[0002] The access control system is an important part of modern security management. It controls the entry and exit of personnel in specific areas through various technical means. Facial recognition technology is an advanced technology in the access control system. It verifies identities by recognizing facial features, thus realizing contactless access control. However, in practical applications, facial recognition technology may be affected by various factors. One of them is direct sunlight. Strong direct sunlight may cause the images captured by the camera to be overexposed, that is, the brightness in the images is too high, which will cause the details of the face to be lost, affecting the accuracy of the recognition system. At the same time, due to the high installation position of the access control, it is very difficult for children with relatively short heights to use. Content of the Utility Model
