Distance marker and mobile device case for distance measurement

摘要

A mobile device case or cover can include a distance marker for distance measurement. A mobile device coupled with the case may include a measurement application or module that can acquire video or still images of the distance marker. The measurement application can calculate a distance to the distance marker based on a captured image of the distance marker in the video or still images. The mobile device case can include a pocket, slot, or storage compartment for storing the distance marker.
