FIG. 8 is a diagram for explaining processing in the drawing / drawing apparatus 10, and in the drawing 2 of the screen 1, it is possible to prevent the displayable position and the place of interest from being displayed.

== Initialization processing ==
FIG. 9 is a diagram for explaining the flow of the initialization process.
The drawing registration unit 111 receives input of drawing information and registers it in the drawing storage unit 131 (S201). Note that a plurality of drawing information may be stored in advance in the memory 102 or the storage device 103, and the drawing registration unit 111 may receive designation of drawing information to be used from these. The placement possible position registration unit 112 accepts designation of coordinates of the placement possible position and registers it in the placement possible position storage unit 132 (S202), and the place of interest information input unit 113 accepts designation of the coordinates of the place of interest and stores the place of interest information. Registered in the unit 133 (S203). For example, it is possible to display the drawing 2 and allow the position-possible position registration unit 112 and the interest location information input unit 113 to accept designation of coordinates on the drawing 2 by using a mouse or the like. Further, the place of interest information input unit 113 may receive an input of label information corresponding to the designated place of interest.

  The distance calculation unit 114 performs the following process for each of the places of interest information registered in the place of interest information storage unit 133.

  The distance calculation unit 114, for each of the positionable position information registered in the positionable position storage unit 132, the distance between the place of interest included in the place of interest information and the positionable position included in the positionable position information. Is calculated as D (S204), and the location of interest ID included in the location of interest information and the positionable position ID and D included in the positionable position information are associated and registered in the correspondence table 135 (S205). The distance calculation unit 114 sorts the distances (and combinations of positionable position IDs) corresponding to the place of interest ID in the distance table 134 (S206).

  After performing the above processing for each place of interest information, the label position determination unit 115 creates a correspondence table 135 in which a null value (a value indicating that there is no corresponding place of interest) is set in association with each possible position ID. Create (S207). For each piece of interest location information registered in the place of interest information storage unit 133, the label position determination unit 115 corresponds to the placement possible position ID among the placeable position information registered in the placeable position storage unit 132. Among those where the interest location ID is a null value, the one with the shortest distance from the interest location included in the interest location information to the possible location is read (S208), and the possible location ID included in the read available location information If the place of interest ID of the correspondence table 135 corresponding to is included in the place of interest information, it is updated to the place of interest ID (S209).

  The correspondence table 135 after the initialization process is in a state as shown in FIG. FIG. 10 is a table in which the distance table 134 after the initialization process is rearranged with the position-possible position IDs and distances corresponding to the respective places of interest ID. That is, in the correspondence table 135, the arrangement positions of the closest distances are associated with the places of interest A to E, but with respect to the place of interest F, any of the arrangement positions 11, 10, 12, and 5 is the place of interest A. Since it is associated with .about.E, the fifth possible arrangement position 6 is associated. Similarly, the second possible arrangement position 4 is associated with the place of interest G, and the fourth nearest arrangement position 1 is associated with the area of interest H. In the distance table 134 of FIG. 10, the total label distance when the possible arrangement position registered in the correspondence table 135 is the label position is 1253.50. FIG. 11 is a diagram illustrating an example of FIG. 2 in which an arrow 5 is drawn between a possible position and a place of interest according to the correspondence in the correspondence table 135 after the initialization process.

== Optimization processing of label position ==
FIG. 12 is a diagram for explaining the flow of the label position optimization process.
The label position determination unit 115 sets “improved” to the improvement flag (S301), and performs the following processing with each of the interest location IDs of the interest location information registered in the interest location information storage unit 133 as P1.

  The label position determination unit 115 reads the possible position ID corresponding to P1 from the correspondence table 135 and sets it to L1 (S302). The label position determination unit 115 reads the distance corresponding to P1 and L1 from the distance table 134 and sets it as D1 (S303). That is, D1 is the current label distance for the place of interest indicated by P1.

  The label position determination unit 115 searches the distance table 134 for a position corresponding to a distance shorter than the distances corresponding to P1 and L1 among the dispositionable position IDs corresponding to P1 (S304). Each of these is set to L2, and the update process shown in FIG. 13 is performed (S305).

  For example, the distributable position ID corresponding to the place of interest “A” in the correspondence table 135 of FIG. 7 is “5”, and the next distance is the dispositionable position ID corresponding to the place of interest “A” in the distance table 134 of FIG. No update processing is performed because there is no short-positionable position ID. On the other hand, in the correspondence table 135 of FIG. 7, the possible arrangement position ID corresponding to the place of interest “F” is “6”, and in the distance table 134 of FIG. 10, the possible arrangement position ID corresponding to the place of interest “F”. Of these, the update processing is performed with each of the dispositionable position IDs 11, 10, 12, and 5 having a distance shorter than the distance “296.4” corresponding to “6” as L2.

  The label position determination unit 115 repeats the process from step S301 when the improvement flag becomes “true” by the update process after repeating the above process for each place of interest ID (S307: YES).

== Update processing ==
FIG. 13 is a diagram for explaining the flow of update processing. The label position determination unit 115 reads the distance corresponding to P1 and L2 from the distance table 134 and sets it as ND1 (S321). ND1 is a label distance when the label position is changed to an arrangementable position indicated by L2.

  The label position determination unit 115 reads the place-of-interest ID corresponding to L2 from the correspondence table 135 and sets it as P2 (S322).

  When P2 is a null value (S323: NO), the label position determination unit 115 updates the arrangement possible position ID of the correspondence table 135 corresponding to P1 to L2 (S324). As a result, among the possible positions that are not associated with other places of interest, those closer to the label position associated with the place of interest indicated by P1 are associated with P1.

  If P2 is not a null value (S323: YES), the label position determination unit 115 reads the distance corresponding to P2 and L2 from the distance table 134 as D2 (S325), and reads the distance corresponding to P2 and L1. ND2 (S356). Regarding the position of interest indicated by P2, D2 is the current label distance, and ND2 is the label distance when the label position is changed to the possible position indicated by L1. The label position determination unit 115 compares whether the sum of D1 and D2 is greater than the sum of ND1 and ND2 (S327). That is, the label position determination unit 115 determines whether or not the label distance is shortened when the label positions of the places of interest indicated by P1 and P2 are exchanged. When the label distance is shortened when the label position is exchanged (S327: YES), the label position determination unit 115 updates the possible arrangement position ID of the correspondence table 135 corresponding to P1 to L2 (S328), and corresponds to P2. The placement possible position ID of the corresponding table 135 is updated to L1 (S329). That is, the label positions of the places of interest indicated by P1 and P2 are exchanged.

  When P2 is a null value (S323: NO), and when the label distance of the place of interest indicated by P1 and P2 is exchanged, the label position determination unit 115 shortens (S327: YES). The improvement flag is set to “true” (S330).

  As described above, while the label distance is shortened by the update process (while the improvement flag is “true”), the processes in steps S301 to S305 in FIG. 12 are repeated, and the place of interest can be arranged thereby. The label position can be determined so that the total distance between the positions is the shortest.

  FIG. 14 is a diagram illustrating a state of the correspondence table 135 after the label position optimization process is performed. As shown in FIG. 15, the total label distance when the possible position registered in the correspondence table 135 is the label position is 1031.50, and the total label distance 1253 before processing shown in FIG. The distance is shorter than .50. Further, FIG. 16 shows a drawing of the arrow 5 between the arrangement possible position and the place of interest according to the correspondence in the correspondence table 135 of FIG. 14 after the optimization processing.

  As shown in the figure, according to the drawing drawing apparatus 10 of the present embodiment, the label 4 can be displayed as close as possible to the place of interest 3 by the optimization process, and the user can label information about the place of interest 3. It becomes easy to grasp.

  Moreover, according to the drawing drawing apparatus 10 of this embodiment, a label position is determined so that the sum of the distances between the place of interest and the label position is minimized. Therefore, the arrow 5 connecting the place of interest 3 and the label 4 does not intersect. As a result, the arrow 5 that associates the place of interest with the label 4 can be drawn on the drawing 2 in an easy-to-see manner, and the user can easily grasp the label information related to the place of interest using the arrow 5.

  Moreover, according to the drawing drawing apparatus 10 of this embodiment, an arrangement | positioning possible position can be set to arbitrary places. Therefore, if there is a place on the drawing 2 where it is not desired to display the label, the user need not set the position where the label can be placed there. In addition, even when information is drawn on the drawing 2, in a situation where a label may be displayed over the information, a position that can be arranged arbitrarily is set even on the information. If so, labels will be displayed there as needed. For example, when an inspection is performed inside a condominium, and the drawing also includes a common part outside the room, a label is displayed by setting a position where the common part can be arranged. You can also As described above, according to the drawing / drawing apparatus 10 of the present embodiment, the user can arbitrarily set the position where it can be arranged, so that the drawing and drawing apparatus 10 can automatically set a label or the like in an empty place on the screen. While the necessary information on the drawing 2 is not hidden by the label, the label can be arranged on the unnecessary information on the drawing 2, so that the label can be arranged more easily. It becomes possible.

  Further, according to the drawing drawing apparatus 10 of the present embodiment, the user can designate arbitrary positions as the arrangement possible position and the interest place, and therefore drawing information such as a bitmap is drawn in the drawing 2. Even if the image information does not include information about the contents, the label can be drawn for easy viewing.

  Moreover, according to the drawing apparatus 10 of this embodiment, since the distance between all the places of interest and the arrangement possible position is registered in the distance table 134 in advance, the time for calculating the distance is reduced, The optimization process can be executed quickly.

  Moreover, according to the drawing drawing apparatus 10 of this embodiment, the distance table 134 is sorted in advance in order of distance for each place of interest. Therefore, in step S304 of FIG. 12, it is possible to easily search for a disposition-possible position ID that is closer than L1, and the processing speed of the optimum process can be increased.

== Modification ==
In the present embodiment, the position that can be arranged accepts the designation from the user, but it may be arranged automatically at the end of FIG. 2, for example. Further, for example, the size of the drawing, the maximum number of characters of label information that can be displayed on the label 4, the font and font size for displaying the label 4, and the like are set in advance. On the basis of the setting information, the arrangement possible position is automatically calculated according to a predetermined rule, and the arrangement possible position information in which the calculated arrangement possible position is set can be registered in the arrangement possible position storage unit 132.

  FIG. 17 is a diagram illustrating an example of a screen 40 for setting parameters to be displayed when the position-possible registration unit 112 automatically sets the position-possible position.

  A pull-down list 41 on the screen 40 is used for designating a shape for setting a possible position. In the pull-down list 41, “rectangle”, “circle”, and “ellipse” can be selected.

  When “rectangular” is selected in the pull-down list 41, the arrangeable position registration unit 112 sets the arrangeable position in a rectangular shape. On the screen 40, input fields 411 and 412 for setting an offset from the horizontal end of FIG. 2 and input fields 413 and 414 for setting an offset from the vertical end are displayed. The unit 112 sets a position that can be arranged in a rectangular shape inward from the end of FIG. 2 by the offset specified in the input fields 411 to 414. That is, the X coordinate values input in the input fields 411 and 412 are X1 and X2, the Y coordinate values input in the input fields 413 and 414 are Y1 and Y2, the upper left coordinates are (X1, Y1), and the lower right coordinates The disposition position can be set at a predetermined interval (for example, a length obtained by dividing the length of the rectangle side by the number M of disposition positions) on a rectangle side having (X2, Y2).

  When “circle” or “ellipse” is selected in the pull-down list 41, the arrangeable position registration unit 112 sets the arrangeable position in a circular or elliptical shape. The screen 40 displays a slider 415 for setting the center position in the horizontal direction (X axis) in FIG. 2 and a slider 416 for setting the center position in the vertical direction (Y axis). A circle or ellipse on the drawing 2 centered on the X and Y coordinates designated by the sliders 415 and 416 (the diameters of the ellipse in the X-axis and Y-axis directions are obtained from the offsets designated in the input fields 411 and 412. ) On the upper side, for example, it is possible to set the disposition position for each length obtained by dividing the circumference of a circle or an ellipse by M.

  The arrangement position registration unit 112 sets the arrangement interval and arrangement method in the horizontal direction (upper and lower ends of the drawing 2) and the vertical direction (side edge of the drawing 2) when setting the arrangement positions in a rectangular shape. May be changed. For example, the pull-down list 42 on the screen 40 specifies the density of positions that can be arranged in the horizontal direction. In the pull-down list 42, for example, either “twice the vertical direction” or “same as the vertical direction” can be selected. When “twice in the vertical direction” is selected, the disposition position registration unit 112 sets the distance between the disposition positions set at the upper and lower ends to be twice the distance between the disposition positions set at the side edges. The possible arrangement position is set as follows. In addition, it is possible to specify an arbitrary multiple, not limited to two. As a result, since the arrangement of the arrangement positions in the horizontal direction is set wide, it is possible to draw the label 4 in an easy-to-read manner when drawing horizontally written label information on the label 4.

  In the check box 43 on the screen 40, it is specified whether or not the horizontal arrangement possible positions are installed in a zigzag (staggered arrangement). When the check box 43 is checked, the arrangeable position registration unit 112 sets the arrangeable positions to be set in the upper and lower end parts so as to alternately shift in the vertical direction. In the input field 44, an offset for shifting the disposition position is specified, and the disposition position registration unit 112 sets the disposition position by alternately shifting in the vertical direction by the offset specified in the input field 44. As a result, when horizontally-written label information is drawn on the label 4, it is possible to prevent the label information from overlapping as much as possible even when the label position is set at a position where the labels can be arranged adjacent to each other. Can be drawn.

== Other variations ==
In the drawing apparatus 10 of the present embodiment, it is assumed that the drawing 2 is an architectural drawing. However, the drawing 2 is not limited to the architectural drawing, and an arbitrary image can be used.

  In the present embodiment, the drawing 2 is a two-dimensional image. However, the present invention is not limited to this, and may be a three-dimensional image (an image obtained by projecting a three-dimensional solid object onto a two-dimensional plane). In this case, the place of interest and the position where arrangement is possible may be specified by three-dimensional space coordinates, and the label position that minimizes the distance in the three-dimensional space may be determined.

  In the present embodiment, the architectural drawing 2 that is a still image is displayed on the screen 1. However, the present invention is not limited to this, and a moving image may be displayed on the screen 1. In this case, for example, the same processing as in the present embodiment can be performed for each frame constituting the moving image.

  In the drawing drawing apparatus 10 of the present embodiment, the drawing 2, the label 4 and the arrow 5 are displayed on the screen 1, but may be output to an output device such as a printer, a plotter, or a projector.

  In this embodiment, the arrow 5 is drawn from the label position to the place of interest. However, the present invention is not limited to this, and a line (drawer line) connecting the label position and the place of interest is drawn in an arbitrary shape. May be. In the drawing drawing apparatus 10 of the present embodiment, since the label 4 is displayed at the position where the place of interest is as close as possible, the relationship between the label 4 and the place of interest can be grasped without drawing the arrow 5. Therefore, the arrow 5 need not be drawn.

  Further, the drawing apparatus 10 determines the label position by performing initialization processing and optimization processing in response to a request from the user terminal operated by the user, and only the label 4 or the label 4 and the arrow on the drawing 2. The image in which 5 is drawn may be transmitted to the user terminal. Moreover, the drawing apparatus 10 may transmit the label position for each place of interest to the user terminal, and draw the label 4 and the arrow 5 on the drawing 2 on the user terminal.

  In the present embodiment, for the sake of simplicity, only one piece of drawing information is registered in the drawing storage unit 131. However, a plurality of drawing information may be registered. In this case, the place-of-interest information and the position-possible position information can be stored for each drawing information.

Further, in the present embodiment, the label position determination unit 115 uses an arbitrary combination optimization method to calculate the position of interest and the position where the sum of the distance between the position of interest and the position where the position can be minimized. Combinations can also be determined As described above, the present embodiment has been described. However, the above embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. Absent. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
