Abstract: Disclosed are techniques for elevator control. In one aspect, a sensor senses time series data. A system module identifies a feature point of a target object in the time series data, determines whether feature point coordinates of the feature point are located in an offset space, wherein the offset space has a spatial offset to a button, and sends a control signal if the offset space does not overlap with a first sensing range and the system module determines that the feature point coordinates are located in the offset space for a duration exceeding a first threshold time, or if the offset space overlaps with the first sensing range and the system module determines that the feature point coordinates are located in the offset space for a duration exceeding a second threshold time. An elevator floor controller receives the control signal and cancels the triggering of the button.
