Abstract: A method for determining estimated real dimensions of an elevator car by: acquiring a virtual 2-dimensional map of the car based on data provided by a lidar sensor, the map representing reflection surfaces from which laser light emitted by the sensor is reflected; defining a rectangular starting area at a position located within the real dimensions of the car; successively extending the area by one pixel in each of four extension directions orthogonal to edges of the area, and when any pixel in one of the extension directions corresponds to one of the reflection surfaces in the map, stopping extending the area in this extension direction and successively extending the area by one pixel in each of the remaining extension directions the area is extended to a maximum in all the extension directions; and determining the fully extended rectangular area as the estimated real dimensions of the car.
