  • Patent number: 11687086
    Abstract: A robot includes an image sensor that captures the environment of a storage site. The robot visually recognizes regularly shaped structures to navigate through the storage site using various object detection and image segmentation techniques. In response to receiving a target location in the storage site, the robot moves to the target location along a path. The robot receives the images as the robot moves along the path. The robot analyzes the images captured by the image sensor to determine the current location of the robot in the path by tracking a number of regularly shaped structures in the storage site passed by the robot. The regularly shaped structures may be racks, horizontal bars of the racks, and vertical bars of the racks. The robot can identify the target location by counting the number of rows and columns that the robot has passed.

  • Patent number: 11657537
    Abstract: A method of calibrating a vehicular vision system includes mounting a camera at a vehicle moving along a vehicle assembly line. Responsive to processing of image data captured by the camera, ground features adjacent to the vehicle are determined and the determined ground features are tracked over two or more frames of captured image data using optical flow. A misalignment of the camera is determined via tracking the determined ground features as the vehicle moves along the straight path portion of the end of line test portion of the vehicle assembly line. Responsive to determination of misalignment of the camera at the vehicle, the vehicular vision system is calibrated using an assumption that the determined ground features lie in a plane parallel to a planar portion of a ground surface adjacent the straight path portion of the end of line test portion of the vehicle assembly line.

  • Patent number: 11592796
    Abstract: The present invention is a water fountain control system that utilizes cameras to analyze movements of a human subject, and actuates one or more water fountain controllers in response to the movements to create a display incorporating spray patterns of the flowing water. The camera system records video in real time and generates optical signals that are sent to a processor running software that assesses the dimension, position, stance, and/or motion of the human subject and converts the data into recognized classes of movements and/or poses. Once the processor identifies the type of movements and/or poses, it sends signals to the actuators of the water fountains to control the fountains in a manner that implements stored predetermined visual effects generated by the fountain to create a visual presentation to an audience.
