Each figure shown in FIG. 2 and the like 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 distortion object (a) in which distortion has occurred may exist in the aerial image.

When the operator performs drawing based on the aerial image with the distorted object (a) in this way, an auxiliary image (for example, a 3D image of an object or close-up of an object) taken at the actual location where the distorted object (a) exists image), a drawing image in which distortion is corrected as shown in FIG. 3 is produced through the drawing module 20i of the video drawing machine 20 as a medium.

For example, when the operator inputs a blurring object image output signal through the input device 10, the blurring object image output module 20g displays a plurality of blurring object images stored in the storage DB 40 in FIG. output to the display 30 as shown. 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, an actual blurring object image and an object image extracted together with the blurring object image although not actually blurred are checked. Therefore, when correcting the corrected drawing image, the drawing work for the blurring object and the new object can be done accurately.

12 is a view showing the outline of an actual blurred object in a corrected drawing image according to an embodiment of the present invention, and FIG. 13 is an outline of a non-blurred object according to an embodiment of the present invention. It is a view shown in the corrected drawing image, and FIG. 14 is a view for explaining the corrected drawing image in which the secondary drawing is completed according to an embodiment of the present invention.

After that, when the operator clicks the blurring object image on which the actual blurring has been performed from the plurality of blurring object images output on the display 30 through the input device 10, the image designating module 20h is the blurring object image. By checking the coordinates of the position of the outline of the blurring object image, the outline of the blurring object image is output to the corrected drawing image and displayed on the display 30 as shown in FIG. 12 .

In addition, when the operator clicks a blurring object image that is not blurred from the plurality of blurring object images output on the display 30 through the input device 10, the image designating module 20h By checking the coordinates of the position of the outline, the outline of the blurring object image is output to the corrected drawing image and displayed on the display 30 as shown in FIG. 13 .

In such a state, when the operator manually inputs an actual blurring object image drawing signal through the input device 10, the drawing module 20i displays an outline of the actual blurring object image. Draw so that the objects inside are not displayed.

At this time, the drawing module 20i draws the outline so that the position corresponding to the outline is naturally connected to the surroundings because nothing is expressed in the outline.

Also, when the operator manually inputs the non-blurring image drawing signal through the input device 10, the drawing module 20i draws the outline of the non-blurring object image. Draw like 14.

Meanwhile, in the present embodiment, it is assumed that the operator performs the drawing work manually during the second drawing. However, when a signal is input through the input device 10, the drawing module 20i is designed to automatically make the second drawing. it might be

As described above, the present invention normally draws a distortion object existing in the first aerial image (hereinafter referred to as the existing aerial image) during the initial drawing, and then to the drawing object of the first drawing image (hereinafter referred to as the existing drawing image) corresponding to the distortion object. Enter the normalization code.

On the other hand, when producing an existing drawing image, an operator may make a mistake, and distortion objects may occur in the existing drawing image. Therefore, in the present invention, when performing a drawing update operation based on an existing drawing image, the distortion object in the existing drawing image is corrected by comparing the existing aerial image with the existing drawing image and confirming (recognizing) the distortion 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 diagram 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 update drawing operation is performed by excluding the normalized object to which the normalization code is input.

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

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

In addition, in the present invention, when there is a new object in the new aerial image, the color value of the new aerial image is analyzed, and the new object outline is displayed in the modified drawing image located above the new aerial image by overlapping the new aerial image. By doing so, the corrected drawing image can be quickly first drawn.

In addition, in the present invention, when the outline of the new object is displayed on the corrected drawing image, the operator checks the new object image corresponding to the displayed outline, and cancels the display of the object (for example, a car) that does not require drawing. , it is possible to improve the drawing efficiency when drawing for a large 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 drawn more easily and accurately.

In addition, in the present invention, in a new aerial image, when an outline of a new object is shown in a modified drawing image using a color value, the blurred object outline is not shown, so that the blurred blur By preventing the ring-processed object from being drawn as a new object in the modified drawing image, it is possible to improve the accuracy of the correction of the modified drawing image.

In addition, the present invention extracts the position coordinates of the blurring object and the outline of the blurring object from the new aerial image, and checks a plurality of the blurring objects after the first drawing is made to determine the blur After displaying the outline of the blurring object on the corrected drawing image corresponding to the ring object, the inside of the outline of the blurring object is drawn. Therefore, in the present invention, only the drawing operation of the blurring object can be focused on, and thus the drawing operation efficiency of the blurring object can be improved.

In addition, when extracting the blurring processed object by using the color value from the new aerial image of the present invention, if an object image other than the blurring object is extracted, check this after the first drawing, and Accurate drawing can be performed on unpainted new objects due to blurring object extraction.

The fluid rotating part 440 is composed of a fluid rotating motor 441 and a fluid rotating gear 442 , and the diameter of the fluid rotating gear 442 is the same as the inner diameter of the hollow 433 .

The fluid rotation motor 441 may be operated by being electrically connected to a control unit (not shown) and the like, and as the fluid rotation motor 441 operates, the fluid rotation gear 442 rotates, so that the fluid rotation plate 430 is fluid. It may rotate based on the rotating part 440 .

The fluid accommodating part 460 is disposed under the fluid lower plate 450 and has a hollow cylindrical shape so that a fluid can be accommodated therein. A fluid accommodating hole 461 is drilled in the upper surface of the fluid accommodating part 460 to accommodate the fluid.

The fluid connection part 470 connects between the fluid receiving part 460 and the fluid supply part 410 . That is, the fluid supplied from the fluid supply unit 410 and transferred downward may be accommodated in the fluid receiving unit 460 , and then transferred back to the fluid supply unit 410 through the fluid connection unit 470 .

A one-way valve 471 is coupled to the central portion of the fluid connection part 470 . The one-way valve 471 is the lifting unit 500 and the imaging device coupled to the upper part of the fluid supply unit 410 are shaken by an external impact, so that the fluid pressure inside the fluid supply unit 410 increases and the fluid is transferred downward. At this time, it is not transmitted through the fluid connection part 470 , but is transmitted through the fluid upper plate 420 , the fluid rotating plate 430 and the fluid lower plate 450 .

In other words, the fluid is transferred from top to bottom through the fluid supply unit 410 , the fluid upper plate 420 , the fluid rotating plate 430 , the fluid lower plate 450 and the fluid receiving part 460 as shown by dotted lines in the drawing.

Although not shown, when the rotation through hole 431 of the fluid rotating plate 430 is disposed on the same axis (shortest distance) to form 0 degrees with the upper plate through hole 421 and the lower plate through hole 451, the fluid supply unit ( The fluid supplied from the 410 sequentially passes through the upper plate through hole 421 , the rotational through hole 431 , and the lower plate through hole 451 and is received in the fluid receiving part 460 .

If, the rotation through hole 431 of the fluid rotating plate 430 is rotated (intermediate distance) to form an upper plate through hole 421 and a lower plate through hole 451 and more than 0 degrees and less than 180 degrees, the moving distance of the fluid is also in this changed according to

The frequency applied by external shock or vibration is in inverse proportion to the moving distance of the fluid. That is, in order to control the high-frequency vibration, the moving distance of the fluid must be set short, and in order to control the low-frequency vibration, the moving distance of the fluid must be set long.

As described above, the present invention can provide the best cushioning effect in consideration of the surrounding environment or applied vibration, since the moving distance of the fluid can be varied by rotating the fluid rotating plate 430 .

22 is a view showing a cross-sectional view of the lifting unit according to an embodiment of the present invention.

As shown, the lifting unit 500 according to the present invention includes a lifting case 510 , a lifting rod 520 , a vertical moving plate 530 , an upper stopper 521 , a lower stopper 522 , and an upper elastic part 540 . ), a lower elastic part 541 , a rod through hole 550 and a hydraulic pump 560 .

The lower end of the elevating rod 520 is disposed inside the elevating case 510 and can be lifted up and down. The lifting rod 520 is formed in a cylindrical shape with a full interior, and an imaging device is coupled to the upper end of the lifting rod 520 .

The vertical moving plate 530 is inserted into the elevating rod 520 and disposed between the outer surface of the elevating rod 520 and the inner surface of the elevating case 510 and is formed in a ring shape movable up and down. The inner diameter of the vertical moving plate 530 is the same as the outer diameter of the lifting rod 520, the outer diameter of the vertical moving plate 530 is the same as the inner diameter of the lifting case (510).

The upper stopper 521 is formed to protrude from the side of the lifting rod 520 and is disposed on the upper side with respect to the vertical moving plate 530 . The lower stopper 522 is formed to protrude from the side of the lifting rod 520 and is disposed below the vertical moving plate 530 based on the lower stopper 522 . That is, between the upper stopper 521 and the lower stopper 522, the vertical movement plate 530 is coupled to be movable up and down.

The upper elastic portion 540 is disposed between the lower surface of the upper stopper 521 and the upper surface of the vertical movement plate 530 , and the lower elastic portion 541 is formed between the upper surface of the lower stopper 522 and the vertical movement plate 530 . It is placed between As shown, the normal vertical moving plate 530 is spaced apart from the upper stopper 521 and the lower stopper 522 by a predetermined distance by the elastic force of the upper elastic part 540 and the lower elastic part 541 .

The rod through hole 550 passes through the inside of the lifting rod 520 to allow the fluid to pass therethrough. The rod through hole 550 passes through the elevating rod 520 in the transverse direction and passes through the first transverse through hole 551 and the elevating rod 520 disposed under the upper stopper 521 in the transverse direction. The second transverse through-hole 552 and the lifting rod 520 disposed on the lower stopper 522 and disposed relatively lower than the first transverse through-hole 551 vertically through the first transverse through-hole It includes a vertical through-hole 553 connecting between the 551 and the second transverse through-hole 552 .

In other words, the first transverse through-hole 551 is usually disposed in a space spaced apart between the upper stopper 521 and the vertical movement plate 530 , and in the space spaced apart between the lower stopper 522 and the vertical movement plate 530 . Since the second transverse through-hole 552 is disposed, the fluid inside the elevating case 510 can freely move up and down.

It overcomes the elastic force of 541 and moves downward to close the second transverse through-hole 552 . In this state, when the vertical moving plate 530 moves further lower, the lower surface of the vertical moving plate 530 is in contact with the upper surface of the lower stopper 522 , and the lifting rod 520 is lowered as a whole.
