Function Documentation

void closeCamera

(

InstanceStore *

store

)

Close/release the camera and deallocate all used memory.

Parameters

Pointer to the store returned by initFeed() or initCamera().

InstanceStore* initCamera

(

int

camIndex

)

Starts the vision system with a USB camera.

Parameters

camIndex

Index of the camera to use.

Returns

InstanceStore for current vision system instance.

Note

See CamFeed::CamFeed(int camIndex) for details on camera indexes.

InstanceStore* initFeed

(

const char *

feedPath

)

Starts the vision system from a feed path.

Parameters

feedPath

URI of feed source.

Returns

InstanceStore for current vision system instance.

Note

See CamFeed::CamFeed(const char * feedPath) for details on URI specification.

LineResult processFrame

(

InstanceStore *

store

)

Process a new frame for vision.

Parameters

store

Pointer to the store returned by initFeed() or initCamera().

Returns

LineResult Output of vision system.

bool setThreshold	(	InstanceStore *	store,
		int	newThreshold
	)

Sets the thresholding cuttoff value.

If not run, the value will default to 234.

Parameters

store	Pointer to the store returned by initFeed() or initCamera().
newThreshold	The new threshold value - takes values 0-255 (inclusive).

Returns

true if operation was successful, false if newThreshold was invalid or if store is null.

Note

Try to have this as close to 255 as possible while still being able to detect the target reliably.
