Logistics station license plate recognition method

The invention relates to a logistics station license plate recognition method. The method comprises the following steps: acquiring a snapshot image with a marking box; inputting the snapshot image into a license plate position detection model to obtain a first output result; judging whether the area proportion of the license plate image in the marking box is greater than a first preset threshold value or not according to the position coordinates in the first output result; if yes, intercepting a license plate image and inputting the license plate image into a pre-constructed license plate definition classification model to obtain a second output result; if the definition type in the second output result is clear and the first confidence value is greater than a second preset threshold, determining that the license plate image is a to-be-recognized image; when a preset number of to-be-recognized images are obtained, horizontally splicing the to-be-recognized images into a target license plate image, and inputti
