    Abstract: The present disclosure provides an automatic tracking shopping cart. The automatic tracking shopping cart comprises an automatic tracking device. The automatic tracking device is fixed to a body of the shopping cart, operative to control movement of the shopping cart for tracking a target object. The automatic tracking device comprises: an image collection unit configured to collect a color image and a depth image of a field of image; a processing unit configured to identify the target object based on the collected color image and depth image, and determine a motion parameter of the shopping cart based on a position and/or movement of the target object; and a shopping cart driving unit configured to drive the shopping cart to move based on the determined motion parameter. A method for automatically controlling movement of a shopping cart to track a target object is also provided.

    Abstract: The present application discloses a system for dispatching cleaning robots. The system includes an input subsystem configured to provide an input signal including information about foot traffic in a time period in an area. The system includes a processing subsystem to receive and process the input signal and further to determine a cleaning task under an operation scheme and generate a control signal for the cleaning task. Further the system includes a communication subsystem configured to receive the control signal from the processing subsystem and one or more first signals respectively from the one or more cleaning robots. The communication subsystem sends the control signal based on the one or more first signals to dispatch at least one cleaning robot to the area to perform the cleaning task and receives one second signal from the cleaning robot to update the operation scheme.

    Abstract: The present disclosure provides a pedestrian tracking method including: acquiring at least one piece of first video data and at least one piece of second video data; performing facial recognition on at least some first images of the first image frames to obtain tracking data of a first pedestrian including position information thereof at N moments; performing human body detection on at least some second images of the second image frames to obtain tracking data of a second pedestrian including a movement track thereof; determining tracking data of a target pedestrian when deviation between the position information of the first pedestrian at the N moments and the position information of the movement track of the second pedestrian at the same moments is within a preset range. The present disclosure also relates to a pedestrian tracking apparatus, a computing device, a pedestrian tracking system, and a computer-readable storage medium.

    Abstract: A calibration method and a calibration device of a vehicle-mounted camera, a vehicle and a storage medium are provided. The calibration method includes: obtaining an original image including a plurality of first lane lines and captured by the vehicle-mounted camera; determining a region of interest (ROI) including the plurality of first lane lines in the original image; adjusting a pitch angle of the vehicle-mounted camera by detecting a plurality of second lane lines in a first inverse perspective mapping (IPM) image corresponding to the ROI, the second lane lines corresponding to the first lane lines; and adjusting a yaw angle of the vehicle-mounted camera by detecting an IPM binary image of a second IPM image corresponding to the ROI.
