Abstract: The invention relates to a method for triggering an acquisition of image data of an empty elevator car. The method comprises obtaining door status data representing a status of the door of the elevator car, obtaining occupancy status data representing an occupancy status of the elevator car, detecting based on the obtained door status data that the door of the elevator car is closed, detecting based on the obtained occupancy status data that the elevator car is empty, and generating a control signal to an imaging device arranged inside the elevator car in response to the detecting that the door of the elevator car is closed and the elevator car is empty. The control signal comprises an instruction to trigger the acquisition of the image data of the empty elevator car. The invention relates also to a triggering system for triggering an acquisition of image data of an empty elevator car and to an elevator system comprising a triggering system.

Abstract: A sensor for sensing a fill level of a space includes a housing, a circuit board, a camera, a distance measuring sensor and a controller. The controller is in communication connection with the camera and the distance measuring sensor to calculate the fill level of a space according to the input from the camera and the distance measuring sensor. An elevator includes the sensor for sensing the fill level of the elevator car space. A method for sensing and determining a fill level of a space like an elevator car without utilizing the gravity load can better identify the objects in the space and further calculate the fill level of the space according to the identified images, and can be used as a substitute or a beneficial supplement for gravity load determination.
