Method for detecting idle objects in elevator car based on image semantic segmentation

Abstract

The invention discloses a method for detecting idle objects in an elevator car based on image semantic segmentation. The method comprises the following steps that when a camera in the elevator car is installed for the first time or the angle of the camera at the later stage is adjusted, the floor area of the elevator car is marked through a tool; when an elevator door is completely closed, a picture is grabbed through the camera at the top of the elevator car so as to obtain the floor area of the elevator car; when the door continues to be kept closed, a time interval is set, one-time picture grabbing and analysis are carried out every other period of time, the area of the floor area of the elevator car is continuously measured, and the result is stored; according to the stored multiple measurement results, the floor area of the elevator car, which is obtained by image semantic segmentation, is compared with the floor area calibrated by a maintenance personnel, if the average value of the floor area of the elevator car is larger than a set threshold value, it is indicated that the idle objects exist in the elevator car, and if the average value of the floor area of the elevator car is smaller than the set threshold value, it is indicated that no object exists; and according to the detection result and the door opening and closing situation, the time length of the existence of the objects during the continuous door closing period is obtained.

Description

technical field [0001] The invention belongs to the technical field of data analysis, and in particular relates to a method for detecting idle items in an elevator car based on image semantic segmentation. Background technique [0002] With the widespread use of elevators, people have higher and higher requirements for the safety and comfort of elevators. Idle items in the elevator car not only reduce the comfort of the elevator, but also bring safety hazards. Contents of the invention [0003] In view of the above technical problems, the present invention provides a method for detecting idle items in an elevator car based on image semantic segmentation. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A method for detecting idle items in an elevator car based on image semantic segmentation, comprising the following steps: [0006] When the camera in the elevator car is ...
