Description

Technical Field

[0001] The present invention belongs to the technical field of detection methods and devices before and after hair transplantation, and specifically relates to an intelligent detection method for a head hair transplantation area and a head auxiliary detection system. Background Art

[0002] The accelerated pace of modern society and the increased pressure of life, frequent staying up late, nutritional imbalance, and the influence of genetic factors have caused an increasing number of people suffering from hair loss, with a general trend of younger people. In today's society where appearance is increasingly valued, the impact of baldness caused by hair loss on people's psychology is self-evident.

[0003] Hair transplantation is to take the hair follicles at the back of the human head as the source, separate them into single or multiple hair follicle units, and transplant them to the part that needs to be transplanted through fine microsurgery technology, so that they can survive and grow naturally in the new part, thereby achieving the purpose of repairing the local hair distribution density and achieving a beautiful effect. In fact, hair transplantation is also a kind of "taking money from Peter to pay Paul", which can achieve a concealed and visual effect of lush hair.

[0004] At present, the hair transplant industry mostly uses traditional optical magnifiers with lights, transparent films and marking pens to manually evaluate hair transplant plans through human visual observation and manual operation. The disadvantages are obvious. Not only is the operation cumbersome, but there is also a large human error, lack of accuracy and inability to effectively compare before and after. There is a lack of a product on the market that can assist in hair transplant surgery and can perform auxiliary testing and plan selection according to the hair transplant process, thereby improving the experience of hair transplant users and the success rate of hair transplantation.

DETAILED DESCRIPTION

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in combination with the drawings and the descriptions of the embodiments or the prior art. The following descriptions of the structures of the drawings are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0034] The technical solution provided by the present invention will be described in detail below by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0036] In addition, the technical features recorded in this article, or the steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can also be combined in any suitable manner in one or more embodiments. For those skilled in the art, it is easy to understand that the steps or operation sequence of the methods related to the embodiments provided herein can also be changed. Any order in the drawings and embodiments is only for illustrative purposes and does not imply a requirement to follow a certain order unless it is explicitly stated that a certain order is required.

[0037] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "connection" mentioned in this application include direct and indirect connections when they are reasonable and do not constitute self-contradiction.

[0038] Example 1

[0039] This embodiment designs an intelligent detection method for the hair transplant area on the head, including the following three steps S1, S2 and S3:

[0040] S1: Use auxiliary light to fill in the top, left, right and back of the human head.

[0041] In step S1, the auxiliary light used for fill light includes standard white light, ultraviolet light, cross-polarized light and / or parallel polarized light. The purpose of fill light is to facilitate the observation of the state of the scalp under different light, so as to facilitate the detection of the health of the scalp, the position of the hairline, the size of the hair follicle pores, etc.;

[0042] Among them, ultraviolet light supplement is used to detect the blockage of scalp hair follicles and oil secretion. Through these characteristics, it is convenient to intelligently match the health of scalp hair follicles, and it is convenient for doctors to give treatment suggestions and hair transplant period recommendations based on the health characteristics of the scalp.

[0043] The cross-polarized light fill-in can make the human head appear non-reflective and oil-free, reducing the impact of scalp oil on scalp detection. The cross-polarized light fill-in can reduce the interference of oil reflection on the doctor's judgment when the doctor is testing the status of hair follicles based on photos.

[0044] The fill light of parallel polarized light can make the human head appear reflective and oily, so that the taken photos can more clearly reflect the hair root texture and the changes in the redness and swelling of the hair follicles, thereby improving the accuracy of judging the health status of the scalp hair follicles based on the taken photos.

[0045] S2: Capture images of the top, left, right and back of the human head in different fill-light environments.

[0046] By collecting the top side image of the human head, the outline of the human head can be observed intuitively, and then, under the fill-in lighting of different auxiliary lights, the hairline position can be intelligently identified and outlined by comparing the color, degree of reflection, etc. of the hair area and the hairless area; at the same time, it is also necessary to detect and identify the left side, right side and back side of the top of the head respectively, so as to assist in determining the hairline position or the boundary position of the hair transplant area; since the images of the left side, right side and back side are collected, a three-dimensional human head shape can be obtained, which is convenient for intelligently matching the normal hairline position of a similar head shape, thereby improving the accuracy of the hair transplant area recognition range.

[0047] At the same time, after observing the top, left, right and back sides for image acquisition and establishing a three-dimensional model of the head, it is possible to give hair care suggestions based on the hairline position and hair thinning trend, and select the appropriate hair removal area for hair removal.

[0048] S3: Process the image and identify the human head contour, define the hairline according to the boundary of the hairy area of ​​the head, determine and define the hair transplantation boundary according to the contour position of the forehead, and the closed area between the hairline and the hair transplantation boundary is the hair transplantation area.

[0049] In step S3, the identified human head contour is a three-dimensional head model, and then the hair position distribution law of this head shape model is installed on the three-dimensional head model. The hair transplantation boundary is determined and delineated based on the contour position of the forehead. When the closed area between the hairline and the hair transplantation boundary is closed, it is the hair transplantation area.

[0050] The hair transplant area is displayed dynamically or statically through the display screen. The displayed image is mainly on the top side of the head, and the boundary of the hair transplant area can be manually adjusted and confirmed; the manual adjustment methods include overall zooming, overall dragging, left and right rotation or local movement of the hair transplant area boundary position; before the doctor confirms the hair transplant area through the display interface, a yellow line can be displayed at the boundary position of the hair transplant area on the head, and then a red line will be displayed after confirmation.

[0051] Example 2

[0052] After the hair transplant area is determined in Example 1, the method for calculating the number of hair transplants in the hair transplant area is as follows: the area of ​​the hair transplant area under the three-dimensional head model is calculated, and the hair transplant area is a curved surface area with the same shape as the top of the head; then, the bald patient can manually select the hair transplant density scheme to calculate the total number of hair transplants required. This makes it convenient for hair loss patients to choose a hair transplant scheme according to actual conditions and calculate the hair transplant cost; in addition, in this scheme, since the number of hair transplants can be calculated by a simple division operation, the hair transplant cost can be made more open and transparent during the calculation process.

[0053] At the same time, before calculating the total number of hair transplants required, since the number of hair follicles in the human scalp is constant, while the number of hair follicles on each person's head is different, the number of hair follicles can also be considered as the upper limit of the total number of hair transplants. Therefore, by detecting the number of hair follicles, or by being able to calculate the upper limit of the total number of hair transplants required based on the number of hair follicles identified in the hair transplant area collected in the image, the openness and transparency of the hair transplant process and the cost calculation process can be further improved.

[0054] Example 3

[0055] After the hair transplantation area is determined in Example 1, the intelligent AI unit can select the area according to the shape of the hair transplantation area to make hair models with different densities, different hair lengths and different hair growth directions in the database, paste the selected hair model into the hair transplantation area, and display the simulated effect after implantation on the display.

[0056] Example 4

[0058] The illumination unit can emit at least one auxiliary light and illuminate the top side, left side, right side or back side of the human head. The auxiliary light includes standard white light, ultraviolet light, cross-polarized light or / and parallel polarized light.

[0059] The image acquisition unit can acquire images of the top side, left side, right side or back side of the human head under different lighting conditions.

[0060] The intelligent AI unit can receive images collected by the image acquisition unit and use them for image processing, can identify the size and density of hair follicles and determine the health status of hair follicles, can locate the hair transplant area according to the hairline position and forehead contour position, or can generate different hair models to simulate the effect after hair transplantation; the boundary of the hair transplant area can be manually adjusted and confirmed; the manual adjustment method includes overall scaling, overall dragging, left and right rotation or partial movement of the boundary position of the hair transplant area; the hair model generates a hair transplant model through the color of the hair retained on the head and the selected different densities, different hair growth directions and different hair lengths. The hair transplant model is placed in the hair transplant area to form a virtual hair transplant effect diagram.

[0061] During the image processing process, the main focus is on identifying the color of the color blocks in the image and the distribution of continuous color blocks to identify the hair, hair follicle position and hair follicle size, etc. The size of the hair follicles, the color of the hair follicles and the degree of oil secretion of the hair follicles can be matched with the corresponding disease model in the database to determine the health of the scalp in the hair transplant area.
