[0002] The integrated information collection equipment is a hardware device of the integrated personnel basic information collection system. This collection device can usually realize many functions such as computer, mobile phone information collection device, finger (palm) print collection device, second-generation ID card reader, DNA collection special drawer (cabinet), drying box, barcode reader, printer, barcode printer, portrait collection, etc., and can realize comprehensive and accurate personnel information collection with the matching software system;
[0003] However, in transaction supervision activities, there are often situations where people need to change their identity information. Although there is a department dedicated to information change, people usually tend to understand the situation through the paths they are familiar with. Therefore, some people in need will go to the registration office for help, but because the existing equipment does not have the ability to verify the change, they are told that they need to go elsewhere to solve the problem, which is very inconvenient;
[0004] The identity of a person is authenticated through facial recognition, which is cumbersome. Repeated facial recognition increases the computing burden of the processor, which may cause the device to heat up and performance to degrade. Each recognition generates a large amount of image data and feature information. Repeated execution will quickly occupy the storage space. The pupil position is not determined, and iris feature comparison is performed directly, resulting in inaccurate division of the iris area, which in turn affects the integrity and accuracy of feature extraction.

The electrical signal of the touch input module 4 is translated into a digital signal by the transcriber 8, and then enters the control module 2, and then is stored in the database. After the identity information is input, the personnel are guided to stand on the weighing device on the collection module 5, and then the personnel are guided to stand straight, and then the collection module 5 is started, the weighing device will collect the weight information of the personnel, and the motor 13 is started at the same time, thereby driving the pressing plate 15 to descend through the threaded rod 14 until the pressing plate 15 touches the top of the person's head, and then collects the person's height information. The electrical signal of the collection module 5 will enter the control module 2 through the wire and then be stored in the database. Moreover, when the pressure plate 15 touches the user's head, it can send a signal to the control module 2 inside the equipment box 1, and the control module 2 stops driving the motor 13, and controls the cooperation between the motor 13 and the threaded rod 14 to drive the pressure plate 15 to rise and reset. When a person needs to change the information, the person is guided to input the verification information by touching the input module 4. The verification module 6 quickly calls the information in the database for identity authentication, and then re-enters the information to complete the information change.

If , then the image block containing the second label is recorded as the eye image block; the row number and column number The corresponding position is the center of the eye socket. Taking the center of the eye socket as the base point, extend to both sides to compare the grayscale values and determine the position distribution of the pupil and the white of the eye. Then focus on the pupil position, collect the pupil data of the guide, and compare it with the iris data in the iris feature template database of legal persons pre-entered in the device. The currently collected and generated iris feature code is compared with the template in the database one by one, and the similarity between the two is calculated. If the similarity between the two reaches the preset threshold, it is determined to be a successful match, confirming that the identity of the person is consistent with the corresponding identity in the database, generating a change signal, and passing the change signal to the change module; otherwise, it is determined that the identity does not match and re-detection is required.
