Hi,

The possible reason you do not see your camera might be that it is not a UVC compliant webcam. The Camera Calibrator App works only with cameras (UVC compliant webcams) supported by "MATLAB Support Package for USB Webcams", which is in base MATLAB. It does not require Image Acquisition Toolbox. Some UVC compliant webcams would also work with Image Acquisition Toolbox (OS Generic support package), but not the other way around. You can check the following documentation links for more information:

To further clarify, the list of visible cameras for the Camera Calibrator app is generated using the MATLAB Support Package for USB Webcams. The "webcamlist" function is used in particular and it only looks for UVC compliant cameras. For more information on "webcamlist" function, you can check the following documentation:

I hope it answers your query.
