Problems solved by technology

Due to the singleness of the traditional mouse, there is no required disparity map, so the stereoscopic effect cannot be seen on the autostereoscopic display, and it is even more impossible to point to the specified position in the displayed stereoscopic space

Embodiment Construction

[0029] Step 1: Fix 8 CCD cameras on the platform, the camera shooting resolution is 630×350, keep the direction of each optical axis roughly parallel, and make each CCD roughly on the same straight line with roughly equal spacing; use data lines Connect each CCD with the image acquisition card in the PC, and directly connect the 22-inch grating stereoscopic display with the PC.

[0030] Step 2: Preprocess the 8-way disparity map obtained by shooting, adjust the disparity to make it suitable for display on the autostereoscopic display, and then use the stereo image matching technology to mark the disparity of all points with the same name.

[0031] Step 3: Create 8 simulation windows, the size of which is the same as that of a 22-inch grating stereoscopic display, and the resolution is 630×350 of the disparity map. The coordinate system is the same as that of the grating stereoscopic display, and the direction of the coordinate system is as follows image 3shown. The 8 simulat...

Abstract

A three-dimensional mouse adopts computer software programming based on a free three-dimensional display so that the conventional mouse has the three-dimensional function. Firstly a plurality of analog windows which are corresponding with multiple disparity maps adopted by the free three-dimensional display one by one through computer programming, and each disparity map is displayed in the analogwindow with a full-screen mode. Afterwards a conventional mouse is generated in each analog window, then the mouse is moved in the first analog window for aligning to the object to be displayed, and the mice in the rest analog windows are aligned to the object according to the disparity between the points with same name. Finally, the analog windows with disparity are recorded and a new disparity map which contains the mouse is formed; and after the disparity maps are combined and displayed on the free three-dimensional display, the three-dimensional mouse can be realized. According to the invention, a problem that the traditional mouse can only move in a same plane is overcome through generating and recording the disparity information of the mouse so that the three-dimensional mouse can bealigned to a preset spatial position on the free three-dimensional display.

Description

1. Technical field [0001] The invention belongs to the field of information technology, in particular to a three-dimensional mouse. 2. Background technology [0002] As we all know, the real world is a real three-dimensional world, and most of the existing display devices can only display two-dimensional information, which cannot give people a sense of depth. Various attempts have been made to make displayed scenes and objects have a sense of depth (ie, 3D). The three-dimensional display system based on the principle of binocular parallax stereoscopic imaging of human eyes is one of them. It makes the left and right parallax images enter people's left and right eyes respectively. The viewer has a three-dimensional stereoscopic sensation. The grating-type three-dimensional autostereoscopic display developed by using this principle is to present the left and right parallax images to the eyes of the human eye through the spectroscopic effect of the cylindrical or slit grating...
