the video feed.



I'm not sure if they make one, but I know certain PTZ cameras (like the Sony SNC-RZ30) have this feature, where, on the live video feed, you click, and the PT moves the camera to center the video on the spot you've clicked on. You can then zoom and re-center by clicking again. It makes panning and tilting very convenient.



I haven't been able to find a controller with this feature. Does anyone know where I might find one? Or where I may start? Or possibly, what this technology is called? I'm having the most trouble searching for it because I don't know what it is called, exactly.



Thanks for any help.



A: What a cool notion! I'm going to forward this mail to some marketing folks I know, so they can tell me "well duh, we've been asking you engineering folks to build this for years" (that's just how they react to suggestions).

B: I dunno. Given a camera that reports it's field of view relatively well, and a platform that can be position servoed, this should be pretty easy to do in application software. On a PC it should be a piece of cake for the folks doing the interface application.

C: If you find one, could you please post your result here? Thanks.

I'd be inclined to use some IG3085TS-WXc steppers mounted in your assembly for X-Y control fed via a T104XG USB sub interface controller and an IR43RCS power micro-stepping interface module.

There is a better than average chance that you could almost get away with a similar system for the focussing (Z-axis) stuff but you probably will need to use the extra 32 bit precision from the IG3085TS-WXf and an IR43RCS/C driver.

It might be nice but it is going to cost more.

You can download the demonstration PC/Embedded control software (Windows/Linux/BSD) from the manufacturers website and you also get lots of examples for most of the popular micro-controllers along with communications stacks.

What I was wondering is what system does he want:

Click on point, and have the camera move that to the center. Or Click on object and have camera center it and follow.

The last case: you click on a car somewhere at the edge of view, and the camera brings it to centre and follows it.

Do I get the patent now? LOL

Tracking is not necessary. Centering only.

I'm also not trying to design the system, if possible. I certainly could, but for this application I am searching for COTS systems.

have a look at hawkeye stuff
