[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0042] Augmented Reality (AR) technology refers to the real-time interaction of information and data by superimposing virtual information with real environment images. The virtual-real blend of augmented reality turns the entire world around the user into an interactive object, becoming a new mode of information interaction. The application scope of augmented reality technology in life is becoming wider and wider.
[0043] Chain-like objects refer to objects with a chain-like structure, such as bracelets, necklaces and other accessories.
[0044] Physical simulation refers to a simulation experiment based on the similarity of physical quantities between the physical model and the prototype. Specifically, the physical model is established based on the similarity theory. The laws between certain quantities obtained from experiments on the physical model are then deduced back to the prototype, thereby gaining an understanding of the regularity of the prototype.
[0045] In the field of virtual jewelry trying on, currently only cloth simulation algorithms are used to physically simulate virtual jewelry, that is, virtual jewelry is simplified into thin cloth strips. However, since the movement characteristics of virtual jewelry are different from those of cloth, the current virtual jewelry trying on effect is not good.
[0046] To this end, the embodiment of the present disclosure provides a chain object display method. When a preset interaction request for a target chain object is received, the physical model of the target chain object is first obtained, wherein the physical model is composed of line segments obtained by modeling the target chain object and multiple pendant nodes, and the multiple pendant nodes respectively form triangles with the corresponding line segments. Secondly, based on the image to be processed, the rotation angle information of the line segments corresponding to the pendant nodes in the physical model of the target chain object is obtained, and based on the rotation angle information of the line segments corresponding to the pendant nodes, the rotation angle information of each line segment in the physical model is calculated, and then, the target chain object is physically simulated based on the rotation angle information of each line segment. The embodiment of the present disclosure models the target chain object into a physical model including line segments and multiple pendant nodes, and the pendant nodes and the corresponding line segments form a triangle, forming a stable constraint on the radial direction of the line segment. Based on the stable constraint formed on the radial direction of the line segment, the target chain object is displayed, which can improve the physical simulation effect of the target chain object, thereby improving the virtual try-on effect presented to the user.
[0047] In addition, since the physical model of the target chain-like object in the embodiment of the present disclosure is composed of one-dimensional line segments, physical simulation of the target chain-like object based on the physical model designed in the embodiment of the present disclosure can optimize system performance to a large extent.
[0048] Based on this, the present disclosure provides a method for displaying chain-like objects. Figure 1 , is a flow chart of a chain object display method provided by an embodiment of the present disclosure, the method specifically comprising:
[0049] S101: In response to a preset interaction request for a target chain-like object, a physical model of the target chain-like object is acquired.
[0050] The physical model is composed of line segments obtained by modeling the target chain-like object and a plurality of pendant nodes, and the plurality of pendant nodes respectively form triangles with the corresponding line segments.
[0051] The chain object display method provided by the embodiment of the present disclosure can be applied to a terminal device, such as a client device deployed with the chain object display method. The target chain object may include objects with a chain structure such as necklaces and bracelets, and the pendant node refers to a pendant on the target chain object, such as a pendant on a necklace or bracelet.
[0052] In the disclosed embodiment, the target chain-like object is modeled in advance to obtain a physical model of the target chain-like object, and a corresponding relationship between the target chain-like object and the physical model is established.
[0053] Specifically, in the modeling process, a plurality of line segments having a connection relationship and forming a chain structure are used to simulate the target chain object, and the pendant objects in the target chain object are simulated as pendant nodes to obtain a physical model of the target chain object.
[0054] Distance constraints are set between the connected line segments in the physical model to form a ring structure. If physical simulation is performed based only on distance constraints, it is easy to cause the target chain object in the physical simulation effect to have abnormal simulation states such as wrong flipping posture and frequent changes. Therefore, the embodiment of the present disclosure adds a pendant node to the physical model. Under the influence of gravity and support force (such as the support force provided by the neck and wrist, etc.), the posture of the target chain object at the pendant node is credible. For example, when trying on a bracelet, if you keep flipping your wrist, the bracelet will present a posture that conforms to the actual situation.
[0055] like Figure 2, which is a schematic diagram of a physical model of a target chain-like object provided by an embodiment of the present disclosure, wherein the physical model of the target chain-like object is composed of line segments (including line segment 1) obtained by modeling the target chain-like object and a plurality of pendant nodes (including pendant node 1 and pendant node 2), each pendant node and the corresponding line segment form a triangle, such as pendant node 1 and line segment 2 forming a triangle, see Figure 2 As shown in the dashed box, the triangular structure has stability, therefore, the embodiment of the present disclosure forms radial stability constraints on the line segment by constructing a triangle.
[0056] In the disclosed embodiment, the physical model of the target chain-like object may include only the first type of pendant nodes. In addition, the physical model of the target chain-like object may include the first type of pendant nodes and the second type of pendant nodes. The first type of pendant nodes are pendant nodes obtained by modeling the pendant objects in the target chain-like object, and the second type of pendant nodes are virtual nodes added in the physical model.
[0057] In an optional implementation, if the target chain-like object does not have a pendant object, that is, the prototype of the chain-like object does not have a pendant object, a virtual pendant node can be added to the physical model so that the target chain-like object includes multiple pendant nodes. If the number of pendant nodes in the physical model is not greater than a preset number threshold, at least one virtual node can be added to the physical model as a pendant node. The preset number threshold can be set based on demand, for example, it can be 2.
[0058] In order to ensure the physical model effect on the target chain-like object, the angle between adjacent pendant nodes in the physical model of the target chain-like object is not greater than a preset angle threshold, and the preset angle threshold may be 180 degrees, for example.
[0059] In another optional implementation, if the physical model obtained based on the prototype modeling of the target chain-like object does not have a pendant node or only includes one pendant node, a virtual pendant node can be added to the physical model so that the physical model includes multiple pendant nodes and the angle between adjacent pendant nodes is not greater than a preset angle threshold.
[0060] In addition, if the physical model obtained based on the prototype modeling of the target chain-like object includes multiple pendant nodes, but the angles between adjacent pendant nodes among the multiple pendant nodes are all greater than the preset angle threshold, it is also possible to add virtual pendant nodes to the physical model so that the angle between at least two adjacent pendant nodes in the physical model is not greater than the preset angle threshold.
[0061] In practical applications, the preset interaction request for the target chain-like object may include a try-on request for a target necklace, a target bracelet, etc. When the try-on request for the target necklace or the target bracelet is received, a physical model of the target necklace or the target bracelet is obtained.
[0062] S102: Based on the image to be processed, obtain the rotation angle information about the axis of the line segment corresponding to the pendant node in the physical model.
[0063] Among them, the target chain object is displayed on the image to be processed, and the image to be processed can be one frame or multiple frames of images, for example, one frame or multiple consecutive frames of video images, or one frame or multiple consecutive frames of real-time camera shooting images, etc.
[0064] In an optional implementation, when a preset interaction request for a target chain-like object is received, a physical model of the target chain-like object is obtained. In addition, a camera of the current device is turned on, and based on a camera shot, rotation angle information about an axis of a line segment corresponding to a pendant node in the object model is obtained.
[0065] For example, in a necklace try-on scenario, after the user clicks the try-on control for the target necklace, the camera is turned on to capture the user's necklace try-on position, such as the neck. Based on the camera's captured image, the user can adjust the virtual necklace's try-on angle, etc. For example, the user can adjust the necklace's pendant position. Based on the camera's captured image of the user adjusting the virtual necklace, the axial rotation angle information of the line segment corresponding to the pendant node in the physical model of the target necklace can be obtained. Specifically, by identifying the positions of the key points of the human body in the image captured by the camera (such as using the nodes of the neck and head as the positions of the key points of the human body in the necklace try-on scenario, and using the nodes of the arm, wrist, finger, etc. as the positions of the key points of the human body in the bracelet try-on scenario), the axial rotation angle of the line segment corresponding to the pendant node in the physical model of the target necklace can be obtained. In addition, the implementation method of how to obtain the axial rotation angle information of the line segment corresponding to the pendant node in the physical model based on the camera's captured image is not limited in the embodiments of the present disclosure.
[0066] like Figure 2 As shown, it is assumed that the rotation angle of the line segment (line segment 2) corresponding to the pendant node 1 is A, and the rotation angle of the line segment (line segment 3) corresponding to the pendant node 2 is B.
[0067] S103: Based on the axis rotation angle information of the line segment corresponding to the pendant node, determine the axis rotation angle information of each line segment in the physical model.
[0068] In the disclosed embodiment, after obtaining the axis rotation angle information of the line segments corresponding to the pendant nodes in the physical model of the target chain-like object, the axis rotation angle information of other line segments in the physical model is calculated based on the axis rotation angle information of the line segments corresponding to each pendant node.
[0069] In an optional implementation, the interpolation calculation method can be used to calculate the rotation angle information of other line segments in the physical model. Specifically, the interpolation calculation is performed based on the rotation angle information of the line segments corresponding to the pendant nodes in the physical model to obtain the rotation angle information of each line segment.
[0070] like Figure 2 As shown, assuming that the axis rotation angle of the line segment corresponding to pendant node 1 (line segment 2) is A, and the axis rotation angle of the line segment corresponding to pendant node 2 (line segment 3) is B, then the line segments between line segment 2 and line segment 3 can be obtained based on interpolation calculation. Assuming that there are three line segments between line segment 2 and line segment 3, the axis rotation angles of these three line segments are A+(|AB| / 5), A+2×(|AB| / 5) and A+3×(|AB| / 5) respectively.
[0071] In another optional implementation, other algorithms may be used to calculate the rendering angle information of other line segments based on the rotation angle information of the line segment corresponding to the pendant node. For example, the physical simulation in the embodiment of the present disclosure is implemented using a rigid body collision simulation or cloth simulation algorithm, and the physical simulation result includes the rotation angle information of each line segment. The embodiment of the present disclosure does not limit the method for determining the rendering angle information of each line segment.
[0072] S104: Displaying the target chain-shaped object based on the rotation angle information about each line segment in the physical model.
[0073] In the disclosed embodiment, after obtaining the rotation angle information of each line segment in the target chain-like object, a physical simulation algorithm can be used to perform physical simulation on the target chain-like object, thereby more realistically simulating the prototype motion state of the target chain-like object to enhance the authenticity of the display of the target chain-like object.
[0074] In the disclosed embodiment, based on the rotation angle information about each line segment in the physical model, a physical simulation is performed on the target chain-like object to obtain a physical simulation result; then, the target chain-like object is displayed according to the physical simulation result.
[0075] In an optional implementation, a distance constraint condition is set between adjacent line segments in the physical model of the target chain-like object, which is used to constrain the distance relationship between adjacent line segments during the physical simulation process. Wherein, adjacent line segments refer to line segments with a connection relationship, such as Figure 2 Based on the distance constraint and the rotation angle information of each line segment in the physical model, cloth simulation is performed on the target chain-like object to obtain a physical simulation result, thereby realizing physical simulation of the target chain-like object.
[0076] In another optional implementation, in addition to using the cloth simulation algorithm, other physical simulation algorithms may also be used, which is not limited in the embodiments of the present disclosure.
[0077] In the disclosed embodiment, by setting distance constraints between line segments with connection relationships in the physical model, axial stability constraints are implemented on the line segments in the physical model. In addition, pendant nodes and corresponding line segments form triangles to implement radial stability constraints on the line segments in the physical model. Based on the above-mentioned axial and radial constraints, physical simulation of the target chain-like object is performed, which can more realistically simulate the real display effect of the target chain-like object.
[0078] In the chain object display method provided by the embodiment of the present disclosure, when a preset interaction request for a target chain object is received, the physical model of the target chain object is first obtained, wherein the physical model is composed of line segments obtained by modeling the target chain object and a plurality of pendant nodes, and the plurality of pendant nodes respectively form triangles with the corresponding line segments. Secondly, based on the image to be processed, the rotation angle information of the line segments corresponding to the pendant nodes in the physical model of the target chain object is obtained, and based on the rotation angle information of the line segments corresponding to the pendant nodes, the rotation angle information of each line segment in the physical model is calculated, and then, the target chain object is displayed based on the rotation angle information of each line segment. The embodiment of the present disclosure models the target chain object into a physical model including line segments and a plurality of pendant nodes, and the pendant nodes and the corresponding line segments form a triangle, forming a stable constraint on the radial direction of the line segments, and based on the stable constraint formed on the radial direction of the line segments, the target chain object is physically simulated, which can improve the physical simulation effect of the target chain object, thereby improving the display effect of the target chain object.
[0079] On the basis of the above-mentioned embodiments, the chain-like object display method provided by the embodiments of the present disclosure can be applied to try-on scenarios, for example, try-on scenarios of necklaces, bracelets, etc.
[0080] Specifically, in response to a request for trial wearing of the target chain-like object, the physical model of the target chain-like object is obtained. During the trial wearing process, the camera captures the trial wearing picture in real time, and based on the trial wearing picture captured by the camera in real time, the rotation angle information about the axis of the line segments corresponding to at least two pendant nodes in the physical model of the target chain-like object is obtained. Specifically, the method for obtaining the rotation angle information about the axis is not limited. After obtaining the rotation angle information about the axis of the line segments corresponding to at least two pendant nodes in the physical model, the difference calculation method is used to calculate the rotation angle information about the axis of each line segment in the physical model based on the rotation angle information about the axis of the line segments corresponding to the pendant nodes. After obtaining the rotation angle information about the axis of each line segment in the physical model, the target chain-like object is physically simulated. Then, the target chain-like object after physical simulation is rendered, and the trial wearing effect of the target chain-like object is displayed on the interface.
[0081] Since the embodiment of the present disclosure models the target chain-like object as a physical model including line segments and multiple pendant nodes, and the pendant nodes and the corresponding line segments form a triangle to achieve radial stability constraints on the line segments, therefore, on the basis of the distance constraints between adjacent line segments, adding radial stability constraints on the line segments can enhance the physical simulation effect of the target chain-like object, thereby enhancing the user's trial wearing effect.
