Description

A virtual fitting method

technical field

The invention belongs to the technical field of virtual fitting, in particular to a virtual fitting method.

Background technique

The current virtual fitting system generally adopts the effect of virtual fitting by allowing the user to input human body size parameters and then replacing the real human body with a model corresponding to the body type. This method is firstly inconvenient, secondly, there is no sense of reality, and thirdly, the body size parameters input by the user are not necessarily accurate. Therefore, how to solve the above problems is the direction that those skilled in the art need to study.

technical solutions

In order to solve the above technical problems, the present invention provides a virtual fitting method, which does not require the customer to input the body size, has a strong sense of reality, and has a good fitting effect.

The technical scheme of the present invention is: a virtual fitting method, comprising the following steps:

Step S1: acquiring a human body image;

Step S2: dividing the human body image into a first-side human body image and a second-side human body image with the human body midline as a boundary, and the human body midline refers to the vertical midline of the human body;

Step S3: Obtaining clothing image data, the clothing image data includes the clothing image, and the human-clothing connection parameter points and the human body turning parameter points marked on the clothing image; , the intersection point between the contour line of the clothes and the contour line of the model human body; the human body turning parameter point refers to the turning point near the human body joints on the contour line of the model human body;

Step S4: Based on the human body turning parameter points obtained in step S3, mark the corresponding actual human body turning point A on the first side human body image, and based on the relative positions of the human clothing connection parameter points and the human body turning parameter points, on the first side The corresponding human clothing is marked on the human image to connect to the actual point A;

Step S5: obtaining the corresponding symmetrical actual point A' of the human-clothing connection based on the centerline of the human body based on the actual point A of the human-clothing connection;

Obtain the corresponding symmetrical actual human body turning point A' based on the body midline of the actual human body turning point A;

Step S6: Based on the human body turning parameter points obtained in step S3, mark the corresponding actual human body turning point B on the human body image on the second side, and based on the relative position of the human clothing connection parameter point and the human body turning parameter point, on the second side The corresponding human clothing is marked on the human image to connect with the actual point B;

Step S7: taking the actual point B of the connection between the human body and the clothing and the actual point B of the human body turning as the source point, and taking the corresponding actual point A' of the human clothing connection and the actual point A' of the human body turning as the target point, the second side human body image is deformed;

Step S8: take the human clothing connection parameter point and the human body turning parameter point as the source point, and take the corresponding human clothing connecting actual point A, the human body turning actual point A, the human clothing connecting actual point A', and the human body turning actual point A' as the target point to warp and superimpose the image of the clothing onto the image of the human body.

By adopting the above technical solution, the following technical effects are obtained:

Since the human body is not completely symmetrical, the different posture habits of the human body will exacerbate this asymmetry. At the same time, during the virtual fitting, the person already has clothes on the body, and the clothes to be tried on need to be put on the original clothes of the human body, and the original clothes There will be various asymmetric folds, protrusions, etc. on the edge of the clothes, which will lead to serious asymmetry of the human body contour on both sides of the human body midline. However, the existing virtual fitting system can only fit the clothes according to the human body contour through geometric algorithms. It is impossible to adjust the clothes in place through the elasticity of the clothes material and the stretching of the clothes during the normal fitting, which will lead to the result of irregular clothes after the virtual fitting is fitted to the human body, and people have no interest in fitting. Some existing virtual fitting systems use people to input their own body size and then select a model with a similar body shape to replace the human body, which is costly and has no sense of reality. Although some virtual fitting systems can fit the real human body, they require people to wear it. Tights, poor maneuverability. In the present invention, the human body turning point, the connecting point and the relative position of the human body related to the clothes are used as the clothes parameters. Such parameters are determined for each type of clothes and are not difficult to obtain, and then the human body that clearly exists on the human body is obtained based on the human body turning parameter points. Turn the actual point and then obtain the actual point of the connection between the human body and the clothes, and symmetric the two sides of the human body and the clothes based on the center line of the human body, so that you can not only see the real effect of the clothes on your body during fitting, but will not appear disheveled visual effects , which better solves this problem.

It should be noted that, in the step S5, in addition to obtaining the actual point A' of the connection between the clothes and the actual point A' of the body's midline based on the actual point A of the connection of the human body and the actual point A of the turning point of the human body; Obtain its symmetry point based on the midline of the human body only according to the actual human body turning point A, and then obtain the human-clothing connection parameter point A' based on the relative position of the human body turning parameter point and the human-clothing connection parameter point in the clothing image data, Since the sample clothes are symmetrical, the purpose of obtaining the symmetry point A' of the connection parameter point A of the human body based on the midline of the human body can also be achieved.

It should be noted that the image deformation based on the source point and the target point in the step S7 and the step S8 are commonly used techniques in the art, such as perspective transformation, affine transformation, local image stretching, scaling and rotation, and other source and target-based techniques. Point contour reconstruction scheme, etc.

It should be noted that, for the deformation of the second human body image in the step S7, the actual point B connected with all the clothing and the actual point B of all human turning points can be used as source points, and the corresponding human clothing can be connected with the actual point A' and the human body. The actual turning point A' is used as the target point, and the second side human body image is deformed as a whole; it is also possible to use some human clothing to connect with the actual point B and/or part of the human body to turn the actual point B as the source point, and the corresponding human clothing to connect with the actual point A. 'And the actual human body turning point A' is the target point, and the second side human body image is partially deformed, such as the human body corresponding to the human body turning parameter points in the clothing image data that are connected to the actual point B that does not overlap with the clothing outline. The turning point B is the source point, and the corresponding human clothing connection actual point A' and the human body turning actual point A' are taken as the target point, and only the second side human body image is partially deformed. At this time, the local deformation area is actually exposed when dressing. In the human body area outside the clothes, after the clothing image deformation is superimposed on the human body image in step S8, the corresponding human body image other than the clothing outline segment will be cleared, so the final effect of this local deformation is the same as the overall deformation. Another example is to locally deform only the human body image corresponding to the segment region of the human body contour line where the bilateral human body images are severely asymmetrical, so that symmetry can be achieved to achieve a better balance between the sense of reality and the sense of neatness.

It should be noted that, for the clothing image deformation in the step S8, all clothing connection parameter points and human body turning parameter points can be used as source points, and the corresponding human clothing connection actual points and human body turning actual points can be used as target points. The clothing image is completely and accurately deformed; it is also possible to take some human clothing connection parameter points and/or some human body turning parameter points as source points, and take the corresponding human clothing connection actual points and human body turning actual points as target points to locally deform the clothing image. For example, the human body turning parameter points that overlap with the clothing outline in the clothing image data may not be used as the source point of the deformation of the clothing image. Taking a long-sleeved top as an example, the turning parameter points of the head and neck angle belong to the human body turning points that do not overlap with the clothing outline. Parameter point, since the clothes contour line is an irregular curve, when the neckline contour line is higher than the neckline and neck connection parameter point, if the head and neck angle turning parameter point higher than the neckline and neck connection parameter point is used as part of the source point, it can be guaranteed that The part of the neckline contour line higher than the neckline and neck connection parameter point can be accurately deformed, but even if the head and neck angle turning parameter point is not selected as the source point, the neckline contour line can be deformed, especially when the neckline contour line is not higher than the neckline neck. When the parameter points are connected to each other, accurate deformation can also be achieved. Another example is that only the clothing outline segment area corresponding to the human body outline segment area with severe asymmetry of the bilateral human body images adopts this method to superimpose the clothing image deformation to achieve Strike a balance between realism and neatness.

It should be noted that the deformation of the clothes image in the step S8 may be based on the overall deformation of the source point and the target point, or may be sequentially deformed based on the source point and the target point by region, such as the first side and then the second side based on the midline of the human body, etc. ; It should be noted that, in order to make the dressing effect more beautiful, the position of the target point can be corrected according to the empirical value, and then the clothing image can be deformed.

Preferably, in the above-mentioned virtual fitting method, the step S7 further includes modifying the human body image after the human body image is deformed:

Step 7-1: connecting the source points in step S7 in sequence along the human body contour line before the deformation of the second human body image to obtain a human body contour line segment X1;

Step 7-2: connecting the target points in step S7 along the deformed human body contour line of the second human body image in sequence to obtain a human body contour line segment X2;

Step 7-3: Clear the human body images located inside the human body contour line segment X1 and outside the human body contour line segment X2.

By adopting the above technical solution, the residual human body image other than the human body contour line obtained after the deformation can be removed, so as to ensure a good visual effect.

Preferably, the above-mentioned virtual fitting method further includes step S9, and step S9 is to correct the composite image obtained after the clothes image is superimposed on the human body image:

Step 9-1: Connect the actual point where the human clothing is connected in the target point of step S8 and the actual turning point of the human body that overlaps with the clothing outline along the direction of the clothing outline. When connecting, if the two adjacent points are both If it is the actual point of the human-clothing connection, connect the two points along the outline of the clothing, otherwise, connect the two points along the outline of the human body; obtain the human body area Y1;

Step 9-2: Remove the portion of the human body area Y1 that is beyond the area covered by the clothing image after being deformed and superimposed on the human body image.

Since the contour lines of the clothes and the corresponding contour lines of the human body do not completely match, by adopting the above technical solution, the phenomenon that the clothes are worn inside the human body can be avoided.

Best Mode for Carrying Out the Invention

In this embodiment, the present invention is described based on the virtual fitting process of the long-sleeved top.

As shown in Figure 1, a virtual fitting method includes the following steps:

Step S1: acquiring a human body image;

An example of a human body image is shown in FIG. 2 . In practice, the human body image is a human body image obtained by directly photographing a fitting person by a camera device. Specifically, a photographed image or a photographed video of the fitting personnel is obtained through a camera device, and if it is a photographed video, the steps are performed on each frame of the image in the video. S1-S9, in addition, before performing steps S1-S9 for each frame of the captured image or captured video, the image of the human body part is first cut out through the image recognition technology, which is used as the human body image alone, and the remaining part of the image is used as the background Image, after steps S1-S9 are executed, the synthesized image is embedded on the background image, so as to realize the effect of real mirror fitting.

As shown in FIG. 5 , the second human body image is the right human body image, and the marked actual human body turning point B and the mirrored actual human body turning point A' may overlap and some may not.

After the human body image is deformed, the human body image is corrected:

Step S8: take the human clothing connection parameter point and the human body turning parameter point as the source point, and take the corresponding human clothing connecting actual point A, the human body turning actual point A, the human clothing connecting actual point A', and the human body turning actual point A' as the target Click to deform the clothes image, and superimpose the deformed clothes image on the human body image.

Step S9, modifying the composite image obtained after the clothes image is superimposed on the human body image:

Step 9-1: Connect the actual point where the human clothing is connected in the target point of step S8 and the actual turning point of the human body that overlaps with the clothing outline along the direction of the clothing outline. When connecting, if the two adjacent points are both If it is the actual point of the human-clothing connection, connect the two points along the outline of the clothing, otherwise, connect the two points along the outline of the human body; obtain the human body area Y1 (the area that should be covered by the clothing);

Since the contour lines of the clothes and the corresponding contour lines of the human body do not completely match, by adopting the above technical solution, the phenomenon that the clothes are worn inside the human body can be avoided. The final synthesized image is shown in Figure 6.

In this embodiment, the relative positional relationship between the human-clothing connection parameter point and the human body turning parameter point can be obtained through a variety of common position algorithms, for example, the human-clothing connection parameter point can be between two adjacent human body turning parameter points. The relative position of the human body contour line can be obtained. For example, as shown in Figure 3, the connection point of the outer contour line of the wrist of the cuff of the long-sleeved top can be obtained from the relative position of the body contour line between the elbow point of the outer contour and the wrist point of the outer contour; it can also be obtained by The ordinate of the human-clothing connection parameter point is obtained from the relative position of the ordinate between two adjacent human body turning parameter points, and then its abscissa is obtained based on the horizontal intersection of its ordinate and the adjacent human body outline, or the human-clothing connection is used to obtain its ordinate. The abscissa of the parameter point is obtained from the relative position of the abscissa between two adjacent human body turning parameter points, and then its ordinate is obtained based on the vertical intersection of the abscissa and the adjacent human body contour; it is also possible to connect the parameter points and The relative positions of the ordinate and abscissa between the two adjacent human body turning parameter points can be used to obtain their ordinate and abscissa respectively; the human clothing connection parameter point and the adjacent human body turning parameter point can also be overlapped, as shown in Figure 3 The connection point of the outer contour line of the cuff and wrist of the long-sleeved top may overlap with the point of the outer contour of the wrist. At this time, the position of the connection parameter point of the clothing is the position of the corresponding adjacent human body turning parameter point; those skilled in the art should know that there are also Other point-to-point or point-to-contour based positional algorithms can be used.

Specifically, for a long-sleeved top, in the step S4, the actual point A corresponding to the human body image on the first side of the human body image is obtained based on the relative positions of the human clothing connection parameter point and the human body turning parameter point, or in the step S6 Based on the relative positions of the human-clothing connection parameter point and the human body turning parameter point, the corresponding human-clothing connection actual point B of the second-side human body image is obtained, including the following steps:

The location of the actual point 121. Or, based on the position of the hem waist connection parameter point 103 relative to the acromion turning parameter point 106 and the hip turning parameter point 112 on the same side of the human body midline, obtain the actual acromion turning point 115 of the hem waist connecting actual point 125 relative to the acromion turning parameter point 115 on the same side of the human body midline and the location of the actual point 121 of the hip turning.

It should be noted that since the human body is a whole, in addition to the parts of the human body related to the image data of clothes, the rest of the human body also needs to be symmetrically adjusted based on the midline of the human body to achieve better visual effects. Before the clothing starts, the entire human body is adjusted symmetrically based on the midline of the human body and the turning point of the human body, or after the clothes are fitted, the rest of the human body is symmetrically adjusted based on the midline of the human body and the turning point of the rest of the human body.
