Abstract

The invention provides a three dimensional morphology measuring instrument control method and system; the method comprises the following steps: calibrating a translation shaft; calibrating a turning axle axial direction, using an initial attitude matrix to express a target point present position, and using an X turning axle constant matrix to express the target point target position; rotating the turning axle, thus converting the initial attitude matrix into a quasi X turning axle constant matrix, wherein the reference axis directions of the quasi X turning axle constant matrix and the X turning axle constant matrix are same; translating the translation shaft, thus allowing the quasi X turning axle constant matrix origin to overlap with the X turning axle constant matrix.

Description

technical field [0001] The invention relates to the technical field of measuring instrument control, in particular to a control method and system for a three-dimensional shape measuring instrument. Background technique [0002] At present, the comparison and detection of forensic evidence, such as bullet bullets, shell casings, and traces of tool lines, is still in the state of storing and analyzing physical samples, and the detection of trace information still stays in the direct observation of two-dimensional with a single instrument. At the technical level of image comparison, it is impossible to solve the problem of precise positioning and measurement in three-dimensional space object shape technology and trace comparison technology. [0003] In recent years, with the maturity and development of the non-contact detection technology that was originally mainly used for the reconstruction of the three-dimensional shape of the object surface in engineering, there has been ...
