Abstract

The invention relates to a method and a device for measuring the three-dimensional attitude of a part in a floating liquid. The device is composed of three parts, namely a mechanical part, an image acquisition part and an image processing part. The mechanical part is composed of a glass oil tank, a supporting frame, an equipment mounting table, a constant-temperature oil tank and a constant-temperature oil tank controller thereof, a pitching deflection table, a two-dimensional sliding table, two one-dimensional sliding tables and a sliding table controller of the two-dimensional sliding tables. The image acquisition part is composed of a measured part, three lenses, three camera sensors, three annular light sources and a light source controller. The image processing part is composed of a computer and an image processing algorithm. The device disclosed by the invention has the advantages of non-contact measurement, high efficiency, high precision, automatic measurement and the like.

Description

technical field

[0001] The invention relates to the field of measuring the three-dimensional attitude of a part in a floating liquid, in particular to a measuring device for detecting the three-dimensional attitude of a part in a normal temperature or high temperature floating liquid. Background technique

[0002] The float assembly is a key component in the inertial instrument, and its shape is similar to a cylinder. The static unbalance of the float (that is, the coincidence degree between the center of mass and the center of buoyancy) will cause the float to tilt axially and radially when it is suspended in the buoyant liquid. direction of rotation. The three-dimensional attitude information of the float in the buoyant liquid directly affects the accuracy level of the inertial instrument, and determines whether the float can be installed in the inertial instrument and put into actual combat use.

[0003] The traditional measurement method of the three-dimensional attitud...
