Abstract

The present disclosure relates to a temperature deformation synchronous measurement system and method based on sub-channel photosensitive, wherein the system includes: a single-point temperature measurement device, used to measure the temperature of a reference point on the surface of the measured object; an image acquisition device, used to obtain the The surface image of the measured object; the optical window integration device, including a plurality of different optical windows; the synchronization control device, used to control the optical window integration device to switch the optical window, and control the image acquisition device to obtain the surface image of the measured object through the switched optical window The processing device is used to extract the gray value of different optical channels in the surface image of the measured object, and obtain the deformation field and temperature field of the measured object surface according to the gray value and the temperature of the reference point. Through the present disclosure, the optical information of the surface of the measured object is subjected to sub-channel photosensitive and imaging in a high-temperature environment, avoiding mutual interference of radiated light imaging and reflected light imaging, and realizing high-precision simultaneous measurement of temperature field and deformation field in a high-temperature environment.

Description

technical field [0001] The present disclosure relates to the technical field of optical measurement, in particular to a temperature deformation synchronous measurement system and method based on sub-channel photosensitive. Background technique [0002] At present, in the non-contact optical measurement of the physical parameters of the object surface in a high temperature environment, the simultaneous measurement of the deformation field and temperature field of the object surface is of great significance. However, in the related art, due to mutual interference between radiated light imaging and reflected light imaging, the accuracy of simultaneous measurement of temperature deformation is affected. Contents of the invention [0003] In view of this, the present disclosure proposes a temperature deformation synchronous measurement system, method, device and storage medium based on sub-channel photosensitive. [0004] According to an aspect of the present disclosure, a tem...
