Hey @rawatrob,
the camera opens automatically when you use the plugin on your app. Just add

<preference name="backgroundColor" value="0x00000000" />

to your Cordova config.xml and on your CSS set the body background to transparent.
There's no function to open or to close the camera using JS implemented if that's what you wanted.
To detect a target image you first need to set it using the function setPatterns provided by the plugin, then use the isDetecting function to know when a image is being detected. Check the usage example to see how this can be done.
