VIN Verification

Let's begin by introducing a VIN verification function that filters out unnecessary text from the image. There are two primary methods to verify if the text is a VIN and determine its validity. According to Wikipedia, the first method involves calculating the check digit within the VIN itself. However, it's important to note that this technique is applicable only to vehicles from North America.

transliteration_map = {
    'A': 1, 'B': 2, 'C': 3, 'D': 4, 'E': 5, 'F': 6, 'G': 7, 'H': 8,
    'J': 1, 'K': 2, 'L': 3, 'M': 4, 'N': 5, 'P': 7,'R': 9,
    'S': 2, 'T': 3, 'U': 4, 'V': 5, 'W': 6, 'X': 7, 'Y': 8, 'Z': 9
}
weight_factor = [8, 7, 6, 5, 4, 3, 2, 10, 0, 9, 8, 7, 6, 5, 4, 3, 2]

def verify_vin(vin: str):
    if len(vin) != 17:
        return False
    transliterated = [int(char) if char.isnumeric()
                      else transliteration_map[char]
                      for char in vin]
    products = [transliterated[i] * weight_factor[i] for i in range(17)]
    num = sum(products) % 11
    checkdigit = 'X' if num == 10 else str(num)
    return checkdigit == vin[8]
Enter fullscreen mode Exit fullscreen mode

While the first method might not be universally applicable, do not worry, as we have a second method that offers a reliable alternative. VINs are 17-character strings with a specific format that excludes the letters O (o), I (i), and Q (q). Thus, the second method involves validating these rules using regular expressions. In this tutorial, we will use the second method, but you can choose either method or even combine them for enhanced accuracy.

def verify_vin(vin: str):
    """Verify that string is VIN."""
    pattern = r'^[A-HJ-NPR-Z\d]{11}\d{6}$'
    return bool(re.match(pattern, vin))
Enter fullscreen mode Exit fullscreen mode

Text Recognition

As previously determined, we will use the OCR API to detect a VIN in photos. This powerful tool simplifies the process, ensuring both accuracy and efficiency. You simply send an image to the API, receive the text in response, and filter out any text that does not contain the VIN. By following these steps, you can easily extract the necessary information and discard any irrelevant data, making the process straightforward and effective. This method not only saves time but also improves the accuracy of VIN recognition, which is essential for maintaining accurate vehicle records and complying with legal requirements.
