Each figure shown in FIG. 2 and the like represents a feature, and is a schematic diagram of an image of an actual feature in the form of a figure.

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

When the operator performs drawing based on the aerial image with the distorted object (a) as described above, the auxiliary image (for example, a 3D image of the object or close-up of the object) taken from 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 209 of the video drawing machine 200 as a medium. The auxiliary image capturing of the distorted object (a) is performed through the camera unit 800, which will be described later.

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, the distorted object existing in the aerial image is normally drawn to the drawing object (b), normal Enter the drawing code.

Receives a signal from and outputs the plurality of blurring object images to the display 110 so that the positional coordinates of the blurring object outline are matched with the plurality of blurring object images stored in the storage DB 300 .

For example, when the operator inputs a blurring object image output signal through the input device 100, the blurring object image output module 207 shows a plurality of blurring object images stored in the storage DB 300 in FIG. output to the display 110 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, it is possible to check an actual blurred object image and an object image extracted with the blurring object image although the blurring is not actually performed. 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 diagram showing the outline of an actual blurred object according to an embodiment of the present invention in a corrected drawing image, and FIG. 13 is an outline of an object that is not blurred 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.

Thereafter, 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 110 through the input device 100, the image designating module 208 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 as shown in FIG. 12 and displayed on the display 110 .

In addition, if the operator clicks a blurring object image that is not blurred from the plurality of blurring object images output on the display 110 through the input device 100, the image designation module 208 is By checking the position coordinates of the outline, the outline of the blurring object image is output to the corrected drawing image as shown in FIG. 13 and displayed on the display 110 .

In such a state, when the operator manually inputs an actual blurred object image drawing signal through the input device 100 , the drawing module 209 displays an outline of the actual blurred blurred object image. Draw so that the objects inside are not displayed.

At this time, the drawing module 209 draws the outline so that the position corresponding to the outline is naturally connected to the surroundings because nothing is expressed in the outline.

In addition, when the operator manually inputs the non-blurring image drawing signal through the input device 100, the drawing module 209 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 100, the drawing module 209 is designed to automatically perform 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 adds it 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, the present invention corrects the distortion object in the existing drawing image by checking (recognizing) the distortion object in the existing drawing image by comparing the existing aerial image with the existing drawing image when performing the drawing update operation based on 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 update drawing operation is performed by excluding the normalization 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, according to the present invention, when a modified drawing image is produced, the existing drawing image can be easily modified by displaying a correction object on the existing drawing image.

In addition, the present invention, when there is a new object in the new aerial image, analyzes the color value of the new aerial image, overlaps the new aerial image and displays the outline of the new object in the modified drawing image located above 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 an 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, when the outline of a new object is shown in a modified drawing image using a color value in a new aerial image, the blurred object outline is not shown, so that the blurred blur By preventing the ring processing 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 location coordinates of the blurring object and the outline of the blurring object from the new aerial image, and identifies a plurality of the blurring objects after the first drawing is made, so that 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, according to 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 processing object using the color value from the new aerial image of the present invention, if an object image other than the blurring processing object is extracted, it is checked after the first drawing, and the Accurate drawing can be performed on unpainted new objects due to blurring object extraction.
