[0027] The description will be further described below in conjunction with the embodiments and the drawings of the description.
[0028] Set up a binocular stereo vision system, fix two industrial cameras on the optical anti-vibration platform, determine the field of view and spacing of the cameras according to the distance between the optical marking points to be measured, and make the angle between the two cameras around 30°, Quartz glass with circular coding dots is placed on the surface of the specimen sprayed with speckles. After the heater temperature reaches a stable level, the test measurement is performed.
[0029] The method of the present invention for correcting the influence of hot air flow on the accuracy of digital image correlation measurement includes the following steps:
[0030] 1) Arrange the test equipment required by the 3D-DIC method: After spraying a uniform matte white primer on the surface of the test piece and drying it, spray evenly matte black speckles on...
