Question

I am getting 3 camera input to MATLAB with Infinite Trigger. But after minutes, cameras fill up my memory, and I have to restart MATLAB. How can I deal with this memory problem?

Answer 1

Since your question is a little vague, I’m going to guess that you are using the Image Acquisition Tool from the Image Acquisition Toolbox to acquire images. If so, you should check out the documentation on logging your data. Here’s a screenshot of the Logging tab of the Acquisition Parameters Pane:

Notice that you have 3 options for logging data: Memory, Disk, or Disk and memory.

I’m guessing that you are doing Memory logging by default, meaning that the acquired images that you do not otherwise save will be logged to your system’s memory. There is a limit on the memory available. By default, the tool sets the limit to equal all available physical memory when you first use the tool, or 1 GB, whichever is less.

You have two options that I can see:

• You may be able to set the Memory limit to be higher in the above GUI (assuming it is defaulting to the smaller value of 1 GB, and you actually have more memory available than that). I would try that first and see if it helps at all.

• You can use the Disk logging option to instead log your images to disk as an AVI file. This will give you the option to compress your images and reduce the amount of space they take up.
