Embodiment Construction
[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0047] The present invention proposes a measuring device and method based on a sensor capable of measuring multiple surfaces such as a spectral confocal probe to realize the surface shape and thickness distribution of the inner and outer walls of a thin-walled shell. The axis drives the spectral confocal probe to perform profiling scanning motion along the surface of the thin-walled shell, and the single-sided thickness measurement avoids the mechanical interference problem of the through-beam thickness measurement, and simultaneously collects the thin-walled shell during the scanning process. The position and thickness information of the inner and outer walls in the body can ensure the consistency of the coordinates of the detection data in space, so as to realize the high-precision and rapid detection of the shape and thickness distribution of the inner and ...
