[0038] Referring to Figures 1 to 4 , a drapeability testing device 100 (hereinafter, can be referred to as "device 100") can be used to scan an outer shape of a fabric (for example, a fabric FB of Figures 5 to 7 ) to collect data for inferring a property of the fabric. For example, the property of the fabric can include at least one of a stretch-weft stiffness, a stretch-warp stiffness, a shear stiffness, a bending-weft stiffness, a bending-warp stiffness, or a bending bias stiffness of the fabric, or a combination thereof. Among them, the weft refers to a horizontal yarn of the fabric, and can also be referred to as a weft thread. In addition, the warp refers to a vertical yarn of the fabric, and can also be referred to as a warp thread.

[0039] The device 100 can measure and / or evaluate a change in appearance (for example, deformation) of the fabric FB due to its own weight under a certain condition. The device 100 can be placed on a substantially flat surface (for example, the ground) in a gravity-acting environment.

[0040] The device 100 can include a stationary structure 110. The stationary structure 110 can be substantially stationary with respect to other components (e.g., the first moving structure 130 or the second moving structure 140).

[0041] The stationary structure 110 can include a base 111. The base 111 can support other components (e.g., the first leg 112, the second leg 113, or the light source L). The base 111 can include an opening in which a fixing member (e.g., a screw) for fixing the other components is fixed. The base 111 can provide a support surface (e.g., a +Z normal direction surface) on which the other components can be placed. The base 111 can include an opening in which a fixing member (e.g., a screw) for fixing the other components is fixed. The base 111 can be plate-shaped, but is not limited thereto, and can be various shapes. The base 111 can include a metal material. For example, the base 111 can include aluminum. The other components can be placed on the base 111.

[0042] The stationary structure 110 can include the first leg 112. The first leg 112 can be disposed on the base 111. The first leg 112 can be disposed on a first portion (e.g., a -Y direction edge portion) of the base 111. The first leg 112 can extend from the base 111 in a normal direction (e.g., a +Z direction) of the base 111. The first leg 112 can be supported by the base 111. The first leg 112 can include a metal material. For example, the first leg 112 can include aluminum.

[0043] The stationary structure 110 can include the second leg 113. The second leg 113 can be disposed on the base 111. The second leg 113 can be disposed on the base 111 in a position opposite the first leg 112 with the first moving structure 130 as a reference. The second leg 113 can be disposed on a second portion (e.g., a +Y direction edge portion) of the base 111. The second leg 113 can extend from the base 111 in a normal direction (e.g., a +Z direction) of the base 111. The second leg 113 can be supported by the base 111. The second leg 113 can include a metal material. For example, the second leg 113 can include aluminum.

[0044] In an embodiment not shown, the stationary structure 110 can include only a single leg (e.g., the first leg 112). In an embodiment not shown, the stationary structure 110 can include more than three legs (e.g., the first leg 112, the second leg 113, a third leg, etc.) disposed on different portions of the base 111.

[0045] The fixing body 110 may include an extension 114. The extension 114 may extend between the first leg 112 and the second leg 113. The extension 114 may be connected to a first end portion (e.g., a +Z direction end portion) of the first leg 112. The extension 114 may be connected to a first end portion (e.g., a +Z direction end portion) of the second leg 113. The extension 114 may be disposed on the base 111. Other components (e.g., a first moving body 130 or a second moving body 140) may be disposed between the base 111 and the extension 114.

[0046] Extension 114 may include a three-dimensional structure (e.g., a rectangular plate) having a polygonal cross-sectional shape. Extension 114 may be substantially flat. Extension 114 may include a metallic material. For example, extension 114 may include aluminum. Extension 114 may substantially remain stationary in its own position.

[0047] The device 100 may include a first movable body 130. The first movable body 130 may be configured to move relative to a fixed body 110. At least a portion of the first movable body 130 may be supported by a second movable body 140. The first movable body 130 may move (e.g., rise) in a direction substantially opposite to the direction of gravity (e.g., the +Z direction). When the first movable body 130 moves in a direction substantially opposite to the direction of gravity (e.g., the +Z direction), the first movable body 130 may be fixed to the fixed body 110. The first movable body 130 may be configured to move to a predetermined position (e.g., Figure 6 When the second height D2 is reached, it is fixed to the extension 114. For example, the first movable body 130 may include a magnet. For example, the first movable body 130 may be configured to move from the base 111 to a substantially predetermined height (e.g., at a second height D2). Figure 6 When the second height D2) is the same height, it can be fixed to the extension 114 by magnet.

[0048] The first movable body 130 can be a fabric (e.g., Figures 5 to 7 The first movable body 130 provides a supporting surface for the fabric (FB). For example, the first movable body 130 may be configured to support a region of the fabric (e.g., a central region). For example, the supporting surface of the first movable body 130 (e.g., the surface at the upper end) may include a three-dimensional structure (e.g., a circular plate) having a substantially circular or elliptical cross-section. In embodiments not shown, the first movable body 130 may include a three-dimensional structure having a polygonal cross-sectional shape (e.g., a rectangular plate). In embodiments not shown, the first movable body 130 may include a substantially spherical or hemispherical three-dimensional structure. The supporting surface of the first movable body 130 may be substantially flat. The first movable body 130 may include a metallic material. For example, the first movable body 130 may include aluminum.

[0049] The device 100 may include a second movable body 140. The second movable body 140 may be configured to move relative to the fixed body 110. The second movable body 140 may be configured to move (e.g., rise) in a direction substantially opposite to the direction of gravity (e.g., the +Z direction). The second movable body 140 may be configured to move (e.g., fall) in a direction substantially in the direction of gravity (e.g., the -Z direction). When the first movable body 130 is fixed to the fixed body 110 or the extension 114, the second movable body 140 may move in a direction substantially in the direction of gravity. The movement of the second movable body 140 relative to the fixed body 110 can cause natural and / or constant shape changes in the fabric FB.

[0050] The second movable body 140 may include a first plate 141. The first plate 141 may be configured to support a fabric (e.g., a support fabric) similar to that supported by the first movable body 130. Figures 5 to 7 The fabric FB has different regions (e.g., the central region) from other regions (e.g., the surrounding region). The first plate 141 can move in a direction substantially opposite to the direction of gravity (e.g., the +Z direction). When the first plate 141 moves in a direction substantially opposite to the direction of gravity (e.g., the +Z direction), the first moving body 130 can simultaneously move in a direction substantially opposite to the direction of gravity. During the movement of the first plate 141 substantially in a direction opposite to gravity, the height of one side of the first moving body 130 (e.g., the surface in the +Z normal direction) and the height of one side of the first plate 141 (e.g., the surface in the +Z normal direction) can be substantially the same.

[0051] The first plate 141 can be configured to move (e.g., descend) along a substantially gravitational direction (e.g., the -Z direction). When the first plate 141 moves along a substantially gravitational direction, the first moving body 130 can be fixed relative to the extension 114. When the first plate 141 moves (e.g., descends) along a substantially gravitational direction (e.g., the -Z direction), the support force of the first plate 141 on the fabric is reduced or removed, and the area supported by the first plate 141 on the fabric (e.g., the surrounding area) may droop in the gravitational direction.

[0052] The first plate 141 may extend around its central axis (e.g., the Z-axis). For example, the first plate 141 may include an annular shape having an inner edge and an outer edge. The central axis of the first plate 141 may substantially coincide with the central axis of the first moving body 130.

[0053] The first plate 141 can be disposed outside the first moving body 130. Before the first plate 141 moves (e.g., rises) in a direction substantially opposite to the direction of gravity (e.g., +Z direction), the position (e.g., height from the base 111) of the first plate 141 can be substantially the same as the position (e.g., height from the base 111) of the first moving body 130.

[0054] The second moving body 140 can include a first hole 142. At least a portion of the first moving body 130 can be accommodated in the first hole 142. The first hole 142 can be substantially circular or elliptical. The shape of the first hole 142 is not limited to a circular or elliptical shape, but can include a shape complementary to the shape of the first moving body 130. The first hole 142 can be disposed in a central region of the first plate 141. The first hole 142 can be defined by an inner side edge of the first plate 141. The first hole 142 can pass through a first side (e.g., +Z direction side) and a second side (e.g., -Z direction side) opposite to the first side of the first plate 141. A central axis (e.g., Z axis) of the first hole 142 can be substantially identical to a central axis (e.g., Z axis) of the first moving body 130.

[0055] The second moving body 140 can include a plurality of second holes 143. The plurality of second holes 143 can pass through the first side (e.g., +Z direction side) and the second side (e.g., -Z direction side) opposite to the first side of the first plate 141. Air can flow through the plurality of second holes 143. For example, when the first plate 141 descends, air located at the second side of the first plate 141 can flow to the first side of the first plate 141 through the plurality of second holes 143, which can reduce air resistance of the first plate 141. Accordingly, when the fabric is hung down along the direction of gravity, the fabric can exhibit a desired shape change (e.g., a natural and consistent shape change).

[0056] The plurality of second holes 143 can include a substantially circular or elliptical cross-sectional shape. The plurality of second holes 143 is not limited to a circular or elliptical shape, but can include any shape suitable for air to pass through. For example, the plurality of second holes 143 can include a polygonal shape such as a rectangular or octagonal shape.

[0057] The plurality of second holes 143 can be arranged around a central axis of the first plate 141 and in a direction around the first plate 141. The second moving body 140 can include a plurality (e.g., 7) of columns of second holes 143 having different distances from the central axis of the first plate 141 between an inner side edge and an outer side edge of the first plate 141. Some columns of second holes 143 can be disposed at a position close (e.g., a first distance) to the inner side edge of the first plate 141. Some columns of second holes 143 can be spaced apart from the outer side edge of the first plate 141 by a distance (e.g., a second distance greater than the first distance). The size of each of the plurality of second holes 143 can be smaller than the size of the first hole 142.

[0058] The second movable body 140 may include a plurality of second plates 144. For example, one of the plurality of second plates 144 may be disposed in a first side edge region of the first plate 141, and another second plate may be disposed in a second region opposite to the first side edge region of the first plate 141. In embodiments not shown, the second movable body 140 may include three or more second plates 144 disposed in different side edge regions of the first plate 141. In embodiments not shown, the second movable body 140 may include a single second plate 144. The end region of each of the plurality of second plates 144 may be connected to a side of the first plate 141. The plurality of second plates 144 may include a metallic material. For example, the plurality of second plates 144 may include aluminum. The plurality of second plates 144 may each be configured to face a corresponding leg (e.g., a first leg 112, a second leg 113, or a third leg (not shown)). For example, a second plate 144 may be disposed inside the first leg 112 (e.g., in the +Y direction) and facing the first leg 112, and another second plate 144 may be disposed inside the second leg 113 (e.g., in the -Y direction) and facing the second leg 113. Multiple second plates 144 may have surfaces with normal directions (e.g., in the X and / or Y directions) different from the normal direction (e.g., in the Z direction) of the surface of the first plate 141. Multiple second plates 144 may be parallel to the first leg 112 and / or the second leg 113, respectively.

[0059] The second movable body 140 may include a protrusion 145. The protrusion 145 may be configured to support the first movable body 130. A user may place the first movable body 130 on the protrusion 145 before performing a sag test. The protrusion 145 may be located in the central region of the first plate 141. The protrusion 145 may protrude from the inner edge of the first plate 141 toward the central axis (e.g., the Z-axis) of the first plate 141. The protrusion 145 may be formed in a stepped shape along the inner edge of the first plate 141. The protrusion 145 may be formed along the edge of the lower end region (e.g., the -Z-axis direction end region) of the inner edge of the first plate 141. The protrusion 145 may be stepped, but is not limited to this, and the protrusion 145 may have any shape protruding toward the inner edge of the first plate 141.

[0060] A thickness that is a sum of a thickness (e.g., a thickness in a Z-axis direction) of the protrusion 145 and a thickness (e.g., a thickness in a Z-axis direction) of the first moving body 130 can be substantially the same as a thickness (e.g., a thickness in a Z-axis direction) of the first plate 141. When the protrusion 145 supports the first plate 141, a height of a first face (e.g., a +Z normal direction surface) of the first moving body 130 and a height of a first face (e.g., a +Z normal direction surface) of the first plate 141 can be substantially the same. The protrusion 145 can include a metal material. For example, the protrusion 145 can include aluminum.

[0061] The protrusion 145 can be disposed at an arbitrary position of an inner side of the first plate 141 for supporting the first moving body 130. For example, in an embodiment not illustrated, the protrusion 145 can be disposed at a lower side (e.g., a -Z normal direction side) of the first plate 141 and protrude toward a central axis of the first plate 141. The protrusion 145 can support the first moving body 130 at the lower side of the first plate 141. When the protrusion 145 is disposed at the lower side of the first plate 141, a thickness (e.g., a thickness in a Z-axis direction) of the first moving body 130 can be substantially the same as a thickness (e.g., a thickness in a Z-axis direction) of the first plate.

[0062] The fixed body 110, the first moving body 130, and the second moving body 140 can have a color (e.g., black) having a saturation lower than a saturation of a fabric (e.g., a fabric FB) of Figures 5 to 7 This can help to improve recognition of the fixed body 110, the first moving body 130, and the second moving body 140 by an optical device (e.g., the camera 190). For example, the fixed body 110, the first moving body 130, and the second moving body 140 can be anodized.

[0063] The device 100 can include a fixing part 150. The fixing part 150 can fix a fabric (e.g., a fabric FB) of Figures 5 to 7 to the extension part 114. The fixing part 150 can fix the first moving body 130 to the extension part 114. The fixing part 150 can include various structures (e.g., an electromagnet, a fixing anchor, etc.) for fixing the first moving body 130 and / or the fabric to the extension part 114. For example, the fixing part 150 can directly magnetically fix the first moving body 130 to the extension part 114. For example, the fixing part 150 can fix the first moving body 130 to the extension part 114 through magnetic coupling between other components (e.g., a first fixing member 151 and a second fixing member 152). The fixing part 150 can reduce or prevent an undesired morphological change of the fabric due to air flow around the fabric during a process in which the first plate 141 descends. The fixing part 150 can be configured to fix the first moving body 130 to the extension part 114 when the first moving body 130 moves to a predetermined height (e.g., a height corresponding to a height of the first plate 141) from the base 111. Figure 6When the first moving body 130 moves to a position at a second height D2 that is substantially the same height as the first height D1, the first moving body 130 is fixed to the fixed body 110 or the extension 114. When the first moving body 130 is fixed to the fixed body 110 or the extension 114, the second moving body 140 can move with respect to the first moving body 130 along a substantially gravity direction (e.g., -Z axis direction).

[0064] The fixing part 150 can include a first fixing member 151 disposed at the extension 114. The first fixing member 151 can include a magnet. The first fixing member 151 can be disposed at a lower surface (e.g., -Z direction surface) of the extension 114. The first fixing member 151 can be disposed at a center axis (e.g., Z axis) of the first plate 141. Although the first fixing member 151 is disposed at the lower surface of the extension 114 in the drawing, it is not limited thereto, and can be disposed at any position capable of fixing the first moving body 130 and / or the fabric.

[0065] The fixing part 150 can include a second fixing member 152 disposed at the first moving body 130. The second fixing member 152 can include a magnet. The second fixing member 152 can be disposed at a lower surface (e.g., -Z direction surface) of the first moving body 130. The second fixing member 152 can include a magnet.

[0066] When the first moving body 130 moves to a position at a second height D2 that is substantially the same height as the first height D1, Figure 6 The first fixing member 151 and the second fixing member 152 can be magnetically coupled when the first moving body 130 moves to a position at a second height D2 that is substantially the same height as the first height D1. Between the first fixing member 151 and the second fixing member 152, the first moving body 130 and / or the fabric FB can be fixed.

[0067] The fixed body 110 can include a plurality of linear guide parts 120. The plurality of linear guide parts 120 can be configured to guide linear movement of the second moving body 140. For example, the plurality of linear guide parts 120 can guide the second moving body 140 to descend along a substantially gravity direction. For example, the plurality of linear guide parts 120 can guide the second moving body 140 to move in a direction substantially opposite to the gravity direction.

[0068] The plurality of linear guide parts 120 can respectively include a rail 121 and a slider 122 sliding along the rail 121. One rail 121 can be disposed at the first leg part 112, and the other rail 121 can be disposed at the second leg part 113. The slider 122 can be disposed at a corresponding one of the second plates 144.

[0069] The rail 121 can extend along the inner side of the first leg 112 or the second leg 113 toward the extension direction (e.g., the Z direction) of the first leg 112 or the second leg 113. The slider 122 can be disposed at the lower region of the outer side of the second plate 144. In an embodiment not shown, the rail 121 can be disposed at the second plate 144, and the slider 122 can be disposed at the first leg 112 or the second leg 113.

[0070] The device 100 can include an actuator 160 for moving (e.g., lifting up) the second mobile body 140 in a direction substantially opposite to the direction of gravity (e.g., the +Z axis direction). The actuator 160 can be disposed at the first leg 112 or the second leg 113. The actuator 160 can be configured to slide the slider 122 with respect to the rail 121 in a direction substantially opposite to the direction of gravity. The actuator 160 can be configured to freely fall in a direction substantially in the direction of gravity (e.g., the -Z axis direction) when the first plate 141 moves by substantially the same height as a predetermined height (e.g., the second height D2). Figure 6 The actuator 160 can be configured to not substantially interfere with the descent of the second mobile body 140 when the second mobile body 140 descends. For example, during the process in which the actuator 160 lifts up the second mobile body 140, the actuator 160 is coupled with the second plate 144 or the slider 122, and when the first plate 141 moves to the predetermined height (e.g., the second height D2), the coupling is released. Figure 6 The actuator 160 can be configured to not substantially interfere with the descent of the second mobile body 140 when the second mobile body 140 descends. For example, during the process in which the actuator 160 lifts up the second mobile body 140, the actuator 160 is coupled with the second plate 144 or the slider 122, and when the first plate 141 moves to the predetermined height (e.g., the second height D2), the coupling is released.

[0071] The device 100 can include a coupler 170. The coupler 170 can be configured to couple the second mobile body 140 to the fixed body 110. The coupler 170 can be configured to control the descent of the second mobile body 140. For example, in the coupled state, the second mobile body 140 can be kept stationary with respect to the fixed body 110, and in the decoupled state, the second mobile body 140 can be moved with respect to the fixed body 110. For example, the coupler 170 can be configured to couple the second mobile body 140 to the fixed body 110 when the first plate 141 moves by substantially the same height as a predetermined height (e.g., the second height D2), and when the coupler 170 causes the fixed body 110 and the second mobile body 140 to be decoupled, the second mobile body 140 can descend. Figure 6 The actuator 160 can be configured to not substantially interfere with the descent of the second mobile body 140 when the second mobile body 140 descends. For example, during the process in which the actuator 160 lifts up the second mobile body 140, the actuator 160 is coupled with the second plate 144 or the slider 122, and when the first plate 141 moves to the predetermined height (e.g., the second height D2), the coupling is released.

[0072] The coupler 170 can include a first electromagnetic element 171 and a second electromagnetic element 172 that are electromagnetically coupled to each other. For example, the first electromagnetic element 171 and the second electromagnetic element 172 can each include an electromagnet. The first electromagnetic element 171 and the second electromagnetic element 172 can maintain a coupled state when a current flows through the first electromagnetic element 171 and the second electromagnetic element 172, and the first electromagnetic element 171 and the second electromagnetic element 172 can be separated when the current flowing through at least one of the first electromagnetic element 171 and the second electromagnetic element 172 is reduced or disappears. The first electromagnetic element 171 can be disposed at an upper portion of one leg (e.g., the first leg 112 or the second leg 113), and the second electromagnetic element 172 can be disposed at a lower portion of one second plate 144 corresponding to the leg.

[0073] In an embodiment, the coupler 170 can include an electromagnetic element and a magnetic element. For example, the electromagnetic element can include an electromagnet, and the magnetic element can include a permanent magnet. The electromagnetic element and the magnetic element can maintain a coupled state when a current flows through the electromagnetic element, and the electromagnetic element and the magnetic element can be separated when the current flowing through the electromagnetic element is reduced or disappears. For example, the electromagnetic element can be implemented as one of 171 and 172 shown in FIG. 17, and the magnetic element can be implemented as the other of 171 and 172 shown in FIG. 17. Figure 1 、 Figures 4 to 7 Figure 1 、 Figures 4 to 7

[0074] The device 100 can include a laser 180. The laser 180 can be configured to irradiate a laser to a central axis (e.g., a Z axis) of the first plate 141 and / or a central axis (e.g., a Z axis) of the first moving body 130 when the first moving body 130 and / or the second moving body 140 is positioned at a position before rising (e.g., a position at the first height D1 in FIG. 16). Figure 5 A user can place a center of a fabric (e.g., the fabric FB) at a position substantially identical to a center of the first moving body 130 by a position where the laser is irradiated. Figures 5 to 7

[0075] The laser 180 can be positioned on the extension 114. The extension 114 can include a hole (not shown) through which the laser passes, to allow the laser 180 to irradiate the laser to the central axis of the first moving body 130. The fixing portion 150 can include a hole (not shown) through which the laser passes, to allow the laser 180 to irradiate the laser to the central axis of the first moving body 130.

[0076] ​​​In an embodiment not shown, the laser 180 can be disposed at an arbitrary position capable of irradiating a laser to a substantially center of the first mobile body 130. At this time, the extension 114 or the fixing portion 150 can not include a hole through which the laser passes. For example, the laser 180 is located on a center axis of the extension 114 in the drawing, but the laser 180 can be located at another position on the extension 114. The direction of the laser 180 can be set to irradiate a laser to a center axis of the first mobile body 130 from an arbitrary position on the extension 114.

[0077] In an embodiment not shown, the laser 180 can be located on another component (for example, a housing C of the device 100) other than the extension 114. The direction of the laser 180 located on the other component can be set to irradiate a laser to a center axis of the first mobile body 130. Figure 8

[0078] In an embodiment not shown, the device 100 can not include the laser 180. A user can place a fabric (for example, a fabric FB of the device 100) on the first plate 141 at a desired position even if the device 100 does not include the laser 180. For example, the fabric can include a mark (for example, a "+" mark) passing through a substantially center of the fabric, and the user can place the fabric using a portion of the mark extending to intersect an edge portion of the fabric so that the mark is aligned with a substantially center of the first plate 141. Figures 5 to 7

[0079] The device 100 can include a camera 190. The camera 190 can be disposed on the base 111. The camera 190 can be disposed between the base 111 and the first mobile body 130. The camera 190 can be substantially disposed on a center axis (for example, a Z-axis) of the first mobile body 130. In an embodiment not shown, the camera 190 can be disposed at an arbitrary position capable of acquiring an image of a fabric. The camera 190 can be configured to acquire an image of a fabric by photographing a lower side (for example, a -Z direction side) of the first mobile body on the base 111. When the camera 190 is located below the first mobile body, the device 100 is more compact than when the camera 190 is located above the first mobile body. The camera 190 can have a viewing angle capable of acquiring an image of a fabric at a relatively close distance (for example, a distance of a second height D2 in the drawing). Figure 6 The viewing angle of the camera 190 can have an appropriate value according to a distance (for example, a second height D2 in the drawing) between the raised extension 114 and the camera 190. Figure 6

[0080] Referring to Figure 9 , the device 100 can include a texture scanner 192. The texture scanner 192 can scan a fabric (for example, a fabric FB of the device 100). Figures 5 to 7 ​​​The texture scanner 192 can acquire an image of the fabric (FB) to scan the texture. For example, when the first moving body 130 is located at a first height D1 from the base 111, the first plate 141 is also located at a first height D1 from the base 111, and the fabric FB is located on the first moving body and the first plate, the texture scanner 192 can scan the texture of the fabric. The texture scanner 192 can be located on the extension 114. The texture scanner 192 can be located on the extension 114. The texture scanner 192 can be located on the substantially central axis of the extension 114. Although the laser 180 is not shown in the figures, both the laser 180 and the texture scanner 192 can be located on the extension 114. The device 100 may include a light source L. The light source L may be disposed on the base 111. The light source L may be provided on the base 111, and a camera 190 may be provided on the light source L. The light source L may be configured to illuminate the fabric (e.g., ... Figures 5 to 7 The light source L illuminates the fabric (FB). The light source L can improve the camera 190's ability to recognize the fabric. The light source L may include an LED. During the drape test, the light source L can position the camera 190 on the housing (e.g., ...). Figure 8 An image of the fabric without shadows was obtained from the outer shell (C).

[0081] Unlike a system where a light source L is mounted on a base 111 and a camera 190 is mounted on the light source L, the light source L on the base 111 can be located in a different area than the camera 190. For example, if the camera 190 is located in a region on the base 111 (e.g., the central region of the base 111), the light source L can be located in a different region (e.g., the surrounding area of ​​the base 111) where the camera 190 is not located. The light source L located in the surrounding area can surround at least a portion of the camera 190.

[0082] The light source L can be configured to direct light onto the fabric (e.g., Figures 5 to 7 The light source L illuminates the fabric (FB). The light source L can enhance the camera 190's ability to recognize the fabric. The light source L may include an LED. During the drape test, the light source L can position the camera 190 within the housing (e.g., ...). Figure 8 An image of the fabric without shadows was obtained from the outer shell (C).

[0083] The device 100 may include at least one second light source (not shown) disposed on the extension 114 or the guide 120. The second light source may enhance the scanning performance of the fabric by the texture scanner 192 (e.g., Figures 5 to 7 The second light source may include an LED. The second light source may be configured to acquire an image of the fabric (FB) that is not shadowed by the texture scanner 192 or other components (e.g., extension 114, etc.) during the scanning of the texture by the texture scanner 192.

[0084] Figure 5 is a side view of the drape test device before the second mobile body is raised according to an embodiment. Figure 6 is a side view of the drape test device after the second mobile body is raised according to an embodiment. Figure 7 is a side view of the drape test device after the second mobile body is lowered according to an embodiment. Figure 8 is a perspective view of the drape test device according to an embodiment.

[0085] Referring to Figures 5 to 8 , the drape test process can be better understood. Referring to Figure 5 , to perform the drape test, a user can place a fabric FB on the first mobile body (e.g., the first mobile body 130 of Figure 7 ) and the second mobile body 140. The first mobile body can be supported by a protrusion (e.g., the protrusion 145 of Figure 3 ) and placed inside the first plate 141. The first mobile body can be located at a first height D1 from the base 111, and the first plate 141 can also be located at the first height D1 from the base 111. The user can place the fabric so that the center of the fabric is substantially identical to the center of the first mobile body by checking the position where the laser 180 irradiates the laser or the mark contained on the fabric. The second fixing member 152 can be provided at the lower end of the first mobile body. The second fixing member 152 can be substantially located on the central axis (e.g., the Z-axis) of the first plate 141.

[0086] Referring to Figure 6 , the actuator 160 can move the second plate 144 in a direction substantially opposite to the direction of gravity (e.g., the +Z direction) to position the first mobile body (e.g., the first mobile body 130 of Figure 7 ), the first plate 141, and the fabric FB at a second height D2 from the base 111. When positioned at the second height D2, the first mobile body can be fixed to the extension 114. The first mobile body can be fixed to the extension 114 by magnetically combining the first fixing member 151 and the second fixing member 152. When the first mobile body is positioned at substantially the second height D2, the second fixing member 152 can be moved to the first fixing member 151 by magnetism. When the second fixing member 152 is moved to the first fixing member 151, the first mobile body 130 can also be moved together. When the first plate 141 is positioned at the second height D2, the actuator 160 no longer moves the second plate 144. When the first mobile body and the first plate 141 are positioned at the second height D2, the coupler 170 can couple the fixed body 110 and the second mobile body 140. Even though the actuator 160 no longer moves the second plate 144, the height of the second mobile body 140 can be maintained at the second height D2 by the coupler 170.

[0087] Referring to Figure 7 During the process of fixing the first mobile body 130 and the fabric FB to the extension 114, the second mobile body 140 can move (e.g., descend) relative to the first mobile body 130 along a substantially gravity direction (e.g., -Z direction). The second mobile body 140 can descend to a position at a first height D1 from the base 111. As the area of the fabric FB supported by the second mobile body 140 relaxes, the area of the fabric FB hanging down can form a plurality of wrinkles. The camera 190 can acquire images of the fabric FB. The second mobile body 140 can move to a second height D2 at which the first mobile body 130 and the fabric FB are fixed. Then, the first mobile body 130 and the second mobile body 140 can slowly return to the first height D1.

[0088] Referring to Figure 8 The apparatus 100 can include an outer cover C for blocking light from outside. The outer cover C can be detachably connected to the fixed body 110. During the process of performing the drape test, the user can use the outer cover C to reduce or eliminate background noise. The outer cover C can have a color (e.g., black) with a lower saturation than the saturation of the fabric FB. The surface of the outer cover C can include a paint with a lower saturation color. This helps to improve the recognition of the optical device (e.g., the camera 190) for the fabric of the outer cover C. For example, the outer cover C can be anodized. Even without the outer cover C, the user can perform the drape test. Figures 5 to 7 Although the drape test is performed without the outer cover C, the user can also perform the Figures 5 to 7 drape test process shown in FIG. 10 in a state in which the outer cover C and the fixed body 110 are combined.

For example, the described techniques are performed in a different order from the described method, and / or the described system, structure, apparatus, circuit, etc. constituent elements are combined or combined in a different form from the described method, or replaced or replaced by other constituent elements or equivalents, and appropriate results can be obtained.
