Image calibration system based on dynamic train synchronous sampling

The invention relates to the field of train image recognition, in particular to an image calibration system based on dynamic train synchronous sampling, which is characterized in that an image to be detected is acquired through an image acquisition module, and is detected and compared through a first-stage comparison module, a second-stage comparison module and a third-stage comparison module; and the calibration analysis module is used for carrying out image processing and calibration on the compared image, so that the problems that deviation exists in image synchronous sampling, the image splicing and three-dimensional modeling precision is low in the subsequent train detection process and the train detection data calculation cost is high in the prior art are solved; the system can be used for subsequent foreign matter detection, train scratch detection, train track defect detection and the like, and the beneficial effects of reducing the data detection cost, improving the detection efficiency and ensuring
