Detailed ways
[0027]
It will now be described with reference to the accompanying drawings of embodiments of the present invention. Elements and features of the elements and features described in one figure or one embodiment of the present invention may be illustrated embodiment with one or more other drawings or embodiments described combination. It should be noted that for purposes of clarity, the drawings and the description is omitted irrelevant to the present invention, shown and described are known to those of ordinary skill in the components and processes.
[0028]
As shown in FIG. 1, the processing circuit 110 according to the information processing apparatus 100 according to the present embodiment comprises. For example, the processing circuit 110 may be implemented as a particular chip, the chip set or a central processing unit (CPU) and the like.
[0029]
Processing circuit 110 includes a generating unit 111 and a control unit 113. It is noted that, while the figures in the form of a functional block diagram of a generating unit 111 and a control unit 113, it should be appreciated that the function generation unit 111 and the control unit 113 may be implemented by a whole as the processing circuit 110, and the It is not necessarily realized by the processing circuit 110 actually separate member. Further, although FIG illustrated blocks to a processing circuit 110, however, the information processing apparatus 100 may include a plurality of processing circuits, and the function generation unit 111 and the control unit 113 may be distributed to a plurality of processing circuits, so that a plurality of processing circuit cooperate to perform these functions.
[0030]
Generating unit 111 is configured while maintaining the three-dimensional model of the shape of at least a portion of the same semantics, to eliminate at least a portion of the local detail, to generate a modified version of the three-dimensional model.
[0031]
The information processing apparatus according to the present embodiment may be used, for example, a three-dimensional model of the service side, three-dimensional model for the distributed request that the recipient of the three-dimensional model. Accordingly, the modified version may be used to preview the recipient. Thus, hereinafter, a modified version of three-dimensional models may also be a "preview version."
[0032]
Further, the shape remains the same semantics means that eliminates the three-dimensional model of the portion of local details still contains basic semantic information to eliminate the portion of the local detail before.
[0033]
For example, if a detailed three-dimensional model of the object to eliminate the processing section for the car, then, if the object is processed still exhibits the shape of an automobile, the process remains the same shape of the object semantics. Conversely, if the object is processed into a rectangular shape such as a class, can not recognize that the object is a car in accordance with the shape, the process is not held constant shape of the semantic object.
[0034]
According to a particular embodiment, the generating unit 111 can be smooth, the vertex removal, and three-dimensional mesh simplification one or more to eliminate local details.
[0035]
Specifically, using a variety of methods known in the art for smoothing, the vertex removal or three-dimensional mesh simplification operations. By way of example, FIGS. 16A and 16B illustrate details of an example three-dimensional model of the part through the grid obtained by a simplified process and canceling effect, wherein using rabbit Stanford (Stanford Bunny, https: //graphics.stanford.edu/data/3Dscanrep) as an example 3D model. 16A shows a front object mesh simplification, FIG. 16B shows the target mesh simplification. Compared with the object of FIG. 16A, FIG. 16B through mesh simplification objects contain less detail. However, the object still contains the same as FIG. 16B and FIG. 16A target basic semantic information, i.e., both the shape of the rabbit.
[0036]
There are various modifications means to eliminate the three-dimensional model of local details. Depending on the shape of the three-dimensional model or part thereof semantics carried by the means of these modifications, there are differences in the role of the semantics of the three-dimensional model shape retention. According to a particular shape may be previously semantic three-dimensional model or part thereof is carried out to screen means adapted to modify.
[0037]
Referring back to FIG 1, the control unit 113 is configured to control to the modified version, and recover the transmitted information to the receiver. Among them, restore the original version information is used to restore a modified version of a three-dimensional model. In other words, the details of the local recovery unit 111 for generating the cancellation related to the process can be carried out, for example, by eliminating the corresponding local details based on the local details of the recovery process to restore the original information to obtain a three-dimensional model.
[0038]
By the above-described embodiment, the three-dimensional model preview provided to the recipient, the preview version compared to the original three-dimensional model having a reduced level of detail, but maintaining the original three dimensional shape of the semantic model. Therefore, to ensure data security in the original three-dimensional model at the same time, the recipient does not affect the overall preview of the three-dimensional model, and thus more conducive to the recipient to decide whether authorized (eg purchase) of the original three-dimensional model. On the other hand, for acquiring authorized recipient through a preview version, sending only a small amount of the subsequent data recovery information, the communication load can be reduced.
[0039]
Next, according to an embodiment of the present invention, three-dimensional model to be protected is processed to generate a preview version of the example process. It should be understood that the invention is not limited to the details the following examples.
[0040]
First, a three-dimensional grid of the original three-dimensional model. Next, the generated three-dimensional network such as Evolved simplified encryption method. The particular method of merging adjacent mesh vertex, mesh edge to eliminate grid Gaussian smoothing the like (e.g., see "Encryption of Progressive Meshes", www.cosy.sbg.ac.at / ~ uhl / SEVCM / Fr_Vo_3_mesh_encrypt.pdf and the "Encryption for Profiling Preserving the Geometry-3D Meshes, Marcéluard, Yves Maetz, COMPRESSIon REprésentation et des Signaux Audiovisuels (CORESA), 2013"). In the simplified process, for example, can be controlled (e.g., by controlling the combined number or proportion of vertices, the eliminated sides of the number or proportion, degree of smoothing or the like) of mesh simplification extent by an automatic or semiautomatic manner, so that the shape of the object to maintain the semantics of the same process.
[0041]
Further, for example, you can keep the original version with the preview version of the difference data as the resume information. According to some embodiments, the restoration data may be encrypted, for example, where encryption using conventional data encryption techniques. Then embedded, difference data may be sent to authorized receivers, or may be, for example, by way of a three-dimensional watermark is encrypted difference data to a simplified model.
[0042]
FIG 13 illustrates an exemplary process carried out between the three-dimensional model and the receiver service interaction. Among them, for example, the service side can provide a three-dimensional model of the server, the recipient may include, for example, three-dimensional printing collaborative manufacturing, design three-dimensional model of shared party or parties to the transaction, or three-dimensional model of experience related merchandise buyer, and so on.
[0043]

The request information may comprise identification information indicating the identity of the recipient and the like. In S1310, the principle of service to the recipient requesting authentication process. In addition, S1308 to S1310 process may also involve the processes related to the purchase of the original model.
[0046]
In the case where the authentication process by the S1310, and in S1312, the service recovery information sent to the recipient, the recovered version information is used to restore a simplified model for the preview portion of the original high level of detail. In S1314, the receiving side restores the original model using the restoration information.
[0047]
In the process, it has not been authorized recipient can only view a preview version of the three-dimensional model, thus ensuring the data security of the original three-dimensional model. And, thereafter for the reception side certified (e.g., the user who purchased the original three-dimensional model), only a relatively small amount of transmission data recovery information, thus reducing the communication load distribution authorization operation of the 3D model.
[0048]
Further, according to one embodiment, the recovery information may be encrypted to further improve security of data of the original three-dimensional model.
