Object position measurement with automotive camera using vehicle motion data
First Claim
1. A method of locating a position of an object with an omnidirectional camera affixed to a vehicle, the method comprising:
- receiving movement data of the vehicle from vehicle sensors indicative of a change of position of the vehicle;
receiving a plurality of omnidirectional image frames of one or more stationary objects with an omnidirectional camera;
identifying an object of interest from the one or more stationary objects in the omnidirectional image frames,tracking the object of interest in the omnidirectional image frames, with an electronic control unit, while the vehicle is moving;
determining a change in position of the object of interest in the omnidirectional image frames as the vehicle is moving; and
determining a distance to the object of interest relative to the vehicle based on the change of position of the vehicle and the change in position of the object of interest in the omnidirectional image frames.

Abstract
A method and system of locating a position of an object with an omnidirectional camera affixed to a vehicle. An electronic control unit receives movement data of the vehicle from a vehicle communication bus. Simultaneously, the electronic control unit receives a plurality of omnidirectional image frames of a stationary object with the omnidirectional camera. Based on the received omnidirectional image frames, the electronic control unit identifies an object of interest in the omnidirectional image frames and tracks the object of interest in the omnidirectional image frames while the vehicle is moving. The electronic control unit determines a change in position of the object of interest in the omnidirectional image frames as the vehicle is moving and determines a distance to the object of interest based on the change of position of the vehicle and the change in position of the object of interest in the omnidirectional image frames.

15. An object locating system for locating a position of an object with an omnidirectional camera affixed to a vehicle, the system comprising:
-
at least one vehicle sensor configured to indicate a change of position of the vehicle; an omnidirectional camera; a user interface configured to display video information to a driver of the vehicle; and
an electronic control unit configured toreceive a plurality of omnidirectional image frames from the omnidirectional camera including an omnidirectional image of a one or more stationary objects, receive movement data of the vehicle from the at least one vehicle sensor indicative of a change of position of the vehicle; identifying an object of interest from the one or more stationary objects in the omnidirectional image frames, tracking the object of interest in the plurality of omnidirectional image frames while the vehicle is moving; determining a change in position of the object of interest in the omnidirectional image frames as the vehicle is moving; and determining a distance to the object of interest based on the change of position of the vehicle and the change in position of the object of interest in the omnidirectional image frames. - View Dependent Claims (16, 17, 18, 19, 20)
