Digital camera
Hi Sirs, I didn't replay to your questions because I was not at work.
I'm sorry beacause I realize that I was too criptic in my post.
The digital camera that I use is a : DALSA 1M-60 that has a CCD sensor
1024x1024 pixels and is capable to output 60 frame per second.
The output is converted (inside the camera) in a word 12 bits wide (this means that on the bus I need two bytes per sample).
As you can see the recording speed that I need is 120 MBytes per sec.
The lenght of the recording is about 20 minutes.
I don't think that this rec. speed can be managed on a normal PC (this i due to the limitation of the OpSys), I tried on a dual Pentium with to coreco frame grabber units but the maximum speed was about 12 frames per second (under win2000). There is one PC solution that I know: (see
https://www.conduant.com/) but its very expensive above 10K$.
I know that there are some military HD recording units that replaces the HDDT tapes for the recording of radar images, they use an array (8 units 75 Mbytes each) of seagate barracudas with fiber channel interface and it can reach about 140 MBytes per second. I have no other info on such units.
There is also military application for this camera for aerial reconoissance, that use barracudas and a VME? based computer.
I think that the hardware to perform this task exists.
My idea is to build a simple electrical interface from the LVDS output of the camera and the disk but I don't know how to perform a direct write on the HD.
Best wishes.
