The second mounting plate 203 is equipped with a third fine adjustment mechanism 204 and a fourth fine adjustment mechanism 205, which are respectively used to adjust the vertical positions of the image measuring instrument 201 and the spectral confocal microscope 202.

[0034] The linear motor module 3 is provided with a home sensor, a left limit sensor, and a right limit sensor (not shown in the figure). The electric fine-tuning mechanism 205 is provided with a home sensor, an upper limit sensor, and a lower limit sensor (not shown in the figure).

[0035] Referring to Figures 1 to 8 , the working principle of the present utility model is as follows:

[0036] The fuel rod is placed on the support frame 402 of the base 401 as required, and the first mover 301 and the second mover 302 respectively move to the left and right extreme positions of the linear motor 3: the line array camera 101 and the laser profiler 102 are assembled on the first mover 301, and the first mover 301 drives the line array camera 101 and the laser profiler 102 to take the first image. After completion, the rotating mechanism 403 clamps the fuel rod and rotates it by 60°. When the first mover 301 returns, it takes the second image. The image taking is carried out 6 times in sequence. The taken photos and point clouds are stitched together to draw a complete image of the fuel rod; the image measuring instrument 201 and the spectral confocal instrument 202 are assembled on the second mover 302. The second mover 302 drives the image measuring instrument 201 to take images of the head position, several intermediate positions, and the tail position of the fuel rod, and then the obtained images are also stitched together to draw a complete image; the point cloud obtained by the laser profiler 102 is used to measure the length, outer diameter, and straightness of the fuel rod, and the image measuring instrument 201 also measures the length, outer diameter, and straightness of the fuel rod. Then, by using the data fusion method, the weighted fusion method is adopted for the final dimension measurement calculation; after the image obtained by the line array camera 101 is calculated by the deep learning algorithm, the position of the defect in the image is obtained, and then it is mapped to the physical space mainly based on the linear motor module 3 through the transformation matrix. Furthermore, the spectral confocal instrument 202 moves to the corresponding position according to the mapped and transformed coordinates for depth measurement.

[0037] The calculation methods such as image stitching, data fusion, deep learning algorithm, transformation matrix, and mapping adopted in the present utility model all adopt the prior art and will not be elaborated herein.
