Description

Providing System of Position Path and Shooting Information

The present invention relates to a system for providing a terminal with moving path information and camera photographing information of an elderly person or a child.

Location Based Service (LBS) is used to provide location information based systems and services by utilizing mobile communication networks such as mobile phones and PDAs and IT technologies. This service is based on customer location information. It is used for not only product information but also traffic information and location tracking information.

However, in the location-based service, as well as traffic-related information services such as driving information, route search and setting of public transportation information, location tracking information services such as location tracking, personal location information, and lost terminal tracking are possible. In addition, the information on the convenience of life, such as logistics, services of convenience, telephone number service, local information, and the like, as the commerce information can provide services such as notification function for the desired product, location-based marketing / advertising.

By the way. Location-based service methods include Cell and GPS.

The Cell method uses a mobile communication base station to determine the user's location in the 500-1500m error range around the base station connected to the subscriber, and calculates the location based on the location of all base stations that are referenced or referenced. do.

However, the Cell method has a disadvantage that only the approximate location can be determined due to the wide range of error, and the advantage of finding the location even in areas where GPS signals are not received, such as in the building and underground, In the environment, when finding a location, there is a problem that the error may increase rapidly and may reach several tens of Km.

On the other hand, GPS method can track location more precisely than Cell method. It can find the exact location within 10-150m error by receiving satellite signal from GPS chip, but it is periodically and continuously positioning due to high cost and power consumption. It is difficult to use in the city, and due to the characteristics of satellite signals, it cannot be used indoors, and because of the good reflection and refraction by buildings, it is vulnerable to high-rise buildings and requires the use of expensive GPS chips.

In addition, the mobile communication company's location-based services use the Cell method and the GPS method together. As described above, the Cell-based positioning is too large and the GPS method cannot be continuously made due to the high cost and power consumption. There is a problem that cannot be used for querying the location information and movement trajectory of the past time, in particular, the positioning itself is impossible when the mobile terminal is turned off.

On the other hand, a service that derives the current location of the elderly or the child and notifies the guardian's terminal to the address or displays it on the map is used, but it only notifies the final location information, where the child went and what It does not provide information about what you were doing.

In addition, there is a service that provides a real-time video shot using a camera installed in a limited area within the apartment complex, but in this service, parents can find surveillance cameras installed in various parts of the complex to find out where their children are located. Using the PC, etc.), you can find the position of your child by looking at the image visually. If the number of cameras is large, it takes a lot of time and it is difficult to distinguish whether the child is a photographed image. Lack of installation position is bound to limit the scope of observation of the child.

In particular, if a child is missing, abducted or injured, the current location information or photographed image indicates the current location of the child or the image of the child, but at which point It is not possible to determine whether an accident occurred in the city, so it is not possible to determine the cause of the accident, the movement route and the situation during disappearance and abduction, and it is often difficult to estimate the criminal's escape after the abduction.

SUMMARY OF THE INVENTION In view of the above-described problems, the present invention provides a system for providing position trajectory information of a subject (eg, a child) and photographing information at each position.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an overall configuration diagram of the present invention.

According to the present invention, a photographing unit (1) equipped with a camera for photographing an image is installed at a plurality of points, and the child has user identification information (IDu) and has a sending unit (2) for periodically transmitting a recognition signal. Each photographing section 1 is provided with a receiving section 3 for receiving the identification information (IDu) signals of the sending sections 2, respectively, and the destination identification information IDr is assigned to each of the receiving sections 3, respectively. It is. At this time, the sensitivity of the receiver 3 should be appropriately adjusted so that only the transmitter 2 within a specific distance (nearby) is detected.

In addition, by adjusting the reception angle of the antenna of the receiver 3 to recognize the direction angle information of the transmitter 2, whether or not the user is photographed and position accuracy may be increased.

In addition, the user identification information IDu received at each receiving section 3, together with the destination identification information IDr of the receiving section 3, is periodically transmitted to and stored in the remote location storage section 4, In the location storage unit 4, the user identification information IDu is received for each user identification information IDu through a time T at which the user identification information IDu is received, the recognized user identification information IDu, and the destination identification information IDr. The recognized time T and the destination recognition information IDr are classified and stored in the same manner as in FIG. 2, so that the user can move the position trajectory.

In this case, since it is difficult to install an expensive camera for each of the receivers 3, it is also possible to install a stand-alone receiver 3 that is not associated with a camera in a building.

In addition, as shown in Fig. 3, instead of the passive receiving unit that simply receives the input signal, the active receiving unit 3 is used, for example, the active receiving unit 3 is installed at the main entrance to recognize the door opening and closing operation. When the active receiver 3 transmits the location information request signal, the transmitters 2 near the door receive the request signal and transmit their own user identification information IDu, and the active receiver 3 It is also possible to receive the user recognition information IDu and store it in the location storage unit 4.

In this way, if a single receiver 3 is installed in the building, an active receiver 3 is installed at the door, and a receiver 3 connected to the camera is installed outside the building, the guardian of the child (user) leaves the house and goes back to work. It is possible to easily grasp the entire movement position trajectory until returning home.

In addition, the image storage unit 5 stores in advance the photographing unit separator IDc for distinguishing each photographing unit 1 and the position information of the photographing unit separator IDc, which are photographed by each photographing unit 1. When the captured image is transmitted to the remote image storage unit 5, the image storage unit 5 stores the captured image along with the capturing time for each of the capturing unit IDc as shown in FIG.

In this case, when the camera installed in the photographing unit 1 is an analog camera, an amplifier for amplifying the analog signal output from the camera in the middle and transmitting the image signal to the image storage unit 5 exists, and the image storage unit 5 is present. On the side, there is an image converter for sampling the analog image amplified and transmitted by the plurality of photographing unit 1, converts the analog image into a digital signal, and sequentially transmits the analog image to the image storage unit 5.

In addition, when the camera installed in the photographing unit 1 is a digital network camera, the analog image is converted into digital in the network camera, and the converted digital image signal is directly transferred to the image storing unit 5 through the Internet. Will be sent.

In this way, the image storage unit 5 stores the images photographed at each time T in each photographing unit 1 in the same manner as in FIG. 4.

In addition, the inquiry unit 6 is a wall PAD installed on a wall of the house, a PC, or a mobile terminal, and when the child's position trajectory information and photographed image information are requested through the inquiry unit 6, the position storage unit 4 is provided. The child's transmitter 2 receives visually the location trajectory through the detected hourly location information, and sees the time-related photographed image received by the image storage unit 5.

Now, the operation of the system of the present invention having the configuration as shown in FIG. 1 will be described in detail.

The transmitter 2 worn by the child periodically transmits user identification information IDu.

Each receiving unit 3 receives user identification information IDu1, IDu2 .... transmitted from a plurality of transmitting units 2 present in the periphery, and stores the location storing unit 4 together with the destination recognition information IDr. ), The location storage unit 4 stores the reception time T and the destination recognition information IDr for each user identification information IDu in the format as shown in FIG. It is possible to provide location trajectory information by recording whether or not it is present in the.

In addition, each photographing unit 2 photographs the surroundings and periodically transmits the photographing unit identifier IDc to the image storage unit 5 together with the photographing time zone by the photographing unit identifier IDc in the same manner as in FIG. 4. The captured image is saved.

Now, when a parent is curious about a child's sympathy or after an accident has occurred, the parent (guardian) wants to know what path the child has traveled by time of day and what he did at each location (what was the situation). The method of acquiring the position trajectory information and the photographing information in the inquiry section 6 will be briefly described.

First, the parent selects the position trajectory information and the photographing information menu in the inquiry section 6.

Then, the inquiry unit 6 transmits the user identification information IDu of the calling unit 2 owned by the child (pre-inputted in the inquiry unit 6) to the position storage unit 4, and the position storage unit In (4), when the time T1, T2 ... Tn and the destination recognition information IDr1, IDr2 ... IDrm which exist the user recognition information IDu are derived and transmitted to the inquiry part 6, inquiry is made. In the section 6, the position of each child is identified by the destination recognition information IDr corresponding to each time T, and displayed on a map on the screen, so that the movement trajectory of the child is displayed.

In addition, the location storage unit 4 displays the time (T1, T2 ... Tn) and the destination recognition information (IDr1, IDr2 ... IDrm) of the child's location is detected along with the user identification information (IDu), If it transmits to the storage unit 5, the image storage unit 5 searches for whether there is a related image through the times (T1, T2 ... Tn) and the destination recognition information (IDr1, IDr2 ... IDrm). The corresponding captured image is transmitted to the inquiry section 6 corresponding to the user recognition information IDu.

Then, the inquiry unit 6 sequentially displays the images photographed at the times T1, T2, ... Tn where the position of the child is detected on the screen.

Through the above process, when the position trajectory information and the photographing information corresponding to the receiving unit 3 detecting the transmitting unit 2 possessed by the child are transmitted to the inquiry unit 6, the parent can easily move the child. The path can be identified, and the child's situation can be easily identified while watching the image recorded on the moving path.

In addition, when the transmitter 2 transmits the user identification information IDu, the receiver 3 uses a method of detecting the IDu, so that accurate location tracking is possible as compared with the conventional technology using the cell-based mobile communication base station. In addition, compared to the prior art based on GPS using an expensive GPS chip, it is possible to accurately and accurately track the location.

Next, the overall process for using the present invention will be described with reference to FIG.

First, the guardian is connected to the server that manages the location storage unit 4 and inputs his own account information (ID, password, address, contact, etc.) to be given permission to use. At this time, this process is omitted in the inquiry unit 6 such as Wall PAD, to which the use right is granted in advance.

Now, the guardian requests the server for the location storage unit 4 for the location lookup service of the child through a terminal such as a wall PAD or a PC, a mobile communication terminal (S1).

The server checks whether it is a request from a terminal having a location inquiry authority, if there is no authority, guides the reason through the terminal and terminates, and if there is authority, proceeds to the next step (S2).

The server retrieves the location trajectory information of the child from the location storage unit 6 (S3).

Now, the complete position trajectory information is provided to the terminal to display the movement position trajectory on the terminal screen (S4). In this case, the determined time information of the user staying for each receiving unit 3, the presence of the image information, and may provide information (address, etc.) for the other person having the sender at the same time / same location.

Then, the server determines whether an image corresponding to the position information exists in the image storage unit 5 (S5).

If there is image information, first, a brief information about the time the child stayed within the operation range of each photographing unit 1 is transmitted to the terminal for display (S6).

When the guardian sees this brief information and selects video information inquiry on the terminal (S7), the server transmits the determined time T and the photographing unit separator IDc to the image storage unit 5 to request image information provision. (S8), the photographed image corresponding to the time T determined in accordance with the request and the photographing unit separator IDc is derived and transmitted to the terminal for playback (S9). At this time, it is preferable to optimize the image information provided in consideration of the specifications of the terminal and to transmit to the terminal.

Although one preferred embodiment of the present invention has been described above, the present invention is not limited to this embodiment, but various modifications can be made without departing from the principles of the present invention.

For example, suppose that one sender 2 corresponds to one query unit 6, and if the parent selects the position trajectory information and the shooting information menu from the query unit 6, the query unit Although one user identification information (IDu) already stored in (6) has been described as being transmitted to the location storage unit 4, but there are many children, one inquiry unit is used when multiple transmitters 2 are used. (6) stores the user identification information (IDu) for the plurality of transmitters (2), and if the parent wants to receive the location trajectory and the captured image of the specific child, the parent to select the specific user identification information (IDu) Then, the inquiry unit 6 receives the position trajectory and the captured image corresponding to the specific user recognition information IDu from the position storage unit 4 and the image storage unit 5 and displays them on the screen of the inquiry unit 6. It is also possible to make it.
