Trajectory detection and feedback system

摘要

A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and/or one or more observers in the area. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and/or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner.

主权项

1. A system, comprising:
at least one sensor configured to measure a motion of a basketball in free flight toward a basketball hoop during a basketball shot and to provide sensor data indicative of the measured motion; a sound projection device; and an electronic device configured to determine, based on the sensor data, an angle of a trajectory of the basketball when the basketball is proximate to the basketball hoop during the basketball shot, the electronic device further configured to automatically generate, based on the determined angle, feedback information associated with the motion of the basketball during the basketball shot and to automatically output the feedback information in an auditory format via the sound projection device in response to the basketball shot, wherein the feedback information is indicative of the angle.
