Constructor Detail

Camera

public Camera(int index,
              boolean autoUpdate)

Creates a new Camera.

Parameters:

index - The ID of the Camera, 0-indexed. If there is only one Camera available, it should be ID 0.

autoUpdate - If this Camera should keep the frames served by Camera.getImage() up to date.

Method Detail

isUpdatingEnabled

public boolean isUpdatingEnabled()

Checks if the auto updating for this Camera is enabled. This is NOT used to check if the Camera is in auto updating mode. Use isAutoUpdating() for that.

Returns:

If the auto updating for this Camera is enabled.

setUpdatingEnabled

public void setUpdatingEnabled(boolean u)

Sets if the auto updating for this Camera is enabled.

Parameters:

u - The new status of the auto updating.

isOpen

public boolean isOpen()

Checks if this Camera is open.

Returns:

If this Camera is open.

isAutoUpdating

public boolean isAutoUpdating()

Checks if this Camera is auto updating its frames.

Returns:

If this Camera is auto updating its frames.

onEachFrame

public void onEachFrame(java.util.function.Consumer<Image> c)

Sets the code that runs every time a frame is processed. Set this to null if you want no code to run.

Parameters:

c - The code to be run.

getImage

public Image getImage()

Gets the current Image on this Camera.

Returns:

The current Image on this Camera.

open

public void open()

Opens this Camera.

release

public void release()

Releases this Camera.

getFPS

public double getFPS()

Gets the FPS of this Camera.

Returns:

The FPS of this Camera.

setFPS

public boolean setFPS(double d)

Sets the FPS of this Camera. TODO: Figure out why this doesn't work. This should help: http://stackoverflow.com/questions/7039575/how-to-set-camera-fps-in-opencv-cv-cap-prop-fps-is-a-fake

Parameters:

d - The new FPS.

Returns:

If the operation was successful.

getExposure

public double getExposure()

Gets the exposure of this Camera.

Returns:

The exposure of this Camera.

setExposure

public boolean setExposure(double d)

Sets the exposure of this Camera.

Parameters:

d - The new exposure.

Returns:

If the operation was successful.

getRaw

public double getRaw(int propid)

Gets the value of an OpenCV property.

Parameters:

propid - The property ID. Should be a variable defined in Videoio.

Returns:

The value of an OpenCV property.

setRaw

public boolean setRaw(int propid,
                      double val)

Sets the value of an OpenCV property.

Parameters:

propid - The property ID. Should be a variable defined in Videoio.

val - The value to set the property to.
