Hi Dan, Thanks for getting back to me. I am a software developer for Sandia National Labs robotics center and I am interested in using the pyro cameras on some of our mobile robots, as well as using them in lab environments. >What applications are you interested in? Do you want to record to disk >or videoconference over the net? Basically I'm interested in doing real-time user interfaces that use multiple cameras. Think of unencumbered/uninstrumented passive tracking of major body parts. I am really interested in gaming interfaces, but the folks at work want me to build other stuff, like sensors for people tracking in robot workcells or on mobile bots. So, I won't be going to disk, but will instead be using images captured synchronously to determine some 3D info regarding position/orientation and gesture of hands, head, arms, etc.. I'm looking to use 3-4 cameras simultaneously, which I've been doing with multiple PCI framegrabber boards & standard NTSC cameras. I want to go to 1394 because the cost is lower, and the signal is higher quality. > Can't help you here. Is it OHCI compliant? Do you know what chipset it > uses? It might be visible on the card, or run lspci. here are the specs for their basicDV board: PYRO Board: PYRO: 1394a compliant OHCI Isochronous and asynchronous data transfer Hot plugging 1394 Ports: 3 ports (2 external, 1 internal) Connectors: 6 Pin 1394 Bus Speeds: 100, 200, 400 Mb/sec. Bus Interface: PCI 2.1 compliant with Bus Mastering Board Size: 5? long x 3.2? high (13 cm x 8 cm high) IRQ: An IRQ is required. IRQ can be shared if motherboard provides this capability through PCI steering. # of Devices: Connect up to 63 1394 devices to PYRO. Connect to Digital camcorders, 1394 storage devices (hard drives, CD-ROM, CD-RW), scanners, speakers, etc. Looks good, che no? > I'm going to buy this dude too! better hurry. they're going like hotcakes. $129. > The writer of video1394 and some others on the devel list are using > uncompressed cameras for machine vision applications, so there is work > being done.

Thanks, Dan |
