Generate Synthetic Korea License Plate.

• You can use this generator when there is insufficient data on the license plate.

• This image generator may be used in a character recognition model like 'CRNN'

• I recommend pre-training with synthetic images and fine-tune with real data.

Types of Korean license plates

• You can create synthetic license plate pictures by selecting the plate of the desired type.

Type 6

Type 7 (electric vehicle license plate)

Labeling

• The name of the photo shows the letters and numbers on the license plate.

• Hangul in the plate was translated into English with the following rules.

• Region : 서울 -> A, 인천 -> B ...
  

• Hangul : 나 -> sk, 너 -> sj, 다 -> ek, 도 -> eh ...
  

Brightness control part

def random_bright(img):
    img = cv2.cvtColor(img, cv2.COLOR_RGB2HSV)
    img = np.array(img, dtype=np.float64)
    random_bright = .5 + np.random.uniform()
    img[:, :, 2] = img[:, :, 2] * random_bright
    img[:, :, 2][img[:, :, 2] > 255] = 255
    img = np.array(img, dtype=np.uint8)
    img = cv2.cvtColor(img, cv2.COLOR_HSV2RGB)
    return img
