Each figure shown in FIG. 2 represents a feature and is a schematic representation of an image of an actual feature.

In the aerial image, as shown in FIG. 2, a distorted object (a) in which distortion has occurred may exist.

When the operator performs drawing work based on the aerial image with the distorted object (a) in this way, an auxiliary image taken at the actual location where the distorted object (a) exists (for example, a 3D image of the object or a close-up shot of the object) Image), as shown in FIG. 3 via the drawing module 20i of the image drawing device 20, a drawing image with distortion correction is produced.

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

After the first drawing is made as described above, when an operator inputs a blurring object image output signal through the input device 10, the blurring object image output module 20g of the image plotter 20 is the input device 10 The plurality of blurring object images are output to the display 30 such that the location coordinates of the outline of the corresponding blurring object are matched with the plurality of blurring object images stored in the storage DB 40 by receiving signals from the storage DB 40.

For example, when an operator inputs a blurring object image output signal through the input device 10, the blurring object image output module 20g shows a plurality of blurring object images stored in the storage DB 40 in FIG. As described above, it is output to the display 30. At this time, the operator matches the location coordinates of the outline of the blurring object to the blurring object image.

On the other hand, the present invention checks a plurality of blurring object images as described above, and checks the actual blurred blurring object image and the object image extracted along with the blurring object image although the blurring process was not actually performed. So, when correcting the corrected drawing image, it is possible to accurately perform drawing work for blurring objects and new objects.

FIG. 12 is a diagram showing an outline of an object that has been actually blurred according to an embodiment of the present invention in a modified drawing image, and FIG. 13 is an outline of an object that has not been blurred according to an embodiment of the present invention. It is a view shown in a modified drawing image, and FIG. 14 is a view for explaining a modified drawing image in which secondary drawing is completed according to an embodiment of the present invention.

Thereafter, when the operator clicks through the input device 10 a blurring object image that has actually been subjected to a blurring process from a plurality of blurring object images output on the display 30, the image designation module 20h displays the blurring object image. By checking the position coordinates of the outline of the 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 the unblurred blurring object image from the plurality of blurring object images output on the display 30 through the input device 10, the image designating module 20h displays the blurring object image. By checking the position coordinates of the outline line, the outline line 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 the actual blurring-processed blurring object image drawing signal through the input device 10, the drawing module 20i displays the outline of the actual blurred-processed blurring object image. Draw so that the objects inside are not displayed.

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

In addition, when the operator manually inputs the unblurred blurring object image drawing signal through the input device 10, the drawing module 20i draws the outline of the unblurred blurring object image. Figure 14.

On the other hand, in the present embodiment, it is assumed that the operator performs the drawing by hand during the second drawing, but the second drawing is automatically performed by the drawing module 20i when a signal is input through the input device 10. It could be.

On the other hand, when producing an existing drawing image, an operator may make a mistake and a distorted object may occur in the existing drawing image. Therefore, the present invention corrects the distortion object in the existing drawing image by checking (recognizing) the distorted object in the existing drawing image by comparing the existing aerial image and the existing drawing image when performing a drawing update operation based on the existing drawing image. .

At this time, since the distortion object of the existing aerial image does not match with the normalization object of the existing drawing image corresponding to the distortion object, the normalization object is recognized as a distortion object. Accordingly, 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 normal drawing object inputted with a normal drawing code.

In addition, according to the present invention, after modifying an existing drawing image, a more accurate drawing image can be produced by comparing the corrected drawing image with a new aerial image.

In addition, according to the present invention, when the corrected drawing image is produced, the corrected object is displayed on the existing drawing, so that the existing drawing image can be easily modified.

In addition, in the present invention, when 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 by analyzing the color value of the new aerial image. Thus, the corrected drawing image can be quickly first illustrated.

In addition, in the present invention, when the outline of the new object is displayed on the revised drawing image, the operator checks the new object image corresponding to the displayed outline, and the object that does not need a drawing (for example, a car) is released. In addition, drawing efficiency can be improved when drawing work is performed on the outline of a number of new objects.

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

In addition, in the new aerial image, when the outline of the new object is shown in the corrected drawing image using a color value, the blurred blurring is not shown. It is possible to improve the accuracy of the correction of the corrected drawing image by preventing the ring-processed object from drawing from the corrected drawing image to a new object.

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

In addition, when extracting the blurred 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, and the Accurate drawing work can be performed on new unpainted objects due to blurring processing object extraction.
