FIG. 2 is a diagram for explaining an existing aerial image with a distorted object according to an embodiment of the present invention, and FIG. 3 is a diagram for explaining an existing drawing image in which a distorted object is normally drawn based on FIG. 2 . Each figure displayed in FIG. 2 represents a feature and is a schematic representation of an image of an actual feature in the form of a figure.

As shown in FIG. 2 , a distorted object (a) may exist in the aerial image.

When the operator performs the drawing work based on the aerial image with the distorted object (a), the auxiliary image (eg, 3D image of the object or close-up of the object) taken at the actual location where the distorted object (a) exists As shown in FIG. 3, a drawing image in which distortion is corrected is produced through the drawing module 209 of the image drawing device 200 with reference to the drawing).

At this time, the operator, through the normal drawing code input module 302 of the storage DB 300, among the drawing objects of the drawing image, to the drawing object (b) in which the distorted object existing in the aerial image is normally drawn, Enter the drawing code.

If the boundary line forms a closed loop, the corresponding closed loop is recognized as an object, and the center position of the closed loop object is extracted.

The drawing object position extraction module 213 extracts a drawing object from the existing drawing image output to the display 110 and extracts the center position of the drawing object. At this time, drawing object extraction of the existing drawing image can be extracted by extracting a color value forming a closed loop with a certain color value from the existing drawing image.

4 is a diagram showing a distortion object to be corrected in an existing drawing image according to an embodiment of the present invention, and FIG. 5 is a diagram for explaining a modified drawing image in which an existing drawing image is modified according to an embodiment of the present invention. .

On the other hand, in this embodiment, it is preferable that the new aerial image has a resolution at which the asphalt and the center line constituting the road object can be clearly seen.

Continuing, when building objects and road objects are extracted by the object extraction module 202, the new object display module 203 displays the extracted building objects and road objects of the new aerial image and the building objects and roads of the modified drawing image. The objects are compared, and the outline (d) of the new building object and the outline (e) of the road object of the new aerial image are extracted, excluding the building object and road object of the modified drawing image, and the modified drawing as shown in FIG. Outputs the outline on the image.

Here, it is preferable that the new aerial image is a blurred image with a color value that has a large difference from the color value of an object in the new aerial image.

Here, the present invention can prevent the blurred object from being drawn by excluding the blurred object from the new aerial image when outputting the outline of the new object to the modified drawing image as described above.

And, when the recognition of the blurring object by the new object display module 203 is completed, the blurring object outline storage module 204 stores the location coordinates of the outline of the recognized blurring object and the blurring object outline accordingly.

11 is a diagram for explaining an object image extracted by a blurring object image extraction module according to an embodiment of the present invention.

After the first drawing is performed as described above, when the operator inputs the blurring object image output signal through the input device 100, the blurring object image output module 207 of the image drawing device 200, input device 100 receives a signal from , and outputs the plurality of blurring object images to the display 110 so that the location coordinates of the corresponding blurring object outer lines are matched with the plurality of blurring object images stored in the storage DB 300 .

For example, when an operator inputs a blurring object image output signal through the input device 100, the blurring object image output module 207 displays a plurality of blurring object images stored in the storage DB 300 as shown in FIG. output to the display 110 as described. At this time, the operator matches the location coordinates of the blurring object outline to the blurring object image.

On the other hand, in the present invention, by checking a plurality of blurring object images as described above, it is possible to check a blurring object image that is actually blurred and an object image extracted together with the blurring object image that is not actually blurred. Therefore, when correcting a modified drawing image, the drawing work for the blurring object and the new object can be accurately performed.

Thereafter, when an operator clicks a blurring object image on which actual blurring processing has been performed among a plurality of blurring object images output to the display 110 through the input device 100, the image designation module 208 performs the blurring object image By checking the location coordinates of the outer line of , the outer line of the blurring object image is displayed on the display 110 as it is output to a modified drawing image as shown in FIG. 12 .

In addition, when an operator clicks a blurring object image that is not subject to blurring processing among a plurality of blurring object images output to the display 110 through the input unit 100, the image designation module 208 determines the blurring object image By checking the location coordinates of the outer line, the outer line of the blurring object image is displayed on the display 110 by outputting the modified drawing image as shown in FIG. 13 .

In this state, when the operator manually inputs the drawing signal of the blurring object image that has been actually blurred through the input device 100, the drawing module 209 outputs the outer line of the blurring object image that has been actually blurred. Draw so that objects inside are not displayed.

At this time, the drawing module 209 draws so that nothing is expressed within the outer line, so that the position corresponding to the outer line is naturally connected to the surroundings.

In addition, when the operator manually inputs the unblurred blurring object image drawing signal through the input device 100, the drawing module 209 draws the outline of the unblurred blurring object image. Draw like 14.

Enter normalization code.

Meanwhile, when producing an existing drawing image, a worker may make a mistake and a distorted object may occur in the existing drawing image. Therefore, when performing a drawing update based on an existing drawing image, the present invention compares the existing aerial image with the existing drawing image to confirm (recognize) the distorted object in the existing drawing image, thereby correcting the distorted object in the existing drawing image. .

At this time, since the distortion object of the existing aerial image does not match the normalization object of the existing drawing image corresponding to the distortion object, the normalization object is recognized as a distortion object. Therefore, in the present invention, when checking a distorted object in an existing drawing image, a more accurate updating drawing operation is performed by excluding the normalization object inputted with the normalization code.

In addition, the present invention can produce a more accurate drawing image by comparing the modified drawing image with a new aerial image after correcting the existing drawing image.

In addition, the present invention can easily modify an existing drawing image by displaying a correction object on the existing drawing image when creating a modified drawing image.

In addition, in the present invention, if a new object exists in the new aerial image, the color value of the new aerial image is analyzed, and the outline of the new object is displayed on the modified drawing image positioned above the new aerial image overlapped with the new aerial image. By doing so, the modified drawing image can be rapidly first drawn.

In addition, when the new object outline is displayed on the modified drawing image, the operator checks the new object image corresponding to the displayed outline and cancels the display of an object (for example, a car) that does not require drawing. , drawing efficiency can be improved when drawing work is performed on a number of new object outlines.

In addition, the present invention can easily extract the outline of a road object among new objects in a new aerial image using a color value, so that the road object can be mapped more easily and accurately.

In addition, in the present invention, in a new aerial image, when the outline of a new object is shown in a modified drawing image using color values, the blurring processed object outline is not shown, thereby blurring the blurred object. It is possible to improve the accuracy of correction of the correction drawing image by preventing the ring processing object from being drawn as a new object in the correction drawing image.

In addition, the present invention extracts the location coordinates of the blurring object and the outline of the blurring object from the new aerial image, and after the first drawing is performed, a plurality of the blurring objects are identified to determine the blurring object. After the outline of the blurring object is displayed on the modified drawing image corresponding to the ring object, the outline of the blurring object is drawn. Accordingly, the present invention can focus only on the drawing work on the blurring object, thereby improving the drawing work efficiency of the blurring object.

In addition, when extracting the blurring-processed object using the color value from the new aerial image of the present invention, if an object image other than the blurring-processed object is extracted, it is checked after the first drawing, Accurate drawing can be performed on new undrawn objects due to blurring processing object extraction.

A backflow prevention plate 811 is rotatably coupled to the inside of the height case 810 in contact with the first heat exchange passage 851 connected to the first heat exchanger 850 . The backflow prevention plate 811 can rotate only in the inner direction of the height case 810 to prevent the fluid inside the height case 810 from directly flowing into the first heat exchanger 850 .

Specifically, the supply valve 900 includes a valve case 910, a supply passage 920, a first moving part 930, an intermediate passage 940, a second moving part 950, and a first discharge passage 960. and a second discharge passage 970.

21 (a) is a view showing the state in which the first opening/closing unit 934 closes the middle passage 940, and FIG. 21 (b) shows the first opening/closing unit 934 closing the middle passage 940 ) is open, and FIG. 21(c) is a view showing the second opening/closing unit 954 opening the second discharge passage 970.

The inside of the valve case 910 is partitioned into a temperature sensing chamber 911 and a fluid discharge chamber 912 . A supply passage 920 connecting the temperature sensing chamber 911 and the height case 810 is formed at the lower end of the temperature sensing chamber 911, and the temperature sensing chamber 911 and the temperature sensing chamber 911 are formed at the upper end of the temperature sensing chamber 911. An intermediate passage 940 connecting the fluid discharge chambers 912 is formed. A first discharge passage 960 connecting the fluid discharge chamber 912 and the first heat exchanger 850 is formed on the upper left side of the fluid discharge chamber 912, and the fluid discharge channel 960 is formed on the upper right side of the fluid discharge chamber 912. A second discharge passage 970 connecting the discharge chamber 912 and the second heat exchanger 860 is formed.

The first movable part 930 is mounted inside the temperature sensing chamber 911 and can move left and right according to the temperature of the supplied fluid, and the second movable part 950 is mounted inside the fluid discharge chamber 912 It can move left and right according to the temperature of the fluid supplied from the temperature sensing chamber 911 .

When the temperature of the fluid introduced into the temperature sensing chamber 911 is equal to or less than a preset first temperature (eg, 40 degrees), the first opening/closing unit 934, as shown in FIG. It moves to the left by the elastic restoring force of the moving spring 933 and closes the intermediate passage 940 .

Accordingly, the fluid inside the height case 810 is not transferred to the first heat exchanger 850, and the fluid inside the height case 810 maintains an appropriate temperature so that the height control unit 800 can operate smoothly. let it be

When the temperature of the fluid introduced into the temperature sensing chamber 911 is higher than the first preset temperature (eg, 40 degrees), as shown in FIG. 21(b), the wax inside the first moving case 931 expands and pushes the first moving rod 932 to the right, and the first opening/closing unit 934 overcomes the elastic restoring force of the first moving spring 933 and moves to the right to open the intermediate passage 940.

Accordingly, the fluid passing through the intermediate passage 940 passes through the first discharge passage 960 and is transferred to the first heat exchanger 850 . The temperature of the fluid transferred to the first heat exchanger 850 is lowered through heat exchange with the outside, and is introduced into the height case 810 again through the first heat exchange passage 851 .

At this time, the intermediate flow path 940 and the first discharge flow path 960 are arranged to face each other so that the fluid can move more smoothly. The second opening/closing unit 954 is disposed between the first discharge passage 960 and the second discharge passage 970 so that the fluid can pass through the first discharge passage 960 but not through the second discharge passage 970. make it impossible

When the temperature of the fluid introduced into the fluid discharge chamber 912 is higher than the preset second temperature (eg, 80 degrees), as shown in FIG. 21(c), the wax inside the second moving case 951 expands to push the second moving rod 952 to the right, and the second opening/closing unit 954 overcomes the elastic restoring force of the second moving spring 953 and moves to the right to open the second discharge passage 970.

That is, the wax inside the first moving case 931 expands when the temperature is higher than the first preset temperature, and the wax inside the second moving case 951 does not expand when the temperature is higher than the first preset temperature, and when the temperature is higher than the second temperature. Inflate.

Accordingly, the fluid passing through the first discharge passage 960 is transferred to the first heat exchanger 850, the fluid passing through the second discharge passage 970 is transferred to the second heat exchanger 860, and The temperature of the fluid transferred to the second heat exchanger 860 is lowered through heat exchange with the outside, and is again introduced into the height case 810 through the second heat exchange passage 861.

In this way, the present invention allows heat exchange to occur more actively through the first heat exchanger 850 and the second heat exchanger 860 when the fluid inside the height case 810 has a high temperature higher than the preset second temperature. and can re-supply the cooled fluid more quickly.
