[0069]
As shown in FIG. 3A, the left side in the figure is the eyepiece side (operator side: the front side in the figure in FIG. 1), and the right side is the measurement object side (the structure side: the back side in the figure in FIG. 1). When the rotation angle (tilt angle: vertical angle) is determined to be 0.00 ° to 359.99 ° as shown in the drawing, the specification of the movable vertical angle range is, for example, −60.00 ° to + 135.00 ° and angular resolution ± 0.009.
[0070]
As shown in FIG. 1, the CCD camera 22 has a high magnification portion 221 in the form of a CCD camera + zoom lens (equivalent to 600 mm) and a low magnification portion 222 in the form of a CCD camera + eyepiece. ing.

When obtaining a distance between two arbitrary points of a structure, first, two horizontal points of the structure are designated as reference points (two horizontal reference points), for example, as shown in the top view of FIG. Thus, the reference points {circle around (1)} and {circle around (2)} are used. As the reference point (1) (2), the simplest designation is as follows. As shown in FIG. 7 (a), the two points that are the lowest points (contact points with the ground surface) at both ends of the entire structure In this case, for the sake of convenience of explanation, the reference points {circle around (1)} {circle over (2)} shown in FIG.

Next, assuming that the deviation angle (correction angle) θ between the normal line standing from the measurement point P0 of the camera C to the surface including the wall surface of the structure and the absolute angle of the goniometer (correction angle) θ, the reference points (1) and (2) The horizontal angle X1 'and X2', the vertical angles Y1 'and Y2', and the distances L1 'and L2' in ▼, the equation (1) shown in FIG. 5B is established. From this equation, the value of the correction angle θ is obtained. If it calculates | requires, it will obtain | require like (2) Formula of the figure.
[0075]
When the horizontal distance X between the start point P1 and the end point P2 shown in the top view of FIG. 4A and the front view of FIG. 4B is obtained using this correction angle θ, it is shown in FIG. 5C. (3) When the vertical distance Y between the start point P1 and the end point P2 is obtained from the equation (4) as in the equation (5), the equation (6) and (7) shown in FIG. ). Of course, it goes without saying that the shortest distance (distance directly connecting) between the start point P1 and the end point P2 is obtained based on the three-square theorem from the equations (5) and (8).
[0076]
As described above, the outer wall inspection apparatus 1 can measure the distance to an arbitrary point of the structure, and the horizontal angle and the inclination angle (vertical angle) to that point, so-called triangulation (three-dimensional method) The distance between any two points of the structure can be measured by the measurement method), and since the laser distance meter is adopted as the distance meter, the distance can be measured quickly and accurately, and the laser beam is a safety class Since it is 1, it can be measured safely. Further, continuous measurement can be performed by continuous irradiation of laser light, and real-time (imaging) position detection of the camera C can be performed.
[0077]

For example, two common points (1) and (2) are designated on the screen 111, for example, in the captured image of FIG. 7A and the elevation view of FIG. Obtained (S-I-1: see FIG. 7; hereinafter, reference figures for reference (shown in FIGS. 3 to 5 and the like) are shown in parentheses).
[0079]
Here, two points {circle around (1)} {circle around (2)} which are simply the lowest points (contact points with the ground surface) at both ends of the entire structure are designated as common points. In this case, the common points (1) and (2) can be directly designated by a touch instruction on the operation panel 1112 or the mouse 112, and a frame indicating a display area of a captured image or an elevation view in the monitor screen 111 can be used. The display magnification is devised so that the common points (1) and (2) shown on both ends (left and right sides) are displayed (that is, the display frame is fully displayed), and two points are specified by default. (1) and (2) can be designated simply.
[0080]
In this case, if the above points {circle around (1)} and {circle around (2)} in the captured image are grasped as the above-mentioned start point P1 and end point P2 in FIG. 4 to FIG. Is required. At this time, the reference points (1) and (2) (described above with reference to FIGS. 4 (a) and 5 (b)) may be set at points other than the above-mentioned common points. Alternatively, the common point (1) (2) may be set as the reference point (1) (2). Of course, if the set reference point (1) (2) is a common point with the elevation, the reference point may be used as a common point. In either case, the distance between the two points can be easily obtained from the equations in FIG. In addition, since the elevation (data) includes distance data, the distance between the two points of the common point (1) (2) can be obtained, and the result (distance) obtained from the captured image and It is also possible to check by comparing the above.
[0081]
Also, if the captured image and the elevation are the same distance on the display, the display magnification setting is adjusted (adjusted) so that the measured distance in the captured image and the set distance in the elevation are the same. ), The captured image and the elevation can be displayed in the same size on the monitor screen. In this case, the displacement on the captured image and the displacement on the elevation are also displayed when the display image is displayed at different display magnifications, for example, 2 cm on the captured image corresponds to 1 cm on the elevation. It becomes easy to associate. In the above description, the distance is obtained from the captured image or elevation data. However, the distance between the two points of the common point (1) (2) may be directly input as a numerical value by the function of the operation panel 1112. it can.
[0082]
If the distance between two common points (1) and (2) (or reference points (1) and (2)) in the same horizontal plane in the captured image is obtained, the distance between the two points on the monitor screen 111 is obtained. Since the ratio to the number of pixels, that is, the distance between two points / the number of pixels can be obtained, this is then obtained as the length for one pixel (hereinafter referred to as “pixel rate”) (SI-2).
[0083]
With this pixel rate, the movement of the camera C can be traced on the elevation as long as imaging and display are performed at the same magnification. That is, for example, when the center of the finder (field of view) of the camera C is first aligned with the common point (1) and the camera C is moved in the direction of the common point (2), the pixels corresponding to the imaging magnification and display magnification are displayed. The captured image moves only on the display, but since the corresponding distance can be calculated based on the pixel rate, the camera position designation (hereinafter “cursor”) is first aligned with the common point (1) on the elevation. And can be moved by the calculated distance.
[0084]
This can be achieved not only by moving from the common point (1) to the common point (2) direction but also by moving the camera C in an arbitrary position and in an arbitrary direction. This means that the position of the center of the visual field can be traced (tracked) on the elevation. For this reason, at the time of inspection / diagnosis described later, omission and duplication of inspection / diagnosis can be avoided by storing and displaying the already completed position (movement trajectory) on the elevation.
[0085]
Here, the trace position is set as the center of the field of view for easy understanding, but it may be a predetermined point in the field of view, which depends on the initial setting. The cursor to be displayed includes a point cursor indicating the position of a predetermined point such as the center of the field of view, an arrow cursor, a cross cursor, a circular cursor indicating the imaging range (lens image), or a rectangular cursor indicating the display range thereof. Is also available.
[0086]
Conversely, by moving the cursor on the elevation, the imaging position (the center of the field of view of the camera C) can be moved accordingly. Since the outer wall inspection apparatus 1 can remotely control the camera C by controlling the vertical rotation motor 26 and the horizontal rotation motor 27 as described above with reference to FIGS. Alternatively, by designating a cursor in an arbitrary range, the camera C is remotely controlled so as to capture the position or range, and a captured image of the desired position or range is displayed.
[0087]
In addition, by specifying a measurement area on the elevation, it is possible to take an image while moving the camera C at every predetermined distance set (“automatic step feed”). In this embodiment, the remote control is used, but it goes without saying that it can also be performed manually.
[0088]
By the way, in the outer wall inspection apparatus 1, as described above with reference to FIG. 1, the low magnification unit 221 and the high magnification unit 222 enable imaging with a wide range of magnifications. Therefore, by obtaining a coefficient corresponding to the lens magnification, the distance to the inspection / diagnosis target part (diagnosis part) of the structure is measured, and the pixel rate in that state (corresponding to one pixel) Length). Therefore, the pixel rate can be obtained regardless of the imaging magnification and the display magnification, and the length and area can be calculated based on the pixel rate (S-II).
[0089]
It is also possible to change the display magnification of the captured image and the elevation view, for example, display a wide range as an elevation view (small display area), and perform various inspections / diagnosis while grasping the imaging position. (See Figs. 13 and 14)
[0090]
Next, since the outer wall inspection apparatus 1 can create an elevation based on the captured image of the structure to be inspected and at the imaging site, the method (elevation drawing creation method) will be described below.
[0091]
As shown in FIG. 8, first, equipment (outer wall inspection apparatus 1) is installed on the site (S-1-1: see FIG. 9). Here, look for a position where the entire surface of the structure to be imaged (inspected) can be imaged, that is, a position with few obstacles, so that you can proceed with elevation drawing and other operations as quickly as possible without much effort The outer wall inspection apparatus 1 is installed. In addition, when there are trees and other obstacles around the low-rise building and around the building, it is corrected as described later (see FIG. 11).
[0092]
Next, two horizontal reference points (1) and (2) are set in order to obtain a horizontal distance and a vertical distance by a calculation formula based on a distance, a horizontal angle, and a vertical angle that can be directly measured by the camera C. Thus, the correction angle θ is obtained (S-1-2: see FIGS. 3 to 5 and FIG. 7A).
[0093]
Next, a schematic elevation view including the outline of the structure is drawn (S-1-3: see FIG. 7C). In the outer wall inspection apparatus 1, as with the layer function in a so-called graphic tool (concept including all CAD and drawing software, etc.), one or more layers made of a transparent drawing sheet are stacked with the captured image as a background, and the transparency ( Drawing can be performed on a sheet, and by using this, an elevation view described here and drawing for inspection / diagnosis described later can be performed.
[0094]
Here, the contour and other parts of the structure are drawn as a diagram while manually moving the camera C while viewing the captured image. In this case, it is possible to draw an outline of the elevation view by connecting the boundaries between the points having greatly different distances at the adjacent points while displaying the measured distances for the respective points.
[0095]
In addition, by setting the imaging range first, not manually, and tracing (automatic tracing) while automatically scanning the range, the same method (using a diagram where the change in distance becomes large) is used. The outline of the elevation can be drawn automatically. In addition, before this, a portion to be a diagram may be emphasized by an image quality operation (edge enhancement, brightness and contrast adjustment) useful for later-described diagnosis.
[0096]
Next, a point is designated (cursor designation), an image is taken at high magnification, and detailed drawing corresponding to one dwelling unit or the like is performed (S-1-4: see FIG. 10). Here, wall pillars, openings, handrails, and the like can be measured, and sufficient details can be drawn as elevations. Further, the elevation can be completed by copying and copying the dwelling units of the same pattern for each hierarchy and column so that the elevation can be easily and quickly created without the trouble (S-1- 5). For example, as shown in FIG. 7C, only one dwelling unit on the lower left of the first floor is created, and the elevation view of FIG.
[0097]
Here, when the elevation cannot be completed due to an obstacle or the like, the device (outer wall inspection apparatus 1) can be moved and corrected (supplementation (complementation) & correction) (S-1-5-1). For example, as shown in FIG. 11A, when there is an obstacle, the elevational view of FIG. 11A is described above with reference to FIG. By setting a new common point (or new horizontal reference point) with the captured image and drawing the deficit (ie, the part that could not be drawn due to an obstacle), As shown in FIG. 11 (b), the elevation can be completed.
[0098]
The completed elevation is stored in the storage medium (MO disk 40) shown in FIGS. 1 and 2 (S-1-6). Here, in order to facilitate post-processing analysis and calling (reading), an identification code (for example, the name or code of a housing complex or a building: refer to FIG. 17) is attached and stored. In addition, by adding the image classification on the database, it is possible to record drawings for 5 surfaces (front, right side, left side, rear surface, top surface). It can be recorded.
[0099]
Next, a method (inspection / diagnosis method: inspection / diagnostic sheet creation method) of performing inspection / diagnosis at the imaging site, which is the original purpose of the outer wall inspection apparatus 1, will be described.
[0100]
As shown in FIG. 12, first, as in the case of FIG. 8, a device (outer wall inspection apparatus 1) is installed in search of a place with few obstacles on the site (S-2-1: same as S-1-1). : Refer to FIG. 9), select the identification code (compartment name / code, etc .: refer to FIG. 17), and start up (read out) the corresponding elevation and display all or a part thereof (S-2-2) ) After specifying the common point with the captured image and adjusting the magnification (pixel rate), etc. (S-2-3: see FIG. 13), confirm (understand) the imaging position with the cursor K on the elevation view. For easy understanding, elevations are displayed in a wide range and in a small size, and the inspection / diagnosis purpose (target) part (image of the diagnosis part) is displayed in detail at high magnification (S-2-4: see FIG. 14). .
[0101]
Here, with the captured image as the background, one or more layers consisting of a transparent drawing sheet other than the elevation view are stacked, and drawing for inspection / diagnosis can be performed on the drawing sheet. -Stripping, etc .: Refer to FIG. 17) and the inspection result is drawn (S-2-5: Refer to FIG. 15). In this case, the drawing sheet is displayed with a grid that can be seen through at a predetermined interval from the reference point based on the pixel rate, so that a defect (damage) is drawn by drawing on the display screen by a mouse operation or the like. It is clear and the size (length and area) is easily measured.
[0102]
Further, since the type of sorting is defined in the inspection / diagnosis results (see FIG. 17), the contents (damage contents, determination rank, etc.) are sorted and inputted. That is, the outer wall inspection apparatus 1 displays options on the monitor screen 11 as candidates for examination or diagnosis results, and one of them can be selected, so the contents and types to be recorded (recorded) are remembered. Even without it, inspection and diagnosis can be performed easily.
[0103]
In addition, since the position where the inspection has been completed is displayed as an inspection history on the elevation, it is easy to prevent omission and duplication of the inspection / diagnosis by proceeding with the inspection / diagnosis while confirming it. Also, since the imaging (inspection / diagnosis) position of the inspection / diagnosis results so far is associated with the position on the elevation, each diagnosis location is close to the already recorded inspection / diagnosis location Is notified of a warning to that effect. In this case, since the (recorded) contents can be displayed and confirmed on the same screen, duplicate registration can be prevented if they are the same, and if they are different, they can be recorded without omission, or defects can progress even though they are the same. In such a situation, it is possible to observe the progress by recording it repeatedly.
[0104]
Further, when the damaged part is recorded, a symbol indicating that the damaged part is recorded is attached to the corresponding position on the elevation view (corresponding to the drawing sheet for diagnosis). That is, a predetermined sign indicating significance is recorded at a position on the elevation corresponding to the position where the significant inspection result or diagnosis result such as a damaged portion is drawn. It is possible to know whether or not a significant test / diagnosis result is recorded at that position.
[0105]
Further, as described above, by designating the measurement area on the elevation, it is possible to move and image by automatic step feed, and to perform inspection and diagnosis along with it. In addition, since the image quality operation for facilitating the inspection / diagnosis can be performed, it is possible to make the diagnosis unit easier to see. Also in this inspection / diagnosis, when the inspection / diagnosis cannot be completed due to an obstacle or the like, the device (outer wall inspection apparatus 1) can be moved for correction (S-2-5-1).
[0106]
When the inspection / diagnosis is completed, the inspection / diagnosis result (drawing sheet data) is stored in the storage medium (MO disk 40) described above with reference to FIGS. Save (S-2-6). As described above, the inspection / diagnosis results for five surfaces (front, right side, left side, rear surface, and top surface) can be recorded by adding the image classification.
[0107]
Next, as shown in FIG. 16, the medium (MO disk 40) on which the inspection / diagnosis results are recorded is set in, for example, the personal computer 52, and the measurement (by clicking the symbol displayed on the elevation view) (Inspection / diagnosis) Check the result on the display screen of the personal computer 52 (S-3-1), add any comments that could not be entered on site (S-3-2), and report When the necessary data is prepared, a predetermined report (elevation, inspection report determination summary table, etc.) is created and printed by a series of predetermined processing (processing in the facility 50) (S 3-3: See FIGS. 17 to 18).
[0108]
  As described above, in the outer wall inspection apparatus 1 of the present embodiment, the outer wall of the structure to be inspected is imaged and displayed on the monitor screen 111, so that the state of the outer wall can be easily confirmed. At the same position and scale as the captured imageIt is a formed transparent layerThe drawing sheet can be displayed on the captured image so as to be seen through, and the inspection / diagnosis result based on the captured image can be drawn on the drawing sheet. That is, while looking through the damaged part of the captured image, the form of the damaged part (the state of the length, area, etc.) can be drawn as it is on the drawing sheet superimposed on it, so that it can be drawn accurately, and the drawing sheet Since it is stored as image data, it can be converted into data easily and quickly.
[0109]
Further, in the outer wall inspection / diagnosis system 100 of the present embodiment, a predetermined report (see FIG. 18) is created based on the inspection result or the diagnosis result indicated by the drawing sheet stored in the inspection result storage means of the outer wall inspection apparatus 1. Therefore, it is easy to create a report, and since it is converted into data, it can be easily managed as a database or the like.
[0110]
In the above-described embodiment, the monitor device 10 has been described as an integrated type similar to a so-called notebook personal computer (see FIG. 1), but the monitor screen 111 is displayed on the main body (control in FIG. It may be separated from the casing on the part 12 side. Further, the control unit 12 and other internal circuits may be made compact (by thinning or the like) and conversely housed and integrated in a housing on the monitor screen 111 side. Further, the monitor screen 111 that is separate from the main body or the monitor screen 111 that is integrated by incorporating the main body side may be attached to the imaging device 20 side (for example, the tripod 29) or may be detachable. .
[0111]
In these cases, as with the monitor screen 111 of the embodiment, a touch panel configuration having both functions of a display and an operation panel is used, and all operations can be performed by touching (instructing) the screen with a finger or a pen. For example, it is possible to carry around only the monitor screen to an arbitrary place (for example, bring it into the car or the like), and to operate while grasping everything by the screen display. In the above-described embodiment, the monitor device 10 and the imaging device 20 are connected by wire (RS232C). However, a wireless connection may be used, and in this case, remote operation is further facilitated. Of course, other modifications can be made as appropriate without departing from the scope of the present invention.
[0112]
