    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.

    Abstract: A method for controlling a flight-capable drone in an elevator shaft of an elevator system uses an elevator system inspection arrangement configured for carrying out the method. The method comprises the following steps: receiving elevator shaft segment information provided by the elevator system that indicates which volume segment of the elevator shaft is currently designated to be off-limits for the drone; and controlling the drone along a flight path automatically determined by the drone, wherein the drone determines the flight path such that the drone travels exclusively outside of the volume segment designated as off-limits for the drone, wherein the drone determines the flight path taking into account the received elevator shaft segment information. By exchanging the elevator shaft segment information with the elevator system, the drone is able to initiate evasive maneuvers in good time in order to prevent collisions with fast-moving components of the elevator system.

    Abstract: A method and a device for monitoring characteristics of an elevator door motion procedure use a smart mobile device including multiple sensors. The method includes: (i) determining a time window, within which a door motion is assumed to occur, including a time interval enclosed by a start time limit and an end time limit and wherein at least one of the start time limit and the end time limit is determined based on first measurement values acquired by a first sensor in the smart mobile device; and (ii) detecting characteristics of the procedure based on second measurement values acquired during the time window by a second sensor in the smart mobile device. Using the method, door motion characteristics can be reliably monitored using a passenger's smart mobile phone while substantially limiting sensing and processing capacities required by the smart mobile phone as well as avoiding compromising passenger privacy requirements.
