Measuring launch and motion parameters

摘要

The technologies described herein relate to measuring launch parameters of a flying object, such as a golf ball or a baseball. The laser based technology enables a system that is low cost which can measure launch parameters of a ball. The launch parameters are measured and rapid feedback is provided on each ball motion event and the data of every single ball launch data is stored in the backend server. The system may include a transmitter optical subassembly (TOSA), a receiver optical subassembly (ROSA), a primary processing unit, a camera subsystem, a data processing, a feedback display unit, and a backend server.

主权项

1. An apparatus for monitoring launch parameters, comprising:
a transmitter optical subassembly including at least one laser source configured to transmit a sheet of light such that a flying object passes through the sheet of light along an expected flight path of the flying object; a receiver optical subassembly including a photodetector configured to receive light transmitted by the transmitter and reflected back from the flying object as the flying object passes through the sheet of light, wherein at least one preliminary launch parameter of the flying object is determined based on the light reflected back from the flying object; and a camera subsystem comprising a camera having a field of view, the camera subsystem configured to take a plurality of pictures of the flying object in response to a triggering event that is based on the at least one preliminary launch parameter, and the plurality of pictures of the flying object are taken in a relevant area within the field of view that is determined based on the at least one preliminary launch parameter.
