Methods, systems, and apparatus, including medium-encoded computer program products, for 3D flight tracking of objects include a method including determining a golf ball trajectory based on observations by sensor(s), extrapolating the trajectory backward in time, calculating distance measure(s) between the extrapolated trajectory and physical locations, determining one of the physical locations to be an origin of the golf ball based on the distance measure(s) and two types of separately estimated errors, wherein a first of the two types of separately estimated errors affects ball positional error for the initial observations, and a second of the two types of separately estimated errors affects an angle of the extrapolated trajectory; and presenting golf ball data on a display device associated with the origin of the golf ball.

A shot identifying module 220 identifies a flight distance of the golf ball and an angle of a direction from the measurement terminal 10 toward the golf ball with respect to a direction toward which the user terminal 10 is directed at a time of the measurement. A terminal position and orientation identifying module 222 identifies a terminal position and a terminal orientation. A ball position identifying module 224 identifies a ball position based on the terminal position, the terminal orientation, the flight distance of the golf ball, and the angle.

Systems and methods are described for generating a three-dimensional track a ball in a gaming environment from a single camera. In some examples, an input video including frames of a ball moving in a gaming environment recorded by a camera may be obtained, along with a camera projection matrix associated with at least one frame that maps a two-dimensional pixel space representation to a three-dimensional representation of the gaming environment. Candidate two-dimensional image locations of the ball across the plurality of frames may be identified using a neural network or a computer vision algorithm. An optimization algorithm may be performed that uses a 3D ball physics model, the camera projection matrix and a subset of the candidate two-dimensional image locations of the ball to generate a three-dimensional track of the ball in the gaming environment. The three-dimensional track of the ball may then be provided to a user device.

Golf entertainment venues with a computing system configured to optically identify and track graphical images located on golf balls hit by players. The graphical image located on a golf ball can be associated with a player and the computing system can assign the player a score when that player's golf ball successfully arrives at a target area. In some embodiments, the graphical images can be printed on the golf balls using, for example, a single pass inkjet printing technique. In some embodiments, the computing system can be configured to sort golf balls based on optically identified graphical images.
