Abstract

The invention discloses an elevator door state detecting method based on an image column diagram. The method comprises the following steps that 1, video image information in a car platform sill is collected; 2, analysis is carried out according to the collected video image information, whether an elevator door of the elevator car platform sill monitored currently is in an opening state or not is judged, and the result is conveyed to a data analyzing unit; and 3, according to a detecting area transmitted by a video collecting module, a door state detecting unit registers a background template under the door complete closing state in an H channel of an HSV space, constantly calculates the difference between a current frame column diagram and a background column diagram later, and judges theopening and closing state of the door.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and in particular relates to an elevator door state detection method and system based on an image histogram. Background technique [0002] At present, the elevator has become the standard equipment in many buildings in the city, and it is an important means of transportation for people in modern life. Due to its frequent use and its own airtight characteristics, the elevator environment has a strong demand for image monitoring. The traditional elevator monitoring only has the basic video recording function, and cannot intelligently judge the current state of the elevator door. When the elevator fails suddenly, the community management personnel can only query the monitoring images laggingly, and the crisis handling mechanism responds slowly and has certain hysteresis. [0003] Chinese invention patent application CN106204659A discloses an elevator door opening and closing detection meth...
