Problems solved by technology

[0003] The defect of the prior art is that the existing computer graphical user interface operates based on a two-dimensional cursor, and the user moves the cursor on the two-dimensional plane with the mouse. A certain interface element on the GUI can be selected
But this kind of 3D mouse still works in the plane two-dimensional scene, only solves the problem of generation and input of displacement information, but does not solve the problem of displaying at different depth levels in the three-dimensional stereoscopic display scene

Embodiment 1

[0032] An embodiment of the present invention provides a cursor processing method in a three-dimensional scene, such as Figure 2A Shown include:

[0033] Step 101, the cursor generating device generates displacement information in three dimensions according to its displacement, and the three dimensions include two dimensions of plane and depth.

[0034] Wherein, the cursor generating device refers to a device for controlling a cursor, such as a mouse. Specifically, the displacement information in two dimensions of the plane can be obtained by controlling the up, down, left, and right movements of the cursor generating device, and the displacement information in the depth dimension can be generated by a depth control unit installed on the cursor generating device. The depth control unit is a unit for controlling the movement of the cursor in the depth direction, such as a scroll wheel, a button or a MEMS device.

[0035] Step 102, adjust the disparity of the cursor correspon...

Embodiment 2

[0053] The embodiment of the present invention provides another cursor processing method in a three-dimensional scene. The difference between this method and method embodiment 1 is that in the step 102, the cursor corresponding to the two eyes is adjusted in real time according to the displacement information. When viewing parallax, the cursor described in method embodiment 1 uses a planar two-dimensional image, while the cursor described in the embodiment of the present invention uses a stereoscopic image that already has parallax, therefore, it can be directly based on the obtained in step 101 The disparity of the stereoscopic image is adjusted by using the displacement information in the depth dimension.

[0054] The method for obtaining the stereoscopic image as the cursor is introduced in detail below, such as Figure 3A Shown include:

[0055] Step 201, obtain a first image by shooting from a first position.

[0056] Among them, such as Figure 3B As shown, the focal ...

Embodiment 3

[0068] The embodiment of the present invention provides another cursor processing method in a three-dimensional scene. This method is similar to method embodiment 2, and both use a stereoscopic image as a cursor. Therefore, the displacement of the depth dimension obtained in step 101 can be directly The information adjusts the disparity of the stereoscopic image. However, the method for acquiring the stereoscopic image as the cursor in the embodiment of the present invention is different from that in the second embodiment.

[0069] The method for obtaining the stereoscopic image as the cursor in the embodiment of the present invention is described in detail below, as Figure 4A Shown include:

[0070] Step 301, perform 3D scene modeling on the cursor used in the 3D scene.

[0071] Such as Figure 4B As shown, a projected model of the scene using a dual camera setup is shown. Where A and B are two points in the scene, O L and O R are the optical centers of the left and ri...

Abstract

The invention relates to a method, a device and a system for processing a cursor. The method for processing the cursor comprises the following steps: displacement information of three dimensionality is generated by a cursor generating device according to the displacement thereof, wherein the three dimensionality includes two plane dimensionality and one depth dimensionality; the optical parallax of the two eye view which corresponds to the cursor is adjusted in real time according to the displacement information; and the two eye view which corresponds to the cursor is output into three-dimensional scene displaying equipment. The system for processing the cursor comprises the cursor generating device and a cursor adjusting device. The cursor in three-dimensional displaying scene can be correspondingly changed according to the displacement information of the depth dimensionality and accordingly can be displayed in different deep levels of the three-dimensional displaying scene, thereby facilitating the operation of the user in the three-dimensional displaying scene and ensuring that the three-dimensional displaying scene has stronger third dimension.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method, device and system for processing a cursor in a three-dimensional scene. Background technique [0002] A stereoscopic view or a 3D view refers to a view with a sense of depth of a scene obtained by independently acquiring images with left and right eyes of a user. The existing 3D scene rendering technology based on stereoscopic views is mainly based on the principle of human binocular parallax, that is, due to the different positions of the two eyes, two images of the same scene but slightly different can be obtained respectively. The camera device acquires two slightly different images of the same scene, which are displayed to the left and right eyes of the person respectively, so that the viewer can obtain a scene with a sense of depth and layering, forming an immersive effect. Bring better user experience. [0003] The defect of the prior art is that: the existing comp...
