Or the body size measuring units 130 and 230 may be further classified using the attribute of the pattern of the corresponding position matching unit. The body size measuring units 130 and 230 may use any one of the attribute of the object or the pattern object (the pattern attribute of the corresponding position matching unit) or all of them to distinguish the background.

The body size measuring units 130 and 230 may select an attribute selection for distinguishing the pattern object and the background (S410), and may separate the pattern object and the background with the selected attribute (S420).

When the pattern attribute of the corresponding position matching unit is selected, the body size measuring units 130 and 230 can distinguish only the pattern of the corresponding position matching unit. For example, it can be divided into a striped pattern or a dot pattern (background).

At this time, when the pattern object is a striped pattern, the body size measuring units 130 and 230 can separate the pattern object and the background by stretching the body pattern shown in the body region and the arm pattern shown in the arm region.

When the pattern object is a dot pattern, the body size measuring units 130 and 230 can distinguish the pattern object from the background using the body pattern shown in the body region and the arm pattern shown in the arm region, that is, the distribution of the dot pattern .

The body size measuring units 130 and 230 may remove noise from the shape of the separated object from the background by using noise removal filtering, morphology calculation, binary filtering, or the like so that the shape of the object can be clearly displayed.

The body size measuring units 130 and 230 can calculate the attribute value of the pattern object (corresponding position matching unit) (S440). The body size measuring units 130 and 230 can comprehensively calculate the feature value indicating the image coordinate value using the length, thickness or size of the stripe pattern or the dot pattern formed on the torso pattern and the arm pattern, and the distance between the dots .

The body size measuring units 130 and 230 classify the divided pattern objects for corresponding position matching so as to be used for body size measurement (S450). The body size measuring units 130 and 230 classify the pattern objects based on the feature values of the pattern objects. For example, it can be classified by the number of the image coordinates from upper left to lower right according to the feature value size of the pattern object. Or grouping according to the feature value size of the pattern object, and can be classified by the numbering from the upper left to the lower right of the image coordinate.

The body size measuring units 130 and 230 classify the pattern object group after the grouping (S460). For example, according to the feature value size of the pattern object group, it can be classified by the numbering from the upper left to the lower right of the image coordinate. Or by grouping according to the feature value size of the pattern object group and sorting from the upper left of the image coordinate to the lower right.

Fig. 10 is a diagram showing an example in which, when the pattern objects shown in Fig. 9 are stripe patterns, numbering is performed according to the feature values and classification is performed.

Referring to FIG. 10, the body size measuring units 130 and 230 can classify the classified pattern objects into numbers M0_1 to M0_7 according to the feature values of the pattern objects, and classify them.

The body size measuring units 130 and 230 can classify the pattern object for each image according to the photographing angle, such that the front face is represented by 0 degree and expressed by M0_k expression, the left side is classified by 90 degree, and M90_1 through M90_7 are classified.

The body size measuring units 130 and 230 can use each of the sorted pattern objects for position measurement by matching them. For example, M0_1, M20_1, M45_1, M73_1, M90_1, and M120_1 are classified into the same corresponding positions among photographs of various angles, and coordinate values and sizes of each photograph at the corresponding position are converted into coordinate values and sizes The body size can be calculated by integrating.

When the pattern object is a stripe pattern, the body size measuring units 130 and 230 can calculate the body size according to the lengths of the feature values corresponding to the body region and the vertical thicknesses of the feature values.

The body size measuring units 130 and 230 may calculate the feature values corresponding to the arm region or the feature values corresponding to the underbody region in the manner described above.

Fig. 11 is a diagram showing an example in which, when the pattern objects shown in Fig. 9 are dot patterns, the objects are numbered and classified according to the feature values.

11 illustrates dividing the divided pattern objects into several groups using the feature values of the pattern objects when using a plurality of distributed position matching units.

Here, in FIG. 11, the grouping feature values may be set to values having the smallest differences in vertical coordinate values, that is, horizontal patterns may be grouped into one group.

FIG. 11 shows an example in which the numbers are classified by M0_k and M90_k according to the feature values of each pattern object group. It is possible to classify the pattern object for each photograph of various angles, such as frontal view at 0 degree, M0_k expression, left side at 90 degrees, and numbering with M90_k expression.

Each of the classified pattern objects can be used for size measurement by corresponding position matching. For example, M0_1, M20_1, M45_1, M73_1, M90_1, and M120_1 are classified into the same corresponding positions among photographs of various angles, and coordinate values and sizes of each photograph at the corresponding position are converted into coordinate values and sizes The size can be integrated.

The difference between the vertical distance between the patterns measured at the upper portion and the vertical distance between the patterns measured at the lower portion of the frontal subject image shown in Fig. 13 is determined by the photographing angle information, the photographing distance information, the deformation information of the photographing clothes, And inclination information of the measurement surface.

The body size measuring units 130 and 230 compensate the measured distance between the pattern points by using the object images of one or more different shooting angles (S620). For example, as shown in Fig. 13, the slope of the front surface pattern point distance measurement surface with respect to the lateral body axis can be found using the photograph of the side surface with respect to the pattern side point distance of the front side photograph, as shown in Fig.

The body size measuring units 130 and 230 can compensate the distance between the pattern points by using the calculated slope of the distance between the pattern point measuring points. If the body size measuring units 130 and 230 calculate a statistical distance using a plurality of inter-pattern distance, it is possible to remove a large portion of the contribution due to the deformation of the photographing garment at the time of calculating the photographing angle.

The body size measuring units 130 and 230 compare the compensated distance between the patterned points having pixel values and the inter-pattern distance dimension of the photographing clothes to calculate the image-pixel-value corresponding space dimension (S640). For example, it can be calculated in the same manner as " image vertical position y = 1030 pixels, vertical direction 1.25 mm per pixel ".

The body size measuring units 130 and 230 calculate the body plane size between specific points of interest of the body wearing the photographing clothes using the image pixel value corresponding room dimensions (S650).

In FIG. 16, since the upper correction target has nine patterns, it is possible to perform correction with only one correction target, and in the case where there are a plurality of correction targets, the accuracy of correction can be increased, but not limited thereto.

The body size measuring units 130 and 230 may compensate the measured distance between the pattern points by using the subject image of one or more different shooting angles (S720). For example, when the target person's image shown in Fig. 17 is used for the distance between the points of the frontal object image shown in Fig. 16, the inclination of the frontal pattern point-to-point distance measuring surface with respect to the lateral body axis can be known.

The body size measuring units 130 and 230 may calculate the photographing angle based on the geometric-optical relationship using the compensated pattern-to-point distance having the pixel value and the camera parameters or the like (S730).

The body size measuring units 130 and 230 may calculate the actual pixel values by comparing the compensated distance between the patterned points having the pixel values and the distance between the patterns of the photographing clothes (S740).

The body size measuring units 130 and 230 may calculate the body plane size between specific points of interest of the body wearing the photographing clothes using the image pixel value corresponding room dimensions (S750).

Although the embodiment has been described in which the correction target is attached to the photographing garment as described above, it is also possible to attach the correction target to the background near the subject to be photographed without attaching it to clothes, or to place it on the floor. For example, a calibration target can be made in the shape of a hexagon and placed on the floor.
