Abstract

The invention provides an image processing device which improves the detection precision of the offset of the installation position of a camera. According to one embodiment, an image processing deviceis provided near a door of a car and detects an offset of a mounting position of a camera that captures an image including an inside of the car and an elevator hall. The image processing device includes an acquisition part and a first detection part. The acquisition part acquires, from the camera, an image captured in a state in which a plurality of markers capable of distinguishing from the floor surface of the car and the floor surface of the elevator hall are provided. The first detection part recognizes the plurality of markers from the acquired image, and detects an offset in the mounting position of the camera on the basis of the recognized plurality of markers when the distance between the recognized plurality of markers satisfies a preset condition.

Description

[0001] This application is based on Japanese Patent Application No. 2019-053669 (filing date: 3 / 20 / 2019), and enjoys priority based on this application. This application incorporates this application in its entirety by reference. technical field [0002] Embodiments of the present invention relate to an image processing device. Background technique [0003] In recent years, various techniques have been considered in order to prevent persons and objects from being caught by elevator car doors. For example, a technique of detecting a user moving toward an elevator using a camera and prolonging the door opening time of the elevator door is conceivable. [0004] In such a technique, it is necessary to accurately detect a user moving toward an elevator from an image captured by a camera. However, if the installation position of the camera is shifted, the image captured by the camera will be rotated or shifted to the left and right, which may lower the detection accuracy of the ...
