Embodiment Construction
[0026] For the convenience of describing the content of the embodiment, some terms are first described here:
[0027] Flexible template that meets license plate standards: The character area of the 07-style license plate in my country consists of 7 characters and 1 spacer. The standard outline size of a single-line car license plate: length 440mm and width 140mm; the total length of license plate characters is 409mm, the uniform width of a single character is 45mm, and the height is 90mm; the distance between the second and third characters is 34mm, and the distance between other characters is 12mm; The spacer is 10mm wide, the distance between the second and third characters and the spacer is 12mm; the stroke width is 10mm. According to the proportional relationship between each character and the character interval in the license plate standard, a binary series represented by "0, 1" is generated as a standard license plate template. Since license plates vary in scale in th...
