Problems solved by technology

[0007] Through the above analysis, the problems and defects of the existing technology are: the imaging cost of the intelligent detection device is high, and the speed, accuracy and intelligence of the linear structure data fusion and stitching into two-dimensional images have defects

[0008] The difficulty in solving the above problems and defects is as follows: With the continuous improvement of detection accuracy and accuracy, the resolution of the visual acquisition device adopted is continuously improved. For example, the mainstream line scan camera has reached 8K or even higher, and the area array camera has generally reached Tens of millions of pixels, which not only puts forward high requirements on the storage and computing capabilities of the processing device, but also requires higher spatial registration accuracy
