The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a method for determining an age of an individual based on morphological developmental characteristics of a cranial surface of a juvenile may include:
and S100, obtaining a cranium surface morphological development characteristic image of the user.
Wherein, the skull surface morphological development characteristic image is a surface morphological image of the skull in the human body growth and development process. Alternatively, the cranium defined for the human body according to international anatomical terms includes a cranium and a cranium, wherein the facial morphology of the cranium and the cranium is characterized in that the upper posterior part divided by a line connecting the upper edge of the orbit and the upper edge of the external auditory meatus is the cranium, and the lower anterior part is the cranium. Wherein the surface morphology features include the length, width, size of the area of the different regions, size of the depressions and projections, etc. in proportional relationship.
Alternatively, the facial morphological features of the skull may include features of the five sense organs, chin, forehead and cheeks. The surface morphology features of the cranium may include features such as a contour of the cranium.
Morphology, also known as human morphology, refers to the external shape and characteristics of the body that are expressed at different stages during growth and development due to the combined action of both innate inheritance and acquired environment factors. Body morphology is generally represented by length, width, girth, weight, area, and their interrelationship. The overall development law is that the development of the disease is irreversible from immature to gradually mature and aging (degeneration).
Optionally, the morphological development characteristic image of the skull surface can be a two-dimensional plane image or a three-dimensional model image. It should be noted that the image of morphological developmental features of the cranial surface is not an image of the bone of the head. Alternatively, the morphological developmental feature image of the cranial surface may be as shown in fig. 2.
Optionally, in the embodiment of the present invention, the image acquisition device (such as a mobile phone or a digital camera) may acquire and obtain the cranium surface morphological development feature image of the user, or extract and obtain the cranium surface morphological development feature image of the user from a storage medium storing the cranium surface morphological development feature image of the user.
Optionally, the skull surface morphological development feature image of the user may be an image obtained by performing preset image standardization preprocessing on an original skull image of the user.
Optionally, the preset image standardization processing may be to correct the original cranial image of the user according to a preset human face standardization correction algorithm to obtain a corrected cranial surface morphological development characteristic image. Optionally, the skull surface morphological development feature image of the user may be an image that meets a preset posture standard and/or a preset image quality standard. Optionally, the face normalization correction algorithm may include a face image geometry correction algorithm and/or a face image quality correction algorithm. Optionally, in the embodiment of the present invention, the original cranial image of the user may be subjected to 3D matching and/or 3D rotation by using a face image geometric correction algorithm, so as to perform posture standard correction on the original cranial image of the user, so that the obtained cranial surface morphological development feature image meets a preset posture standard. Optionally, in the embodiment of the present invention, the original cranial image of the user may be subjected to noise point removal, illumination influence removal, contrast adjustment, sharpness adjustment, and other processing by using a human face image quality correction algorithm, so as to perform standardized correction on the image quality of the original cranial image of the user, so that the obtained cranial surface morphological development feature image meets a preset image quality standard.
Optionally, the preset image normalization processing may also be performed by determining correction auxiliary points on an original cranial image of the user, and performing posture standard correction on the original cranial image according to the correction auxiliary points to obtain a corrected cranial surface morphological development feature image, so that the obtained cranial surface morphological development feature image meets a preset posture standard. Optionally, the preset posture standard may be that the pupil positions on the morphological development feature image of the skull surface are located at the same horizontal coordinate. Alternatively, the correction auxiliary points may be two mouth point points and two pupil points. Specifically, the preset image normalization processing may specifically be to determine two pupil points and two pupil points in the original skull image, determine a first midpoint of a connecting line between the two pupil points and a second midpoint of a connecting line between the two pupil points, then determine a third midpoint of a connecting line between the first midpoint and the second midpoint, and rotate the original skull image with the third midpoint as a fixed point until the two pupil points are located at the same horizontal coordinate.
Optionally, the preset image normalization processing may further include image processing such as performing equal-scale magnification, reduction, translation, rotation, cropping, and matting on the original skull image of the user. The embodiment of the invention can also set the resolution of the cranial surface morphological development characteristic image in the preset image standardization process, so that the cranial surface morphological development characteristic image obtained by the embodiment of the invention has fixed resolution. It is to be understood that the specific preset image normalization processing procedure can be set by a relevant technician according to actual needs, and the embodiment of the present invention is not further limited herein.
S200, inputting the cranium surface morphological development characteristic image into a preset cranium characteristic information determination model, and obtaining at least one cranium characteristic information output by the cranium characteristic information determination model.
Wherein, the cranial feature information determination model can be a convolutional neural network model. The embodiment of the invention can train the cranial feature information determination model in advance, so that the cranial feature information determination model can determine cranial feature information of a cranial surface morphological development feature image. Optionally, the cranial feature information may be feature data reflecting a growth rule of a human body in the morphological development feature image of the cranial surface.
Alternatively, based on the method shown in fig. 1, as shown in fig. 3, another method for determining the developmental age of an individual based on the morphological developmental characteristics of the cranial surface of a juvenile of the child according to the embodiment of the present invention may include:
s210, inputting the cranium surface morphological development characteristic image into a preset cranium characteristic information determination model so that the cranium characteristic information determination model determines at least two preset cranium key points in the cranium surface morphological development characteristic image, and determining and outputting at least one cranium characteristic information according to the at least two preset cranium key points.
Specifically, in the embodiment of the present invention, the cranial feature information determination model may be subjected to machine learning by using the cranial training image with the preset cranial key points marked in advance, so that the cranial feature information determination model may determine the positions of the preset cranial key points in the cranial surface morphological development feature image, and calculate and obtain the cranial feature information according to the preset cranial key points corresponding to each preset item of data capable of reflecting the growth and development rules of the human body, thereby outputting the cranial feature information capable of reflecting the growth and development rules of the human body. According to the embodiment of the invention, the skull feature information reflecting the growth and development rule of the human body in the skull surface morphological development feature image can be accurately determined through the preset skull feature information determination model.
The applicant of the present invention finds out: under normal conditions, because the skull belongs to a part of a human body, based on the craniocaudal law and the centripetal law followed by the growth and development of the human body, the skull of the human body has skull characteristic information capable of reflecting the growth and development law of the human body in the growth and development process of the human body. For example: in the growth and development process of a human body, longitudinal growth and transverse growth of craniums at different development ages are in unequal proportion, and specifically, the growth amplitude of cranium feature information related to longitudinal growth of the cranium is different from that of cranium feature information related to transverse growth of the cranium, so that the proportion between the cranium feature information related to longitudinal growth of the cranium and the cranium feature information related to transverse growth of the cranium is different in change rule. Therefore, the embodiment of the present invention can determine the development age of the human body based on the above research findings through the cranial feature information on the cranial surface morphological development feature image.
In order to accurately obtain the cranial feature information, the embodiment of the invention can preset cranial key points related to the growth and development rule of the human body. Optionally, the preset skull key points may include an glabellar point, a hair flange point, a pupil point, a nasal wing point, a infraorbital point, an infranasal point, an oral angle point, a submental point, a nasal bridge point, an intraocular angle point, and an extraocular angle point.
To facilitate intuitive understanding of the pre-determined cranial key points, the following is described with reference to fig. 4: the glabellar point is the point at the lower part of the forehead, above the nasion, where the bulge between the two eyebrows is most prominent forward on the median sagittal plane. The limbal point may be the intersection of the forehead limbus with the midsagittal plane. The pupil point may be a pupil center point. The alar point may be an alar outermost point. The infraorbital point may be the lowest point of the infraorbital margin. The infranasal point may be the deepest point of the angle formed by the septum in the nose and the skin of the upper lip, in the midsagittal plane. The corner of the mouth may be the point at which the upper and lower lip mucosal edges meet at the outboard end of the cleft. The submental point may be the lowest point of the chin in the positive midsagittal plane when the head is positioned in the eye-ear plane. The nose bridge point may be the most concave part of the upper end of the nose, i.e. the turning part of the back of the nose and the forehead, when the head is in the plane of the eyes and ears. The angular point in the eye may be the point on the internal angle of the cleft where the upper and lower eyelid margins meet. The external corner point may be the point at which the upper and lower eyelid margins meet at the external corner of the fissure.
It is noted that, in a typical case, there are two pupil points, nasal ala points, infraorbital points, angular points of the mouth, angular points of the eyes, and angular points of the eyes outside. For example: the pupillary points may include a left pupillary point and a right pupillary point.
It is understood that, in the embodiments of the present invention, a part of the glabellar point, the limbus point, the pupil point, the nasal wing point, the infraorbital point, the subnasal point, the oral angle point, the submental point, the nasal bridge point, the intra-ocular angle point, and the extraocular angle point may be selected as the preset cranial key point.
Optionally, the cranial feature information may include a longitudinal axis length and/or a transverse axis width between two preset cranial key points, and/or graphic information formed by connecting more than three preset cranial key points, where the graphic information includes a graphic area and an angle inside a graphic.
Wherein the longitudinal axis is parallel to the median sagittal facial line of the human body, and the transverse axis is perpendicular to the median sagittal facial line of the human body. The embodiment of the invention can obtain the length of the longitudinal axis and/or the width of the transverse axis between any two preset cranial key points. Alternatively, the longitudinal axis length may be the distance between two predetermined cranial keypoints in the longitudinal axis direction, and the transverse axis width may be the distance between two predetermined cranial keypoints in the transverse axis direction. For example: as shown in fig. 5, the length of the vertical axis between the inter-brow point and the infranasal point is 196 pixels, the width of the horizontal axis between the inter-brow point and the infranasal point is 0 pixel, the length of the vertical axis between the inter-brow point and the left oral corner point is 308 pixels, and the width of the horizontal axis between the inter-brow point and the left oral corner point is 154 pixels. It is understood that fig. 5 is only a schematic diagram, and that in addition to the points of the glabellar, infranasal and oral corners, embodiments of the present invention may also achieve other longitudinal axis lengths and/or transverse axis widths between two predetermined cranial key points.
The embodiment of the invention can preset more than three preset cranium key points for connecting and forming the graphic information. And determining the graph area and the graph internal angle in the graph information through the graph information formed by connecting the more than three preset cranial key points. For example: as shown in fig. 6, the embodiment of the present invention may form a triangle by connecting the glabellar point and the two corner points, the area of the triangle is the area of the shaded portion, and the sum of the three angles inside the triangle is 180 degrees. It can be understood that fig. 6 is a schematic diagram, and besides that the connection between the glabellar point and the two corner points forms a triangle, the embodiment of the present invention may also determine the area of the graph and the internal angle of the graph in the graph information by using the graph information formed by connecting more than three preset cranial key points. For example: the embodiment of the invention can obtain the parallelogram formed by connecting the two pupil points and the two nasal wing points, and determine the angles of the four corners inside the parallelogram and the area of the parallelogram.
Optionally, the cranial feature information may further include head circumference information.
According to the embodiment of the invention, the cranial feature information reflecting the growth and development rule of the human body can be accurately determined through the preset cranial key points associated with the growth and development rule of the human body, so that the result of subsequently determining the development age is more accurate.
S300, inputting the information of the at least one cranial feature into a preset development age determination model, and obtaining the development age which is output by the development age determination model and matched with the morphological development feature image of the cranial surface.
Wherein, the preset development age determination model may be a convolutional neural network model. Optionally, as shown in fig. 7, the training process of a developmental age determination model provided in an embodiment of the present invention may include:
s10, obtaining at least one cranial feature information corresponding to the cranial training image, wherein the at least one cranial feature information is marked with a development age matched with the cranial training image.
Specifically, in the embodiment of the present invention, at least one image of a skull of a human body may be collected in advance as a skull training image, and a development age corresponding to the human body is labeled in the skull training image, so that the obtained skull feature information corresponding to the skull training image is also labeled with the development age. For example: according to the embodiment of the invention, the image of the three-part cranium can be shot to be used as the cranium training image, the hand skeleton image of the three-part cranium is shot, the development age of the three-part cranium is determined from the hand skeleton image of the three-part cranium, the development age of the three-part cranium is labeled to the cranium training image corresponding to the three-part cranium, and the cranium training image labeled with the development age of the three-part cranium is used for training the development age determination model. It should be noted that the time for acquiring the skull training image and the time for acquiring the hand skeleton image should be within a preset time interval. For example: the time for collecting the three-zhang skull training image and the time interval for collecting the three-zhang hand skeleton image are within the preset time interval. Alternatively, the preset time interval may be 1 minute, 1 hour, 1 day, and 1 month.
S20, performing machine learning on the at least one cranium feature information to obtain the developmental age determination model, wherein the developmental age determination model has the following inputs: and the cranial feature information corresponding to the morphological development feature image of the cranial surface, and the output of the development age determination model is as follows: and the development age matched with the morphological development characteristic image of the skull surface.
Optionally, in the embodiment of the present invention, an image of a skull of a human body corresponding to the target human body information may be selected as the skull training image. Alternatively, the target human body information may include at least one of gender, region, calendar age, height, weight, nationality, city, urban-rural union, and rural area. For example: in the embodiment of the invention, only the image of the cranium of the human body with the gender of a male can be used as the cranium training image, and the image of the cranium of the human body with the region of Yunnan and the calendar age of 14 can also be used as the cranium training image. It is to be understood that, when an image of a skull of a human body corresponding to the target human body information is selected as the skull training image, the trained developmental age determination model may be exclusively used to determine the developmental age of the user corresponding to the target human body information.
The development age can accurately reflect the growth and development level and the maturity of the human body, and is an objective index for evaluating the growth and development rule of the human body. Alternatively, the developmental age may comprise bone age and/or tooth age. The bone age is the abbreviation of bone age, and the development degree of the bone is mainly judged according to the state of maturity change in the bone development process (calcification, formation of ossification center, deformation of the ossification center and the degree of metaphyseal healing of the ossification center).
Alternatively, based on the method shown in fig. 1, as shown in fig. 8, another method for determining the developmental age of an individual based on the morphological developmental characteristics of the cranial surface of a juvenile of the child according to the embodiment of the present invention may include:
s310, inputting the at least one cranial feature information into a preset development age determination model, so that the development age determination model determines and outputs a development age matched with the cranial surface morphological development feature image according to the at least one cranial feature information and/or the proportional relation among different cranial feature information.
It can be understood that, in the training process of the model for determining the developmental age, the embodiment of the present invention may obtain a proportional relationship between different cranial feature information, perform machine learning on the proportional relationship, and determine a corresponding relationship between the proportional relationship and the developmental age, so that the obtained model for determining the developmental age has a function of determining the developmental age according to at least one cranial feature information in the morphological developmental feature image of the cranial surface of the user and/or the proportional relationship between different cranial feature information.
Optionally, the developmental age determination model may directly output the developmental age matched with the morphological developmental feature image of the cranial surface according to the cranial feature information. For example: the embodiment of the invention can determine the development age according to the length of a longitudinal axis between the glabellar point and the infranasal point, can also determine the development age according to the width of a transverse axis between the glabellar point and the nasal wing point, and can also determine the development age according to the area of a graph formed between the glabellar point and the pupillary point. For example: the development age was determined to be 17 years when the length of the longitudinal axis between the glabellar point and the infranasal point was 177 pixels. The development age was determined to be 19 years old when the width of the transverse axis between the glabellar point and the alar point was 28 pixels.
