You can add a USB camera to an NVIDIA Jetson™ platform and connect to the camera from the MATLAB® software to capture images.

To create a live hardware connection object, provide the host name or IP address, user name, and password of the target board.

hwObj = jetson('jetson-board-name','ubuntu','ubuntu');

To display a list of USB cameras connected to the Jetson board, check the webcamlist property of thehwObj object.

To update the list of the cameras connected to the board, connect a USB camera to the target and run the updatePeripheralInfo function.

updatePeripheralInfo(hwObj); hwObj.webcamlist
