Abstract: Provided is a method of selecting a high-definition image frame of a video by using dynamic information, more particularly, a method of selecting a relatively high-definition image frame from among image frames included in a video by using dynamic information of a camera that has captured the video. The method of selecting a high-definition image frame of a video by using dynamic information has the advantage of quickly and effectively obtaining a large amount of image information from a captured video, and effectively select only image frames with a relatively high definition from among image frames included in the video. In addition, the method of selecting a high-definition image frame of a video by using dynamic information has the advantage of quickly and effectively extracting image frames with a high definition from among image frames included in a video, through a relatively small amount of computation.

Abstract: Provided are a method and apparatus for identifying the presence of a 3D object using an image. According to the method and the apparatus, two-dimensional images are used to identify whether a 3D object exists in the images. According to the method and apparatus for identifying the presence of a 3D object by using an image, the presence of a 3D object in space can be accurately and quickly identified by using two-dimensional images, leading to higher productivity.

Abstract: Provided are a method and apparatus for calculating three-dimensional coordinates using photographic images, and more particularly, a method and apparatus for calculating three-dimensional coordinates using photographic images in which a plurality of photographic images are analyzed to calculate the three-dimensional coordinate of a point commonly marked on the photographic images. By using the method and apparatus for calculating three-dimensional coordinates using photographic images captured by a camera, three-dimensional coordinates of arbitrary points marked on the photographic images can be easily calculated.

Abstract: Provided are an apparatus and method of three-dimensional reverse modeling of a building structure by using photographic images, and more particularly, to an apparatus and method of three-dimensional reverse modeling of a building structure by using photographic images, in which three-dimensional modeling data of a building structure may be quickly and conveniently reversely modeled by using a plurality of photographic images. According to the apparatus and method of three-dimensional reverse modeling of a building structure by using photographic images, three-dimensional modeling data of a building structure may be reversely modeled by using photographic images of the building structure captured using a camera, at low costs and quickly and easily, thereby remarkably increasing the productivity of the manufacture of a building information model (BIM).
