  • Patent number: 11526161
    Abstract: A human flow estimation system comprises: a sensor network comprising a plurality of sensors arranged in a to-be-estimated region for detecting the human flow; a model building module configured to build a human flow state model based on arrangement positions of the sensors, and build a sensor network model based on data of the sensors; and a human flow estimation module configured to estimate the human flow and provide a data weight of the estimated human flow based on the human flow state model and the sensor network model. The human flow estimation system further comprises a failure detection module configured to detect whether each sensor in the sensor network is abnormal, and the model building module is further configured to adjust the human flow state model and the sensor network model when an exception exists on the sensor.

  • Patent number: 11113516
    Abstract: The present invention provides a human flow estimation system and a human flow estimation method. The human flow estimation system comprises: a sensor network comprising a plurality of sensors for collecting data and respectively arranged in each to-be-estimated region and between the to-be-estimated regions; a model building module configured to build a horizontal human flow model and a vertical human flow model based on the plurality of sensors arranged in each to-be-estimated region and/or arranged between the to-be-estimated regions; and a human flow estimation module configured to estimate human flow data based on the horizontal human flow model and the vertical human flow model. The human flow estimation system and the human flow estimation method according to the present invention can realize high-precision estimation of human flow data in a three-dimensional space.
