Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on images of features (power lines and trees, cranes and power lines, buildings and buildings, antennas and buildings, antennas and power transmission lines, etc.) taken by a camera. The present invention relates to a separation distance information providing system for calculating a distance and transmitting the charge to a contractor terminal (a logging company, a building construction company, etc.) that requires the separation distance and charging the distance.

[0002]

2. Description of the Related Art Generally, power transmission lines between steel towers are stretched with a predetermined slack. For this reason, the trees near the transmission line (hereinafter,
It becomes impossible to keep the distance of the tree under the transmission line).

Such a tree under the power transmission line has hitherto been operated by a dedicated worker of an electric power company actually under the power transmission line, and the tree under the power transmission line (when the power line is swayed by the wind or collapsed). In such cases, it was common to check the distance between the transmission line (including trees that may come into contact with the transmission line) and the transmission line (hereinafter referred to as the separation distance), and to perform logging if necessary.

The above-mentioned separation distance was analyzed by a few workers of a logging company who went to the site to photograph the trees of interest with a digital camera, then went down the mountain and brought this photographed video into an office. Determine the separation distance to determine whether or not logging has occurred. After a few weeks, a few people went to the site and felled the target trees to ensure safety.

On the other hand, a crane is used in building construction, etc., and when there is a power transmission line, etc., it is generally common to measure a distance greater than the reference distance by visual measurement or triangulation and maintain the distance. .

In the construction of a bridge, in order to build a bridge in a place where the river width is wide, the bridge is built from both sides. At this time, the degree of progress of the work was measured by visual measurement or triangulation.

[0007]

However, in the method as described above, a few people climb the mountain, photograph the target tree and the power transmission line from the steel tower with a digital camera, and return to the office to obtain the separation distance. . Then, when it is judged that the separation distance is dangerous, a few people climb the mountain again to cut the target tree, so that there is a problem that it takes a lot of work time, resulting in high cost.

Further, when a tree judged to be dangerous is felled, if the tree is not the tree, the tree is climbed up again, the tree and the transmission line which are considered to be the object are photographed by the digital camera, and then the mountain is descended. Must be analyzed at the office.

That is, when a photograph is taken of a tree that is not a dangerous tree, there is a problem that the work period is doubled and the cost is further increased as a result.

Further, regarding the trees to be felled, the workers go to the site and judge empirically from the thickness of the trunk, the topography and the like.

However, even if a tree can be felled only with the permission of the owner, there are cases where the branches of the tree of the owner who have not given the permission to grow grow near the transmission line. is there.

[0012] In the case of such a tree, since it is necessary to return to the office and inquire by the site section, telephone or fax, there is a problem that it takes time and labor before logging.

On the other hand, with regard to the separation distance that cannot be measured by people such as buildings and power transmission lines, bridges, cranes and power transmission lines, it is a rough separation in the case of visual measurement, and it takes time and cost in the case of triangulation. was there.

The present invention has been made to solve the above problems, and provides a system for reducing the cost by receiving an image from a worker of a contractor who needs a separation distance and immediately providing the separation distance. The purpose is to get.

Next, a series of processes will be described based on the sequence diagram of FIG. 6 is a display example of the screen of the communication terminal 5, and FIG. 7 is a display example of the screen of the separation distance providing device 6.

First, the photographer 12 climbs to a predetermined photographing position of the steel tower C1 and photographs the obstacle tree 3 under the power transmission line and the power transmission line 2 by using the rangefinder 4. After photographing, the user descends from the steel tower C1 and connects the digital camera 8 and the communication terminal 5 (or attach a recording medium to the communication terminal 5). When the image capture button shown in FIG. 6A is selected, the captured image is transferred to the communication terminal 5 (d1). The images are transferred to the left and right cameras separately, and the transferred images are displayed on the display unit (FIG. 6B) at the upper right of the screen.

Next, the photographer 12 inputs the steel tower number, the area number, and the logging company number (FIG. 6 (c)). The tower number is a reference value for identifying the position of the tree 3 under the power transmission line, and when transmitted to the separation distance providing device 6, three-dimensional coordinates indicating a preset shooting location for each tower, It is converted to the azimuth coordinate of the steel tower, and is used to determine the azimuth coordinate of the tree 3 under the power transmission line. The area number is used to specify the landowner of the place where the tree 3 under the transmission line exists. Note that the area number can be specified by the tree position calculation unit, so if it is unknown, it is not necessary to input it. The logging company number may be directly entered as the logging company number.

Next, when the photographer 12 selects the photographing information transmission button of FIG. 6 (d), the image information, the tower number, the area number, the logging company number and the date are transmitted to the separation distance providing device 6 as the photographing information. (D2). If you select the felling availability inquiry button in Fig. 6 (e), the necessary information as shown in Fig. 6 (f) and the confirmation message of the charge will be displayed. Select the necessary information. Then O
When K is selected, an information request and an inquiry as to whether or not logging is possible are transmitted to the separation distance providing device 6 (d3). Note that FIG. 6 (f)
In the figure, ● indicates information required by the logging operator 14, and ○ indicates information not required. Unless you request this information and inquire about whether or not logging is possible, information such as separation distance will not be provided and no information fee will be charged.

Upon receiving the photographing information from the communication terminal 5, the separation information providing device first displays left and right images on the upper part of the screen (FIG. 7 (j)). Inquiries about the tower number, area number, and whether or not logging is possible are also displayed according to FIG. 7 (k).

Next, the operator 13 selects the point designating button in FIG. 7 (m), and in the displayed images on the left and right, the tip of the tree 3 under the transmission line and the tree 3 under the transmission line are approached. The two points of the transmission line 2 that is being used are designated. And FIG.
When the analysis start button of (n) is selected, the tree position calculation unit calculates the position of the photographed tree 3 under the transmission line (d).
4) The separation distance calculator calculates the separation distance between the two designated points (d5).

FIG. 8 is a flow chart showing the procedure for calculating the separation distance. The process of the tree position calculating unit is step S7, and the process of the separation distance calculating unit is steps S8 and S.
It becomes 9. The details will be described below.

As shown in FIG. 9, the tree position calculating unit measures the photograph coordinates of the point of interest (object: transmission line 2, tree) designated on the screen, and measures the photograph coordinates. The internal orientation that defines the internal orientation element for conversion into the system, the model coordinate value (Xm
1, Ym1, Zm1), (Xm2, Ym2, Zm2), mutual orientation, and external orientation for converting these model coordinate values into the left camera coordinate system. The calculated coordinates are
Converted to azimuth coordinates based on the tower number. At this time, if the area number is not transmitted from the communication terminal, the area in which the tree 3 under the power transmission line is located is specified based on the bearing.

Also, the separation distance calculation unit is a target object p1 (x1, y1, z1), p2 defined in the left camera coordinate system.
The difference between the space vectors of (x2, y2, z2) is calculated as the separation distance. That is, various data (distance to the measurement target, depth of the measurement target) can be obtained by shooting with the two digital cameras 8 with the length B of the reference rod 9 fixed. Using this principle, in the present embodiment, a coordinate system (X, Y, Z) is constructed with the projection center of the image of the left camera as the origin, and the left camera of the transmission line 26 on the coordinate system of the left camera After obtaining the point image (X, Y, Z) and the point image of the apex of the tree 37 under the transmission line of the right camera on the coordinate system of the left camera, the space vector between these two points is obtained. Calculate the separation.

(Model coordinate calculation method) In the model coordinate calculation, the model coordinates are obtained using the specifications (internal orientation elements) obtained by the mutual orientation of the equation (7.1).

[0042]

[Equation 1] Therefore, the model coordinates are camera coordinates (Xm, Ym, Zm).

That is, ω1 does not exist in the above equations. That is, by using the reference rod 2, ω1 = ω
It means that the model coordinates are determined as 2.

(Calculation Method of Absolute Coordinates) An equation for converting the model coordinate values to the coordinate system of the left camera using the model coordinate system is shown below. The following formula uses a trigonometric function.

[0045] X = S ・ R ・ Xm + X0 (14) Y = S ・ R ・ Ym + Y0 (15) Z = S ・ R ・ Zm + Z0 (16) The rotation matrix of R is a unit matrix as follows.

[0046]

[Equation 2] Then, when the distance between two points of the transmission line and the tree under the transmission line, which is the point of interest, is to be obtained, the difference square root of X, Y, Z is obtained.

Point p1 (X1, Y1, Z1) Point p2 (X2, Y2, Z2)

[Equation 3] As shown in FIG. 9, a reference rod is used in advance to create a geometric condition in which the object, the lens center, and the image on the film surface form the same straight line in the model coordinates where the three points have the same coordinate system. When measuring the distance between the electric wires, two digital cameras are used to take an image, and the points for finding these image data can be easily defined in the left camera coordinate system of the reference rod 2. That is, by simply designating two points on the screen, the separation distance between them can be obtained.

Further, as shown in FIG. 10, the felling judging unit decides whether or not the felling is necessary based on the separation distance and the flexure or sway of the power transmission line 2. The judgment is made for the following four items, and if even one item has a value less than or equal to the predetermined separation distance, it is judged that logging is necessary (d6). In addition, depending on the calculated value, information on the level of felling required, such as “cutting required (emergency)”, “dangerous”, and “not required”, will also be provided.

(1) When the maximum power is not supplied to the power transmission line 2 (normal power transmission), the separation distance between the power transmission line 2 and the tree is calculated in a windless state. (2) In normal power transmission, find the separation distance in the presence of wind. (3) When the maximum power is supplied to the power transmission line 2, the separation distance in a windless state is calculated. (4) When the maximum power is supplied to the power transmission line 2, the separation distance in the presence of wind is obtained.

Among these processes, the process (1) will be described as a representative.

As shown in FIG. 10, first, the fulcrum coordinate Ta of the steel tower Ja in the local coordinate system (XR, YR, ZR) is shown.
A straight line Lb connecting 1 and the fulcrum coordinate Tb1 of the steel tower Jb is obtained.

Next, the parabola calculation step 4 reads the normal transmission power condition Ha, and using this condition Ha, as shown in FIG. 3, in the local coordinate system, the parabola Ld (L
d: Obtain a, b, and c of the quadratic equation ax2 + bx + c. ). This parabola Ld is represented by the equation described below. However, only the Ld formula on the ZR axis is shown.

[0053]

[Equation 4] Then, the swing compass length determination step 5 is the steel tower Ja and the steel tower J.
A tree Ki near b is searched to determine whether there is a tree Ki.

When a tree Ki exists, the coordinates (kx, ky, kz) at the root of the tree are used to determine X in the local coordinate system.
Draw a perpendicular line Lf to the R axis. Next, after the straight line Lbb is obtained by projecting the straight line Lb on the XR-YR coordinate system of the local coordinate system, an intersection point dk that intersects the straight line Lbb and the perpendicular line Lf.
Ask for.

Next, a perpendicular line Lc is obtained from the intersection point dk with respect to the straight line Lb, and an intersection point d between the perpendicular line Lc and the parabola Ld.
i is obtained, and a separation calculation process based on the obtained intersection point di is performed.

In the case of the processing of (1), the separation calculation step 9 judges whether the vertex kz of the tree Ki with respect to the intersection point di is the upper case or the lower case, and in the case of the upper case, the trunk of the tree. The parallel distance from (draw the kz line) to the vertical line Lc is obtained. In the case below, the separation distance (static separation)
Calculates the stationary distance Cs from the intersection point di to the vertex (kz) of the tree Ki as shown in the following equation.

[0057]

[Equation 5] The calculation result is displayed in FIG. Operator 1
3 selects the logging permission / inquiry button shown in FIG. 7 (q) (d7), the logging management information of the corresponding area is extracted from the land management information 11 at the land management center 7 (d8),
Logging OK or logging NG is transmitted to the separation distance providing device 6 and displayed in FIG. 7 (p) (d9). When the operator 13 selects the location display button of FIG. 7 (r), the map information as shown in FIG. 11 is read from the magneto-optical disk and displayed together with the calculation result of the tree position. You can check the result as an image. In addition, in FIG. 11, a triangle shows a steel tower and a broken line shows the power transmission line 2. Also, the black circles indicate the location where the image was taken, and the × indicate the position of the tree 3 under the power transmission line.

The operator 13 confirms each calculation result,
If there is no problem, each calculation result and information on whether or not logging is possible are transmitted to the communication terminal 5. When the operator 13 selects the position / separation distance information transmission button in FIG. 7 (s), FIG. 7 (t)
Message is displayed, and if OK is further selected, the information required by the felling operator 14 among the calculation results, the map information, and the information on whether or not logging is possible is transmitted to the communication terminal 5 (d10). At the same time, each calculation result and information on whether or not logging is possible are registered in the logging information 10 of FIG.

After sending the calculation results and the like, the operator 1
3 selects the billing information transmission button of FIG. 7 (u), the fee calculation unit calculates the information fee (d11). A unit price is set for each of the information charges, and the information charges are accumulated according to the information provided to the logging operator 14. After the charge is calculated, the message in Fig. 7 (v) is displayed. If you select OK, the calculated information fee and the charge will be sent to the logging company and the bank specified by the logging company number. (D1

The communication terminal 5, which has received each calculation result and the map information, displays each calculation result in FIG. 6 (g) and the map information in FIG. 6 (h). The displayed information is provided to the logging operator 14. When it is displayed that there is no need to cut down, the photographer 12 photographs another obstacle tree 3 under the power transmission line (d15). Further, even when it is displayed that there is no permission to cut the tree, the photographer 12 photographs another tree 3 under the power transmission line (d16).

In this way, the under-transmission-line obstacle tree 3 is photographed from a predetermined position, and the position of the under-transmission-line obstacle tree 3, the distance, and the necessity of logging are calculated from the information such as the photographed images. Furthermore, by providing the felling operator 14 with the information on whether or not the tree under the transmission line obstacle 3 exists, the felling operator 14 can easily identify the tree 3 under the electricity transmission line. The effect of being able to shorten the time required for logging work is achieved. Also,
Providing the information required by the felling operator 14 has the effect of being able to charge an appropriate information fee.

<Second Embodiment> In the first embodiment,

It receives radio waves from GPS satellites, displays its own current position on the screen, and is equipped with a wireless LAN function. It builds an intranet with the communication terminal 5 and the separation distance providing device 6, and the communication terminal By receiving the calculation result and the map information from 5, the map information and the current position are displayed in an overlapping manner. In addition, a general-purpose port such as a USB is provided, and when the communication state of the wireless LAN is poor, each information is received using the connection cable. For other configurations,
This is the same as in the first embodiment.

FIG. 12 is a sequence diagram showing a series of processes. It should be noted that the process up to the transmission of the calculation result and the like to the communication terminal 5 is the same as that in the first embodiment, so detailed description will be omitted.

First, based on the image taken by the digital camera 8, the position information of the target, the separation distance and the necessity of felling, felling OK or felling NG are transmitted to the communication terminal 5 (d1 to d10). . When it is displayed that there is no need to cut down, the photographer 12 photographs another obstacle tree 3 under the power transmission line (d15). Further, even when it is displayed that there is no permission to cut the tree, the photographer 12 photographs another tree 3 under the power transmission line (d16).

Next, the photographer 12 transmits the calculation result and the map information to the communication terminal 5 via the GPS terminal 15 (d21).
When the operator 13 selects the GPS terminal transfer button in FIG. 6 (w), the map information as shown in FIG. 13 is displayed on the GPS terminal 15. The felling operator 14 identifies the target tree 3 under the power transmission line based on the displayed map.

In FIG. 13, the triangle indicates a tower and the broken line indicates the power transmission line 2. The star symbol indicates the current position of the GPS terminal 15, and the x symbol indicates the position of the tree 3 under the power transmission line. By having the logging operator 14 carry the GPS terminal 15,

In the present embodiment, a model is assumed in which the position and the separation distance of the power transmission line 2 and the tree 3 under the power transmission line are calculated and the information is provided, but a building under construction as shown in FIG. 14 is assumed. It can be applied to a model in which a distance that a person cannot directly measure is calculated and information is provided, such as a relationship between the tip of the arm of a crane installed above and the power transmission line 2.

[0074]

As described above, according to the present invention, adjacent digital features are photographed by the digital camera of the rangefinder, and the stereo image is transmitted from the portable terminal device to the distance providing device by the wireless network.

The separation distance providing device receives the separation calculation request data from the portable terminal device, and when the designation of the predetermined points is designated in this stereo image, the separation distance between the points is obtained, and the separation distance is obtained through the wireless network. The service charge for the separation calculation, the trader code, and the date are stored in association with each other, and then transmitted to the terminal of the trader to which the worker belongs via the computer network.

Therefore, when the stereo image is transmitted from the site, the separation distance is immediately transmitted to the portable terminal device, so that the worker can immediately obtain the separation distance at the scene, and the work period can be shortened. As a result, the effect that the cost for calculating the separation distance can be reduced is obtained.

To be done.

Therefore, as in the conventional case, since the worker is from the mountain and the image taken by the digital camera is not analyzed in the office, the separation distance can be immediately obtained on the spot.
The effect that the period for obtaining the separation distance can be greatly shortened and, as a result, the work cost can be reduced is obtained.

Further, when the separation distance is calculated, the service charge is transmitted to the terminal of the trader via the Internet, so that the separation distance providing device can immediately collect the service charge.

Further, even when a person such as a building and a power transmission line, a bridge, a crane and a power transmission line cannot perform measurement, a stereo image captured by a rangefinder is transmitted from the mobile terminal device, and the separation distance providing device transmits the stereo image. , The separation distance is immediately transmitted.

For this reason, there is no need to use triangulation or the like, and the effect is that the cost can be reduced.
