no. 1 approach

[0042] Recently, movies and the like often use three-dimensional video using three-dimensional image data such as computer graphics (CG). For such three-dimensional video, it is necessary to have good photographic effects and look as if the three-dimensional video was captured by the camera operator. However, in order to generate 3D video that is photographically good and looks as if it was captured by the photographer, 3D translation and rotation information needs to be generated at all times. Therefore, it is difficult to generate a video that appears to be captured by an actual camera operator.

[0043] Meanwhile, a technique has been developed for generating a three-dimensional video showing the inside of a virtual space as if captured by a virtual camera which is an imaginary camera and is arranged in a virtual space created from three-dimensional image data middle.

[0044] In a virtual camera system, rendering a virtual space within the imaging range of the virtual ca...

Embodiment approach 1

[0103] As in the first embodiment, the position and orientation information acquisition unit 201 acquires the position and orientation information from the imaging device 10 . Further, the position and attitude information acquisition unit 201 stores the position and attitude information in the position and attitude information storage unit 202 . Furthermore, the corresponding position specifying unit 203 specifies the current position on the virtual track corresponding to the real space indicated by the position and attitude information. .

[0104] As in the first embodiment, the rotation calculation unit 206 calculates the gravitational force based on the gravitational direction of the imaging device 10 in the real space and the normal direction indicated by the normal vector N at the position in the virtual space corresponding to the imaging device 10 . The amount of rotation that is oriented parallel to the normal direction.

[0105] The posture correction unit 207a and ...

no. 2 approach

[0113] In the first embodiment, the height and attitude are corrected to match the imaging device 10 in the real space with the virtual camera in the virtual space. In the second embodiment, the altitude is corrected without correcting the posture.

[0114] Incidentally, the camera operator can freely determine whether or not to capture video of where in the virtual space. For example, in some cases, a camera operator may capture video of the ground or sky in the virtual space. However, in the first embodiment, considering the correction of the posture, further correction of the posture requires a complicated operation of the camera operator to further tilt the imaging device 10 . Therefore, in the second embodiment, the altitude is corrected without correcting the posture.

[0115] Figure 11 is a diagram showing an example of the movement trajectory of the virtual camera. Figure 12 is a diagram showing an example of the movement trajectory of the virtual camera. Figur...

Abstract

An information processing system (1) is provided with: a first acquisition unit (201) that acquires position and attitude information indicating the position and attitude of a first device (10) in a real space; a specifying unit (203) that specifies, on the basis of the position / attitude information, the position of a virtual imaging device provided in a virtual space associated with the real space; a correction unit (207, 210) that corrects the imaging range (A) of the imaging device in the position and attitude specified by the specifying unit (203) on the basis of the terrain in the virtual space; and a video generation unit (212) that generates a video of the virtual space corresponding to the imaging range (A).

Description

technical field [0001] The present disclosure relates to an information processing system, an information processing method, and a program. Background technique [0002] Three-dimensional video using three-dimensional image data such as computer graphics (CG) has been widely used. For such three-dimensional video, it is necessary to have good photographic effects and look as if the three-dimensional video was captured by the camera operator. However, in 3D video, it is difficult to present the video as if it was captured by the camera operator due to the need to generate 3D translation and rotation information. [0003] Here, techniques have been developed for generating a three-dimensional video showing the interior of a virtual space, the three-dimensional video appearing to be captured by a virtual camera that is an imaginary camera and arranged in a virtual image created from three-dimensional image data in space. Such a virtual camera makes it possible to generate a ...
