Abstract

The invention provides an adjustable leveling target for mechanical arm calibration. The adjustable leveling target comprises a prism, an outer frame, a rotating shaft, supporting legs and a horizontal base. The prism is arranged in the outer frame, and the prism is connected with the outer frame through the transversely arranged rotating shaft. The supporting legs are arranged at the bottom of the outer frame and perpendicularly arranged on the horizontal base. Horizontal bubbles are arranged on the horizontal base, and a vertical plate perpendicular to the horizontal base is arranged on the horizontal base. The invention further discloses a method for mechanical arm calibration. According to the adjustable leveling target and method for mechanical arm calibration, accurate calibration of a mechanical arm can be ensured, the measurement process is simple and rapid, so that the calibration efficiency is improved.

Description
