You can connect to the camera board from the MATLAB® software, take a photograph, and record video.
Create a connection from the MATLAB software to the Raspberry Pi hardware.
mypi = raspi
Create a connection, mycam, from the MATLAB software to the camera board, and set the image resolution. The connection
displays the camera board properties.
mycam = cameraboard(mypi,'Resolution','1280x720')
mycam =

Import and display a sequence of 10 snapshots on your computer.
for ii = 1:10
img = snapshot(mycam)
imagesc(img)
drawnow
end
If the image is upside down, change its orientation.
mycam.Rotation = 180
You can use the same approach to change the values of other cameraboard
properties.
Record a 60 second video.
record(mycam,'myvideo.h264',60)
Stop the recording immediately.
stop(mycam)
Copy the video from the board to your computer.
getFile(mypi,'myvideo.h264','C:\MATLAB ')
Delete the video file from the hardware to free up space.
