A method and a system for determining the position of an elevator car of an elevator system, which car is arranged for travel in an elevator hoistway, includes equipping the elevator car with an acceleration sensor that registers acceleration data in a computing unit, calculation by the computing unit of the current position and/or of the velocity of the elevator car, and equipping the elevator system with an image-recording unit, which unit records recorded images of the elevator hoistway. The computing unit compares the recorded images with current mapping images of the elevator hoistway to determine an image-based current position of the elevator car. Finally, the computing unit undertakes a recalibration of the current position using the image-based current position.
