acquiring a forehead part image of a patient to be transplanted, and determining a hair follicle implantation position from the forehead part image based on the target implantation density and the target implantation area.
As shown in fig. 1, in the above embodiment, the target transplantation area of the hair transplantation operation can be determined by obtaining the facial features of the patient to be transplanted, the target implantation density of the hair follicle implantation in the hair transplantation operation process is determined by the target transplantation area and the hair follicle density of the patient, then the hair follicle supply position for providing the implanted hair follicle in the hair transplantation operation can be determined according to the target implantation density and the retrooccipital region image, and the hair follicle implantation position of the hair follicle implantation is determined according to the target implantation density and the frontal head region image, so that the preoperative and intraoperative precise planning of the hair transplantation operation is realized, the hair transplantation operation is standardized and uniform, and the situations of uneven hair follicle acquisition density and uneven hair follicle implantation density are avoided.
Wherein, target hairline position mainly confirms according to the facial feature of treating the patient that plants hair, and its facial feature includes forehead width, actual hairline position, and after target hairline position was confirmed to finish, the target transplantation area of rethread facial feature and target hairline position among the definite patient hair transplantation operation process of treating the hair transplantation to can work out the target transplantation region that is fit for more treating patient's hairline position, shape and hair transplantation operation of planting hair transplantation.
In the existing hairline design of hair transplantation operation, the hairline design is usually designed based on the actual hairline, so that the hairline which accords with the head shape of a patient can be quickly designed, and the shape of the hairline after being designed can be matched with the shape of the original hairline.
However, when the actual hairline length of the patient to be implanted is not matched with the forehead width, hairline design is carried out according to the actual hairline of the patient to be implanted, the designed hairline length is smaller than the forehead width of the patient to be implanted, so that after the hair implantation operation of the patient to be implanted is completed, blank areas without hair transplanted at the two ends of the hairline appear, and the patient looks very sharp; the target hairline position and the target transplanting area are determined according to the facial features of the patient to be implanted, the actual hairline suitable for the patient to be implanted can be well designed when the condition that the actual hairline length of the patient to be implanted is not matched with the forehead width is generated, and after the hair implantation operation, the blank areas where hair is not transplanted cannot be generated at the two ends of the hairline, so that the hair transplanting device looks more attractive.
Optionally, the obtaining of the forehead width, the actual hairline position and the target hairline position after hair implantation according to the facial features of the patient to be implanted includes:
acquiring a picture before an operation of a patient to be transplanted, and constructing a feature recognition model according to the picture before the operation;
and identifying the facial features of the patient to be implanted through the feature identification model, and acquiring the forehead width, the actual hairline position and the target hairline position after hair implantation of the patient to be implanted according to the facial features.
As shown in the first step of fig. 2, in the above embodiment, a feature recognition model for recognizing the hair line and the facial features of a patient may be constructed by collecting and organizing the preoperative pictures of a hair loss patient, selecting a common feature recognition model in the existing research, and training the feature recognition model by using the obtained preoperative pictures, where the feature recognition model may recognize the existing height of the hair line and the shape of the hair line of the hair loss patient (the height of the hair line refers to the distance between the hair line and the eyebrow arch), and when the model recognizes that the existing hair line shape is a "W" shape, the recognized shape of the hair line may be preferentially used as the shape of the hair line during the planning of the hair line position, so that the planned shape of the hair line conforms to the existing shape of the hair line of the patient as much as possible; the model can identify the position of the eyebrow arch of the alopecia patient when identifying the existing hairline height of the patient, so as to calculate the height of the hairline and the hairline distance needing transplanting (the hairline distance is the distance from the existing hairline to the planned hairline). After the characteristic identification model is built, the facial features and the actual hairline position of a patient to be implanted can be quickly identified by the model, meanwhile, according to the existing documents and the common design scheme of hair implantation operation, the hairline position of the patient after hair implantation operation can be determined, the hairline position is used as the target hairline position, the model is trained in the characteristic identification model which is well built by guiding the target hairline position, the characteristic identification model can be used for simultaneously planning the target hairline position when identifying the facial features and the actual hairline position of the patient, and therefore a doctor is helped to determine the hair follicle transplantation range of the hair implantation operation.
It should be further noted that, for the patient to be implanted, the hairs at the temple also belong to the area where the hair loss phenomenon easily occurs, that is, the hairs at the two ends of the hairline are also easy to lose hair, which causes the areas at the two ends of the actual hairline to extend backwards to the brain, at this time, if the hairline design is performed only according to the actual hairline, under the condition that the hairs at the temple are not seriously lost, the two ends of the hairline extend backwards to the brain after the hair implantation occurs, thereby affecting the beauty; design the hairline through facial feature, can come the position of fixed value hair line after the hair is planted according to the forehead width that the patient is different, and the hair of temple department drops and can not be to the influence of hairline design, and the hairline after the design is also more pleasing to the eye, avoids the condition emergence of extension behind the hair line both ends after planting the hair to the brain.
Aiming at the planning of the hairline position, the obtained facial features of the patient to be implanted and the actual hairline position can be displayed on a display screen, after the actual hairline position is automatically identified, the effect that the hairline shape is shifted to the position 8cm above the eyebrow arch is calculated, and the effect is marked on the image of the display screen in the form of a fluorescent solid line.
Meanwhile, the target hairline position can be customized according to the requirements of the patient, for example, the shape, height and angle of the hairline are designed comprehensively, and here, the design is only an example and is not limited.
Optionally, the determining a target transplantation area according to the forehead width, the actual hairline position and the target hairline position includes:
determining a hairline distance according to the actual hairline position and the target hairline position;
the target transplantation area was determined by multiplying the hairline distance by the forehead width.
As shown in the second step of fig. 2, in the above embodiment, the target transplantation area is the area in which hair follicles need to be implanted during hair transplantation, the target transplantation area during hair transplantation can be regarded as a rectangle, the forehead width is regarded as the long side of the rectangle, and the distance between the actual hairline and the target hairline, i.e., the hairline distance, is regarded as the wide side of the rectangle, so that the area value of the target transplantation area can be obtained by the calculation formula of the rectangle area, i.e., the forehead width (cm) x the hairline distance (cm).
Optionally, the determining the target implantation density based on the hair follicle concentration and the number of hairs in the unit of hair follicles comprises:
when the number of hairs in the unit of hair follicles is greater than 1 and less than or equal to 3, the target implantation density is equal to the follicular concentration;
when the number of hairs in the unit of hair follicles is less than or equal to 1, the target implantation density is equal to twice the follicular concentration.
In the above embodiment, for the planning of the hair density of the transplantation site, the implantation density of the hair follicle is mainly determined by the density of the existing hair, and if the original hair is sparse, that is, the number of hairs in a unit hair follicle is less than or equal to 1, the target implantation density of the hair follicle in the hair transplantation operation is generated twice according to the original hair follicle density of the patient to be transplanted; if the original hair density is normal, namely the number of hairs in a unit hair follicle is 1-3, generating the target implantation density with the same density according to the original hair follicle density of the patient to be transplanted.
Optionally, the determining a hair follicle supply position from the occipital posterior area image based on the target implantation density and the target implantation area includes:
determining a hair follicle supply region in the occipital posterior region image according to the target transplantation area;
determining a follicular delivery location in the follicular delivery area according to the target implantation density;
the hair follicle supply positions are arranged in a checkerboard point shape.

According to the above embodiment, in a normal situation, when a hair loss patient performs a hair transplantation operation, a person with a relatively light hair loss degree needs about 100 hair follicles during the hair transplantation operation, and the transplantation area is about one square centimeter, when the hair loss degree of the hair loss patient is heavy, and a forehead hair line retreats or a vertex is sparse and obvious, about 2000 to 3000 hair follicles are needed during the hair transplantation operation, when the hair loss degree of the hair loss patient is severe, 5000 hair follicles are needed, and the transplantation area of the hair transplantation operation is about 50 square centimeters; during hair transplantation operation, the part implanted into hair follicle extends from the original hairline of the alopecia patient to the eyebrow arch, so that the transplanting effect is more natural and the hair is integrated with the original hair. The selected supply area of hair follicles is generally in the neck and occipital region, where hair follicles have no androgen receptor and thus are not affected by androgen and can maintain normal physiological characteristics of hair growth, so called "permanent hair".
Optionally, the determining a hair follicle implantation position from the forehead head position image based on the target implantation density and the target implantation area includes:
determining a hair follicle implantation area in the forehead position image according to the target transplantation area;
determining a hair follicle implantation position in the hair follicle implantation area according to the target implantation density;
the hair follicle implantation positions are arranged in a checkerboard point shape.
As shown in the fourth step of fig. 2, in the above embodiment, by capturing the forehead image of the patient to be transplanted, uploading the forehead image to the display screen, and determining the hair follicle implantation area for performing the hair transplantation operation on the forehead image according to the size of the target transplantation area, the hair follicle implantation area is identified in the occipital region image on the display screen in the form of a fluorescent solid line, and an appropriate hair follicle implantation position is determined in the hair follicle implantation area according to the target implantation density to guide the doctor to perform hair follicle implantation.
