Abstract

The invention relates to a non-contact dynamic profile measuring method and a measuring device. A monochromatic laser with a sheet laser is arranged in front of a measured object, and the plane of the sheet laser is vertical to the plane of the measured object. A digital camera with a narrow bandpass filter is arranged in side front of the measured object, and strongest laser energy is irradiated to a measuring area of the measured object. The camera shoots concave and convex changed images of the measured object, and the shot images are input into a computer through an image acquisition card and are compared with a target image with a known depth gradient so as to calculate the dynamic data of appearance profile changes of the measured object. Only a low-price semiconductor laser can filter intense light background noise without an expensive high-energy pulse laser, and the semiconductor laser has strong capacity of resisting disturbance, can measure dynamic profile change data of an object under high-temperature flame environment in a non-contact mode and has accurate measurement and calculation result. Required equipment is simple and easy to use, operate and maintain.

Description

technical field [0001] The invention relates to the technical field of laser applications, in particular to a non-contact dynamic profile measurement method and a measurement device. Background technique [0002] Topography measurement problems are often encountered in real work. For example, when performing ablation tests on some high-temperature-resistant materials, it is necessary to dynamically measure the ablation situation; Measurements are required to ensure proper use. However, there is a lack of suitable measuring methods and measuring devices in the prior art. Contents of the invention [0003] The object of the present invention is to provide a convenient and accurate non-contact dynamic profile measurement method and a simple-structured and easy-to-use measuring device to make up for the deficiencies in the prior art. [0004] The object of the present invention is achieved through the following technical solutions, a non-contact dynamic profile measurement m...
