Drawings
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. The attached drawings are as follows:
FIG. 1 is a flow chart of the main steps of the virtual fitting method of the present invention;
fig. 2 is a detailed step flow diagram of a preferred embodiment of the virtual fitting method of the present invention.
Detailed Description
It should be noted that in the description of the present invention, although the steps of the control method of the present invention are described in a specific order in the present application, the order is not limited, and those skilled in the art can perform the steps in a different order without departing from the basic principle of the present invention.
Based on the problems that the fitting effect of the existing virtual fitting method pointed out in the background technology is not vivid and stereoscopic and the user is difficult to generate relatively real fitting experience, the invention provides a virtual fitting method, aiming at improving the fidelity of a virtual dressing human body model, so that a fitting object can determine and forecast the actual fitting effect through the virtual dressing human body model, and the fitting object can not feel the layering of the virtual fitting effect and the real fitting effect while enjoying the convenience of virtual fitting.
Referring first to fig. 1, fig. 1 is a flow chart of main steps of a virtual fitting method of the present invention. As shown in fig. 1, the virtual fitting method of the present invention includes:
step S1: acquiring image information of a fitting object;
step S2: acquiring image information of a to-be-fitted garment;
step S3: acquiring human body size parameters according to the image information of the fitting object, and determining a region to be shielded by the model;
step S4: acquiring clothes size parameters according to the image information of the clothes to be tested;
step S5: and establishing a dressing human body model with the same posture as the fitting object through the human body size parameter and the clothes size parameter based on the to-be-shielded area of the model.
In steps S1 and S2, the specific type and number of the image information of the fitting object and the fitting object are not limited, for example, the image information of the fitting object or the fitting object may be a video image, and may further include a plurality of pictures with different viewing angles, as long as the obtained image information can clearly show the shape and structure of the fitting object and the fitting object. Of course, the manner of acquiring the image information of the fitting subject and the clothes to be fitted is not limited. For example, the image information of the fitting subject and the fitting object may be acquired by a video acquiring device such as a video recording device or a monitor, or may be acquired by a picture taking device such as a camera.
In steps S3 and S5, the "model to-be-occluded area" is an area that needs to be occluded on the created virtual dressing human body model. When the fitting object is acquired with image information, the specific pose thereof may cause the limb overlapping of the individual body parts of the fitting object. At this time, the body part on the front side can block the body part on the rear side, and the area on the body part on the rear side blocked by the front limb (or clothes on the front limb) is the area to be blocked by the model to be subjected to the blocking treatment. For example, when the wrist and the hand of the fitting subject are placed in front of the trunk, the area of the trunk that is blocked by the wrist and the hand (or the clothing at the wrist and the hand) is the area to be blocked. The model is modeled based on the to-be-shielded area of the model, so that the problem that model overlapping mistakes occur in the position of the to-be-shielded area of a human body model or a clothes model can be avoided, and the problems that before clothes of a back body part appear in the limb overlapping position of a dressing human body model constructed when the dressing model with the same posture as a fitting object is established, and before the clothes of the front body part appear in the virtual floating manner, part of the clothes model on the front body part is lost and displayed and the like are solved.
In the above embodiments, it can be understood by those skilled in the art that although the above main steps are described in conjunction with the sequence of steps S1-S5, this is not a limitation, and those skilled in the art can adjust the sequence of steps to perform the modeling work without departing from the basic principle of the present invention. For example, the operation of acquiring the human body size parameters and the operation of determining the region to be occluded by the model in step S3 may be performed simultaneously in the same step, or may be performed step by step in any order; steps S1 and S2 (or steps S3 and S4) may be performed simultaneously, or may be performed sequentially in any order, such as in the order of S1-S2 or S2-S1 (or S3-S4 or S4-S3). Further, when steps S2 and S4 are located before all steps, the image information acquisition step and the laundry size parameter acquisition step of the to-be-fitted garment may be performed before the fitting subject determines the to-be-fitted garment. For example, when clothes are put in storage, image information of clothes with different sizes in each style is directly acquired, and size parameters of each piece of clothes are acquired and stored according to the acquired image information. When the fitting object determines specific clothes to be fitted, the size parameters of the corresponding clothes to be fitted can be directly called, and the image information and the size parameters of the same clothes to be fitted do not need to be repeatedly obtained for different fitting objects.
By the method, the dressing manikin close to the fitting object in shape and in the same posture as the fitting object can be constructed when the fitting object determines the clothes to be fitted, so that the virtual fitting effect can be close to the real fitting effect of the fitting object to the maximum extent, the fitting object can have fitting experience with extremely high fidelity, and the virtual fitting operation is convenient and real and vivid.
Further, "acquiring the human body size parameter according to the image information of the fitting object" specifically includes:
acquiring the size parameter of the exposed part of the fitting object in the image information of the fitting object;
the dressing position size parameter of the fitting object in the image information of the fitting object is acquired.
In the above-described step, since the fitting object wears the own clothes during the virtual fitting, the collected image information includes the figure of the fitting object wearing the own clothes. At this time, the body of the fitting subject is divided into a portion covered with its own clothes and a portion not covered with its own clothes. The above-mentioned "exposed portion size parameter" is a size parameter of a portion not covered by the own clothes. The "dressing site size parameter" is a size parameter of a portion covered with the clothing of the wearer. For example, when a fitting subject wears a sleeveless one-piece dress, the size parameter of the upper trunk and the legs above the knees covered by the one-piece dress is the dressing site size parameter, and the size parameter of the legs below the knees, arms, hands, shoulders, neck, and the like not covered by the one-piece dress is the exposed site size parameter. The size data of the whole body of the fitting object and the basic modeling data of the body part for constructing the dressing human body model can be obtained only by obtaining the size parameters of the exposed part and the size parameters of the dressing part.
Further, the step of "acquiring the dressing site size parameter of the fitting object in the image information of the fitting object" includes:
acquiring an initial size parameter of a dressing part of a fitting object in image information of the fitting object;
acquiring characteristic information of a fitting object;
and correcting the initial size parameter according to the characteristic information, and taking the corrected initial size parameter as the dressing part size parameter of the fitting object.
In the above-described steps, the "initial size parameter of the dressing site" refers to the size parameter of the own clothes covered on each body part of the fitting subject.
The "characteristic information of the fitting object" means information of basic factors that can affect the body shape of the fitting object or information of decisive factors related to the body shape of the fitting object. As an example, the characteristic information at least includes one or more of sex, race, height, weight, body proportion, and body fat parameters. The sex, race, age, etc. are information of basic factors affecting the body type of the fitting subject, such as short asian, tall europeans, short females, tall males, etc. Height, weight, body proportion, body fat parameters and the like are all information of decisive factors related to the body type of the fitting object.
Since the garment wraps over the body of the fitting subject, the initial dimensional parameters measured at that location are generally close to and greater than the actual dimensional parameters of that location for the same location (the initial dimensional parameters can be considered to be approximately equal to the actual body location dimensional parameters in the case of a garment that is tight against the body). And correcting the basic parameter by using the initial size parameter as the basic parameter and through the characteristic information to enable the basic parameter to approach to a value approximately equal to the actual size parameter.
For example, when a fitting subject wears a long-sleeve sweater, if the wrist circumference is to be collected, the circumference size of the cuff wrapping the wrist needs to be obtained first, and the circumference size is used as the initial size of the wrist circumference; and then acquiring characteristic information of the fitting object, and pre-pushing the body type of the fitting object based on a big data mode through the characteristic information of the fitting object so as to acquire wrist circumference data of the pre-pushed body type, such as the mode of wrist circumference, average number of wrist circumference, proportional distribution of wrist circumference range and the like, thereby determining a correction proportion and the shrinkage degree of the initial size parameter according to the related wrist circumference parameters under the body condition of the fitting object, further realizing the purpose of correcting the initial size parameter and acquiring the size parameter fitting the real wrist circumference of the fitting object.
In addition, in addition to the above-described manner of acquiring the dressing site size parameter, the remaining characteristic information may be added to the characteristic information of the fitting object so as to more accurately correct the initial size. For example, the initial size parameter may be corrected at the same time by acquiring the characteristic information of the fitting subject and the material characteristic and the shape characteristic of the self-body garment. Through the material characteristics and the shape characteristics of the clothes, whether the part of the clothes wrapping the body part is in a close-fitting state or not, whether the part is in a special shape (such as a wide leg shape, a lantern sleeve shape and the like) or not can be reflected, so that the correction accuracy is further improved, and the corrected size parameter is closer to the real size parameter.
In a possible embodiment, the operation of "determining the region to be occluded by the model according to the image information of the fitting object" in step S3 includes:
acquiring the posture characteristic of the fitting object in the image information of the fitting object;
determining the superposition condition of human body overlapped parts of the fitting object according to the posture characteristics;
and determining the region to be shielded of the model according to the superposition condition of the human body overlapped part.
In the above steps, the posture characteristic of the fitting subject is a characteristic capable of representing the body posture shape of the fitting subject when the image information is acquired, such as standing on the vertical hand, inclining on one side, holding with both hands, and the like. By recognizing the posture features of the fitting object in the image information, the posture positions of the body parts of the fitting object can be determined, thereby determining which body parts of the fitting object are overlapped front and back at a forward viewing angle (here, the position of the imaging display device in front of the fitting object relative to the fitting object is defined as the forward viewing angle) so as to determine the distribution position of the model region to be occluded on the human body model. The "overlapping condition of the human body overlapping part" specifically refers to whether the human body overlapping part is covered by the fitting and the overlapping condition of the area which is covered by the fitting, so as to determine the specific size of the blocked area according to the overlapping condition.
Further, the step of determining the region to be occluded of the model according to the overlapping condition of the overlapped parts of the human body specifically comprises the following steps:
judging whether a top layer part in the human body overlapping part is overlapped with a simulated coverage area of the clothes to be tested or not;
and if the top layer part is superposed with the simulated coverage area of the clothes to be tested, determining the shielded area of the simulated coverage area matched with the top layer part as the model to-be-shielded area.
In the above steps, the part of the human body overlapped part which is shielded at the front side is the top layer part, and the shielded part which is positioned at the rear side is the bottom layer part. If the top layer part in the human body overlapping part is superposed with the planned coverage area of the clothes to be tested, the top layer part is covered by the clothes to be tested. At the moment, the area which is covered by the clothes to be tested and wrapped outside the top layer part is the area to be covered by the model. For example, when the wrist is shielded in front of the body, the region of the model, which is shielded to the upper body by the sleeves wrapped on the wrist, is the region to be shielded. When the top layer part and the intended coverage area of the clothes to be tested are matched, matching can be carried out in a one-to-one corresponding mode through the same parts (such as matching the wrist line to the edge of the sleeve opening of the sleeve).
In addition, the step of determining the region to be occluded of the model according to the overlapping condition of the human body overlapping parts specifically further comprises:
and if the top layer part is not coincident with the planned coverage area of the clothes to be tested, determining the shielding area of the top layer part as the model area to be shielded.
In the above steps, if the top layer part in the human body overlapping part is not overlapped with the planned covering area of the fitting, it indicates that the top layer part is not covered by the fitting. At this time, the region shielded by the top layer part is the region to be shielded by the model. For example, when the wrist is shielded in front of the body, the region shielded from the wrist to the upper body is the region to be shielded by the model.
In the actual modeling, the virtual fitting method of the present invention may include any one of the two implementation cases, or both of the two implementation cases. For example, in the case of both of these cases, when the wrist and the hand are shielded in front of the body and the test article is a long-sleeve article, the position of the wrist shielded by the sleeves is the first modeling case (overlapping case), and the hand not shielded by the sleeves is the second modeling case (overlapping case).
Based on the above two technical solutions for determining the region to be occluded by the model, in a specific embodiment, the step S5 includes:
determining a non-occlusion area according to the area to be occluded of the model;
establishing a human body model in the non-occlusion area through the human body size parameters and the posture characteristics of the fitting object;
acquiring point location characteristics of the human body model;
establishing a clothes model on the human body model through clothes size parameters based on point location characteristics;
and completing the clothes model in the area to be shielded of the model through the clothes size parameters corresponding to the top layer part in the overlapped part so as to synthesize the dressing human body model.
In the above step, the "non-occlusion region" is a region where there is no body part overlap. Under the forward view angle, the model parts belonging to the non-shielding area range have no overlapping shielding condition, so that when the human body model is established, most human body models can be directly established through corresponding human body size parameters (such as naked part size parameters and dressing part size parameters) so as to be used as the basis of the dressing human body model. "Point location features" are location features of individual points distributed on the surface of the phantom. Because the clothes and the parts of the human body are corresponding to each other, the parts of the clothes can be positioned to the corresponding positions on the human body model one by one based on each point as a characteristic. When modeling is carried out on the region to be shielded of the model, due to the fact that the clothes to be tested are shielded in front of the human body model, the size parameters of the clothes to be tested, which are located in the region to be shielded of the model, are required to be taken, then the corresponding clothes model part is built in the region to be shielded of the model, and the clothes model part is enabled to be combined with the human body model and the clothes model which are built before.
In another specific embodiment, step S5 includes:
determining a non-occlusion area according to the area to be occluded of the model;
establishing a human body model in the non-occlusion area through the human body size parameters and the posture characteristics of the fitting object;
acquiring point location characteristics of the human body model;
corresponding to each point position characteristic, establishing a clothes model on the human body model through clothes size parameters;
and completing the human body model in the region to be shielded of the model through the human body size parameters corresponding to the top layer part in the overlapped part so as to synthesize the dressing human body model.
In the above steps, when modeling is completed in the non-occlusion region, when modeling is performed in the region to be occluded of the model, since the body part is occluded to the front of the human model, the size parameter of the part needs to be retrieved, and then the corresponding human model part is constructed in the region to be occluded of the model, so that the human model part is joined with the previously established human model and the previously established clothes model, so as to synthesize the complete dressing human model.
Further, after step S1, the virtual fitting method of the present invention further includes:
sharpening the dressing human body model;
and displaying the image information of the dressing human body model through the image display unit.
In the above steps, the sharpening process can make the image contour edge of the dressing human body model clearer, so that the image information of the dressing human body model can be displayed on the image display unit more clearly and vividly. The image display unit is any display device capable of meeting the display requirements of the dressing human body model, such as an LED screen, a dressing mirror with a display function and the like. The image information of the dressing human body model can be an image directly presented by the dressing human body model or a screenshot picture of the dressing human body model.
Referring next to fig. 2, fig. 2 is a flowchart illustrating the detailed steps of the preferred embodiment of the virtual fitting method of the present invention. As shown in fig. 2, the preferred embodiment of the virtual fitting method of the present invention comprises the following specific steps:

step S107: determining a specific human body overlapping part of the fitting object according to the posture characteristics;
step S108: judging whether a top layer part in the human body overlapping part is overlapped with a simulated coverage area of the clothes to be tested or not, and determining the overlapping condition between the top layer part in the human body overlapping part and the simulated coverage area of the clothes to be tested;
if the top layer part in the human body overlapping part is superposed with the simulated coverage area of the clothes to be tested, executing the step S109, otherwise executing the step S1010;
step S109: determining a sheltering area of the quasi-covering area matched with the top layer part as an area to be sheltered by the model;
step S1010: determining the shielding area of the top layer part as the area to be shielded of the model;
while performing steps S101-S1010, the virtual fitting method of the present invention further includes:
step S201: acquiring image information of a to-be-fitted garment;
step S202: acquiring clothes size parameters (or replacing the step S201 and the step S202, at the moment, the virtual fitting method of the invention further comprises the step of calling the clothes size parameters of clothes to be tested in a database);
under the condition that all kinds of size parameters are obtained, the virtual fitting method further comprises the following steps:
step S1011: determining a non-occlusion area according to the area to be occluded of the model
Step S1012: establishing a human body model in a non-shielding area through the size parameter of the exposed part, the size parameter of the dressing part and the posture characteristic;
step S1013: acquiring point location characteristics of the human body model;
step S1014: corresponding to each point position characteristic, establishing a clothes model on the human body model through clothes size parameters;
step S1015: and completing the human body model and/or the clothes model in the area to be shielded by the model according to the human body size parameter and/or the clothes parameter size corresponding to the top layer part in the overlapped part so as to synthesize the dressing human body model.
After the dressing human body model is modeled, the virtual fitting method further comprises the following steps:
sharpening the dressing human body model;
and displaying the image information of the dressing human body model through the image display unit.
In summary, the virtual fitting method of the present invention can create a dressing human body model completely matching the real body shape of the fitting object through the size parameter of the fitting object and the size parameter of the fitting object, so as to present a virtual fitting effect with extremely high fidelity.
