Technical Field

[0001] This utility model belongs to the field of sampling instrument technology, specifically relating to a digital material sampling instrument for shoe fabric. Background Technology

[0002] A digital material sampler for shoe uppers is a specialized device that converts the physical appearance and texture (such as color, texture, gloss, and unevenness) of physical shoe upper materials into high-precision digital data. Using multi-angle lighting and imaging technology, the sampler collects optical data from the material surface. Then, through BRDF model calculations, it decomposes and reconstructs the material's physical properties, including color, texture, unevenness, and gloss. Finally, it outputs a set of digital material maps that can be used for 3D rendering, thus achieving a precise and efficient transfer of shoe upper materials from the physical world to the digital world.

[0003] The existing digital material samplers for shoe uppers are almost monopolized by foreign companies and are expensive, which greatly increases the cost of use for users. Therefore, it is necessary to design a digital material sampler for shoe uppers that is low in cost, easy to operate, and has high sampling accuracy. Summary of the Invention

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figure 1-3 As shown, a digital material sampler for shoe fabric includes: a base 1, which houses a control and calculation module 2; a sample carrier platform 3, mounted on the base 1, for placing the shoe fabric 4 to be sampled; a lamp holder 5, arranged around the sample carrier platform 3; multiple lighting units 50, circumferentially distributed on the lamp holder 5, and independently controllable by the control and calculation module 2; an image acquisition device 6, positioned above the lamp holder 5, with its lens facing the center of the sample carrier platform 3; and a darkroom housing 7 covering the sample carrier platform 3 and the lamp holder 5; the inner side of the lamp holder 5 is also provided with a soft light cover 8 that softens and guides the light emitted by each lighting unit 50 to the sample carrier platform 3. The sample carrier platform 3 includes a tray 31 and a light-transmitting plate 32, the light-transmitting plate 32 being located in the center of the tray 31 and used to place the shoe fabric 4 to be sampled. Placing the shoe fabric to be sampled on the light-transmitting plate ensures that the shoe fabric can be placed flat on the sample carrier platform, thereby facilitating the sampling of the shoe fabric.

[0022] like Figure 2 and 3As shown, a slot 100 is formed between the base 1 and the darkroom housing 7, and the tray 31 is inserted into the slot 100. The tray is connected to the slot by a plug-in method, which facilitates the placement or removal of the shoe material to be sampled. When placing the shoe material to be sampled, the tray is pulled out of the slot, the shoe material to be sampled is placed on the light-transmitting plate, and then the tray is inserted into the slot to sample the shoe material, making the operation more convenient. The darkroom housing 7 is provided with multiple buckles 71, and the base 1 is provided with multiple slots 11 that engage with the multiple buckles 71. The darkroom housing and the base are connected by a buckle, which facilitates the assembly of the darkroom housing and the base and improves assembly efficiency. A bottom lighting component 9 is provided inside the base 1 directly below the light-transmitting plate 32, and the control calculation module 2 is configured to independently control the bottom lighting component 9. The bottom lighting assembly 9 includes a base cover 91 housed within the base 1, a panel light 92 housed within the base cover 91, and a transparent light plate 93. The transparent light plate 93 is mounted on the base cover 91 and covers the panel light 92. The panel light 92 is a surface light source, and its light-emitting surface area is not less than the area of ​​the light-transmitting plate 32. The base cover 91 has multiple heat dissipation holes 911 arranged in an array. When the shoe fabric to be sampled has a transparent part, the control calculation module controls the bottom lighting assembly to turn on. The light source of the panel light of the bottom lighting assembly illuminates the light-transmitting plate, thereby enabling the material of the shoe fabric to be sampled with a transparent part, which is beneficial to improving the sampling accuracy. The heat dissipation holes are beneficial to the heat dissipation of the panel light, which is beneficial to improving the working reliability of the digital material sampler for shoe fabric. The lamp holder 5 is a regular octagonal frustum-shaped ring frame, and the soft light cover 8 is a frustum-shaped cover. The lighting unit 50 consists of 8 light plates 51 respectively mounted on the periphery of the lamp holder 5, and each light plate 51 has multiple LED beads 52 arranged in an array. The design employs multiple illumination units, enabling multi-angle image acquisition and improving sampling accuracy.

[0023] like Figure 3 As shown, two light guide plates 53 are arranged on both sides of each light panel 51 inside the lamp holder 5. The light guide plates can guide the light from the lamp beads to the sample support stage, thereby improving the illumination efficiency. The image acquisition device 6 is a high-definition camera, which is set at the top of the lamp holder 5. The use of a high-definition camera to photograph the shoe fabric to be sampled helps to improve the sampling accuracy of the digital material sampler for this fabric. The control calculation module 2 is configured to perform the following operations: control each lighting unit 50 to be grouped or lit individually in a preset order; control the image acquisition device 6 to perform synchronous image acquisition when each lighting unit 50 is lit; and store or transmit the acquired multi-angle image sequence. The control calculation module can adjust the light combination of multiple lighting units according to the photosensitivity of the shoe fabric to be sampled, thereby improving the sampling accuracy of different photosensitivity shoe fabrics.

[0024] This digital material sampler for shoe fabrics employs a multi-angle image acquisition structure. Through a surround, controllable lighting system, coupled with a top-mounted high-definition camera, the combination of multiple lighting units can be adjusted according to the photosensitivity of the shoe fabric to acquire image data of the fabric under different lighting angles, laying the foundation for subsequent digital material generation. This structure is simple in design, easy to operate, and low in cost, effectively improving the accuracy of shoe fabric sampling.
