System for authenticating remote driver in real time using image and artificial intelligence

A system for authenticating a remote driver in real time, the system comprising:

• a face detection unit mounted on construction equipment to detect a face of a driver on board;
• a remote control station configured to transmit facial data of the driver on board detected through the face detection unit to an authentication unit, receive a driver information search result and an authentication determination result from the authentication unit, and start the construction equipment;
• and
• the authentication unit configured to search for the facial data of the driver on board received from the remote control station from driver information data stored in a database and transmit the driver information search result and the authentication determination result to the remote control station,
• the authentication unit includes:
• an authentication system unit configured to pre-process the facial data of the driver transmitted from the face detection unit, and then encode the pre-processed data and transmit the encoded pre-processed data to an authentication service unit;
• the authentication service unit configured to decode the pre-processed data received from the authentication system unit, and then retrieve learned data to extract a driver key value and search driver information stored in the database, determine whether to authenticate based on a result of searching the driver information from the database, and transmit an authentication determination result to the remote control station;
• and
• a control unit configured to receive a login execution signal from the remote control station according to the authentication determination result received from the authentication service unit and then transmit a driving signal of the construction equipment to the remote control station,
• a registration system unit configured to pre-process the facial data of the driver on board transmitted from the face detection unit, and then encode the pre-processed data and transmit the encoded pre-processed data to a registration service unit;
• and
• the registration service unit configured to decode the pre-processed data received from the registration system unit and then learn the facial data of the driver to create driver data, and transmit the created driver data to the authentication service unit,
• wherein the authentication service unit registers the driver data received from the registration service unit in the database,
• wherein the authentication unit is configured to:
• detect a face area using a local binary pattern (LBP)-based detector from the facial data of the driver on board transmitted from the face detection unit, and discriminate presence or absence of a face in the detected face area using a cascade classifier, and is controlled by:
• a face pre-processing process in which a feature detection process, a geometric transformation and cropping process, a histogram equalization process, a noise control process, and an image normalization process are sequentially performed;
• a face data collection and training data creating process in which a specified number of image samples generated through the face pre-processing process are collected and labels are assigned to the database and the database is classified, and the classified database is trained to create data;
• and
• a face recognition and authentication granting process in which, with respect to a face image transmitted from the remote control station upon a request for real-time authentication, a labeled driver identification key corresponding to a class number is extracted using a discriminator running in the authentication service unit, a similarity between the face image currently transmitted from the remote control station and training data is determined, and when a criterion is satisfied, user information in the database is searched for and a result of searching the user information is transmitted to the remote control station, and the remote control station that has completed authentication granting logs in to the construction equipment to complete an authentication procedure.
