Abstract
Systems and methods for monitoring an operation of a door of a public transportation vehicle are disclosed. In an embodiment, the system includes an optical sensor unit and a control unit. The optical sensor is arranged at a distance from the door and configured to record a movement of the door during an opening and/or a closing. The control unit is configured to (1) determine a position of a reference point of the door based on the recorded movement of the door, (2) determine a parameter of the movement of the door during the movement based on the determined position of the reference point, (3) determine a deviation of the parameter of the movement from a predetermined/allowed range of values of the parameter, and (4) determine an error in the operation of the door based on the determined deviation.
Claims15
A system for monitoring an operation of a door of a public transportation vehicle, comprising:
- a video camera arranged at a distance from the door, the video camera being configured to record a movement of the door during at least one variation selected from the group consisting of opening and closing;
- and
- a controller arranged to receive video data from the video camera, the controller being configured to:
- determine a position of a reference point of the door in the video data;
- determine a parameter of the movement of the door as a function over time from the video data based on the position of the reference point;
- and
- determine whether the movement of the door is normal or anomalous by determining whether the parameter as a function over time deviates from normal operations of similar doors based on an artificial intelligence algorithm with access to a database of recordings of the parameter as a function over time for a plurality of previously recorded doors, wherein the recordings include door movements from doors working normally and door movements from doors working with an anomaly.
A method for monitoring an operation of a door of a public transportation vehicle, comprising the steps of:
- using a video camera to record video data of a movement of the door during at least one variation selected from the group consisting of opening and closing;
- determining a position of a reference point of the door in the video data;
- determining a parameter of the movement of the door as a function over time during the movement from the video data based on the position of the reference point;
- and
- determining whether the movement of the door is normal or anomalous by determining whether the parameter as a function over time deviates from normal operations of similar doors based on an artificial intelligence algorithm with access to a database of recordings of the same parameter as a function over time for a plurality of previously recorded doors, wherein the recordings include door movements from doors working normally and door movements from doors working with an anomaly.
