System, method and application for estimating pneumatic pressure state of vehicle tires using a handheld device
First Claim
1. A system for estimating pneumatic pressure state of vehicle tires using a handheld device having at least one camera installed therein, said system comprising:
- an image acquisition module configured for allowing a user to acquire an image of a vehicle wheel, using the camera and image acquisition functionality of the handheld device, said acquiring comprising;
(i) iteratively, based on a video stream received from said camera;
(1) analyzing a frame of the video, to determine (a) an orientation between an axis of said at least one of wheel and a focal axis of said camera, (b) a center distance of said at least one wheel in the frame, and (c) whether the frame contains a complete wheel capture,(2) presenting a marking on a display of said handheld device, the marking instructing the user of said handheld device to turn said handheld device for said acquiring, and(ii) acquiring said image when said orientation is substantially coaxial and said at least one wheel is substantially centered in said frame;
an image analysis module configured for receiving said image from said image acquisition module and analyzing said image for estimating the pneumatic pressure state of a tire of the wheel in said image; and
a presentation module for presenting the estimated pneumatic pressure state of the tire via said display of said handheld device.

Abstract
System method and computer operable application for estimating pneumatic pressure in tires of vehicles, using a handheld device having at least one camera installed therein that allow acquiring an image of a wheel of a vehicle, using the camera of the handheld device, analyzing the acquired image for estimating value of at least one parameter of the tire of the wheel in the image, where the parameter is related to pneumatic pressure of the tire, estimating pneumatic pressure state of the respective tire by using the parameter and presenting an indication of the estimated pneumatic pressure state.
