At this time, the manager may input the technical data on the defect and progress of the building structure based on the image and the blueprint. This makes it possible for managers at remote sites to ask workers at the construction site to efficiently perform work orders through technical data without having to visit the construction site. And, as described above, by accessing the list of construction status board on the augmentation server 200 and review the technical data recorded as the test result data and answers for the actual building structure, the construction progress and maintenance of the building structure is effectively performed.

As shown in FIG. 3, the augmentation server 200 includes a transceiver 210, a schematic searcher 220, an image processor 230, a technical data manager 240, and a schematic storage 250.

The transceiver 210 performs data communication with the display apparatus 100, the manager terminal 300, and other external devices. For example, the transceiver 210 may receive an image of a construction site or a building structure located at the construction site from the display apparatus 100.

The design search unit 220 searches for a 3D design corresponding to a building structure to be constructed at a construction site or a building structure located at the construction site. Specifically, the schematic search unit 220 obtains coordinate values of the construction site by using the position and attitude information of the point where the image received from the transceiver 210 is photographed, and constructs the construction site based on the coordinate values. Search for a 3D design corresponding to a building structure to be built or a building structure located on a construction site.

In addition, the schematic search unit 220 recognizes an image of a building structure located at a construction site or a construction site through image processing of an image, and based on the recognized construction site or an image of the building structure located at the construction site, You can also search for 3D designs that correspond to building structures that will be built on-site or that are located on construction sites.

In addition, the schematic search unit 220 recognizes an image of a construction structure located at a construction site or a construction site through an image processing process of an image, and recognizes the image of the construction site located at the construction site or the construction site and the above-described coordinate values. Based on the 3D design corresponding to the building structure to be built on the construction site or the building structure located on the construction site can be retrieved.

Here, conventional image processing techniques for extracting object regions in various images may be used. For example, various methods using edge pixel values, feature points, brightness, and saturation of the object regions may be used in image processing techniques. have. This method may also be used when the pattern recognition unit 236, which will be described later, recognizes a pattern of an object.

In this way, the analysis of the object image in the image may be performed, and a design corresponding to the analyzed object image may be searched to generate an augmented image through an augmented reality technique. In this case, a detailed design corresponding to the corresponding image may be provided for each construction process through the analyzed image, and thus, simply display the construction information or a part of the structure of the completed building structure as an augmented image by using a marker or the like. It is possible to overcome the limitation of the use of augmented reality techniques in the conventional building field.

In addition, in another embodiment, the above-described schematic search unit 220 transmits the image information of the image acquired through the image acquisition unit 110 to a database stored in the 3D design diagram, to retrieve the 3D design diagram corresponding to the image information. You can do that. The image information may include information about an image of a construction site or a building structure located at the construction site through image processing of the above-described image.

In addition, the schematic search unit 220 transmits the position and posture information of the point where the image measured by the position and posture information measurement unit 130 is photographed to a database in which the 3D blueprint is stored, and thus the position and posture of the point where the image is taken. You can search for a 3D design that corresponds to the information.

In addition, the schematic search unit 220 is a 3D design diagram of the image information and the position and attitude information of the location where the image measured by the position and posture information measuring unit 130, the image obtained by the image acquisition unit 110 is photographed. May be transmitted to a stored database to search for a 3D design corresponding to the image information and the position and attitude information.

The image processor 230 transmits the 3D design drawing retrieved using the augmented reality technique to the display device 100 by superimposing the image on the construction site or the building structure located in the construction site. Hereinafter will be described in more detail with reference to FIG.

4 is a block diagram of an image processor according to an exemplary embodiment.

Subsequently, the image processor 230 may resize the searched 3D design to correspond to the image of the construction site or the building structure located at the construction site. In this case, the image processor 230 may construct an augmented image by rendering a 3D design drawing based on the position and posture information of the point where the image is captured.

The image processor 230 includes a 3D converter 232 and an augmenter 234. The 3D converter 232 converts the schematic image of the building structure into a 3D form. At this time, the architectural structure design drawings converted from the 2D data to the 3D form through the 3D conversion unit 232 is stored in advance in the above-described design storage unit 250, or the construction searched through the above-described design search unit 220 The structural design diagram may be converted into a 3D form through the 3D converter 232 in real time. To this end, the 3D converter 232 may convert a building structure design into a 3D form based on BIM (Building Information Modeling) in which a planar design (CAD) method is three-dimensional.

The reinforcement unit 234 may resize and overlap the searched 3D design to correspond to the size of the construction site or the building structure located in the construction site, and may include a pattern recognition unit 236 and an image position fixing unit 238.

The pattern recognition unit 236 recognizes a common pattern between an image of a construction site or a building structure located at the construction site and the retrieved 3D design drawing. In this case, the above-described image processing method for object region extraction may be used.

For example, the pattern recognition unit 236 may continuously recognize the foundation pile of the construction site as a reference pattern as an image continuously present in the image. In addition, the pattern recognition unit 236 may recognize the foundation pile on the retrieved 3D design as a predetermined pattern.

The image position fixing unit 238 matches the common patterns recognized by the pattern recognition unit 236 so that the retrieved 3D schematic is fixed to an image of a construction site or a building structure located at the construction site. For example, the image position fixing unit 238 may use the foundation pile of the construction site as a reference pattern, and fix the foundation pile on the searched 3D design to match the reference pattern, such that the retrieved 3D design diagram may be superimposed on the construction site image.

Therefore, it is possible for a worker to perform construction of a more stable and accurate building structure through a blueprint image that is fixedly displayed on a construction site image without being shaken during construction of a building structure.
