The annotations are included in txt files in the labels/ folder, whose file names are the same as the names of the corresponding images. In the txt file, each line denotes a LP in the images. The format of the annotation of one LP is:

x1, y1, x2, y2, x3, y3, x4, y4, type, content

The first eight numbers represent the coordinates of the bounding quadrilateral corners. The "type" annotation represents the type of the LP, 0 for blue plates, 1 for yellow and single-line plates, 2 for yellow and double-lines plates, 3 for white plates. The "content" annotation represents the LP content.
