Escalator monitoring system

Abstract

The present invention provides an escalator monitoring system which is provided with at least two shooting devices (22a, 22b) at a place where the body of the escalator (11) can be monitored. Each image which is shot through the shooting devices (22a, 22b) is transmitted to an image processor (24). In the image processor (24), the three-dimensional information is obtained according to each image.The three-dimensional information is analyzed. The position of a passenger (10) who uses the escalator (11) is detected, wherein the position comprises the depth direction of the shooting range, and simultaneously, the motion of the passenger (10) is detected based on the operation information of escalator (11).

Description

technical field [0001] The invention relates to an escalator monitoring system which uses a camera to monitor passengers using the escalator. Background technique [0002] Escalators (also called people conveyors) installed in buildings and stations usually operate automatically in places where there are no monitoring personnel. Therefore, dangerous states such as those occupants leaning out from the armrest to the outside may be ignored. In addition, even when the passenger falls, it takes time to contact and reach the monitoring personnel, and there is a problem that the response is too late. [0003] In the prior art, in order to solve such problems, for example, in Japanese Unexamined Patent Publication No. 2000-34088 and Japanese Unexamined Publication No. 5-319762, it is proposed to install a photographing device near the escalator, and use the photographing device to photograph An escalator monitoring system that detects the behavior of passengers leaning out or goi...

Problems solved by technology

However, there is still such a problem in the existing escalator monitoring system: as mentioned above, it is very difficult to obtain detailed information related to the depth from the two-dimensional image captured by the shooting device, Therefore, the detection accuracy of passengers is also very low

Therefore, for example, when there are passengers near the handrail of the escalator, due to the shooting angle of the camera device, it is sometimes impossible to correctly determine whether the passenger is leaning out of the handrail or whether he is sitting on the inside of the handrail correctly.

[0008] Also, when a passenger falls down, since the position in the depth direction of the escalator cannot be accurately determined, there is a problem of a response delay.

[0009] Furthermore, if shooting is performed in a crowded state where passengers overlap each other (this is called "occlusion"), it is difficult to correctly detect each passenger from the captured image, so even if there is an accident, there is a possibility of missing
