Description
technical field [0001] The invention relates to the technical field of measurement, in particular to a geometric tolerance measuring device and a measuring method thereof. Background technique [0002] In order to meet the demand for precise measurement of high-precision large-scale geometric quantities in the fields of modern industry and aerospace, and to meet the requirements of large-scale equipment such as industrial manufacturing, energy equipment, and aerospace, the measurement of large-space coordinates has been extended to 6-dimensional parameters of large-space poses. Measurement, the coordinate measurement system has developed from the traditional orthogonal system to the non-orthogonal coordinate measurement system. Especially with the rapid development of laser measurement and sensor technology, there have been laser measuring instruments that can measure geometric tolerance parameters such as straightness, flatness, perpendicularity, parallelism, and coaxiality...
