The IP.com Prior Art Database
A self-calibrating optical device and a method for measuring dimensions of one or more objects is disclosed. The method utilizes SONAR (SOund Navigation And Ranging) to approximate distance of an object from the optical device. The method calculates the dimensions of the object using an image of the object captured using the optical device and the viewing angle of the lens (α).

Calibrating Optical Device for Measuring Dimensions of Objects Using SONAR
Disclosed is a self-calibrating optical device for obtaining dimensions of one or more objects using SONAR. The device utilizes one or more components such as, but not limited to, a 3-axis accelerometer, a gyroscope, a compass, a multi-axis motion sensor, a microphone, a speaker and a camera to obtain the dimensions of at least one of the one or more objects. In an embodiment, the device is one of, but not limited to, a smartphone, a tablet and a touch-enabled device.
In an exemplary implementation of the method disclosed herein, the self-calibrating optical device is placed on the surface of the object for calibrating the optical device to zero. In an embodiment, to initiate the action of calibration a user has to click/press a button on the optical device. Subsequently, the optical device is moved away from the object in parallel, to obtain a view of the object via an image capturing means such as, but not limited to, a camera. In an embodiment, state of the art components such as, but not limited to, a 3-axis accelerometer, a gyroscope, a compass and a multi-axis motion sensor fusion can be used to ensure that the optical device is parallel to object. Thereafter, the speaker and the microphone are utilized to approximate distance of the object using SONAR. Finally, using the image obtained via the image capturi...
