The Vehicle Identiﬁcation Number (VIN) or chassis number, as it is sometimes known, is a unique identiﬁcation number for every car manufactured. An OCR code is printed on each Engine which contains all the details necessary. By using an advanced OCR technology based camera system; it is possible to read characters on the engine unit. Reading the OCR helps the user to move the required engine to the appropriate location for assembling. The alpha numeric characters on the engine assembly can be read with the dedicated tool provided in the software known as the OCR tool. Despite engines having a shiny surface, the OCR can be detected with relative ease as suitable illumination will be providing to counter the effect.
