Abstract
According to an aspect, there is provided a device for determining a fill rate of an elevator car. The device may obtain a first set of sensor data associated with an empty elevator car from at least one time-of-flight sensor arranged in the elevator car, the first set of sensor data comprising first data points; remove data points associated with walls of the elevator car from the first data points to obtain floor data points; determine a bounding volume surrounding the floor data points; obtain a second set of sensor data associated with the elevator car from the least one time-of-flight sensor, the second set of sensor data comprising second data points; and calculate the fill rate of the elevator car at least partly based on the second data points inside the bounding volume.
Claims20
A device for determining a fill rate of an elevator car, comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the device to at least perform:
- obtaining a first set of sensor data associated with an empty elevator car from at least one time-of-flight sensor arranged in the elevator car, the first set of sensor data comprising first data points;
- obtaining floor data points based on the first data points;
- determining a bounding volume surrounding the floor data points;
- obtaining a second set of sensor data associated with the elevator car from the least one time-of-flight sensor, the second set of sensor data comprising second data points;
- and
- calculating the fill rate of the elevator car at least partly based on the second data points inside the bounding volume.
A method for calculating a fill rate of an elevator car, the method comprising:
- obtaining a first set of sensor data associated with an empty elevator car from at least one time-of-flight sensor arranged in the elevator car, the first set of sensor data comprising first data points;
- obtaining floor data points based on the first data points;
- determining a bounding volume surrounding the floor data points;
- obtaining a second set of sensor data associated with the elevator car from the least one time-of-flight sensor, the second set of sensor data comprising second data points;
- and
- calculating the fill rate of the elevator car at least partly based on the second data points inside the bounding volume.
