Embodiment 1

[0028] A method for automatically identifying passenger information in a passenger cableway car, comprising the following steps:

[0029] (1) Obtain the logo and image of the passenger cableway car, each car has a unique logo, and the car image includes a complete car interior area and car edges;

[0030] (2) Carry out edge detection to the car image, obtain the edge information of the car image, and identify whether there is a passenger in the passenger ropeway car with different signs according to the different edge information of the passenger and the car.

[0031] In the present invention, each car is provided with a unique two-dimensional code or a one-dimensional barcode, and the serial number information of the car is obtained by performing image recognition on it.

[0032] In step (1), when identifying people in the car, since only the information in the car is of interest, a method of establishing a region of interest (region of interests, ROI) is adopted for this pur...

Embodiment 2

[0041] An automatic identification device for passenger cableway car information, each passenger cableway car identified by it has a unique identification, including a photoelectric sensing module, an image acquisition module and an edge detection module; the photoelectric sensing module consists of a photoelectric switch transmitter, Composed of photoelectric switch receivers, the photoelectric switch transmitter and photoelectric switch receiver are fixedly arranged on both sides of the passenger cableway on the car departure platform in an opposing manner, and are used to detect whether the passenger cableway car reaches the designated position; the present invention adopts Infrared photoelectric switch, the infrared photoelectric switch uses the detected cable car to shield or reflect the modulated infrared beam, and is strobed by the synchronous loop to detect the presence or absence of the cable car and generate the switch function. Photoelectric switches can be mainly di...

Abstract

The invention discloses a method and device for automatic identification of passenger information in a passenger cableway car. The method includes the following steps: (1) Obtain the logo and image of the passenger cableway car, each car has a unique logo, and the car image Contains the complete interior area of ​​the car and the edge of the car; (2) Carry out edge detection on the car image, obtain the edge information of the car image, and identify passengers with different signs according to the different edge information of the passenger and the car Whether there are passengers in the cableway car; the present invention can carry out the rescue work of the passenger cableway more correctly and in time to ensure the personal safety of passengers.

Description

technical field [0001] The invention belongs to the field of machine vision, and relates to a method and a device for automatically identifying passenger information in a passenger cableway car based on machine vision technology. Background technique [0002] Passenger ropeway is a kind of public transportation equipment that operates in the air. Because of the special operating environment of passenger ropeway, its safety is very important. According to statistics, there have been many fatal accidents in the cableways built and used in China. In order to ensure the safe operation of the cableway and avoid the occurrence of unfortunate accidents, it has always been the unremitting efforts of governments at all levels and cableway operators to establish an effective safety monitoring system. responsibilities and goals. However, it can be found that many of the existing safety monitoring systems are aimed at the detection of the core components of the cableway, but cannot pro...
