Elevator car passenger number detection method and system based on double-path monitoring video analysis

Abstract

The invention relates to an elevator car passenger number detection method and system based on double-path monitoring video analysis. The method comprises the following steps that firstly, the video data of outer and inner paths (I and II) obtained through monitoring an elevator are transmitted to a hard disk video recorder; secondly, the hard disk video recorder sends the two paths of videos toan algorithm module 1 and an algorithm module 2 for analysis correspondingly; the algorithm module 1 analyzes the I-path video and calculates the total number of people going in and out of the car according to the duration time of the opening and closing processes of the elevator door; the algorithm module 2 analyzes the II-path video, and calculates the direction function of going in and out ofpeople according to the change of the foreground area before and after the opening and closing of the elevator door; and finally, the calculation result of the algorithm module 1 and the calculation result of the algorithm module 2 are sent to an algorithm module 3, the algorithm module 3 is used for taking the product of the total number of people going in and out of the car and the direction function as the net number of people entering the car, and the calculation result of the algorithm module 3 is stored in a database for analysis or giving an alarm when the number of people is found to be overloaded.

Description

technical field [0001] The invention relates to the application of intelligent video image analysis in artificial intelligence technology, in particular to a method and system for detecting the number of passengers in an elevator car based on dual-channel monitoring video analysis. Background technique [0002] Elevators have gained popularity in modern high-rise buildings. The elevator group control system must be able to obtain information about the number of people in the elevator car. This is because: first, the most basic and important performance requirement of an elevator is safety, and measuring the number of people in the car can prevent overloading and stampede accidents; second, the elevator group control system needs to obtain information on the number of people in the car, through intelligent Scheduling algorithms manage multiple elevators in order to improve user comfort and reduce elevator energy consumption. [0003] The traditional technologies for detecti...
