Abstract

The invention discloses an elevator safety marker positioning method and system based on a visual word band. The elevator safety marker positioning method comprises the following steps that S1, a marker is arranged on an elevator door; S2, real-time image data in an elevator car are acquired at an image acquisition visual angle that can completely cover the area of the elevator door; S3, data sentfrom sensors are acquired, and the speed value is obtained through calculation; S4, the specific current position of the safety marker is determined when the elevator moves (the elevator door is closed) according to image data transmitted based on video acquisition and a signal which indicates whether the elevator moves or not and is transmitted from an elevator speed acquisition unit; and S5, the corresponding position of the safety marker in a monitoring image is extracted according to specific coordinate information transmitted from a safety marker detection unit so as to be used as inputinformation for subsequent analysis of the door motion state.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and in particular relates to a method and system for locating elevator safety markers based on visual word tapes. Background technique [0002] As an important means of transportation in the current society, the elevator has a strong demand for image monitoring due to its frequent use and the airtightness of its environment, and it is also a hot scene for monitoring equipment installation. In the past, elevator monitoring was just a video recording and display function. With the development of artificial intelligence technology, more and more technicians began to analyze the status of elevator door switches and whether the elevator is running normally based on monitoring images. This analysis method based on image processing technology generally needs to mark the most specific area on the elevator door, that is, the safety marker on the elevator door, as the main target for judging the op...
