[0002] With the continuous improvement of technology and people's growing user needs, more and more users buy clothes online. However, online shopping now refers to clothing display pictures directly, or refers to the fitting effects of models in the live broadcast room to determine whether to buy.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0076] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0077] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0078] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0079] With the growth of technology and user demand, more and more users are pursuing efficiency in life. Compared with the traditional offline physical store shopping, more users choose online shopping. Users refer to the clothing display pictures on the purchase interface or the model fitting effects in the live broadcast room to choose whether to place an order. However, due to the lack of actual trying on, the return rate of online shopping clothes is relatively high.

[0080] The existing technology uses a 3D virtual fitting system to simulate the fitting effect of the user and the clothes they want to buy, so that the user can intuitively view the matching effect of the clothes without wasting time, which improves the user's shopping experience. However, this method is based on clothing photos and user photos. The modeling quality is closely related to the photo quality. However, when the shooting environment is not well lit, the shadow on the clothing picture is large, which reduces the modeling quality of the three-dimensional model and reduces the user experience.

[0081] The present application provides a clothing image acquisition method, which obtains the target fill light position according to the brightness difference between the brightness of the clothing in the initial clothing picture sent by the clothing image acquisition device and the final brightness, obtains the target fill light brightness according to the clothing color in the initial clothing picture and the final brightness, sends the target fill light position and the target fill light brightness to the clothing image acquisition device, and obtains the target clothing picture with the clothing brightness as the final brightness according to the returned picture. Through the above method, the image information obtained by the clothing image acquisition device is illuminated evenly, the modeling quality of the three-dimensional model obtained according to the image is improved, and the user experience is improved at the same time.

[0082] Next, the technical solution shown in the present application is described in detail through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0083] Figure 1 This is a schematic diagram of the structure of a clothing image acquisition device provided in an embodiment of the present application. Figure 1 As shown, the clothing image acquisition device includes: a base, a mannequin, a fill light, a counterweight and a support rod, wherein:

[0084] The fill light is slidably connected to the edge of the base, the support rod and the counterweight are arranged relative to the base, the shooting device is fixed on the support rod, and the base is used to place the mannequin. The fill light includes a lamp pole and a plurality of bulbs, the bulbs are fixed on the lamp pole, and the bulbs are used to adjust the brightness of the fill light.

[0085] In this embodiment, the specific steps of adjusting the brightness of the fill light are:

[0086] Adjust the switch status of multiple bulbs fixed on the light pole to make the fill light brightness equal to the target fill light brightness. At the same time, the bulb can be selected with multiple brightness levels, and the brightness of the fill light of the clothing image acquisition device can be made equal to the target fill light brightness by combining the bulb level and the number of bulbs turned on.

[0087] Figure 2 A schematic diagram of a method for collecting clothing images is provided in the present application. Figure 1 .like Figure 2 As shown, the method includes:

[0088] S201. Acquire an initial clothing picture sent by a clothing image acquisition device, wherein the initial clothing picture is a picture of clothing acquired when the clothing image acquisition device does not turn on a fill light.

[0089] In this step, the initial clothing photo is used to obtain the target fill light brightness. After the clothing image acquisition device acquires the initial clothing photo, the initial clothing photo can be directly connected to upload to the server, or the user can operate to upload the initial clothing photo to the server.

[0090] Furthermore, when the clothing image acquisition device acquires clothing, the fill light needs to be turned off. This embodiment does not make any requirements on the position of the fill light for taking the initial clothing photo.

[0091] S202. Acquire clothing information of the clothing according to the initial clothing picture, where the clothing information includes clothing brightness and clothing color.

[0092] In this step, in order to improve the quality of the three-dimensional model obtained by modeling the initial clothing picture, the initial clothing picture needs to be clear, that is, the clothing in the initial clothing picture can fully present the details of the clothing. In order to achieve the requirement that the clothing in the initial clothing picture can fully present the details of the clothing, the brightness and saturation of the clothing in the initial clothing picture are required to be within an appropriate range.

[0093] Furthermore, since the intensity of natural light may not meet this requirement, it is necessary to use the fill light of the clothing image acquisition device to adjust the brightness and saturation of the clothing in the clothing photo. The brightness of the fill light needs to be adjusted according to the color of the clothing itself, so it is necessary to obtain the brightness and color of the clothing in the initial clothing picture.

[0094] Among them, since most clothes contain more colors, this embodiment adopts different color selection strategies according to the number of colors contained in the clothes. When the color of the clothes is a pure color, the pure color is the color of the clothes; if the color of the clothes is a non-pure color, the color system with the largest proportion of the clothes is the color of the clothes. For example: the clothes are 30% orange, 20% red, 35% yellow, and 15% red, then the color of the clothes is red.

[0095] Specifically, the steps of obtaining clothing brightness according to the initial clothing image are:

[0096] Converting the initial clothing image from the RGB space to the HIS space, wherein the RGB space is used to display the color of the image and the HIS space is used to display the brightness of the image;

[0097] Dividing the converted initial clothing image into a plurality of areas to be adjusted by a detection frame, wherein the detection frame is a rectangular area containing a plurality of grids, and the number of the areas to be adjusted is the same as the number of the grids;

[0098] The brightness of the clothes in each of the areas to be adjusted is obtained.

[0099] S203. Acquire fill light information of the clothing image acquisition device according to the clothing information and the target brightness, where the fill light information includes target fill light brightness and target fill light position.

[0100] In this step, the target brightness is the brightness that can clearly show the details of the clothing, that is, the brightness of the final clothing image used for modeling. This embodiment does not impose any limitation on the target brightness, and it can be selected according to actual conditions.

[0101] Specifically, the corresponding target fill light brightness can be obtained from the shooting knowledge base according to the color of the clothing, and the shooting knowledge base is a priori shooting experience. The obtained target fill light brightness is sent to the clothing image acquisition device, and a new clothing photo captured at this brightness is obtained. The target fill light position is obtained according to the brightness difference between the brightness of the clothing in the new clothing photo and the target brightness.

[0102] Furthermore, since the brightness of the fill light received by the clothes is inconsistent, the brightness of the clothes in the new clothes photo may be inconsistent. The brightness of the clothes corresponding to each grid can be obtained through the detection frame, and the average brightness can be calculated based on the brightness of multiple clothes, and the average brightness can be used as the brightness of the new clothes photo; the target fill light position corresponding to each grid can also be obtained based on the brightness of the clothes corresponding to each grid.

[0103] S204. Acquire a target clothing picture according to the candidate clothing photos sent by the clothing image acquisition device, wherein the candidate clothing photos are photos acquired by the clothing image acquisition device according to the fill light information.

[0104] In this step, when the average brightness is used as the brightness of the clothing, the target fill light position is obtained as one, and the candidate photo collected according to the fill light information is the target clothing photo.

[0105] Furthermore, when the new clothing image is split into multiple parts, multiple target fill light positions are obtained, and each grid of the detection frame corresponds to a target fill light position. That is, multiple candidate clothing photos are obtained based on the fill light information, and the target clothing photo is obtained by splicing the candidate clothing photos.

[0106] The present application provides a clothing image acquisition method, which obtains the target fill light position according to the brightness difference between the brightness of the clothing in the initial clothing picture sent by the clothing image acquisition device and the final brightness, obtains the target fill light brightness according to the clothing color in the initial clothing picture and the final brightness, sends the target fill light position and the target fill light brightness to the clothing image acquisition device, and obtains the target clothing picture with the clothing brightness as the final brightness according to the returned picture. Through the above method, the image information obtained by the clothing image acquisition device is illuminated evenly, the modeling quality of the three-dimensional model obtained according to the image is improved, and the user experience is improved at the same time.

[0107] Figure 3 A schematic diagram of a method for collecting clothing images is provided in the present application. Figure 2 The embodiment of the present application provides a detailed description of the steps of how to obtain the target fill light brightness and the target fill light position. Figure 3 As shown, the method includes:

[0108] S301. Obtain a target brightness range corresponding to the target brightness, obtain a corresponding natural light intensity range according to the natural light intensity, and obtain the target fill light brightness from a preset relationship according to the target brightness range, the natural light intensity range and the clothing color.

[0109] In this step, in order for the clothing image captured by the clothing image acquisition device to better show the characteristics of the clothing, the light of the fill light needs to be adjusted according to the parameters of the clothing itself and the light environment of the shooting location. Therefore, this embodiment obtains the target fill light brightness according to the target brightness, natural light intensity and clothing color.

[0110] Specifically, since the range of natural light intensity and target brightness is large, the natural light intensity and target brightness are divided into multiple ranges, and the target brightness of the fill light is obtained from the preset relationship according to the target brightness range corresponding to the target brightness, the natural light intensity range corresponding to the natural light intensity, and the color of the clothing. The preset relationship is used to indicate the relationship between the target brightness range, the natural light intensity range, the clothing color, and the target brightness of the fill light.

[0111] Furthermore, after obtaining the target fill light brightness, the service terminal sends the target fill light brightness to the clothing image acquisition device, first adjusts the fill light brightness to the target fill light brightness, and then obtains the target fill light position based on this brightness.

[0112] S302: Acquire multiple new clothing images sent by the clothing processing device, convert each of the new clothing images from the RGB space to the HIS space, and acquire the brightness of the new area to be adjusted according to the detection frame.

[0113] In this step, the new clothing picture is a picture obtained when the brightness of the fill light is the target fill light brightness and the fill light is at a preset position. The new clothing picture is used to obtain the target fill light position. This embodiment does not impose any limitation on the number and position of the preset positions. For example, the preset positions may be 4-5.

[0114] Furthermore, the number of the new clothing pictures is the same as the number of the preset positions. That is, each time the position of the fill light is adjusted, the clothing image acquisition device needs to capture a photo of the clothing and transmit the captured new clothing picture to the server. After receiving multiple new clothing pictures sent by the clothing image acquisition device, the clothing brightness of each new clothing picture is obtained. In this embodiment, the new clothing picture is split into multiple local pictures to obtain the clothing brightness of each local area, that is, the new clothing picture is divided into multiple new areas to be adjusted through the detection frame, and the clothing brightness of each new area to be adjusted is obtained. The specific operation steps have been described in detail in the aforementioned embodiment, so they will not be described in detail here.

[0115] S303, obtaining a brightness angle between a light irradiated by the fill light on the local clothing corresponding to each grid in the detection frame and a perpendicular line to the local clothing when the fill light is in the preset position.

[0116] In this step, when the fill light moves, the light received by the fill light at different parts of the clothing is inconsistent, and the brightness of the corresponding clothing is also inconsistent. Therefore, this embodiment divides the clothing into multiple grids of the detection frame, and calculates the rate of change of the brightness of the local clothing corresponding to each grid as the position of the fill light changes. Since the range of the local clothing is small, it is considered that the rate of change of the brightness of the local clothing corresponding to each grid as the position of the fill light changes is consistent.

[0117] S304: Obtain a brightness change rate corresponding to each grid according to the brightness of the plurality of areas to be adjusted corresponding to each grid and the brightness angle.

[0118] In this step, the brightness change rate is the amount of brightness change of the local clothing when the brightness angle corresponding to the vertical line between the fill light and the local clothing changes by one degree. The corresponding calculation formula is: brightness change rate = local clothing brightness change value / brightness angle change value.

[0119] Furthermore, there are N preset positions of the fill light, where N is an integer greater than or equal to 2. In order to make the calculated brightness change rate more accurate, N can be selected as a number greater than 2. The corresponding calculated brightness change rates are also multiple, and the multiple brightness change rates can be averaged, and the average brightness change rate is used as the brightness change rate corresponding to the grid.

[0120] For example: brightness angle 1: 15°,15, brightness angle 2: 30°45, the brightness angle change value is 15°, the brightness change value is 30, and the corresponding brightness change rate is 2. That is, for every degree change in the brightness angle, the brightness changes by 2. When the brightness angle is 0, the brightness of the local clothing is the starting brightness, that is, the brightness of the local clothing under natural light, and also the brightness of the area to be adjusted corresponding to the grid of the initial clothing photo.

[0121] S305. Obtain a target angle according to the brightness change rate and the target brightness, and obtain the target fill light position corresponding to each grid according to the target angle, so that a new brightness angle is equal to the target angle.

[0122] In this step, the target angle is the angle between the light from the fill light irradiating the local clothing and the vertical line of the local clothing when the local clothing brightness is the target brightness. The calculation process of the target angle is: (target brightness-initial brightness) / brightness change rate. Then, the target fill light position corresponding to each grid is obtained according to the target angle.

[0123] For example, when the initial brightness is 30, the target brightness is 50, and the brightness change rate is 2, the target angle = (50-30) / 2 = 10°. That is, the position of the fill light is obtained based on 10°.

[0124] The present application provides a method for capturing clothing images. First, the target fill light brightness is obtained according to the clothing color, target brightness and natural light intensity. At this brightness, the fill light position is adjusted to calculate the brightness change rate. Then, the target fill light position corresponding to the clothing brightness of each part of the clothing image is calculated when the clothing brightness is the target brightness. In this way, the clothing brightness in the clothing image is the target brightness that best presents the clothing effect. This improves the presentation effect of the clothing photo, and then improves the quality of modeling.

[0125] Figure 4 A schematic diagram of a method for collecting clothing images is provided in the present application. Figure 3 The embodiment of the present application provides a detailed description of the steps of how to obtain a target clothing photo according to the target fill light position. Figure 4 As shown, the method includes:

[0126] S401: receiving a plurality of candidate clothing photos sent by the clothing processing device.

[0127] In this step, when the server obtains the target fill light position corresponding to each grid, it sends it to the clothing image acquisition device, and the clothing image acquisition device controls the fill light to slide along the edge of the base until the current fill light position is the same as the target fill light position. The clothing image acquisition device then takes a photo of the clothing and sends it to the server, while controlling the fill light to move so that the new current brightness angle is the same as the next target fill light position, and takes a photo of the clothing until the fill light moves to each target fill light position and takes a photo.

[0128] When the server receives all candidate clothing photos sent by the clothing image acquisition device, it obtains the target clothing photo based on the multiple candidate clothing photos.

[0129] S402, obtaining a partial photo corresponding to each of the adjusted clothing photos, wherein the partial photo is obtained according to the grid corresponding to the adjusted clothing photo.

[0130] In this step, the brightness of the clothing in a certain partial clothing photo in each candidate clothing photo is the same as the target brightness. The partial clothing photo is the partial clothing photo corresponding to the grid corresponding to the candidate clothing photo.

[0131] Specifically, a detection frame is used to divide each candidate clothing photo, and a partial clothing photo corresponding to the grid corresponding to the candidate clothing photo is saved. The partial clothing photo is associated with the position of the corresponding grid and stored. The position of the grid is used to obtain the target clothing image later.

[0132] S403: stitching the partial photos together to obtain a target clothing photo.

[0133] In this step, when all candidate clothing photos have obtained corresponding partial clothing photos, the partial clothing photos are spliced ​​to obtain the target clothing picture. First, the image position bound to each partial clothing picture is obtained, and the image position is the position of the associated storage grid. The partial clothing picture is moved to the corresponding image position.
