Abstract
A method of unlocking a vehicle of a user having a handheld device based on visual domain and radio frequency (RF) domain technologies is provided. The method comprises activating an on-board apparatus of the vehicle when the handheld device of the user is within a threshold distance from the vehicle. The method further comprises comparing a visual domain position of the user based on visual domain data with an RF domain position of the user based on RF domain data by a first equation, |d(X)−d(X)|<εand a second equation, |φ(X)−φ(X)|<ε. The method further comprises validating the user when the first and second equations are true and unlocking the vehicle after the user is validated.
