Hospital facial checkout system

Abstract

The present invention relates to a facial checkout system in a hospital, comprising: an information prompt device, which is set on the checkout counter of the hospital, and is used to display the deviation angle on the spot when receiving the deviation angle; a content grabbing device, which is set up on the hospital checkout On the stage, it is used to acquire the image content of the checkout requester to output the corresponding checkout person image; the balance degree extraction device is connected to the content capture device, and is used to receive the checkout person image, and the checkout person image The gray balance degree of the person image is detected to obtain the current balance degree corresponding to the checkout person image, and output the current balance degree corresponding to the checkout person image; the checkout execution device is used to receive the deviation angle not exceeding When the limit is limited, the facial features corresponding to the facial contours are identified, and the on-site checkout action is performed based on the electronic account corresponding to the facial features. Through the invention, the payment efficiency of medical expenses is accelerated.

Description

technical field [0001] The invention relates to the field of facial payment, in particular to a hospital facial checkout system. Background technique [0002] Facial feature detection After detecting the face and locating the key feature points of the face, the main face area can be cut out, and after preprocessing, it is fed into the back-end recognition algorithm. The recognition algorithm needs to complete the extraction of facial features and compare them with the known faces in the inventory to complete the final classification. Contents of the invention [0003] In order to solve the technical problem of the current low level of medical payment automation, the present invention provides a hospital facial checkout system, which determines whether facial checkout operations can be performed based on the angle at which the recognized facial contour deviates from the vertical plane, and when the angle reaches a preset range The party allows face checkout operations, oth...

[0003] In order to solve the technical problem of the current low level of medical payment automation, the present invention provides a hospital facial checkout system, which determines whether facial checkout operations can be performed based on the angle at which the recognized facial contour deviates from the vertical plane, and when the angle reaches a preset range The party allows face checkout operations, otherwise, an on-site reminder is given to ensure the reliability of hospital checkout while improving the efficiency of hospital checkout; and based on the distribution of each spot area in the image, select the corresponding mean value filter window, and In the average filtering window centered on the pixel of the image, the closer to the pixel of the image, the greater the weight coefficient, which improves the filtering effect of the image signal
