Description

TECHNICAL FIELD [0001] The present invention relates to a method and apparatus for generating a user's three-dimensional body model based on depth information,

Embodiments of the present invention relate to a method and apparatus for generating a three-dimensional body model of a user based on depth information, and more particularly to a method and apparatus for generating a three-dimensional body model by representing a user's body as a three- And more particularly, to a method and apparatus for generating a three-dimensional body model of a user based on depth information for accurate and fast operation.

With the development of technology, a technique of simulating a user's body to be displayed on a display device and displaying a user's avatar in real time has been developed in recent years. These technologies are mainly applied to general retailing such as department store or clothing store. When a consumer buys clothes offline, he or she can try to dress directly because it can not satisfy the expectation by looking. In this case, it can take a long time and inconvenience. In this case, the consumer can improve the convenience of the user by wearing clothes virtually through their avatars without wearing clothes.

However, this conventional technique takes a considerably long time to scan with a camera in order to create a consumer avatar. For example, an avatar can be created only when a consumer's body is photographed. The consumer's body must be photographed at multiple angles, and processing time for generating an avatar after taking a picture is considerably long. If this takes a long time, the need to use these techniques can be reduced because consumers are actually close to the time they wear their clothes. In addition, it is difficult for the prior art to generate an avatar of the exact size and the body of the consumer. For example, when a consumer wears a thick clothes, the camera generates an avatar by judging only the appearance of the user, so that it is impossible to know exactly what the user's body shape is. Therefore, the avatar body shape is completely different from the body shape of the consumer Lt; / RTI > In this case, the avatar does not match the consumer, so there is no need to use this technique.

Therefore, in order to solve the above-mentioned problems, an embodiment of the present invention generates accurate body shape of a user based on data on typical body shape of a general person, It is aimed to create a three-dimensional body model of a fast user.

Hereinafter, a method and apparatus for generating a three-dimensional body model based on depth information according to an embodiment of the present invention will be described in detail with reference to the drawings.

In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. In addition, it should be considered that the components of the drawings attached hereto can be enlarged or reduced for convenience of explanation.

Referring to FIG. 1, an apparatus 100 according to an embodiment of the present invention includes a depth camera 110, a body length measuring unit 120, a database 130, a three-dimensional body model generating unit 140, A body model correction unit 150 and a display unit 160.

The depth camera 110 photographs a specific object using an infrared sensor and acquires depth information in real time for the photographed object. In one embodiment of the present invention, the depth camera 110 is used to capture a user's body and extract depth information of the user's body therefrom. The depth camera 110 extracts depth information from a front or a side view of the user and provides depth information to a body length measuring unit 120, which will be described later. Accordingly, the user must stand in front of the depth camera 110 when photographing the depth camera 110, or take a photograph while standing on the side.

The body length measuring unit 120 measures the length of each part of the user's body. The body length measuring unit 120 includes a linear-length measuring unit 121 and a circumferential length measuring unit 122, and measures a straight-line length and a circumferential length of each body part.

The straight-line-length measuring unit 121 measures the straight-line length of each part of the body through the depth information of the user's frontal granularity, and measures, for example, the leg-length, arm-length, height and width of the body.

The straightness measuring unit 121 first detects the edge of the user's body through an outline extraction algorithm. Referring to FIG. 2A, a body of a user to which an outline extraction algorithm is applied is shown. If the outline extraction algorithm is used, only the silhouette of the user is judged. Referring to FIG. 2B, the straightness measuring unit 121 detects end portions of the user's body such as a hand tip, a foot tip, and the like through a terminal region extraction algorithm based on the determined silhouette of the user. In FIG. 2B, it can be seen that the tip of the hand, the tip of the foot, and the tip of the head are highlighted with a square. Here, the end region extraction algorithm may include a K-Curvature algorithm. Then, based on the determined end of the body, the body's major joints (skeleton joints) or skeletal parts are sensed to distinguish the main body parts. Referring to FIG. 2C, it can be seen that the main joint or skeleton of the body is indicated by a black dot.

Then, the linear length of each part of the body is measured as shown in Fig. 2d. For example, according to the end portion extraction algorithm, the length of the straight line connecting the toe and the head end becomes the user's key (h). Also, when measuring the distance between the black dots on the arm, you can measure the straight length of the lower arm or the total length of the arm. In addition, when measuring the distance between two black points on the boundary between the torso and both arms, the width (w) of the torso can be measured. That is, the distance between the black points or the distance between the distal ends can measure the straight line distance of each part of the body.

The circumferential length measuring unit 122 measures the circumferential length of each part of the body through the depth information of the user's front and side granularity. For example, the circumferential length measuring unit 122 measures the circumferential length of the waist, chest, calf, thigh, .

3A to 3C are illustrations for extracting the waist circumference length from each part of the body. 3A, the circumferential length measuring unit 122 extracts the front circumferential shape of the waist from the depth information of the user's frontal standing figurine. The curved line shown on the left side of FIG. 3A is the frontal circumference of the waist. Then, the circumferential length measuring unit 122 extracts the side circumferential shape of the waist from the depth information of the side grain of the user. The curve shown on the left side of FIG. 3B is in the form of a lateral circumference of the waist. The circumferential length measuring unit 122 estimates that the front circumferential shape of the waist is the rear circumferential shape of the waist and the circumferential shapes of the left and right sides of the waist are all the same. As shown in FIG. 3C, the circumferential length measuring unit 122 may be arranged such that the front surface, the rear surface, the left side surface, and the right side circumferential surface have a full waist circumference shape, and then a position where the joints are arranged between the circumferential shapes is detected. Then, the circumferential length measuring unit 122 inserts the seam at the detected position to complete the entire waist circumference shape. The circumferential length measuring unit 122 can measure the length of the waist circumference from the complete circumferential waist shape completed.

In one embodiment, the circumferential length measuring section 122 may use one or more minutiae points in measuring the frontal circumferential shape and / or the lateral circumferential shape of the waist by the above-described method.

Referring to FIG. 8A, the circumferential length measuring unit 122 may extract a plurality of minutiae (indicated by red dots in FIG. 8A) from a body part to measure the circumferential length. In one embodiment, the feature point may include two points located at both ends of the body quadrant for which the circumference length is to be measured, and a point between two points located at both ends. For example, the characteristic points for measuring the waist circumference may include a starting point and an end point of the waist, and an intermediate point located therebetween. The positions of the minutiae points may be automatically extracted by applying the body end or joint positioning technique described above with reference to FIGS. 2A to 2D, or may be input to the circumference length measuring unit 122 as designated by the user.

Referring to FIG. 8B, the circumferential length measuring unit 122 may extract the three-dimensional point data around the determined minutiae as described above. The three-dimensional point data around the minutiae may include position data of one or a plurality of minia- tions located within a predetermined distance from the minutiae. The predetermined distance may be appropriately determined according to the size of the body part to be measured. In FIG. 8B, exemplary three-dimensional point data extracted for measuring waist, ankle and cuff circumference are shown in red.

Referring to FIG. 8C, in the extracted three-dimensional point data as shown in FIG. 8B, point data in a direction perpendicular to a straight line connecting a plurality of feature points can be extracted again. In FIG. 8C, the plurality of feature points are shown in gray, and the re-extracted point data in the direction perpendicular to the straight line connecting the feature points are shown in red. For example, in the state where the start point, the middle point, and the end point of the waist are extracted by the feature points, three-dimensional point data including the midpoint and arranged in the direction perpendicular to the straight line connecting the start point, the intermediate point, and the end point is extracted . The length of the straight line connecting the re-extracted point data as described above can be measured around the front of the waist. Although the above description has been made with reference to the frontal circumference of the waist, the same procedure can be applied to the measurement of the lateral circumference of the waist or the measurement of the circumference of other different body parts such as the cuff circumference, ankle circumference, chest circumference, pelvic circumference, Can be applied.

According to the embodiment described with reference to Figs. 8A to 8C, more reliable data can be obtained by filtering only point data in the direction perpendicular to the longitudinal direction of the body part to measure the circumference length in the three-dimensional point data .

The database 130 stores a plurality of standard body data. The plurality of standard body data includes information on the length of each part of the body to form a three-dimensional body model classified and selected from standard body data of the people of the user to which the user belongs. For example, standard body data may include linear length and circumferential length of each part of the body, a three-dimensional image of each standard body, and the like.

According to an embodiment of the present invention, a plurality of standard body data may be classified and stored based on at least one of a linear length and a circumference length of each part of the body. Preferably, at least one of the straight length and the circumferential length of each part of the body may be at least one of a height, a waist circumference, and a sex. Preferably nine. When a plurality of standard body data is classified into nine, a three-dimensional image of each standard body is shown in FIG. Referring to FIG. 4, the standard body of a woman is classified into nine types based on the thickness of the key and the body (waist circumference). The type of key is divided into a large key, a middle key and a small key. The thickness of the body is divided into a thick body, a middle body, and a thin body. Particularly, FIG. 4 is classified based on the female body. Therefore, when classifying the body according to the male body, the definition of the length of each part defining the standard body may be changed.

 In addition, the database 130 may store an obesity rate table. The obesity rate is an index that can be used to modify the body image described below. Referring to FIG. 5, the obesity rate table includes information on obesity index and degree of obesity. The WTHR (Waist To Height Ratio) is an obesity index, and the obesity index is measured by the ratio of the original height to the waist circumference. The obesity rate has different obesity indices according to sex, and the higher the obesity index, the higher the obesity rate. The shape of the three-dimensional body model for each degree of obesity may then be stored in database 130. Referring to FIG. 6, a three-dimensional side view of excitation models in the case of low body weight, normal body, and overweight body is shown. The shape of each model is defined such that the waist circumference is significantly different from the thigh circumference to the chest circumference according to the obesity rate.

The three-dimensional body model generation unit 140 generates a three-dimensional body model based on the user profile condition inputted by the user, the user's key and the waist circumference length, Match the data and generate a three-dimensional body model through the matching result. For example, when the user's body is judged to be close to the " large key & middle body " among the nine standard bodies, the three-dimensional body model of the user is " Large key & middle < / RTI > torso ". Specifically, each of the standard body data is weighted according to the user's key and waist circumference, and the standard body data reflecting the weight is linearly summed. At this time, the combined result can be used to create a user's three-dimensional body model similar to any of the nine standard bodies. The generated three-dimensional body model is a model representing the entire body of the user, and the user's face can be selectively reflected.

The three-dimensional body model modifier 150 modifies the generated three-dimensional body model in detail to generate a secondary three-dimensional body model. Since the generated three-dimensional body model is generated based on only the standard body data, key, and waist circumference, the shape and the approximate shape of the actual user are similar, but the shapes and lengths are not the same. Therefore, in order to correct such a portion, the three-dimensional body model correcting unit 150 calculates the position of each joint, the lower arm length, the upper arm length, the calf length, the thigh length, The three-dimensional body model is modified using detailed body part information such as the chest circumference, the width of the body, and the like.

In addition, the three-dimensional body model correction unit 142 can use the obesity rate as a measure of the correction of the three-dimensional body model. Specifically, the three-dimensional body model correction unit 142 can calculate the obesity index using the user's key and waist circumference. The three-dimensional body model correction unit 142 determines the degree of obesity of the user with reference to the obesity rate table stored in the database 130 according to the calculated obesity index. Then, the three-dimensional body model correction unit 142 reflects the modification of the user's three-dimensional body model with reference to the shape of the three-dimensional body model according to the determined degree of obesity. For example, if the degree of obesity is " overweight ", the user's three-dimensional body model may be modified so that waist circumference, chest circumference, thigh circumference become thicker. On the other hand, in the measurement of obesity rate, if the user's weight is also an additional input variable, more accurate obesity rate can be measured, so that a more accurate 3-dimensional body model can be corrected.

The display unit 160 displays the modified three-dimensional body model of the user and provides it to the user. The display unit 160 may include a display device, a screen, or the like capable of displaying an image.

Hereinafter, a method of generating a three-dimensional body model based on depth information according to an embodiment of the present invention will be described in detail with reference to FIG.

First, a user shoots a body through an image display device according to an embodiment of the present invention (S101). The body of the user is photographed through the depth camera 110 (see FIG. 1) of the image display apparatus, and the user poses such that at least one of the front or side granularity of the user is photographed by the depth camera 110. When the frontal standing image is photographed, more accurate depth information can be extracted if the user shoots with both arms, such as a pose of the model shown in FIG. 2A. On the other hand, in order to measure the waist circumference length, it is necessary to acquire depth information about the front and side surface granularity, and therefore, it is preferable that both frontal and lateral granularity of the user are photographed for more accurate body measurement.

Then, the straight-line length measuring unit 121 (see Fig. 1) measures the straight length of each part of the body (S102). As described above, the straight-line length measuring unit 121 obtains information on the edges of the user's body, obtains information on the positions of the body ends thereof, and obtains information on the joints and important parts. The straight-line-length measuring unit 121 may measure the positions of the finally obtained joints or important parts with black points, and measure straight-line distances between the body parts including the keys through the distance between the black points.

Then, the circumferential length measuring unit 122 (see Fig. 1) measures the circumferential length of each part of the body (S103). As described above, the circumferential length measuring unit 122 grasps the front circumferential shape and the side circumferential shape of each region through the depth information on the front and side grain phases of the body. Then, after the position of the joint for connecting the front and side circumferential shapes is detected, the circumferential length of each region including the waist circumference can be measured by completing the entire circumferential shape.

In one embodiment, the step of measuring the circumference length includes the steps of extracting a plurality of feature points from a region to measure the circumference of the body, extracting three-dimensional point data around the feature points, Extracting point data perpendicular to a straight line connecting the plurality of feature points, and measuring the circumferential length of the body using point data perpendicular to the straight line connecting the plurality of feature points. Since these steps have been described above with reference to Figs. 8A to 8C with respect to the circumferential length measuring unit, detailed description will be omitted.

Next, the three-dimensional body model generation unit 140 (see FIG. 1) generates a three-dimensional body model of the user using a plurality of standard body data based on the measured key and waist circumference length (S104). Specifically, the measured key and the waist circumference are used to determine whether the user's body is close to which of a plurality of standard body data. For example, when the first standard body data, the second standard body data, ..., the ninth standard body data are defined, the user's key and waist circumference are close to the second standard body data, It can be judged to be the most distant from the data. At this time, the highest weight is applied to the second standard body, the lowest weight is applied to the ninth standard body data, and the appropriate weight is applied to the remaining standard body. Then, the three-dimensional body model of the user can be generated by linearly adding each weighted standard body data.

Illustratively, equations (1) and (2) below mathematically illustrate a method for generating a three-dimensional body model.

[Equation 1]

&Quot; (2) "

In Equation (1), B is a value for the generated three-dimensional body model. wi (α, β) is a weight, and α and β are variables related to the key and waist circumference. That is, the weight is determined according to the key and the waist circumference. As can be seen from Equation (2), the sum of all the weights should be 1. pi denotes standard body data. i is an index of standard body data, n is the number of standard body types, n = 9 when standard body is defined as 9, and i is defined as 0 to 8.

Then, the three-dimensional body model modifier 150 (see FIG. 1) modifies the three-dimensional body model using data on the detailed parts of the body such as arm length, leg length, and the like (S105). Since the three-dimensional body model is roughly formed, detailed body parts need to be adjusted. Therefore, the three-dimensional body model is modified by reflecting detailed items such as arm length, leg length, chest circumference, and joint position. At this time, the obesity rate may be measured and further reflected in the correction of the three-dimensional body model.

Finally, the modified three-dimensional body model is displayed through the display unit 160 (see FIG. 1) (S106). The user can visually confirm his / her three-dimensional body model through the display unit 160. At this time, the user's body may be displayed in three dimensions, but the user's background image may be displayed in a two-dimensional manner. That is, when a user is photographed with a camera and the avatar of the user is displayed on the display unit, the avatar of the user is displayed in a three-dimensional manner, but the background displayed behind the avatar of the user can be processed and displayed in two dimensions.

As described above, according to an embodiment of the present invention, a plurality of pieces of standard body data are specified, and a three-dimensional body model of a user is generated through a plurality of pieces of standard body data using only a user's key and waist circumference length, You can create fast and accurate three-dimensional body models. Since the stereoscopic image reproduction technique of a body in a general store as in the retailer is a key to how accurately and rapidly a three-dimensional body model is generated, an embodiment of the present invention is not limited to the conventional art in the technical field of the present invention It will have a great effect.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

Therefore, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concept of the present invention defined in the following claims are also within the scope of the present invention.
