摘要： There is disclosed a mixed reality presentation apparatus which generates and displays a three-dimensional virtual image on a see-through display device so as to allow a plurality of players to play a multi-player game in a mixed reality environment. The apparatus has a CCD camera for detecting the mallet positions of the plurality of players, and a sensor for detecting the view point position of each player in the environment of the multi-player game. The apparatus generates a three-dimensional virtual image that represents a game result of the multi-player game that has progressed in accordance with changes in mallet position detected by the CCD camera and is viewed from the view point position of each player detected by the sensor, and outputs the generated image to the corresponding see-through display device. The apparatus determines the motion of each player by detecting infrared rays output from the corresponding mallet on the basis of an image captured by the CCD camera. The view point position detected by the sensor is corrected by specifying the marker in an image obtained by a camera attached to the head of each player, and comparing the marker position in that image with an actual marker position.

摘要： A virtual space using a geometric model for forming a virtual environment is input, nongeometric model object expression data based on a multi-viewpoint image is acquired, geometric information is added to the acquired nongeometric model object expression data, and the nongeometric model object expression data is used as an object arranged or operated in the virtual space using the added geometric information or automatically moving in the space. The same effect as that obtained when the shape data of an object having a very complex shape is generated or reproduced can be easily obtained without generating or reproducing the shape data. In addition, the entire virtual space can be generated without holding an enormous amount of light space data, so that the object can be operated in the three-dimensional space.

摘要： Each two adjacent images of multi-viewpoint images are interpolated by detecting corresponding pixels and generating an interpolated image in accordance with the correspondence among pixels. The interpolated image is generated in such a manner that an epipolar plane is generated by juxtaposing corresponding lines of the multi-viewpoint image, straight lines are detected from the epipolar plane image, and the intersecting points between interpolated lines and the detected straight lines are detected as interpolated pixels. In this case, as for a point for which a straight line cannot be detected, a straight line passing the point is estimated, thereby generating an interpolated pixel. When a plurality of straight lines are detected for a pixel of interest, a priority level is assigned to the pixel of interest in correspondence with the number of detected straight lines. When the priority level is smaller than that of another pixel through which the detected straight line passes, the straight line is ignored, and an interpolated pixel is not generated.
