Abstract

The invention discloses a method for detecting idle items in an elevator car based on image semantic segmentation, which comprises the following steps: when the camera in the elevator car is installed for the first time or when the angle of the camera is adjusted later, the ground area of ​​the elevator car is marked by a tool ; When the elevator door is completely closed, capture a picture through the camera on the top of the car to obtain the floor area of ​​the elevator car; when the door continues to be closed, set the time interval, and take a picture and analyze it every once in a while. The area of ​​the car floor area is continuously measured and the results are saved; using the saved multiple measurement results, compare the car floor area obtained by image semantic segmentation with the floor area calibrated by the maintenance personnel. If the average value is greater than the set threshold, It means that there are idle items in the elevator car, and if it is less than the set threshold, it means that there is no item; according to the detection result and the opening and closing of the door, the duration of the item's appearance during the continuous 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 large-scale use of elevators, people have higher and higher requirements for the safety and comfort of elevator rides. Idle items in the elevator car not only reduce the comfort of the elevator, but also bring security risks. SUMMARY OF THE INVENTION [0003] In view of the above existing 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 above-mentioned technical problems, the present invention adopts the following technical scheme: [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...
