Intro to Vuforia

Vuforia is a library often used with vision detection for FTC. To use Vuforia, you will need to obtain a Vuforia license key. Luckily, this process is simple and steps can be found here.

Instantiating Vuforia​

Once you have gotten the license key, you must start the initialization of Vuforia. Start with these two lines.

String VUFORIA_KEY = "Vuforia Key Goes Here"
VuforiaLocalizer vuforia;

Parameters​

Now we must further initialize the Vuforia Engine but passing the necessary parameters for it to run. Just paste this line into your initialization.

int cameraMonitorViewId = hardwareMap.appContext.getResources().getIdentifier("cameraMonitorViewId", "id", hardwareMap.appContext.getPackageName());
VuforiaLocalizer.Parameters parameters = new VuforiaLocalizer.Parameters(cameraMonitorViewId);

Now we since we have created the parameters object, we can pass in the actual parameters.

parameters.vuforiaLicenseKey = VUFORIA_KEY;
parameters.cameraDirection = BACK; //Making sure to use the right camera

Paste these lines to pass everything into and actually startup the Vuforia Engine

vuforia = ClassFactory.getInstance().createVuforia(parameters);

vuforia.setFrameQueueCapacity(1);

vuforia.enableConvertFrameToBitmap();
