Abstract

The invention provides a detection system for elevator door blocking behavior based on video analysis, which includes a video acquisition unit, a door state analysis unit, an alarm logic unit and a multimedia prompt unit. The present invention also provides a method for detecting elevator door blocking behavior based on video analysis using the above-mentioned system, including the steps of: pasting markers; collecting information on the location of the elevator door markers; analyzing and judging the state of the elevator door; judging whether there is a blocking door Behavior; play a reminder broadcast. The present invention adopts the method of area acquisition, and calibrates the set acquisition area in the form of a label, so that the boundary of acquisition is more obvious, and the comparison with the background is more accurate, thereby overcoming the interference of the edge of the elevator door and the background occluder, and improving detection accuracy.

Description

technical field

[0001] The invention relates to the technical field of video detection and the technical field of elevator safety. Background technique

[0002] The behavior of the elevator blocking the door occurs from time to time, which seriously endangers the safe operation of the elevator. In the current elevator accidents, a large part is caused by the blocking door. In addition, some residents lack the common sense of elevator safety and use various objects to block the doors, even including baby carriages (with sleeping children in them). Little do they know that this poses a huge safety hazard. Once the elevator doors are forcibly closed, the consequences will be disastrous.

[0003] At present, there have been researches on the behavior of elevator blocking doors. For example, Chinese patent application CN201710369596.6 discloses a method for detecting elevator door opening and closing based on camera images. The detection method uses elevator door boundary informa...
