vision system design using 2 Basler line scan cameras

[Jack H]

I would like to use 2 Basler line scan cameras (models L100 or L200) that I checked on the NI site as being approved. I would like to know how to acquire image data from 2 cameras at the same time and log this to the computer database.This is a high speed web application.

Jack,

You shouldn't have any problem. You will need to use two PCI-1422 or PCI-1424 cards, since each card can only handle a single camera. You can use the RTSI bus to synchronize the two cameras. You will probably need an encoder for timing signals.

I am not sure what information you want to log to a database. If you are planning on storing the images, it could slow down your system, depending on the size of the images.

Bruce,

Thanks for the information. I am trying to develop a system to measure optical density of a web coating that runs at very high speeds - real time measurement. NI suggested the grayscale option, but I wanted to know about using multiple cameras to compare the web coating side to side.
