Description

Technical Field

[0001] The utility model relates to the technical field of calibration rods, in particular to a luminous calibration rod. Background Art

[0003] According to Chinese patent number CN113492398B, a calibration rod, a gravity acceleration direction calibration system and a calibration method thereof are provided. The calibration rod comprises: a mounting portion, comprising at least one mounting surface; a connecting rod, a first end of the connecting rod is connected to the mounting portion, and the connecting rod is perpendicular to the mounting surface; a level, a second end of the connecting rod is connected to the level, and the level is used to determine whether the connecting rod is perpendicular to the horizontal plane.
