Since it is performed by operating a keyboard, a mouse, or the like as the input means of the terminal, it is practically impossible to apply to the field of assembling the object.

Meanwhile, technologies for combining virtual reality with offline are also developing. For example, Korean Patent Laid-Open Publication No. 2005-0108569 et al. Proposes a technique of photographing a stereoscopic figure that can be grasped by a user and outputting it to a monitor of a terminal. However, this technique is only a combination of outputting the captured image and the virtual reality on the monitor, the identification accuracy is very low, it can output only a predetermined shape, it is pointed out that it is impossible to model substantially different shapes Has been.

Hereinafter, a three-dimensional shape modeling method and system using blocks according to embodiments of the present invention will be described with reference to the accompanying drawings.

In the following description, in order to clarify the understanding of the present invention, description of well-known technology for the features of the present invention will be omitted. The following embodiments are detailed description to help understand the present invention, and it should be understood that the present invention is not intended to limit the scope of the present invention. Therefore, equivalent inventions that perform the same functions as the present invention will also fall within the scope of the present invention.

In the following description, the same identification symbol means the same configuration, and unnecessary redundant descriptions and descriptions of well-known technologies will be omitted.

In the embodiment of the present invention, "communication", "communication network" and "network" may be used as the same meaning. The three terms refer to wired and wireless local and wide area data transmission and reception networks capable of transmitting and receiving files between a user terminal, a terminal of other users, and a download server.

1 and 2 are flowcharts of a three-dimensional shape modeling method using blocks according to an embodiment of the present invention.

As described below, the three-dimensional shape modeling method using a block according to an embodiment of the present invention, a sensor, a communication module (including a processor) included in the block, a communication means of the user terminal, a processor, an input means and It will be understood that it is performed by the output means.

First, referring to FIG. 1, in a three-dimensional shape modeling method using blocks according to an embodiment of the present invention, a sensing sensor installed on at least one surface of a block configured of at least one or more types may be used for access or contact between blocks. In operation S10, a detection signal indicating that the blocks are in contact with each other is generated.

In the present invention, the block refers to all objects that the user can contact with each other by holding or manipulating offline, and is composed of at least one kind. In production, a block may be configured in at least one kind according to a package.

The type of block is a concept of defining a type of a block that can be classified based on the size, shape, color, material, and the like of the block. For example, the type of block is defined according to the shape of a tetrahedron or a hexagonal body, the size of a large block or a small block, the color of all or each surface of the block, the material of a wooden block, an iron block, a plastic block, or the like. Can be.

In the following description, for convenience of description of each embodiment, a block having a hexagonal shape will be described as an example, but as mentioned above, different blocks according to the type of blocks are used for implementing each embodiment of the present invention. Of course it can.

In addition, the detection sensor includes all sensors capable of detecting the relative approach or contact between each side of the block. For example, all sensors including ultrasonic sensors, infrared sensors, piezoelectric sensors and the like can be used.

When a user moves a block so that two blocks contact each other based on one side of each block, a sensing sensor existing on the contacted surface of the two blocks approaches the surface of the other block to the surface on which the corresponding sensing sensor is installed. Or it is detected that the contact, accordingly generates a detection signal indicating this.

That is, step S10 may refer to a configuration in which only one sensing sensor generates a sensing signal, but it will be understood as a configuration in which each sensing sensor of two blocks to be touched generates a sensing signal.

On the other hand, the sensor is installed on at least one side, that is at least a portion of the block. Preferably, in order to ensure the diversity of the assembly of the block, a sensing sensor will be installed on all sides, but if there is a symmetrical surface without being distinguished by color or the like and does not cause a problem in shape modeling, The detection sensor may be installed on only one side.

On the other hand, when the sizes of the blocks vary, a block having a small surface area may be combined with a block having a large surface area. In this case, it is necessary to determine which part of the corresponding surface of the large block is in contact with the surface of the small block. To this end, in the present invention, among the surfaces constituting all blocks, a unit area that is the width of the minimum area may be set, and one sensing sensor may be installed for each unit area.

For example, in the rectangular face of the rectangular parallelepiped block, if the regular hexagonal block smaller than the rectangular parallelepiped block and having an area 1/2 of the rectangular face is present as the smallest block, the face is divided into two parts. One sensing sensor may be installed in each divided area, and two sensing sensors may be installed on a rectangular surface. By installing such a sensing sensor and performing the function of the following steps, it is possible to determine whether the cube block is in contact with any of the rectangular faces, and thus the three-dimensional modeling can be performed more accurately.

When a touch is detected and a sensing signal is generated through the step S10, the communication module installed in the block including the sensing sensor in which the sensing signal is generated, receives the generated sensing signal, and in this case, the touch is detected from the sensing signal. In operation S20, the contact data including the identification information regarding the plane and the identification information of the block is generated and transmitted to the processor installed in the user terminal.

In the present invention, the communication module, together with the wireless communication means for performing the step S20, generates a memory and contact data constituting the block and the block and storing the identification information on the surface on which the sensor is installed processor through the wireless communication means It will be understood that the concept includes a small processor that controls the transmission of contact data.

In the present invention, the wireless communication means will be understood as a concept including all communication means for transmitting and receiving data by performing a short range wireless communication method and other wireless communication methods. For example, various short range wireless communication methods such as Bluetooth, Zigbee, and other RF communication may be used, or other wireless communication methods such as Wi-Fi may be used.

In the memory of the communication module, identification information of a block in which the communication module is installed and identification information of a detection sensor installed in the block may be stored as information for identifying a surface on which the detection sensor is installed.

When the small processor of the communication module receives the detection signal, the contact information is generated by combining the identification information of the detection sensor included in the detection signal and the identification information of the block, and then transmitting the generated contact data to the processor of the user terminal through a wireless communication means. Done. Specifically, contact data is transmitted to the communication means of the user terminal via the wireless communication means, and the contact data is transmitted from the communication means to the processor.

In the above, the contact data includes the identification information of the sensing sensor, but the identification information of the sensing sensor may be included in the contact data by being processed into identification information about the surface of the block on which the touch is detected by the small processor of the communication module. Of course it will. It is also to be understood that the identification information about the face of the block on which the touch is sensed, in other words, can mean identification information about the area to which another block accesses or contacts.

As described above, the contact data generated in step S20 basically includes identification information about a surface on which a contact is detected and identification information of a block. In another embodiment of the present invention, the gyro sensor may be additionally installed in the block. The gyro sensor performs a function of generating information about the direction of the block. In this case, the contact data may further include information regarding the direction of the block.

In this case, in step S40 to be described below, the processor combines the extracted three-dimensional model information of the block to model the three-dimensional shape, by using the direction information of the block direction of the three-dimensional model information of the block (for example, rotation Direction and control.

When at least one contact data is transmitted to the processor through step S20, the processor identifies the blocks from the stored information stored in the user terminal by using the identification information of the blocks included in the contact data received from the communication module of the blocks. Extracting 3D model information of blocks corresponding to the information (S30) is performed.

A program for performing the functions of the present invention will be installed in the user terminal, and according to the program installation, 3D model information of blocks matching the identification information of each block will be stored. The processor extracts three-dimensional model information corresponding to the contact data from among the three-dimensional model information of the stored blocks through step S30.

As mentioned in step S10, when the surfaces of the blocks come into contact, the communication modules of the two blocks that are in contact will generate contact data. In other words, when two blocks make contact with one surface, two pieces of contact data are transmitted to the processor at that moment. Accordingly, the processor receives at least two pieces of contact data and extracts 3D model information of blocks corresponding to the data.

In the present invention, the 3D model information of the blocks stored in the user terminal will be stored based on the identification information of each block. The 3D model information may include at least one of 3D shape information, color information, and material information of the block. Of course, identification information (eg, identification information of a sensing sensor installed on the surface) of the surfaces constituting each block is also included in the 3D model information.

When the 3D model information corresponding to the touch detected block is extracted through the step S30, the processor uses the 3D model information of the extracted blocks, and the identification information regarding the plane of the touch detected blocks included in the contact data. By combining, by performing the step (S40) to model the three-dimensional shape combined blocks.

Modeling the three-dimensional shape, preferably means combining the three-dimensional model information in real time according to the contact of the blocks, and outputs it to the output means of the user terminal.

In performing the step S40, the processor specifically loads the 3D model information of the blocks extracted from the storage space of the user terminal first. Thereafter, among the information of the surfaces included in the 3D model information of the blocks, the information of the surface corresponding to the identification information about the surface on which the contact included in the contact data is detected is selected. At this time, the information of the selected surface will select the information of the two surfaces determined to be in contact in each block when performing the contact of the two blocks.

After that, the 3D model information of the blocks including the information of the surface corresponding to the contact detected surface is combined with the 3D model information of the blocks such that the 3D model information of the blocks is connected based on the detected contact surface. Upon completion of combining the 3D model information of all blocks included in all the contact data, the combined 3D model information is modeled into a 3D shape. Of course, the completion of the combination of all three-dimensional model information will be redone whenever a contact of a new block is detected.

Through the above process, the user combines various types of blocks that can be contacted and combined on the offline, and this combined state is reproduced graphically by the 3D shape modeling program of the user terminal.

Through this, even users with low understanding of the 3D shape modeling program can easily model their desired 3D shapes by connecting blocks.

In the above embodiment of the present invention, it can be expected that the three-dimensional shape modeling technology can be used in various fields. For example, a beginner can easily be used to model three-dimensional shapes to use three-dimensional printing techniques. In addition, in the education field, the learner combines the blocks, and the shape of the combined blocks is expressed in the output means of the terminal, so that it can be used as a spatial perceptual learning and a game in the education field using the same.

As described above, according to the present invention, the field of use of the 3D shape modeling technology can be extended and applied to an education field that should have a relatively low degree of difficulty, thereby maximizing the range of use of the 3D shape modeling technology.

Meanwhile, referring to FIG. 2, while performing step S40 of FIG. 1, when the processor detects that the contact between the blocks is released, the processor receives identification information regarding the surface of the block from which the release of the contact is detected from the communication module. Step S50 is performed.

The S50 step can be performed in various ways. For example, the sensing sensor generates a sensing signal when the surface is touched, and may be performed by receiving a signal indicating that generation of the sensing signal is stopped. In other words, the contact data is continuously transmitted to the processor while the contact of the block is maintained, and when the contact is released, the transmission of the contact data will be stopped. Through this, identification information regarding the face of the block on which release of the contact is detected may be received. Alternatively, when the contact is released, the sensing sensor generates a signal indicating that the contact has been released, and the processor may receive the signal in a manner similar to that described with reference to FIG. 1.

When the step S50 is performed, the processor performs a step of releasing the combination of the 3D model information of the blocks corresponding to the identification information on the plane of the block from which the release of the contact is detected among the extracted 3D model information (S60). Done.

On the other hand, when performing the step S60, the processor may perform the step (S70) of determining whether each of the additionally extracted three-dimensional model information, the block in which the contact with all blocks has been released (S70). .

As a result of performing step S70, when it is determined that there is a block in which contact with all blocks is released, the processor deletes three-dimensional model information corresponding to the block from the modeled three-dimensional shape to update the modeling of the three-dimensional shape. Step S80 may be performed. Blocks in which contact with all blocks has been released will be blocks that are not included in 3D shape modeling, and these blocks need not be output to the user terminal.

According to the embodiment of Figure 2, not only the coupling between the blocks, but also can determine the decombination of the block and reflect it to the three-dimensional shape modeling, there is an effect that the accuracy of the modeling is further increased.

Meanwhile, in order to expand the range of use of the three-dimensional shape modeling method using the blocks according to the embodiments of FIGS. 1 and 2, after the three-dimensional shape is modeled, the processor is modeled by receiving input from a user terminal. Providing an editing interface capable of editing the shape to the user terminal may be further performed. For example, an interface for modifying the shape of a block or the like may be provided.

3 is a block diagram of a three-dimensional shape modeling system using blocks according to an embodiment of the present invention. In the following description, the description of portions overlapping with the description of FIGS. 1 and 2 will be omitted.

As mentioned in the description of FIGS. 1 and 2, the block 10 includes a sensing sensor 11 and a communication module 12 to detect the contact between the surfaces. The contact data including the identification information about the detected surface and the unique identification information of the block is transmitted to the processor 23 of the user terminal 20 to the outside. As mentioned above, the communication module 12 is described as including a small processor, a wireless communication means, and a memory 13, but in FIG. 3 the memory 13 is shown in a separate configuration.

The user terminal 20 may include an input means 21, an output means 22, a processor 23, and a communication means 24. The communication means 24 performs a function of relaying data transmission and reception between the processor 23 and the communication module 12.

When each function of FIGS. 1 and 2 is performed by the processor 23, the result of performing the function will be output to the output means 22. FIG. That is, the result of modeling the three-dimensional shape will be output to the output means 22, and the editing interface can be output. In the editing interface, the editing function input through the input means 21 will be performed.

That is, as mentioned in the description of FIGS. 1 to 2, block 10 is disposed on at least a portion (eg, one surface) of block 10, and other blocks may approach or contact within a certain distance. In this case, together with the detection sensor 11 that detects this, when detecting the approach or contact of another block, the identification information of the block 10 and the identification information regarding the area where the other block is approaching or contacting (for example, the contact surface It may be understood that the communication module 12 for transmitting the information about or the information about the sensor 11) to the user terminal 20. In this case, the functions performed by the detection sensor 11 and the communication module 12 are described in detail with reference to FIGS. 1 and 2, and thus the description thereof will be omitted.

On the other hand, the user terminal 20 may be composed of a communication means 24 and a processor 23, like the block 10 described above.

For example, the communication means 24 of the user terminal 20, in which two blocks approach or contact each other, may be configured to provide at least one of the first block and the second block when the first block and the second block approach or contact within a certain distance. Identification information regarding an area in which the first block and the second block contact, together with identification information of each of the first and second blocks that are accessed or contacted from one (either or both of the blocks in the above example) For example, the contact data including the contact surface or identification information of the detection sensors that detect the contact is received.

The processor 23 performs a step S30 to S40 of FIG. 1 and steps S50 to S80 of FIG. 2 based on the contact data received by the communication means 24. Performs a modeling function by performing a function of.

As such, the embodiment of the present invention may be performed in terms of the system mentioned in the description of FIG. 3, which may be performed in terms of each of the block 10 and the user terminal 20 constituting the system. It will be natural.
