MATLAB: Does the Image Acquisition Toolbox 1.0 (R13.0.1+) support simultaneous image capture from multiple cameras

Question

I also would like to know if the Image Acqusition Toolbox supports stereo vision.

Answer 1

The Image Acquisition Toolbox 1.0 (R13.0.1+) can perform simultaneous image capture from multiple cameras assuming:

- the hardware used is supported; and

- the hardware is configured to perform simultaneous capture

Most hardware will not allow you to acquire data from multiple sources simultaneously. This is a limitation imposed by the hardware, and not by the Image Acquisition Toolbox.

To work around this limitation you can use a frame grabber that supports color inputs, such as RGB. Connecting monochrome cameras to each of the R, G, and B inputs will enable you to:

- acquire data from each of the inputs; and

- then treat each band as a separate image

If you only need data from two cameras, data from the third input can be ignored. To ensure simultaneous capture, the cameras must be GENLOCKED (synchronized).

To perform simultaneous capture of color data, you must use two frame grabbers. The cameras must be triggered with hardware triggering, and again must also be GENLOCKED.
