Omni-directional target ball

Abstract

The invention discloses an omni-directional target ball which comprises a round target ball plate. A plurality of partition plates are vertically arranged at two sides of the target ball plate and areused for dividing the target ball plate into a plurality of target ball spaces, wherein the intersection point of the target ball spaces is the circle center of the target ball plate; and the partition plates and the target ball plate form a ball shape and are integrated into one. Four partition plates are vertically and uniformly arranged at each of two sides of the target ball plate respectively; the adjacent partition plates are perpendicular to the corresponding target ball plate; and the partition plates at the two sides are symmetric to the target ball plate. In addition, the omni-directional target ball includes a support rod that is connected with a collection part of all partition plates at one side far away from the target ball plate. According to the invention, the omni-directional target ball has a simple and reasonable structure. The partition plate and the target ball plate are integrally formed to ensure the high stability of the target ball; a measurement cooperative target with a horizontal 360-degree angle and a pitching angle of -85 to + 90 degrees can be provided; manual or mechanical target ball rotation is not required; a high-precision target tracking measurement task can be realized; and the omni-directional target ball is suitable for tracking measurement of form and position errors of complex moving objects such as robot calibration and the like.

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing spherical target ball often has a groove on one side and is composed of three mutually perpendicular reflectors inside. The working area is very small, and it is often necessary to manually or mechanically rotate the target ball to adapt to the adaptation and adjustment of the horizontal 360-degree working area; it is especially difficult to track and measure the shape and position errors of complex moving objects such as robot calibration and multi-axis mechanical calibration. The effective working area cannot be effectively expanded, and the operation and use effect is poor; the present invention provides an all-round target ball that solves the above problems
