Problems solved by technology

However, the above-mentioned image changes are all set in advance by related equipment such as 3D displays or 3D movies, that is to say, the viewer sees the images of the position, size, angle, etc. The changes are all displayed by the 3D display at a fixed position in front of the viewer. The viewer must use devices such as joysticks or sensory gloves to operate them, and cannot directly interact with the virtual objects displayed in front of him. Still not intuitive enough for the viewer

Embodiment Construction

[0047] What surprises viewers most about 3D stereoscopic images is that the objects in the images often appear to be floating in front of the eyes and within reach. Unfortunately, the current technology is still unable to provide viewers with direct hand interaction with virtual objects in 3D stereoscopic images. interactive. In this regard, the present invention defines an operation area around the virtual object according to the depth of field between the virtual object in the three-dimensional image and the screen, so that the user can manipulate the virtual object by performing gestures in the operation area, and then Interact with virtual objects. This virtual object can perform effects such as moving, rotating, zooming in or zooming out according to the gestures of the viewer. In order to achieve the above effects and make the content of the present invention more clear, the following examples are listed as examples in which the present invention can indeed be implement...

Abstract

The invention discloses a control method and a control system for a three-dimensional virtual object and a processing device for the three-dimensional virtual object. The method comprises the following steps of: displaying a three-dimensional image on a screen, and forming a depth of field between a virtual object in the three-dimensional image and the screen; then acquiring an image in front of the screen, and detecting a gesture in the image; judging whether the gesture is close to the virtual object; and if the gesture is close to the virtual object, performing operation corresponding to the gesture to the virtual object. Therefore, a viewer who views the three-dimensional image can interact with the virtual object through the gesture. The control method and the control system can be widely applied to the fields of medical science, engineering, entertainment, education training and the like, so that the convenience in operation of the device is improved.

Description

technical field [0001] The present invention relates to a control method, system and device of a virtual object, in particular to a control method, a control system and a processing device of a three-dimensional (3D) virtual object. Background technique [0002] With the advancement of technology, 3D images are the latest development trend after high definition (HD) images. With the rapid rise of 3D display-related industries, 3D movies and 3D displays may be popularized in everyone's home in the future, and even images from mobile phones or game consoles can be presented in 3D. [0003] 3D images include images that are provided to the left eye and right eye of human beings respectively. When the left and right eye images are presented on the retinas of the two eyes, there will be a certain parallax (parallax), and after being transmitted to the cerebral cortex, it will be transmitted by the cerebral cortex center. Merging them into a single object image with layers and de...
