Abstract: Provided are an automatic parking method and system of a vehicle. The automatic parking method includes the steps of: taking an image of the surroundings of the vehicle and converting the captured image into a top view image; recognizing a parking space on the basis of the converted top view image; sensing obstacles in the parking space surroundings; detecting a first vehicle entry point and a second vehicle entry point in the parking space for parking the vehicle using information on the detected obstacles and information on a parking line in the parking space; and calculating a parking path of the vehicle using the first vehicle entry point and the second vehicle entry point which have been detected. A vehicle can be automatically parked by recognizing a parking space based on a top view image of the surroundings and detecting two vehicle entry points using obstacles in the surroundings.
