Abstract: An object tracking system is provided and includes a depth sensor deployed to have at least a nearly continuous field of view (FOV) and a controller coupled to the depth sensor. The controller is configured to spatially and temporally synchronize output from the depth sensor and to track respective movements of each individual object within the nearly continuous FOV as each individual object moves through the nearly continuous FOV.

Abstract: The present invention relates to the field of passenger conveyor technologies, and provides a monitoring system of a passenger conveyor and a monitoring method thereof. In the monitoring system and detection method of the present invention, a monitored object of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor to acquire a data frame, and the data frame is analyzed by a processing apparatus to monitor whether the monitored object is in a normal state. The monitored object may include a landing plate, a step, a barrier used in a maintenance and repair working condition and/or a step speed, and the like.

Abstract: A monitoring system and a monitoring method for a passenger conveying device, and the passenger conveying device. The monitoring system comprises an imaging sensor and/or a depth sensing sensor for sensing a monitoring area of the passenger conveying device to acquire data frames; and a processing device for performing data processing on the data frames to monitor whether the monitoring area is abnormal, and configured to comprise: a background acquisition module for acquiring a background model based on data frames sensed when the monitoring area is in a normal state; a foreground detection module for comparing data frames sensed in real time with the background model to obtain a foreground object; a foreground feature extraction module for extracting a corresponding foreground object markup feature from the foreground object; and a state judgment module for judging whether the foreground object belongs to an abnormal population.

Abstract: A method for multiple 3D sensor calibration for a passenger conveyance system, the process including a computing a centroid location from spatial measurements for each of a pair of 3D sensors that form a common field of view via a moving object mathematical model; computing translation parameters from the locations of each centroid location; and correcting one of the pair of 3D sensors to a common world coordinate system from the translation parameters.
