A method of leveling an elevator car, a projection device and a leveling system. The method of leveling an elevator car includes: stopping the elevator car on a set landing; generating a calibration image that spans across the base plane of the elevator car and the base plane of the landing; processing the calibration image, and determining whether the elevator car is leveled with the landing based on the calibration image processing result; and ascending or descending the elevator car when it is determined that the elevator car is not leveled with the landing. According to the leveling method of the present application, it is possible to quickly and easily identify whether the object to be leveled is leveled with the leveling reference by analyzing and processing the calibration image, and even further identify the degree of levering, thereby realizing quick and simple leveling.
