Abstract
An object tracking device includes a camera with a field of view oriented in a first direction and a mirror with a field of reflection oriented in a second direction. When an object is in a first region in the field of view of the electronic camera, the camera has a direct view of the object and a reflected view of the object from the mirror. A processor coupled with the camera is configured to receive a first image data set and a second image data set from the camera. The first image data set and the second image data set each include the direct view of the object and the reflected view of the object from the mirror.
