The invention discloses an abradable seal coating crack detection method based on laser bidirectional scanning thermal imaging, which comprises the following steps: a laser collimator moves along the length direction of a test piece to perform bidirectional scanning on the surface of the test piece, and an infrared camera acquires a thermal image of the surface of the test piece; normalization subtraction processing is carried out on images obtained through bidirectional scanning of the same position of a test piece, temperature gradient values of a normalized image sequence are sorted by taking pixel points as units along a time axis, and a thermal image composed of the pixel points with the maximum gradient value is selected as a final result. According to the invention, a special temperature field which is very sensitive to existence of crack defects can be formed in a laser heating area, and in the temperature field, noise signals generated by optical characteristic difference of the ...

The invention discloses a crack detection method and device based on dislocation subtraction of laser heating areas, a storage medium and an electronic device. The method comprises the following steps: in laser bidirectional scanning thermal imaging, thermal images collected by a thermal imager all display temperature changes in the same area of the surface of a test piece. Therefore, by taking the pixel point as a unit, the temperature gradient value sorting along the time axis can be carried out on the thermal image sequence subjected to the dislocation subtraction processing of the laser heating area. Then, a thermal image composed of the pixel points with the maximum temperature gradient value at each position can be selected as a final detection result. The position relation between the crack and the laser heating area can be ignored, and the maximum value of the temperature gradient is accurately extracted to serve as the characteristic signal of the crack defect, so that a visual ...
