1 is a diagram schematically illustrating a system for providing offline object information using a mobile terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, an offline object information providing system includes a first portable terminal 100, a second portable terminal 200, a mobile communication network 300, and an information server 400. The first portable terminal 100 generates object information, and the second portable terminal 200 requests object information. The second portable terminal 200 may generate additional information related to the object information. The mobile communication network 300 transmits and receives signals between the first and second portable terminals 100 and 200 and the information server 400, and the information server 400 receives and stores object information from the first portable terminal 100. Then, the object information is detected and transmitted to the second portable terminal 200 according to the request of the second portable terminal 200.

The first portable terminal 100 includes a camera module. The user may collect an offline object image, that is, a first object image, and generate object information of the collected first object image through a camera module of the first portable terminal 100. The first portable terminal 100 transmits the first object image and the object information to the information server 400 through the mobile communication network 300.

The second portable terminal 200 may optionally include a camera module, and may collect the second object image for the offline object by using the camera module. The second mobile terminal 200 may request the object information on the second object image by transmitting the collected second object image to the information server 400, and receive the object information from the information server 400. Instead of sending a second object image when requesting object information, a search word may be inputted. In addition, the second portable terminal 200 may generate additional information and transmit it to the information server 400. Additional information is a comment on the object information, whether to recommend the object information.

The information server 400 stores a database of the first object image and the object information transmitted from the first portable terminal 100. In addition, the information server 400 receives and recognizes the second object image from the second portable terminal 200, searches for the first object image corresponding to the second object image, and obtains object information on the first object image. Is transmitted to the second portable terminal 200. The information server 400 preferably transmits only object information in order to increase data transmission speed and reduce usage fee. However, when the request of the second mobile terminal 200 is requested, the information server 400 also corresponds to the first object image corresponding to the second object image. Can transmit

Hereinafter, each configuration of the offline object information providing system will be described in detail with reference to FIG. 2. 2 is a schematic diagram showing an information server 400 according to an embodiment of the present invention.

As shown in FIG. 2, the information server 400 includes an information classifier 410, an information detector 420, an information storage 430, a data transceiver 440, and a server controller 450. do.

The information classifier 410 receives and classifies the first object image and the object information transmitted by the first portable terminal 100. That is, the first object image is transmitted to the information detector 420, and the object information is transmitted to the information storage unit 430. The classification of the first object image and the object information may be based on a data format or a name. The information classifying unit 410 also classifies whether the object information request transmitted from the second portable terminal 200 is a text or an image and transmits the information to the information detecting unit 420.

The information detector 420 extracts a feature point of the received first object image and stores the feature point in the information storage unit 430 as unique identification information of the first object image. For example, the information detector 420 generates a feature map of brightness, color, and directionality of each position of the first object image, and combines the feature maps to form a contrast map for the first object image ( Create a Contrast Map. In addition, the information detector 420 extracts salient points of regions that are remarkably separated, such as an object of the first object image and a background boundary surface, using a wavelet transform, and distributes the salient points. Sets the size and position of the attention window according to the importance in the contrast map. Accordingly, the information detector 420 is an information representing a set of hundreds of protruding points included in the concentrated window area in a unique pattern of an object, and is provided to the information storage unit 430 together with unique identification information (eg, a name). Save it.

In addition, when the object information request transmitted from the second portable terminal 200 is a text format, the information detector 420 checks whether the text is included in the name of the first object image or the object information of the first object image. Meanwhile, when the object information request is the second object image, the information detector 420 extracts a feature point of the second object image and checks whether it matches the first object images stored in the information storage unit 430. As a method of extracting the feature point of the second object image, the method of extracting the feature point of the first object image may be used in the same manner.

The method of recognizing the first and second object images by the information detector 420 is not limited to a method of extracting and recognizing a feature point. In addition, well-known image recognition techniques such as a recognition method using a feature of a component, a recognition method using an Eisen function, and a recognition method using a neural network may be used for object image recognition.

The information detector 420 may detect and transmit the object information and the first object image according to a predetermined condition requested by the second portable terminal 200. For example, when a condition is detected from the most downloaded object information to the object information linked in the top 10, the information detector 420 may detect the corresponding object information and the first object image. However, when the user requests only object information, the information detector 420 detects only the object information requested by the user and transmits the object information to the data transceiver 440.

The information storage unit 430 not only stores the first object image, object information thereof, and feature points of the first object image, but also additional information created and transmitted after viewing the first object image in the second portable terminal 200. Can be stored. In this case, the information storage unit 430 may sequentially store the first object image and the object information according to the download count, update date, and recommendation count. The information storage unit 430 may update the object image and the object information periodically or situationally under the control of the server controller 450. In addition, when the information detector 420 requests specific object information, the information storage unit 430 activates the information and transmits the information to the information detector 420.

The data transceiver 440 receives the object image and the object information from the first portable terminal 100 through the mobile communication network 300 and transmits the object image and the object information to the information classifier 410. In addition, the data transceiver 440 receives the object information request from the second portable terminal 200 and transmits the object information and the first object image to the second portable terminal 200 through the mobile communication network 300.

The server controller 450 controls the overall operation of the information classifier 410, the information detector 420, the information storage 430, and the data transceiver 440 and the signal flow between the components.

3 is a view showing a schematic configuration of a portable terminal according to an embodiment of the present invention. Since the configuration of the second portable terminal 200 can be understood from the description of the configuration of the first portable terminal 100, the following description is based on the first portable terminal 100.

Referring to FIG. 3, the first mobile terminal 100 includes a radio frequency (RF) communication unit 110, a camera module 120, an audio processor 130, an input unit 140, a display unit 150, The storage unit 160 and the control unit 170 are configured to be included.

In addition, the RF communication unit 110 may transmit user data to another terminal, for example, the second portable terminal 200, using a communication channel. In particular, the RF communication unit 110 may transmit the first object image and the object information collected through the camera module 120 to the information server 400.

The camera module 120 may be composed of a lens module and an image sensor module. The lens module includes a light receiving unit that receives light, and the image sensor module converts light incident through the lens module and outputs the digital signal. That is, the image sensor module processes the analog signal incident through the lens module and outputs the digital image data.

The audio processor 130 plays the audio data output from the controller 170 or transmits audio data such as a voice input from a microphone (not shown) to the controller 170. In particular, the audio processor 130 may transmit audio data, which is input as a microphone, to the controller 170 when the user captures a video through the camera module 120. In addition, when a voice signal of the user is input in the object information creation menu, the input voice signal is transmitted to the controller 170.

The input unit 140 includes a plurality of input keys and function keys for receiving numeric or character information and setting various functions. The function keys may include direction keys, side keys, shortcut keys, and the like, which are set to perform a specific function. In addition, the input unit 140 transmits a key signal input in connection with the function control of the first portable terminal 100 to the control unit 170. In particular, the input unit 140 generates key signals corresponding to letters, numbers, and symbols input by the user when generating object information, and transmits the generated key signals to the controller 170. On the other hand, in the case of the second portable terminal 200, the input unit 240 generates a key signal corresponding to letters, numbers and symbols input when the user requests the object information from the information server 400 or writes additional information. To the control unit 270.

The display unit 150 displays various menu screens of the first portable terminal 100, user data input by the user, function setting information, or various information provided to the user. The display unit 150 may be formed of a liquid crystal display (LCD). When the LCD is formed in the form of a touch screen, the display unit 150 also performs the function of the input unit 140. In particular, the display unit 150 may display still images and videos captured by the camera module 120, and may display object information created by the user through the key input unit 140. Meanwhile, in the case of the second portable terminal 200, the display unit 250 may display the first object image and the object information downloaded from the information server 400.

The storage unit 160 stores user data generated by a user and data transmitted / received during communication, including an application program required for operating a function of the present invention. In addition, the storage 160 may include one or more buffers for temporarily storing user data generated while executing a predetermined application program. The storage unit 160 may largely include a program area and a data area. The data area may store the first object image and the object information collected by the camera module 120. In the case of the second portable terminal 200, the data area may store the first object image and the object information downloaded from the information server 400.

The controller 170 may control the overall operation of the first portable terminal 100 and the signal flow between the internal blocks of the first portable terminal 100, and may include a function of a data processor. The data processor is responsible for processing voice data transmitted from the audio processor 130, numeric / text data input from the user, and data transmitted from the RF communication unit 110. The data processor may include a transmitter configured to encode and modulate a signal transmitted through the RF communicator 110, and a receiver configured to demodulate and decode the received signal.

In particular, the controller 170 transmits the object information related to the first object image and the first object image collected through the camera module 120 to the information server 400 in response to a user request in the camera mode. In addition, when a user makes object information about the first object image and then transmits the information to the information server 400, the controller 170 transmits the first object image and the object information to the information server 400. In the case of the second portable terminal 200, the controller 170 may transmit a second object image or a search word to the information server 400 according to a user request, and receive the first object image and object information corresponding thereto. .

On the other hand, Figure 3 shows a block configuration required for explaining the operation according to an embodiment of the present invention for convenience of description, the present invention is not limited to this configuration. That is, the first portable terminal 100 according to the present invention may further include a digital broadcasting module and / or a portable (wireless) internet module according to the provision form thereof.

As described above, the offline object information providing system using the portable terminal may receive various object information stored in the information server 400 using the portable terminal when the object information for the object on the offline is needed.

Hereinafter, a method of providing object information according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4. 4 is a flowchart illustrating a method of transmitting object information in the first mobile terminal 100 according to an embodiment of the present invention.

When the user requests the first portable terminal 100 in the camera mode, the controller 170 switches the first portable terminal 100 to the camera mode and activates the camera module 120 (S101). When the user selects the shooting menu, the controller 170 activates the camera module 120 in a preview state (S102), and when the first object photographing request is input from the input unit 140, the controller 170 uses the camera module 120. Shooting is performed (S103). For example, when the user sets the camera module 120 in the still image shooting mode, the controller 120 captures and displays a still image, and when the user sets the video capture mode, the controller 120 captures and displays a video. When shooting a video, the shooting may be terminated according to a user's request for termination or insufficient storage space of the first portable terminal 100.

Thereafter, when the user requests to transmit the first object image photographing the first object to the information server 400, the controller 170 detects this (S104) to activate the object information creating program and displays the object information creating field. That is, the controller 170 displays an object information input field through which the user can input object information according to the first object image transmission request. When the user writes the object information in the object information input box as shown in FIG. 7A (S105), the controller 170 checks whether the object information input is completed (S106). Upon checking the completion of the input of the object information, the controller 170 transmits the first object image and the object information to the information server 400 (S107). For example, the user climbs Namsan to take a picture of the Seoul Tower as a still image, and in the object information input field to create a course to climb Namsan easily, a location for taking a good picture of Seoul Tower, a place to see in Seoul Tower, etc. Information server 400 To transmit. Such object information may be more practical information for people who actually climb Namsan or visit Seoul Tower.

When the user requests to store the first object image and the object information, the control unit 170 detects this (S108) and stores the first object image and the object information (S109). Subsequently, when the user requests activation of the first object image, the controller 170 may activate and display the object information together with the first object image.

If it is determined in step S102 that the shooting menu is not, the control unit 170 then checks whether the album menu (S110). If it is confirmed that the album menu, the controller 170 displays a still image and a video stored in the storage 160 (S111). In this case, the displayed still image and video may be an image photographed using the camera module 120, or may be an image received from another terminal or a server. The control unit 170 proceeds to step S104 in accordance with the user request to create the object information for the pre-stored still image and video to transmit to the information server 400. In addition, if it is determined in step S110 that the album menu is not the album menu, the controller 170 performs a corresponding function requested by the user (S112).

5 is a flowchart illustrating a method of receiving object information in a second portable terminal according to an embodiment of the present invention.

Referring to FIG. 5, when a user requests an object information search menu, the control unit 270 displays an object information search menu by executing an object information search program in operation S201. As the user selects a shooting menu (S202), the controller 270 activates the camera module 220. When the user inputs a key for photographing, the control unit 270 collects the second object image of the specific object on the offline by using the camera module 220 (S203) and outputs the second object image to the information server 400. (S204).

Here, the user may request object information according to a predetermined condition. For example, when a user requests object information satisfying at least one condition among object information, most downloaded object information, and most recently updated object information for an image having the highest agreement with the second object image, the information server ( The object information according to a condition set by the user is detected from 400 and transmitted to the second portable terminal 200. In addition, when the user of the second portable terminal 200 requests not only the object information but also the first object image, the user may receive the first object image from the information server 400. Here, the first object image and the second object image may be images captured from different sides of the same object.

When receiving the object information corresponding to the second object image from the information server 400 (S205), the control unit 270 displays the object information (S206). After the user reads the object information, as shown in FIG. 7B, when the user writes additional information such as his or her opinion on the second object image, a comment on the object information, and whether to recommend the object information (S207), the controller 270. Check whether or not to send the created additional information to the information server (400) (S208). When the user requests to send the additional information to the information server 400, the control unit 270 transmits the additional information to the information server 400 (S209).

Then, when the user requests the storage of the object information received from the information server 400, the control unit 270 detects this (S210) and stores the object information (S211). If the user writes additional information, it can be saved along with the object information.

However, if it is determined in step S205 that the object information is not received, the controller 270 checks whether the object information is requested again (S212). That is, when the second object image is not normally transmitted to the information server 400 according to the temporary failure of the network or the load of the information server 400 or the state of the second portable terminal 200, the second object Check whether to resend the video. If the user selects the object information re-request (S213), the controller 270 resends the second object image to the information server 400 accordingly. However, when the object information corresponding to the second object image is not stored in the information server 400, the controller 270 is notified of this and displays it on the display unit 250 to alert the user. Accordingly, the user may request rescanning by photographing a specific object on the offline again.

In addition, if it is determined in step S202 that the object photographing request is not performed, the controller 270 checks whether a search word is input in the search word input box (S214). When a search word is input in the search word input box, the controller 270 transmits the input search word to the information server 400 (S215).

6 is a signal flow diagram illustrating a method for providing object information according to an embodiment of the present invention.

Referring to FIG. 6, the first mobile terminal 100 collects a first object image according to an offline object through the camera module 120 (S301), and creates object information related to the first object image (S302). . The first portable terminal 100 transmits the first object image and the object information to the information server 400 (S303).

The information server 400 stores the first object image and the object information transmitted from the first portable terminal 100 (S304). Thereafter, when the information server 400 receives the object information request from the second portable terminal 200 (S305), the information server 400 detects object information corresponding thereto (S306). For example, when the information server 400 receives the information request for the second object image from the second portable terminal 200, the first object image having the feature points corresponding to the extracted feature points is extracted by extracting the feature points of the second object image. Make sure it is saved. When there is a matching object image, the information server 400 detects object information according to the matched object image and transmits it to the second portable terminal 200 (S307). Here, when the first object image that matches the feature point of the second object image does not exist, the information server 400 may detect an object image with high similarity and transmit the same to the second portable terminal 200. This similarity level can be set by the user.
