no. 1 Embodiment approach

[0022] figure 1 It is a block diagram showing the structure of the elevator system of 1st Embodiment. Here, one passenger car is used as an example to describe, but a plurality of passenger cars is also configured in the same way.

[0023] A camera 12 is installed above the entrance and exit of the passenger car 11 . Specifically, in the curtain panel (curtain panel) 11a covering the upper part of the entrance and exit of the passenger car 11, the lens portion of the camera 12 is provided facing the landing 15 side. The camera 12 is, for example, a small surveillance camera such as a vehicle-mounted camera, has a wide-angle lens, and can continuously capture images of several frames per second (for example, 30 frames / second). When the passenger car 11 arrives at each floor and opens the door, the state of the boarding place 15 including the state near the car door 13 in the passenger car 11 is photographed.

[0024] The shooting range at this time is adjusted to L1+L2 (L1>>...

no. 2 Embodiment approach

[0068] Next, a second embodiment will be described.

[0069] In the above-mentioned first embodiment, when the car door 13 is fully opened, the luminance value of the first measurement area 32, which is a portion greatly affected by the car lighting when the car door 13 is fully opened, is the second measurement area, which is a portion where the influence of the car lighting is small. The luminance values ​​of 33a and 33b were compared. On the other hand, in the second embodiment, only the second measurement areas 33a, 33b, which are the portions where the influence of the car lighting is small, are focused on, and the second measurement areas 33a, 33b obtained when the landing 15 is in a bright state The average luminance value is compared with the average luminance value of the second measurement areas 33a, 33b obtained when the car door 13 is fully open.

[0070] In the second embodiment, the storage unit 21 of the image processing device 20 stores in advance the second m...

Abstract

The invention provides an elevator system to prevent a door from being reopened by a shadow of the door at a landing when the landing is in a dark state. An elevator system according to an embodimentincludes an illuminance determination unit (22a) and an analysis control unit (22b). When a car door (13) is fully opened, the illuminance determination unit (22) determines whether the illuminance ofthe landing (15) is lower than the illuminance of a car (11) based on the brightness value of a predetermined measurement area on an image captured by a camera (12). When it is determined that the illuminance of the landing (15) is lower than the illuminance of the car (11), the analysis control unit (22b) restricts the analysis process of the image in consideration that the landing (15) is in adark state.

Description

[0001] This application is based on Japanese Patent Application No. 2019-006818 (filing date: 2019.1.18), and enjoys priority based on this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiment of this invention relates to the elevator system which detects a user using a camera. Background technique [0003] Usually, when the passenger car of the elevator arrives at the boarding place and opens the door, it closes the door after a predetermined time elapses and departs. At this time, the user of the elevator does not know when the door of the passenger car is closed, and therefore, when getting on the elevator from the boarding place to the passenger car, the user may bump into the door in the middle of closing the door. [0004] In order to avoid such door collisions when riding, there is an elevator system in which a camera is installed in a passenger car, and a user who boards the passenger car...
