Abstract

The invention discloses a flatness detecting device based on an information fusion technology, belonging to the technical field of measurement. According to the flatness detecting device disclosed by the invention, mercury is injected in a hollow glass ball; a mercury level is used as a reference face in the measurement; and the glass ball and a plane to be detected are in point contact. No matter how the hollow glass ball is placed, the internal mercury level keeps unchanged relatively to the height of a lowest point of the glass ball, so that the mercury level accurately represents the height change on the point on a plane of a working platform. A measuring method disclosed by the invention has less needed hardware; the calculation amount is small; and the precision and the detection efficiency in flatness detection can be improved.

Description

technical field [0001] The invention belongs to the technical field of multi-information fusion detection, and in particular relates to a flatness detection device based on information fusion technology. Background technique [0002] The existing large-plane flatness detection mainly uses manual measurement, which has low efficiency and poor precision, and cannot meet the requirements of rapid detection in industrial production. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a flatness detection device based on information fusion technology, the purpose of which is to automatically and efficiently measure flatness, and to automatically record the data into a computer. [0004] The flatness detection device based on information fusion technology provided by the present invention is characterized in that: the laser emitter (6) is an inline laser emitter, and is fixed wit...
