Description

Technical Field

[0001] The utility model relates to the technical field of industrial measurement, in particular to a waterproof reference point used in conjunction with a laser tracker on large equipment. Background Art

[0002] At present, the deformation of large equipment is mainly measured by setting external reference points. However, these reference points are usually exposed to the air. After long-term corrosion, the references will become inaccurate and will be affected by foundation settlement. For example, "A method for analyzing the overall deformation of structures based on three-dimensional laser scanning technology", "A device for arranging wall control points for laser trackers" and "A target ball base for detecting reference points of laser trackers" all use external reference points to measure the deformation of equipment. Their disadvantages are: in the process of measuring equipment deformation, the deviation during equipment processing cannot be eliminated; the reference points and equipment are independent of each other. Since the equipment or the reference points will have a certain settlement or deformation, the error will become larger as the equipment is used for a longer period of time. Utility Model Content
