Abstract: PURPOSE: A multimedia application system using metadata for a sensory device and a method thereof are provided to add a sensory function about moving picture color reproduction made by an intention of a producer from moving picture content production to final consumption, thereby providing a consumer customized high quality multimedia service. CONSTITUTION: A sensory device engine unit(108) receives SEI(Sensory Effect Information) according to moving picture contents. The sensory device engine unit receives UPI(User Preference Information) of the sensory device(114~120). When DCI(Device Capability Information) is inputted, the sensory device engine unit generates SDC(Sensory Device Commands) for controlling the sensory device based on the input information. A sensory device controller(110) controls each sensory device.

Abstract: 본 발명은 컬러 체크 챠트를 이용한 다중 카메라간 컬러 일치 방법에 관한 것이다. 즉, 본 발명에서는 3차원 정보 복원을 수행하는 영상처리 기법에서 여러 대의 카메라를 사용하여 촬영한 영상을 조합하는 경우 카메라의 특성 또는 촬영 시 조명의 조건에 따라 발생하는 색 차에 대해 각 카메라 별로 기준 컬러 모델과의 관계를 모델링하여 보정을 수행함으로써 다중 카메라간 컬러를 일치시킨다. 이에 따라 여러 대의 카메라를 사용하여 획득한 영상들을 바탕으로 3차원 정보를 복원하는 경우, 카메라마다 다른 컬러 값들을 동일한 값으로 보정하여 2차원 영상들의 정보를 효과적으로 조합하는 것이 가능하다. 또한, 한 대의 카메라를 옮겨가며 촬영하는 것이 불가능한 상황인 동적 물체의 3차원 정보 복원에 유용하다.
카메라, 컬러, 일치, 컬러 체커 챠트Abstract translation: 使用颜色检查图的多视点相机颜色校准方法包括测量从多个相机输入的照片数据的亮度范围; 拍摄每个相机的颜色检查图,并将图表的亮度值调整在每个相机的输入图像的亮度范围内; 通过使用格子图的灰色补丁校正每个相机的亮度; 对由每个相机获得的检查图的颜色值与由颜色检查图提供的标准颜色值之间的关系进行建模; 并且通过建模来校正颜色差异,以校准多个相机之间的颜色。 因此,能够恢复不能通过仅移动一个照相机而拍摄的摄影用移动物体的三维信息。

Abstract: An accuracy measurement method of a 3D graphic model by using an image and a device thereof are provided to compare a reference image that takes a picture of a real thing with a 3D model which is being made, thereby visually notifying a designer of a part from which accuracy and error are created. A camera corrector(102) generates camera parameters by calculating a location, a direction, and an internal factor of a camera, from a reference image. A model synthesizer(104) calculates a location and a direction of a 3D model based on a matching relation between the reference image and 3D graphic model data. A rendering unit(106) performs a rendering process of the 3D graphic model by using the camera parameters, and generates a synthesis image. An image feature extractor(108) extracts features of the synthesis image and the reference image. An error calculator(110) calculates distance and length errors.

Abstract: An apparatus and a method for estimating a focus length of a camera are provided to calculate the fixed focus length of a zoom lens camera from the positions of the corresponding points between images and to verify the reliability of the calculated focus length easily. An image corresponding point position designation member(110) designates the corresponding point positions between the inputted two dimensional image pair. A cost function defining member(120) defines a cost function in order to calculate the focus length for performing the automatic correction of a camera from the corresponding point positions between the designated image pair. A cost function minimizing member(130) calculates the optimum focus length for minimizing the defined cost function. A position and posture calculating member calculates the photographing position and posture of a camera through an algorithm including 5-points, 6-points, 7-points and 8-points by means of the focus length and the corresponding point positions between image pair.
