[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] Such as figure 2 As shown, the test system used to realize the ablation test of the thermal protection structure of the hypersonic aircraft includes two cameras 3, a filter device 4 installed in front of each camera, a synchronization device 5, and an acquisition and processing computer 6; Two cameras 3 with filter device 4 are arranged symmetrically to the object to be measured outside of the arc wind tunnel 2, computer 6 uses synchronization device 5 to drive CCD camera 3 to collect images, and computer 6 collects and processes images . After the test starts, the computer 6 uses the synchronization device 5 to drive the CCD camera 3 to collect the image of the measured object 1. During the collection, the filter device 4 can be adjusted in real time to select the light intensity to obtain the best image quality. Finally, the computer 6 processes the i...
