Document Type and Number:
WIPO Patent Application WO/2023/238217
Kind Code:
A1
Abstract:
Provided is a long-object inspection device capable of more accurately detecting an abnormality in a long object of an elevator. In an elevator (1), a camera (14) captures an image of an upper part or a lower part of a car (6) so that a long object and a sheave are included in the range of the captured image. A long-object inspection device (13) includes a sheave detection unit (18), a long-object detection unit (19), and a determination unit (17). The sheave detection unit (18) performs image processing for detecting a sheave part in the image captured by the camera (14). The long-object detection unit (19) refers to the position of the sheave part detected by the sheave detection unit (18) and performs image processing for detecting a long-object part in the image captured by the camera (14). The determination unit (17) determines if there is any abnormality in the long object on the basis of the detected state of the long object.
