Reliable face billing method in hospital

Abstract

The invention relates to a reliable hospital face check-out method. The method comprises the following steps: running a reliable hospital face check-out mechanism to carry out face check-out. The reliable hospital face check-out mechanism comprises an information prompting device arranged on a hospital check-out table for displaying the deviation angle on the spot when receiving the deviation angle; A content grabbing device is arranged on a checkout table of a hospital, and is used for acquiring image content in front of a checkout requestor to output a corresponding checkout image; An equalization degree extracting device connected with the content capturing device, configured to receive the checkout person image, detect the gray level equalization degree of the checkout person image toobtain the current equalization degree corresponding to the checkout person image, and output the current equalization degree corresponding to the checkout person image; The checkout execution deviceis configured to recognize facial features corresponding to facial contours when the received deviation angle does not exceed a limit, and perform on-site checkout operation based on an electronic account corresponding to the facial features.

Description

Technical field [0001] The invention relates to the field of facial payment, in particular to a reliable hospital facial checkout method. 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 cropped out, and after preprocessing, it is fed into the back-end recognition algorithm. The recognition algorithm must complete the extraction of facial features and compare it with the known faces in the inventory to complete the final classification. Summary of the invention [0003] In order to solve the current technical problem of the low level of automation of medical payment, the present invention provides a reliable hospital face checkout method, which determines whether the face checkout operation can be performed based on the angle of the recognized facial contour deviating from the vertical plane, and the angle reaches a preset range The internal time side allows the face checkout...

Problems solved by technology

[0003] In order to solve the technical problem of the current low level of medical payment automation, the present invention provides a reliable face checkout method in a hospital, which determines whether the face checkout operation can be performed based on the angle at which the recognized facial contour deviates from the vertical plane, and when the angle reaches the preset range Facial checkout operations are allowed within the time limit, otherwise, on-site reminders are provided, which not only improves the efficiency of hospital checkout, but also ensures the reliability of hospital checkout; and selects the corresponding mean value filter window based on the distribution of each spot area in the image , and within the average filter 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
