Description

  The present invention relates to a network connection method, a network connection system, a management server, and a mobile phone using a reference image having a displayed shape, for example.

  In recent years, barcodes composed of various thickness lines are displayed on most products distributed in the market to indicate product information such as product type and price. Such a bar code is composed of a thick line, a thin line, a double line, etc., and indicates numeric data in which product information is encoded.

  On the other hand, a network address such as a URL (Uniform Resource Location) such as a company Internet homepage address or an e-mail address may be displayed on a business card for general business purposes.

  Such Internet homepages contain information about the company's publicity, and Internet users interested in the company can read the company's publicity on the Internet homepage and then send an e-mail address when there is an inquiry. Try to contact In addition to business cards, Internet homepage addresses and URLs of specific companies may be displayed in advertisement fields such as magazines and newspapers.

  At this time, in order for a user to connect to the URL displayed on these media, the URL displayed on the media must be typed with the keyboard. Or, if an e-mail address is displayed on these media, a user who wants to send an e-mail to the e-mail address must type all the e-mail addresses.

  However, Internet homepage addresses or e-mail addresses are not composed of one or two characters, but are generally composed of ten to several cross characters. As a result, it is difficult for the user to input the address, and there is a problem that the network address is erroneously input and a predetermined service is not provided.

  As a conventional technique for solving such a problem, information relating to a network (for example, addresses and URLs on a specific network, characters and symbols contained in a URL, etc.) is coded using colors and shades according to an already defined code system. An image (color code) is converted and displayed on a predetermined medium, and the user acquires the code image by a PC camera, a digital camera, a scanner, or the like, and the user's computer uses a predetermined code system based on the code system described above. There is one that decodes a network address or URL and receives a service of a connected network based on the decoding information (see, for example, Patent Document 1).

However, in the above prior art, it is necessary to set a code image corresponding to information about the network, which may cause a problem that the number of processes increases due to network connection.

  According to a network connection method, a network connection system, a management server, and a mobile phone according to an aspect of the present invention, a user's computer can be easily connected to a desired network address.

  A network connection system according to an embodiment of the present invention is for connecting a user's computer to a predetermined network address through a network (communication network).

  In the embodiment of the present invention, for example, a reference image displayed on a paper surface, a television screen or the like is photographed with a mobile phone (user terminal), and the photographed image data is transmitted to the management server. A system is proposed in which the mobile phone can be connected to mobile content related to the reference image via the network based on the data returned from the management server in response to the transmission of.

  That is, the user (recipient) can display a reference image in a state displayed on a screen (for example, a television screen or a personal computer monitor), a state printed on a predetermined medium such as a business card, or a state that can be input by an optical device. When it is distributed and it is going to receive a network service, the reference image is input to a computer (mobile phone) (image data is acquired).

  And a user transmits the data of the image | photographed image to the management server.

  Then, the user connects to a desired network address using the target data including the network address returned from the management server in response to the transmission of the data, and is provided with a network service.

  Here, the reference image is displayed in a physical form that can be input through an optical device or in an electronic form such as an image file that can be read by a computer.

  This reference image is in a form that can be seen visually, or exists in the form of an electronic file, in which a shape (including characters such as a company name and logo), a combination of shape and color, pattern, etc. are used. It is expressed.

  On the other hand, a reference image input by an optical device and designed by a program is stored in a memory (disk, buffer, screen) of a computer (for example, built in a mobile phone).

  An optical device (image acquisition device) is a device that can acquire visual information using light, and corresponds to a digital camera (for example, attached to a mobile phone), a PC camera, a scanner, or the like.

  Hereinafter, embodiments according to the present invention will be described in more detail with reference to the drawings.

  Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a network service system according to a first embodiment of the present invention.

  A network connection system 100 according to the present invention includes a management server 1, a service server 2 that provides a network service, and a user image acquisition device that can capture an image 4 including a reference image 4a and acquire image data of the image. And a user terminal 5 having a user computer connectable to the management server 1 and the service server 2 via a network (communication network) 3.

  The management server 1 can store network address information related to the service server 2 and can further store index information defined for the address information. Here, the network address indicates the position of the specific equipment in the network environment and is indicated by letters, numbers, special characters, URL, IP (Internet Protocol) address, telephone number or unique identification number of the wired / wireless communication terminal. It is.

  Further, the management server 1 analyzes the reference image 4a and the table 1a in which the target data including the network address related to at least the service server 2 is associated with the shape of the reference image 4a, and recognizes the shape of the reference image 4a. A recognition algorithm.

  Then, the management server 1 recognizes the shape of the reference image 4a using the plurality of image recognition algorithms.

  For example, the management server 1 analyzes the shape of the reference image 4a simultaneously in parallel using a plurality of image recognition algorithms having different analysis methods such as a statistical approach and a syntax analysis approach described later, and based on the analysis result. The shape of the reference image 4a is recognized.

  Here, dozens of algorithm design approaches exist in the fields of computer vision and shape (pattern) recognition. In each analysis method, the simplification of assumptions is different, which greatly affects the behavior of the image recognition algorithm and the synthesis application to a specific image class.

  For example, a statistical approach that uses mathematical facts to capture the whole image can give good results with magazine advertising images, but with a simple logo design it is difficult to get the desired results.

  On the other hand, a parsing approach that adapts to the final set of derived elements has the opposite feature of a statistical approach.

  Therefore, by using a plurality of image recognition algorithms having different analysis methods such as a statistical approach and a syntax analysis approach, it is possible to obtain high extensibility with respect to a narrow range of the simple reference image 4a.

  The management server analyzes and recognizes the shape of the reference image 4a using one image recognition algorithm. If the management server cannot recognize the shape, the management server analyzes and recognizes it using an image recognition algorithm of another analysis method. Also good.

  The table 1a is created by associating the target data with the shape of the reference image 4a, but may be associated with the target data including the color of the reference image 4a in addition to the shape of the reference image 4a. As a result, the amount of information that can be associated with the table 1 increases.

  The target data of the table 1a can include a name, protocol, document name, service information, etc. as required by the user in addition to the network address described above.

  If necessary, the management server 1 replaces the target data including the network address with the target data including the other network address, associates it with the shape of the reference image 4a, and changes the contents of the table 1a. In other words, the management server 1 is not limited to the range in which the target data is defined as in the conventional two-dimensional code, but can be made to correspond to the reference image 4a, for example, in response to a request from a user or a service provider. You can change the data.

  The service server 2 provides, for example, service information to the user terminal device 5 connected using the target data.

  As the service information, when an Internet service is used, there are services defined by a protocol displayed in a URL such as a web service, a telnet service, an e-mail service, a gopher service, and FTP (File Transfer Protocol). .

  In addition, users can not only connect directly to specific services provided on each server, such as online education services and shopping mall services, but also use text, picture files, or audio provided by specific IP addresses and URLs. Multimedia information composed of stop images and moving images can be provided.

  On the other hand, the service information includes services defined for other general communication devices, for example, for telephone and FAX services, in addition to those for network services through the Internet. For example, when a telephone number or a FAX number is included as the address information, a service for making a call to the number or sending a FAX is provided to the user.

  Further, as described above, since the management server 1 can change the target data associated with the reference image 4a in response to a request from the user or the service provider, the service server 2 can change the changed purpose data. A network service corresponding to data can be provided.

  The user terminal 5 is, for example, a mobile phone, a computer, a PDA (Personal Digital Assistant), a smart phone, or an IMT (International Mobile Telecommunication) -2000 terminal.

  For example, when the user terminal 5 is a mobile phone, the data or file of the image 4 including the reference image 4a acquired from a paper surface, a TV screen, etc. through an image acquisition device such as a digital camera provided in the mobile phone. The reference image 4a is input and stored in a memory, a disk, a buffer or the like of a computer built in the mobile phone.

  The user terminal 5 can obtain the target data from the management server 1 by transmitting the data of the image 4 including the input reference image 4 a to the management server 1.

  In the management server 1 of the network connection system 100 having the above configuration, as described above, in the process of recognizing the shape of the reference image 4a, a process of searching for the shape, color (color), etc. of the reference image 4a is necessary. It is. In addition, a process for correcting a distorted image is required. They can detect shapes and patterns using image recognition algorithms such as boundary detection and thinning algorithms, for example.

  Also, use one or more methods in RGB (Red, Green, Blue) model, HSV (Hueangle, Saturation, Value) model, CMY (Cyan, Magenta, Yellow) model, HLS (Hueangle, Lightness, Saturation) model Thus, color discrimination is possible.

  Recognition of a shape (pattern) by an image recognition algorithm of a computer is a process of making an observed shape correspond to one of predetermined concepts (classes).

  For example, in the case of recognizing a number, the processing is to make a given image (shape) correspond to any of 0 to 9.

  Pattern recognition by an image recognition algorithm is usually performed in two processes, feature extraction and identification.

  Feature extraction is a process of extracting information from which an object can be distinguished from an observation pattern. All information is quantified to make it easier for computers to handle. The extracted information is called a feature. What features are extracted is an important factor that determines the performance of shape (pattern) recognition.

  Identification is processing for determining which class an observed shape (pattern) belongs to using the obtained features. Since the numerical value obtained from the observed shape is an object, the theory of identification can be applied to various recognition objects.

  Discrimination methods using image recognition algorithms can be broadly classified into statistical approaches and syntactic approaches.

  In the statistical approach, a large amount of data is collected in advance for each class to be recognized. Based on the statistics (average, variance, etc.) obtained from the collected data, the likelihood that the observation pattern belongs to each class is evaluated. As a general method capable of dealing with various features, there is a method of considering a probability distribution. A feature is obtained by collecting a lot of data for each class, and a probability distribution of the feature is obtained. A feature is obtained from an unknown observation pattern, and the probability that it belongs to each class is calculated. This is a method of determining that the class with the highest probability is the most likely class.

  On the other hand, in the parsing approach, each class pattern is considered to be generated according to a certain rule (grammar), and the class is determined by determining which class rule generates the observation pattern.

  Next, an example of the reference image 4a used in the network connection system 100 as described above will be described.

  FIG. 2 is a diagram illustrating an example of a reference image used in the network connection system according to the first embodiment.

  As shown in FIG. 2, the reference image 4a is not limited to a two-dimensional code or the like, and various image images (here, the shape of a personal computer monitor) are targeted. In FIG. 2, the reference image 4a is expressed in monochrome, but the reference image 4a may have a color.

  Next, the flow of the network connection method of the network connection system 100 shown in FIG. 1 will be described.

  FIG. 3 is a flowchart of a network connection method for connecting a computer of a mobile phone (user terminal) to a predetermined network address through a network.

  As shown in FIG. 3, first, an image 4 including the reference image 4a in which a table 1a in which target data including at least a network address is associated with the shape of the reference image 4a is created is displayed on the user's image acquisition device ( Obtained by a digital camera provided in the mobile phone (step S31).

  Next, the user's computer (built in the mobile phone) transmits the image data of the image 4 acquired by the image acquisition device to the management server 1 connected via the network 3 (step S32).

  Next, the management server 1 recognizes the shape of the reference image 4a from the received image data using an image recognition algorithm, and searches for target data corresponding to the recognized shape using the table 1a (step S33). . As described above, for example, the management server 1 analyzes the shape of the reference image 4a simultaneously in parallel using a plurality of image recognition algorithms having different analysis methods such as a statistical approach and a syntactic approach described later, Based on the analysis result, the shape of the reference image 4a is recognized. In addition, as described above, the management server 1 analyzes and recognizes the shape of the reference image 4a using one image recognition algorithm, and if it cannot be recognized, analyzes using the image recognition algorithm of another analysis method. May be recognized.

  Next, the management server 1 transmits the searched target data to the user's computer via the network 3 (step S34).

  Next, the user's computer connects to the network address included in the received target data through the network 3 (step 35).

  Then, the network service is provided from the predetermined service server 2 with the network address to the user's computer (step S36).

  With the above flow, a user's computer is connected to the service server 2 via the network 3, and a desired network service is provided from the service server 2 to the mobile phone 5.

  As described above, the management server 1 changes the target data associated with the reference image 4a in response to a request from the user or the service provider, so that the service server 2 changes the target data to the changed target data. Corresponding network services can be provided.

  As described above, according to the network connection method, the network connection system, the management server, and the mobile phone according to the present embodiment, the user's computer can be easily connected to a desired network address.
