Launch monitor system with a calibration fixture and a method for use thereof
First Claim
1. A launch monitor system for measuring flight characteristics of an object moving in a predetermined field-of-view, the system comprising:
- a support structure;
a lighting unit disposed on the support structure and directing light into the predetermined field-of-view;
a first camera unit disposed on the support structure and pointed toward the predetermined field-of-view; and
a calibration assembly including a calibration fixture; and
at least one telescoping member having a first end coupled to the support structure and a second end contactable with the calibration fixture, wherein the telescoping member has an extended position placing the calibration fixture in the field-of-view of the first camera unit;
wherein the calibration fixture is coupled to the second end of the telescoping member, and the telescoping member has a retracted position where the calibration fixture is out of the field-of-view of the first camera unit; and
wherein the calibration fixture further includes a back wall and first, second and third walls spaced from one another and extending outwardly from the back wall, and two legs, each leg being pivotally connected to the first and second walls.

Abstract
The present invention is directed to a launch monitor system that measures flight characteristics of an object moving in a predetermined field-of-view. The system includes a support structure, a lighting unit, a camera unit disposed on the support structure, and a calibration assembly. The calibration assembly includes a calibration fixture and at least one telescoping member. A first end of the telescoping member is coupled to the support structure and a second end is contactable with or coupled to the fixture. In an extended position of the telescoping member, the calibration fixture is in the field-of-view of the camera unit. In a retracted position, the calibration fixture out of the field-of-view. The calibration fixture further includes contrasting markings. In another embodiment, the system includes a frame and the launch monitor is pivotally suspended from the frame so that it self-levels. The present invention further includes a method of calibrating a launch monitor having a calibration fixture.
