A system and method to detect speed of subject(s) utilizing a camera from any device (i.e. mobile, tablet, camera, computer, etc.) to capture moving subject distance, fixed object distance, and time using other video/photos taken by user(s) to calculate speed for comparison is disclosed.

Device Meta Data Capture for Speed Calculation
Disclosed is a system and method to detect speed of subject(s) utilizing a camera from any device (i.e. mobile, tablet, camera, computer, etc.) to capture moving subject distance, fixed object distance, and time using other video/photos taken by user(s) to calculate speed for comparison.
Existing technologies require specific devices with the primary objective of measuring speed. The disclosed system allows users to measure / calculate speed from video/photos taken using any device and/or multiple devices, where the required metadata is gathered and the system allows the user to identify the moving subject(s) and a fixed background object(s) subject(s). Currently only high end digital lenses allow subject distance to be recorded. As camera technology continues to advance, the accuracy of the metadata is expected to improve significantly. It is expected that this technology will become more pervasive.
The Figure below depicts a workflow:
User(s) positions camera toward moving subject(s) AND a fixed object
in the background(s) that will NOT be moving (i.e. a tree, building, etc.).
Objection selection could be based on --
Dynamic (target any moving subjects on the screen and
tag for later selection).
Manual (user touches or selects) subject of choice.
Predefined by showing photo or documentation that
describe what subject should be targeted.
Fixed object would be utilized to validate distance changes and compensate for any movements of the camera -- for example, if the user follows the moving subject with the camera, the distance change would be calculated from the fixed object.
Camera captures (either using video or photos or live feed) the
