  • Publication number: 20250135316
    Abstract: A system includes a camera capturing images in a first field of view of a sports ball bouncing and rolling, a storage arrangement, and a processing arrangement. The storage arrangement includes a three-dimensional 3D model of a part of a sports play area and the processing arrangement is configured to: detect a pixel location of a ball in an image; determine, based on intrinsic and extrinsic calibration parameters, a camera-ball line comprising a straight line passing through the camera in the direction of the sports ball and to determine, based on the 3D model, an intersection point of the camera-ball line with the 3D model. The processor outputs the intersection point as a 3D position of the ball in the image.

  • Publication number: 20240316402
    Abstract: A system determining a spin axis of a ball includes a radar transmitting a signal into a target area. The radar includes a minimum of three receivers arranged so that two pairs of receivers are not co-linear. The system also includes a Processing Unit (“PU”) receiving data from the radar and determining a radar range of frequencies received at a point in time corresponding to differing velocities relative to the radar of different portions of the ball as the ball is spinning. PU divides the radar frequency range into a plurality of frequency components and calculating, for each of the frequency components, an angular position associated therewith. PU identifies as a projection of the spin axis in a plane perpendicular to a line of sight from the radar to the ball, a line perpendicular to a line represented by the determined angular positions.

  • Publication number: 20220284628
    Abstract: A processor and camera capture data corresponding to a position of a ball and automatically adjust orientation and zoom level of the camera. The processor pre-calibrates the camera so an initial orientation is known in a world coordinate system (WCS) and so different zoom levels are associated with respective parameter values. A first position of the ball in a first image is detected and a first zoom level of the first image and intrinsic parameter values for the first zoom level are read. Based on pan and tilt relative to the initial orientation, the first orientation of the camera is determined. A 3D line through the camera and the ball in WCS is determined based on the first position, the first orientation and parameter values for the first zoom level and a 3D position is determined in WCS along the line based on information extrinsic to the camera.

  • Patent number: 11330379
    Abstract: A hearing system includes a hearing aid (10) and personal communication device (20) connected via a short range data communication link. The hearing aid has a signal processor (13) processing an audio signal according to audio processing parameters, a sub-system applying respective sets of processing parameters for at least two modes, a classifier component (51) statistically analyzing the environment by comparing specific characteristics of an electrical input signal to one or more thresholds. A program selector component (16) selects automatically an appropriate mode for the signal processing sub-system according to the classifier output. The personal communication device offers the user an interface for controlling and interacting with the program selector component of the hearing aid, and for generating and transmitting a notification to the hearing aid. Upon reception of the notification, the processor adjusts at least one of the one or more thresholds used by the classifier component.
