The invention discloses a
vehicle positioning method and a vehicle finding method in a
parking lot. The
vehicle positioning method comprises the following steps: acquiring the position of the entrance of the
parking lot through a GPS of a mobile terminal before a vehicle enters the
parking lot; after the vehicle enters the parking lot, acquiring the traveling track of the vehicle through an
inertia measurement device of the mobile terminal; when detecting the advancing state changes from a travelling stage to a walking stage, by using the
inertia measurement device of the mobile terminal after the vehicle is parked,, at the moment, calculating the parking position according to the position of the entrance of the parking lot and the traveling track through the mobile terminal, and recording the parking position. The vehicle finding method in the parking lot comprises the
vehicle positioning method as well as the following steps: when a user finds the vehicle, acquiring the present position of the user through the GPS and / or manual input through the mobile terminal; generating a vehicle finding
route from the present position of the user to the parking position through the mobile terminal, and guiding the user to find the parking position according to the vehicle finding
route. The vehicle positioning method and the vehicle finding method in the parking lot are low in cost, high in practicability, high in feasibility and easy to popularize.
