摘要:
A mixed reality space image generation apparatus for generating a mixed reality space image formed by superimposing virtual space images onto a real space image obtained by capturing a real space, includes an image composition unit (109) which superimposes a virtual space image, which is to be displayed in consideration of occlusion by an object on the real space of the virtual space images, onto the real space image, and an annotation generation unit (108) which further imposes an image to be displayed without considering any occlusion of the virtual space images. In this way, a mixed reality space image which can achieve both natural display and convenient display can be generated.

A mixed reality space image generation method for generating a mixed reality space image formed by superimposing a virtual space image onto a real space image obtained by capturing a real space, includes a first image superimposing step of superimposing a first virtual space image onto a real space image based on an occlusion by a real object, wherein the first virtual space image is an outer appearance of the real object, and obtaining information of location and orientation of the real object. In addition, a second virtual image is set based on the information of location and orientation of the real object, and a second image superimposing step superimposes the second virtual space image onto the superimposed image generated in the first image superimposing step without considering the occlusion, wherein the second virtual space image is an annotation associated with the real object.

An actual-size observation mode in which an observer performs observation by being immersed in a virtual three-dimensional space in an actual size and a reduced-size observation mode in which the observer performs observation by reducing a virtual three-dimensional space computer graphics image are provided. A virtual reality presentation device includes an observation mode setting unit for setting, as an observation mode, the actual-size observation mode or the reduced-size observation mode; a position and orientation information acquisition unit for acquiring position and orientation information of the observer; and a generation unit for generating a computer graphics image from computer graphics data representing the virtual three-dimensional space in accordance with the set observation mode and the position and orientation information.

A virtual reality presentation apparatus (100) has a CPU (101) which controls the overall apparatus, a memory (103) which stores various programs, a memory (104) which stores various data, an HMD (105) as a video display device, and a position and orientation controller (106) having position and orientation sensors (107, 108, 109), which are connected to each other via a bus (102). After a position and orientation required to render a CG scene for one frame are determined, when CG objects are in an interference state immediately before this processing and the difference between the current time and an interference time (128) set upon determining the interference state does not exceed an interference detection skip time (124), CG image generation means (112) generates a CG scene for one frame based on the determined position and orientation without checking if an interference has occurred between the CG objects.

An image-display control apparatus includes a detection unit for detecting a predetermined object from a photographed image, a position calculation unit for obtaining a positional relationship between the predetermined object in the photographed image detected by the detection unit and an object in a virtual image, an image removing unit for removing a predetermined partial image in the object in the virtual image by referring to a result of calculation of the position calculation unit, a synthesis unit for synthesizing the virtual image and the photographed image so that the predetermined object in the photographed image is present at a position of the partial image in the virtual image removed by the image removing unit, and a display control unit for displaying an image obtained as a result of synthesis of the synthesis unit on a display device.
摘要:
The pointing position of a pointing device is measured based on position and orientation information of the pointing device. The pointing position is measured based on the pointing position in a sensed image obtained by sensing the pointing position of the pointing device by an image sensing device, and position and orientation information of the image sensing device. A real pointing position of the pointing device is measured based on these measurement results. A virtual pointing device which points to a virtual image to be combined with a real image is generated using the same reference as that used to measure the real pointing position. A virtual pointing position of the virtual pointing device is measured.
摘要:
An instruction is detected which indicates that a physical object having a fixed plane where the physical object can be moved, and a virtual object rendered so as to be positioned on the plane where the physical object can be moved, are observed as being in a predetermined positional relationship. Then, a difference between a position and orientation value of the virtual object and a position and orientation value of the physical object is acquired at the time when the instruction is detected, so that the difference is used as a correction value to correct the positional difference between the physical object and the virtual object.

An information processing method and an information processing apparatus for preventing a user from experiencing fear in a virtual environment due to the area surrounding their feet being invisible because of CG masking the real space are provided. The information processing method and apparatus acquire the position and posture of the user when generating an image of a virtual reality and combining the image of the virtual reality with an image of real space to present the combined image to the user. When the user is inside a virtual building, the information processing method and apparatus generate objects inside the virtual building and a transparent object and combine the generated objects with an image of real space. By displaying the combined image, the image of real space is displayed at the feet of the user.
