Problems solved by technology

Among them, the contact type is typically a three-coordinate measuring instrument. Although this method has high precision, it is easy to damage the probe and scratch the measured part because the probe needs to be in contact with the measured object during measurement; so there is no need to touch the measured object. The non-contact measurement method has a wider application prospect. This type of method is typified by the projection grating method, which has the advantages of fast speed, simple structure and low cost. However, due to the constraints of CCD camera precision and other factors, its measurement accuracy is low.

Abstract

The invention relates to an instrument for measuring a three-dimensional profile of an object, which is used for measuring the three-dimensional appearance and profile of the object. The instrument comprises a dustproof base (1), a bearing plate (2), lifting rotating components (3), a stepper motor (4), a coupling shaft (5), a measuring cylinder (6), a carrying platform (7) and a protective outer cover (8), wherein the lifting rotating components (3) comprise a transmission nut (31), a bearing (32) and a main support (33). The instrument for measuring the three-dimensional profile of the object has the advantages of high measurement accuracy and convenient operation.

Description

(1) Technical field [0001] The invention relates to a measuring instrument, in particular to a three-dimensional profile measuring instrument for measuring the three-dimensional appearance profile of an object. (2) Background technology [0002] At present, there are mainly two types of measurement methods for the three-dimensional contour of objects: contact and non-contact. Among them, the contact type is typically a three-coordinate measuring instrument. Although this method has high precision, it is easy to damage the probe and scratch the measured part because the probe needs to be in contact with the measured object during measurement; so there is no need to touch the measured object. The non-contact measurement method has a wider application prospect. This type of method is typified by the projection grating method, which has the advantages of fast speed, simple structure and low cost. However, due to the constraints of CCD camera precision and other factors, its meas...
