Patent number: 11940525Abstract: An example method to determine an object spin rate may include receiving a radar signal of a particular object in motion. The method may further include converting the radar signal into an input vector. The method may also include providing the input vector as input to a neural network. The neural network may include access to a set of initial data that has been generated based on multiple initial radar signals of multiple initial objects in motion. The method may further include determining a spin rate of the particular object in motion based on an analysis performed by the neural network of the input vector including time and frequency information of the particular object in motion in view of the set of initial data. The analysis may include comparing one or more elements of the input vector to one or more elements of the set of initial data.Type: GrantFiled: August 31, 2021Date of Patent: March 26, 2024Assignee: RAPSODO PTE. LTD.Inventors: Batuhan Okur, Roshan Gopalakrishnan, Saurabh Garg, Lodiya Radhakrishnan Vijayanand

Publication number: 20230364468Abstract: A launch-monitoring system that models a portion of a golf club, golf swing, and golf ball may include a camera and a radar positioned orthogonally to a swing direction of the golf club. A series of images of the golf ball are collected during and after the golf club contacts the golf ball by the camera. The golf swing is captured by the radar. The images are converted into parameterized motion representations, and the radar signal is converted into time-frequency images, which are sent to a convolutional neural network. The convolutional neural network outputs golf club parameters, golf swing parameters, and golf ball parameters, which generate a visual model of the golf club, golf swing, and golf ball in a virtual space. The parameterized motion representations of the golf ball and the time frequency images of the golf swing are not correlated and operate independently from each other.Type: ApplicationFiled: July 28, 2023Publication date: November 16, 2023Applicant: RAPSODO PTE. LTD.Inventors: Batuhan OKUR, Osman Murat TEKET, Roshan GOPALAKRISHNAN, Lodiya Radhakrishnan VIJAYANAND

Patent number: 11077351Abstract: A golf launching monitoring arrangement allows equipment to be placed at a position behind the player (i.e., behind the golf ball), to measure both club and ball movement. A 3D scan of the club head before the play serves two purposes: 1) 3D registration that enables accurate measurement of the club head position and orientation for the camera system measuring the club movement from the back; 2) for reconstruction of the launching scene. With a 3D model of the club head, a simple 3D model of the golf ball and accurate measurement of their movement during the play, a full 3D golf launching scene can be reconstructed authentically. With this reconstruction, the movement of both the club head and the resulting ball movement can be replayed at any viewing angle, with any frame rate and at whatever resolution for the players or the coaches to view and analyze.Type: GrantFiled: May 28, 2019Date of Patent: August 3, 2021Assignee: RAPSODO PTE.
