The pipe installation work site including the unit 4 is photographed, or the flight is performed immediately above the pipe installation work site including the measurement point and the base point, and the imaging device 33 is controlled to photograph the pipe installation construction site.

  The image captured by the imaging device 33 and the position information measured at predetermined time intervals by the GPS positioning device 32 and monitor image displayed on the display screen of the information processing terminal 110. The operator visually observes the image displayed on the monitor, and operates the image capturing switch provided on the operation screen to capture the imaging information at that time as a still image when judging that the image capturing position reached an appropriate imaging position.

  While imaging information to be a still image is captured by the imaging device 33 in synchronization with the switch operation, position information (latitude, longitude, altitude) of the flying object 130 positioned by the GPS positioning device 32 at that point is captured. Further, posture information of the imaging device 33 at that time is fetched and stored in the memory, and thereafter, the imaging information, the position information and the posture information are read from the memory and transmitted to the information processing terminal 110. Information indicating imaging conditions such as imaging magnification (focal length), level, time, etc. is added to the imaging information.

  For example, it is possible to associate each piece of imaging information with a joint number that identifies a pipe joint. Further, the time when the image capture switch is operated on the information processing terminal 110 is attached to the joint number as a time stamp, and the association can be made by collating with the time stamp attached to the imaging information by the imaging device 33 May be

  Moreover, if it is imaging information including a station, it is possible to associate with a management number unique to the piping installation including the station, and the flying object at the time of shooting determined by the GPS positioning device 32 provided in the flying object 130 It is possible to associate imaging information for each station from the position information and the position information of the station measured by the GPS positioning unit 15 provided in the information processing terminal 110. For example, if it is defined that the lower right from the approximately vertical upper position of the measurement point be defined, the latitude and the longitude become almost the same value, so each imaging depends on whether or not the latitude and the longitude exist within a predetermined threshold. Information can be associated with the plumbing equipment that will be the station.

  The information processing terminal 110 transmits the above-mentioned pipe information, pipe installation information, and connection relation information to the information processing server 120 as pipe construction diagram basic information each time the pipe is joined or every time a facility serving as a measurement point is laid. While transmitting, the imaging information, the position information, and the attitude information received from the aircraft 130 are configured to be transmitted to the information processing server 120.

  The mapping processing unit 21 of the information processing server 120 that operates according to the operation input to the operation terminal device stores the piping construction diagram basic information and the imaging information, the position information, and the posture information transmitted from the information processing terminal 110 in the storage unit The piping construction diagram generation unit 23 is activated. The piping construction drawing generation unit 23 is a functional block that generates a piping construction drawing showing a relative connection relation in plan view of each installation target pipe by the information processing apparatus based on the pipe shape, the pipe installation information, and the connection relation information. is there.

  The piping construction diagram generation unit 23 automatically generates a diagram as shown in FIG. 3 as a piping construction diagram and stores it in the storage unit, and transmits it to the information processing terminal 110 via the communication processing units 27 and 17. Is configured.

  This will be described specifically. In the piping construction drawing, since the positional information of the joint does not matter, the joint of the first pipe is set at an arbitrary position of the drawing layer, and the shape and length of the pipe obtained from the pipe information starting from the joint; A process of drawing a line corresponding to a length in plan view of a pipe based on pipe installation information obtained from pipe installation information, that is, information such as where the pipe bends and to which branch it is an information processing terminal It is repeated each time piping construction information is transmitted from 110. For example, when the curved pipe is vertically bent, it is converted to a length in plan view and drawn. With such a piping construction diagram, it is possible to grasp how the pipes are laid, and the relative joining relationship between the pipes.

  The piping construction diagram generation unit 23 is also configured to automatically generate a construction daily report and store it in the storage unit, and to transmit the construction daily report to the information processing terminal 110 via the communication processing units 27 and 17.

  A daily work report is illustrated in FIG. The daily work report has the following fields: construction name, construction site, identification name of each contractor, date and time when construction was carried out, weather, process, volume extension, total materials used, material details used, residual pipes, etc. It is a slip in which construction management information including pipe information is indicated in each item column.

  The piping construction drawing and the construction daily report are updated each time piping construction drawing basic information including the above-mentioned pipe information, pipe installation information, and connection relation information is transmitted from the information processing terminal 110, and the result is subjected to information processing. It is transmitted to the terminal 110.

  The piping construction diagram display unit 14 provided in the information processing terminal 110 is a functional block that displays them on the touch panel 14a each time the piping construction diagram and the construction daily report are transmitted from the information processing server 120.

  The pipe information is acquired via the pipe information acquisition unit 11 either before or after at least the pipe joint processing at the construction site, and the direction of the installation target pipe and / or the joint object via the pipe installation information input unit 12 The pipe installation information including the joining order of the mouth is input, and the joining relation information is generated through the joining relation information generation unit 13.

  The pipe installation information input unit 12 is provided with a pipe end type input unit for displaying an input screen for inputting at least the type of the welding target pipe end of the installation target pipe. Once it is determined whether the first tube joint is a socket or a socket, the subsequent tube joints can be determined automatically. For example, if the junction of the first tube is a socket, the insert of the next tube is inserted into the socket of the first tube, and the socket of the next tube is inserted into the socket of the next tube. It will be done.

  When all pipe installation work is completed, the positions (latitude, longitude) of each joint are calculated by the pipe joint position calculation unit 24, and the pipes calculated by the pipe joint position calculation unit 24 described above by the completed drawing generation unit 22. A piping construction drawing is generated in which the joint positions are allocated to and aligned with the pipe joint positions included in the piping construction drawing.

  Specifically, the pipe joint position calculation unit 24 calculates the position (latitude, longitude) of the pipe joint included in the imaging information based on the photogrammetry technology, the position information (latitude, longitude, altitude) of the flying object 130, Geometrically calculated from posture information (direction of optical axis of imaging device). Since the line connecting the center position of the captured image and the position of the flying object 130 is the optical axis, the latitude and longitude of the center point of the captured image relative to the position information (latitude, longitude, altitude) of the flying object 130 Is determined geometrically. Furthermore, the central point of the captured image and the position of the pipe junction can be geometrically determined based on the scale of the captured image.

Here, the scale of the captured image is obtained based on the following equation using altitude information among the position information of the flying object 130 and the elevation of the ground of the piping installation work site.
1 / scale = focal length of photograph / (photographing height-elevation of the ground of piping installation construction site)
A more accurate pipe joint position can be calculated by determining the scale using the depth information of the digging groove in consideration of the depth of the piping laid in the digging groove.

  In addition, the scale of the captured image should be based on the height of the known plumbing equipment included in the captured information, for example, the length on the image of a fixed length tube with a known length, to use the information on the altitude of the flying object 130. You can also ask for it. That is, the scale can be obtained by dividing the actual distance by the distance on the photograph. In this method, the length of the fixed length tube and the length of the fixed length tube in the captured image may be compared. Here, the length used as the reference is not limited to the fixed length tube, and information such as road width and road marking can also be used as a reference image for obtaining the scale.

  The position of the pipe joint can be identified from the shape of the pipe joint by recognizing the shape of the pipe joint by image processing, and as shown in FIG. Alternatively, the marker member M may be attached and then imaged, and the marker position may be identified by image processing.

  In addition, with respect to the captured image displayed on the operation screen of the terminal connected to the information processing server 120 in order to specify the position of the pipe joint and specify the position of the reference image for calculating the scale of the captured image. The position may be specified using a pointing device such as a mouse, and the actual position or scale may be calculated based on the specified position.

  The completed drawing generation unit 22 has the connection relationship shown in the piping construction drawing generated by the piping construction drawing generation unit 23, the pipe shape obtained from the pipe information, and the position of the pipe joint calculated by the pipe joint position calculation unit 24. Automatically generate a completion map according to (latitude, longitude).

  Furthermore, as described above, the piping joint position (offset) calculation unit 23 geometrically calculates the measurement points and the base points (latitude and longitude) necessary for creating the offset map from the captured image, It is configured to calculate the distance between them.

  In addition, the calculation method which calculates the position of a pipe | tube junction part, a measurement point, and a reference point based on imaging information and GPS positioning information is not restricted to the example mentioned above, It is also possible to obtain suitably using a well-known calculation method. .

  The offset drawing generation unit 26 draws and generates an offset drawing on the layer on which the road drawing of the pipe installation work site is displayed, with the position and distance serving as the measurement point and the base point calculated by the pipe joining position calculation unit 24. The road map is prepared in advance as mapping data in the information processing server 120.
