@Electro the getUint16LittleEndian method is used for reading 16-bit integers from the Camera. It's used for reading the camera's configuration/settings. See this search for the getUint16LittleEndian method on the tau camera github repo for details of when it's used. For your purposes of finding the closest point in the frame, you should look at the readFrame method. It will return a Frame object with distance/depth. See the related documentation entry for more info. You can see the readFrame method in action, as well as how OpenCV is used to render pictures using the data in the example programs. Enjoy!
