Description

  The present invention relates to a method for easily registering an image taken with a portable information terminal using a portable information terminal into an equipment location information management system.

  Conventionally, as a method for capturing images of utility poles, power lines, communication cables, etc. into the equipment location information management system, photographs taken with a digital camera are stored in a storage medium and registered in the system after returning to the office. However, this method is inefficient because it is necessary to take a photo again on the spot when there is a deficiency in taking a photo or when it is missing.

  There exists patent document 1 as a technique which solves such a thing. This document discloses a method of registering in a system while on the spot by sending a photograph taken with a portable information terminal by e-mail to the facility information management system together with an individual identification number of the facility.

JP 2006-134119 A

  However, in the technique of Patent Document 1, since the photograph taken with the portable information terminal is transmitted together with the individual identification number of the equipment, the equipment ID must be input accurately. For this reason, there have been registration failures due to an individual identification number that has been input incorrectly, and errors that result in registration to another facility. As described above, it is a problem to input a complicated equipment ID when an image captured using a portable information terminal is registered in the system by mail transmission.

  In the present invention, a portable information terminal having a GPS receiver and a communication function connectable to the facility management system is used. The photographer transmits the equipment photo with the GPS information added thereto to the equipment location information management system. The equipment location information management system transmits the nearest equipment list to the photographer's mobile terminal based on the GPS information added to the received photograph. The photographer selects which equipment is the photograph taken from the equipment list displayed on the portable terminal, and registers the image in the equipment management system. Thereby, a more accurate extraction result can be obtained.

  ADVANTAGE OF THE INVENTION According to this invention, when registering an image using a portable information terminal in an equipment position information system, the registration failure by the input mistake of equipment ID and the mistake which registers to another equipment can be reduced.

  FIG. 1 is a schematic diagram illustrating an example of the configuration of a facility location information management system to which the present invention is applied. In FIG. 1, the equipment location information management system has a portable information terminal 20 that can communicate with a geographic information system 10 via the Internet.

  The geographic information system includes an equipment location information database 104 that records latitude and longitude information as equipment location information, an equipment attribute information database 105 that records information such as equipment ID numbers, types, and shapes, and latitude and longitude information from GPS information. It has a GPS information analysis unit 101 to acquire, a direction information analysis unit 103 that analyzes direction information, and a transmission / reception unit 102 that transmits and receives image information, facility information, and the like via the Internet.

  The portable information terminal has a camera function 203 that captures an image of equipment, a GPS function 201 that acquires GPS information, a display 204 that displays a captured image and a screen of an equipment image registration application described later, and an equipment image displayed on the display. A keypad 205 for operating buttons and the like on the screen of the registration application, and a transmission / reception unit 202 for transmitting and receiving image information, facility information, and the like, and a facility image registration application 206 for linking them are installed.

<Operation of the present invention>
The present invention operates in the following form.

  FIG. 2 is a process flow of the photographer of the facility. First, the photographer activates an equipment image registration application (S201). Thereby, the short information terminal is connected to the geographic information system, and the image registration screen (FIG. 3) is displayed. Next, the “shoot” button on the image registration screen is pressed to activate the camera function (S202). Next, the photographer takes a picture of the target equipment (S203). At this time, GPS information of the shooting location is added to the photograph using the GPS function. After taking the picture, the photographer arbitrarily selects the type of equipment and the number of displayed pictures and presses the “Search” button (S205). By pressing the search button, a search request is transmitted from the portable information terminal to the geographic information system. The GPS information analysis unit of the geographic information system extracts GPS information included in the received search request. The search unit searches the equipment location information database based on the extracted GPS information, thereby extracting equipment (equipment ID) close to the photographer. The GPS information analyzer then calculates the distance between each facility and the photographer based on the GPS information. Next, the list creation unit identifies the type of each extracted facility from the extracted facility ID and facility attribute information database, and combines the distance from the shooting location extracted earlier and the facility ID to the portable information terminal. Create equipment list information to be sent. The geographic information system transmits the equipment list information (equipment ID, type of equipment, distance from the shooting location) extracted to the portable information terminal via the network. As a result, the portable information terminal can obtain a list of facilities that are close to the shooting location, and can select an appropriate facility from the list to register an image in the geographic information system (FIG. 4). . Here, the display on the portable information terminal is sorted in the order of the shortest distance from the shooting location, and the number of cases designated by the portable information terminal is displayed. Note that the distance from the shooting location included in the facility information transmitted to the portable information terminal is calculated by taking the difference between the GPS information added to the photograph and the information in the facility location information database.

If the information displayed on the portable information terminal includes information about the equipment photographed by the photographer, the equipment is determined by pressing the option button for the corresponding location (S209). The information thus determined is transmitted to the geographic information system via the network.

  If there is no corresponding equipment in the equipment list information sent from the geographic information system, or if it is difficult to find, it is determined whether to transit to the list on the second page or to correct the search result (S210). . When searching for equipment in this search result without correcting the search result, press the “Next” button to move to the next page, obtain the next equipment list information, and display the relevant equipment. The search is performed until it is completed (S211). When the search result correction is performed, the process returns to S204 and the search result correction is performed.

  Here, there are the following two methods as a search result correction method. The first is a method of transmitting the direction taken using the electronic compass function to the geographic information system. By this method, the search result of the equipment behind the photographer is not displayed. The electronic compass function is activated by pressing the “Register Direction” button on the image registration screen. The second is a method of retransmitting GPS information to the geographic information system after the photographer is closer to the target facility than the shooting location. Usually, when an image of the facility is captured, since the location is several meters away from the facility, a position shifted from the actual location of the facility is added as GPS information. For this reason, by retransmitting the GPS information after approaching the equipment, it is possible to correct the deviation between the photographing position and the actual equipment. The GPS information reacquisition function is activated by pressing the “GPS reacquisition” button on the image registration screen. Using these two search result corrections as appropriate, the photographed facility image is registered in the geographic information system.

  In the above description, only the search button is displayed when passing through S204 for the first time, and other menus (direction registration, GPS reacquisition) are also displayed when returning to S204 to correct the search result. Explained the example. However, it is also possible to display all menus from the first time through S204.

  FIG. 5 is a flow of the facility list information search process of the geographic information system. After the file name of the image with GPS information is input on the image registration screen, the process branches to the following three processes by a button pressed by the photographer. When the “Search” button is pressed, the latitude / longitude information of the shooting location is extracted from the image with GPS information by the GPS analysis unit. Several pieces of equipment list information are acquired from the equipment location information database in the order from the shooting location. The number acquired at this time is the number of display items selected by the portable information terminal. When the “Register direction” button is pressed and direction information is input, the process of extracting the latitude and longitude information of the shooting location from the GPS analysis image from the image with GPS information is the same as when the “Search” button is pressed. Together, the target equipment list information is acquired from the equipment attribute information database for the number of displays after targeting the equipment in the direction of −90 degrees to +90 degrees in the input direction. When GPS information is input by pressing the “Re-acquire GPS” button, latitude and longitude information is extracted from the input GPS information by the GPS analysis unit, and the nearest equipment list is displayed for the number of items displayed based on this latitude and longitude information. get. Any one of the “Search”, “Direction registration”, and “GPS reacquisition” buttons is pressed to acquire the equipment list information, and then the equipment list display screen reflecting the acquired equipment list information is displayed on the portable information terminal. After the display, when the corresponding equipment is selected from the equipment list display screen by the photographer and the “Register” button is pressed, the image is registered in the equipment attribute information database, and the process is terminated. When the “Next” button is pressed from the equipment list information screen, the nearest equipment list information is acquired from the equipment attribute information database by the number of display items and transmitted to the portable information terminal.
