Distance marker and mobile device case for distance measurement
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.
1. A case system for an electronic device having a camera, the case system comprising:
a compartment configured to retentively receive the electronic device;
a distance marker; and
a software application installed on the electronic device, wherein the software application is configured to determine a distance between a first location and a second location from a photographical image, taken by the electronic device at the second location, of the distance marker positioned at the first location.
2. The case system of claim 1 , wherein the distance marker is removably coupled within a pocket formed into the case system.
3. The case system of claim 1 , wherein the image comprises a sticker adhered to the distance marker.
4. The case system of claim 1 , wherein the distance marker comprises a magnet configured to magnetically couple the distance marker with the electronic device when the electronic device is operationally retentively received within the compartment.
5. The case system of claim 1 , wherein the distance marker comprises intersecting walls.
6. The case system of claim 1 , wherein the distance marker includes a magnetized element.
7. A method for measuring distance, the method comprising:
providing a case for an electronic device;
providing a distance marker having a tracking image, the distance marker being configured to be coupled to the case;
positioning the distance marker at a selected first location;
photographically capturing the image of the distance marker at a second location using the electronic device; and
analyzing the captured image using the electronic device to determine a distance between the first and second locations.
8. The method of claim 7 , further comprising:
attaching the distance marker to the case.
9. The method of claim 7 , further comprising:
displaying the distance to a user using the electronic device.
10. A method for measuring distance, the method comprising:
preparing a case configured to receive an electronic device, the case having a pocket configured to receive a distance marker;
installing a software application to the electronic device;
removing the distance marker and positioning the distance marker at a first location;
detecting an image associated with the distance marker at a second location using the electronic device; and
calculating a distance from the first location to the second location using the electronic device.
11. The method of claim 10 , further comprising:
displaying the distance to a user using the electronic device.
