I had a similar problem while trying to put together a motion capture system last year. I ended up addressing it by replacing the stock lenses with S-mount (also known as M12) board lenses, and made new enclosures for the cameras out of layers of laser-cut acrylic. A captured 1/4-20 flange nut allows for easy mounting on tripods or articulating camera mounts. There's a very good selection of lenses in this form factor (including varifocal and motorized varifocal).
I could build a few more if anybody is interested. I made two versions, one for the Playstation Eye camera (640x480 @ 60fps uncompressed) and the other for the Logitech C920 camera (1920x1080 @ 5fps uncompressed [30fps compressed]). http://imageshack.com/scaled/1024x768/708/6eu3.jpg http://imageshack.com/scaled/1024x768/9/t71e.jpg > David Armstrong <mailto:dave...@outlook.com> > Friday, November 08, 2013 11:35 AM > > i presume your looking for camunits git , here it is . > > git://psha.org.ru/psha/camunits.git > > > ------------------------------------------------------------------------------ > November Webinars for C, C++, Fortran Developers > Accelerate application performance with scalable programming models. > Explore > techniques for threading, error checking, porting, and tuning.
