Description

[0001] APPARATUS AND METHOD FOR GENERATING MOSAIC IMAGE USING ASSISTANT INFORMATION [0002]

Embodiments of the present invention relate to a technique for regenerating a mosaic image using auxiliary information relating to a relationship between a unitary image and a mosaic image.

Observation widths are limited for images taken by satellite or aircraft cameras. Therefore, when a large-area image is required, a mosaic image generating apparatus needs a process of mosaicing a plurality of images.

After the mosaic image is finally completed, when the user correction request is input, the mosaic image generating apparatus must repeat the image processing process performed previously.

Particularly, since the position information of the unit image used for making the mosaic image does not provide the level of precision necessary for generating the mosaic image, the mosaic image generating apparatus generates the mosaic image Since the positional information is corrected, the user is required to repeat the procedure manually involved in the process of mosaic image correction, so that the user feels uncomfortable.

When a mosaic image is automatically generated using a computer algorithm, there are high and low precision images. For example, in the case of urban areas, computer algorithms can accurately extract the same point using a subject such as a building, but in the case of a forest area, the same point can not be accurately extracted in many cases. Particularly, when the photographing time is different, the accuracy decreases significantly. For this reason, the user manually participates in the processing when creating the mosaic image.

In addition, since the unit image and the grid of the mosaic image do not coincide with each other during the process of generating the mosaic image, the mosaic image generation device must perform sampling during the process of generating the mosaic image.

At this time, the mosaic image generating apparatus can perform sampling using a preset interpolation method, but it does not perform sampling with a different interpolation method according to the user's selection, and thus has difficulty in satisfying a user's request. If the user requirement differs from the pre-generated mosaic image, it is necessary to repeat the mosaic generation process. In particular, the mosaic generation process takes much time and expense because the procedure involved in the mosaic image generation process must be manually performed.

In accordance with the present invention, a detailed image processing process for generating a mosaic image from a unitary image by regenerating a mosaic image using auxiliary information relating to the relationship between the unitary image and the mosaic image and the unitary image is performed again And it is intended to simplify the generation process of the mosaic image without repeating it.

An object of the present invention is to generate and provide a customized mosaic image by extracting correction information from a correction request and regenerating the mosaic image from the unit image and the auxiliary information based on the extracted correction information.

According to another aspect of the present invention, there is provided a method of generating a mosaic image, the method comprising: identifying a mosaic image associated with the updated unit image using the auxiliary information when the unit image is updated; And to easily update the mosaic image.

The apparatus for generating a mosaic image using auxiliary information for achieving the above object comprises a constituent unit for constituting auxiliary information on a relation between a unitary image and a mosaic image generated by using the unitary image, And a processor for reproducing the mosaic image from the unit video and the auxiliary information based on the extracted correction information.

According to another aspect of the present invention, there is provided a method for generating a mosaic image using auxiliary information for achieving the object, the method comprising: constructing auxiliary information on a relationship between a unit image and a mosaic image generated using the unit image; Extracting the correction information, and regenerating the mosaic image from the unit image and the auxiliary information based on the extracted correction information.

According to the embodiment of the present invention, in cooperation with the correction request, the mosaic image is regenerated by using the auxiliary information related to the relationship between the unitary image and the mosaic image and the unitary image, The generation process of the mosaic image can be simplified without repeating the image processing process.

According to the embodiment of the present invention, it is possible to generate and provide a customized mosaic image by extracting the correction information from the correction request, and regenerating the mosaic image from the unit image and the auxiliary information based on the extracted correction information.

In addition, when the mosaic image is generated including a part of different unit images for each season, when the season is further extracted from the correction request, the processor 103 generates a unit image corresponding to the extracted season in the different unit images for each season And reproduce the mosaic image so that a portion of the mosaic image that is not related to the selected unit image has a set similarity with the image value of the selected unit image.

The processor 103 detects and provides a change in the time-based image value from the regenerated mosaic image when the mosaic image includes a part of different unit images over time, thereby enabling to grasp the image change with time .

2 is a view for explaining an example of generating a mosaic image in a mosaic image generating apparatus using auxiliary information according to an embodiment of the present invention.

2, when the 'A' unit image 201 and the 'B' unit image 203 are input, the mosaic image generating apparatus using the auxiliary information generates a mosaic image using 'A' unit image 201 and 'B' The mixing image 205 can be generated by superimposing the image 203 on the screen. The mosaic image generating apparatus using the auxiliary information can generate the mosaic image 207 as a set region or a selected region in the mixed image 205.

Here, the mosaic image generation apparatus using the auxiliary information samples the left part of the mosaic image 207 in the 'A' unit image 201 and the right part of the mosaic image 207 in the 'B' unit image 203 Can be sampled.

At this time, (1,1), (1,2), (1,3), (2,1), (2,2), (2,3) of the mosaic image 207 are ' 201, and (1,4), (2,4) can be extracted from the 'B' unit image 203.

That is, the mosaic image generating apparatus using the auxiliary information can change the portion related to the specific unit image in the mosaic image to another image using the auxiliary information.

For example, it is assumed that the mosaic image generating device using the auxiliary information is a video image of 'A' unit image taken in 'March 2010', and 'B' unit image 203 taken in 'March 2011' When a 'C' unit image is acquired in 'September 2011' for an area corresponding to the 'A' unit image 201, only 'A' unit image 201 ' The mosaic image can be regenerated by replacing the content related to the C 'unit image.

In addition, the mosaic image generating apparatus using the auxiliary information can perform image processing around the boundary by checking the information on the boundary of the image using the auxiliary information.

For example, when a mosaic is generated from images photographed in spring, summer, autumn, and winter, You can adjust the color to make it feel spring, or you can adjust the color to make it feel summer.

For example, if the 'A' unit image 201 is an image photographed in 'March 2010' and the 'B' unit image 203 is an image photographed in 'September 2011', the auxiliary information is' A The photographing time information of the unit image 201 and the photographing time information of the unit image 203 of the 'B'.

In order to analyze and understand the physical characteristics of the observed object, when the information about the photographing time is provided together with the satellite image, when the user inputs a request to make the mosaic image feel spring, the mosaic image generating device The coloring can be adjusted so that a portion related to the 'B' unit image 203 is made to have a feeling similar to that of the 'A' unit image 201. If the user inputs a request to make the mosaic image fall, the mosaic image generation device using the auxiliary information may generate a similar portion to the 'B' unit image 203, The color tone can be adjusted so as to be obtained. At this time, the mosaic image generating apparatus using the auxiliary information can be performed by using various image processing techniques in the color adjustment.

In addition, when the mosaic image is generated including a part of the unit image that differs in time, the mosaic image generating apparatus using the auxiliary information can detect a change in the image value from the regenerated mosaic image over time.

That is, the mosaic image generating apparatus using the auxiliary information can support the time series analysis using the time information of the unit image. For example, when a mosaic image generating apparatus using auxiliary information performs time series analysis using a plurality of mosaic images for a region of interest, a unit pixel change in a time axis is performed using time information of a unit image constituting a mosaic image Can be confirmed.

For example, the first mosaic image is generated as' A 'unit image 201 of' March 2010 'and' B 'unit image 203 of' September 2010 ', and the second mosaic image is generated as' 2010 A 'unit image in the first mosaic image and a' D 'unit image in' December 'in the first mosaic image are generated from the' C 'unit image of' July ' And the second mosaic image corresponds to the 'D' unit image, it can be confirmed that the image of the region of interest is the 'March' and the 'December' image, and the graph of the relationship between the time and the image value can be easily You can draw.

Referring to FIG. 4, a mosaic image generating apparatus using auxiliary information includes positional information of a unit image and a mosaic image, and includes unit images corresponding to mosaic image pixels, a coordinate transformation function, and a coordinate transformation function Additional correction values can then be constructed. For example, the mosaic image generating apparatus using auxiliary information may be configured to generate a mosaic image pixel position information of (1, 1), an 'A' unit image as a unit image corresponding to a mosaic image pixel, a 'function 1' After applying the coordinate transformation function, '(0.1, 0.1)' as an additional correction value can be constructed. In addition, the mosaic image generating apparatus using auxiliary information includes a 'B' unit image as a unit image corresponding to a mosaic image pixel, a 'function 3' as a coordinate transformation function, After applying the coordinate transformation function, '(0.1, -0.1)' as an additional correction value can be constructed.

Here, the coordinate transformation function in the unit image 'A', the coordinate transformation function 'function 3' in the unit function image 1 and the unit image B can be expressed by Equation (1).
