摘要： According to one embodiment, an elevator passenger detection system comprises an image capturing unit, a detection area setting unit, and a detection processing unit. The image capturing unit captures an image in a predetermined range including a vicinity of a doorway at which a door is opened or closed, from an inside of a car. The detection area setting unit sets a detection area on a front return panel provided on at least one of sides of a doorway of the car, on the captured image obtained by the image capturing unit. The detection processing unit detects presence of a passenger or an object, based on the image in the detection area set by the detection area setting unit.

摘要： According to one embodiment, an elevator system includes a camera, a passenger detection module and a controller. The camera is capable of imaging a particular range in a direction from a vicinity of a door of a car to a hall when the car arrives at the hall. The passenger detection module detects presence or absence of a passenger who intends to get into the car by focusing on movement of a movable body within a specific area by using a plurality of time-series continuous images which are captured by the camera. The controller controls an opening/closing operation of the door based on a detection result of the passenger detection module. A width of the area is being set greater than at least a width of the door.

摘要： According to one embodiment, a user detection system includes a camera, a boundary detector, a user detector and a controller. The camera is installed in a peripheral region of a door, and captures a running region when opening or closing the door and a region near the door. The boundary detector detects a boundary between a first structure and a second structure in the region near the door based on an image captured by the camera. The user detector detects whether there is a user in the running region based on a result detected by the boundary detector. The controller controls an open/close operation of the door based on a result detected by the user detector.

摘要： According to one embodiment, an image detection system includes an imaging apparatus, an edge extraction unit, a specific-edge extraction unit, a candidate area extraction unit, and a to-be-detected area determination unit. The edge extraction unit extracts edges each representing a boundary line between areas with different features. The specific-edge extraction unit extracts specific edges including at least remaining edges present in background image and input image. The candidate area extraction unit extracts candidate areas for a preset area to be detected. The to-be-detected area determination unit determines the area to be detected from candidate areas extracted.

摘要： In an elevator system according to one embodiment, an imaging unit performs an imaging operation to obtain an image of a hall, the doorway of a car and the vicinity of the doorway, a measuring unit measures an exposure amount of a specified detection area in the image, and a controller adjusts an exposure adjustment parameter of the imaging unit in accordance with the measured exposure amount. While the door is being opened, as the detection area, the controller specifies a detection area in the interior of the car, and notifies the measuring unit of the specified detection area, and while the door is being closed, as the detection area, the controller specifies a detection area in the hall, and notifies the measuring unit as the specified detection area.
