stop
Stop recording from camera board or selected camera on ArduCam Multi Camera Adapter Module
Add-On Required: This feature requires the MATLAB Support Package for Raspberry Pi Hardware add-on.
Description
Examples
Capture Images from the Camera Board
Create a connection from the MATLAB® to the Raspberry Pi® board. If you encounter errors after running the above command, try using
additional arguments (as listed in raspi
) or refer to Troubleshoot Connecting Issues to Raspberry Pi Hardware.
mypi = raspi;
Create a connection, mycam
, from the MATLAB software to the camera board on the Raspberry Pi hardware, and set the image
resolution. The connection displays the camera board properties.
mycam = cameraboard(mypi,"Resolution","1280x720")
mycam = Cameraboard with Properties: Name: Camera Board Resolution: "1280x720" (View available resolutions) Quality: 10 (1 to 100) Rotation: 0 (0 or 180) HorizontalFlip: 0 VerticalFlip: 0 FrameRate: 30 (2 to 90) Recording: 0 Picture Settings Brightness: 50 (0 to 100) Contrast: 0 (-100 to 100) Saturation: 0 (-100 to 100) Sharpness: 0 (-100 to 100) Exposure and AWB ExposureMode: "normal" (View available exposure modes) ExposureCompensation: 0 (-10 to 10) AWBMode: "indoor" (View available AWB modes) MeteringMode: "average" (View available metering modes) Effects ROI: [0.00 0.00 1.00 1.00] (0.0 to 1.0 [top, left, width, height])
Capture and display a sequence of 10 snapshots on your computer.
for ii = 1:10 img = snapshot(mycam); imagesc(img) drawnow end
Each of the 10 snapshots is the latest image captured by the camera.
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.
deleteFile(mypi,"myvideo.h264")
Stop Recording from ArduCam Multi Camera Adapter Module Camera
Create a connection from the MATLAB to the Raspberry Pi board. If you encounter errors after
running the above command, try using additional
arguments (as listed in raspi
) or refer
to Troubleshoot Connecting Issues to Raspberry Pi Hardware.
mypi = raspi;
Create a connection from MATLAB to the ArduCam module attached to the Raspberry Pi board. Set the image resolution. The connection displays the ArduCam properties.
aCamObj = arducam(mypi,"MultiCamAdapter","Resolution","1280x720") selectCamera("Camera B");
aCamObj = ArduCam with Properties: ModuleName: "Multi Camera Adapter" SelectedCamera: "Camera B" Resolution: "1280x720" (View available resolutions) Recording: 0
Record a 10-second video.
record(aCamObj,"myvideocamB.h264",10);
Stop the recording.
stop(aCamObj);
Input Arguments
mycamera
— Connection to Camera Board
cameraboard
object
Connection to camera board on the Raspberry Pi hardware, specified as a
cameraboard
object.
Example: mycam
aCamObj
— Connection to camera on ArduCam Multi Camera Adapter Module
connection
Connection to a camera on ArduCam Multi Camera Adapter Module, specified as an arducam object.
Use the arducam
to create this
connection.
