Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The present invention is based on the relatively mature laser projection technology at present, because the laser projector has a characteristic: it does not need to focus, and the picture is projected to be clear at any distance in theory, which realizes the display of the object to be projected on any screen in the imaging space. For the image information on the cross-section, the image content of any point seen by the user's eyes is consistent with the image content of the corresponding point of the actual object to be projected, thus providing sufficient visual material for the user to es...

Abstract

The invention discloses a three-dimensional image display method which comprises the following steps of: S1: obtaining the current position information of a screen and determining the current relative coordinates of the screen in the projective space according to the current position information; S2: reading the image data of an object to be projected in the projective space, which is stored in a memory in advance; S3: generating a profile image of the object to be projected in accordance with the image data, and then correcting the profile image in accordance with the current relative coordinates; S4: transmitting the corrected profile image to a projective module so as to erasure that the corrected profile image is imaged on the screen; and S5: returning to the step S1 when the position of the screen is moved in the projective space. When the image display method is used, users can see successive profile images of the object to be projected on the screen through continuously changing the current position of the screen, so that a three-dimensional image of the object to be projected is generated, and the three-dimensional imaging is realized by using a two-dimensional projection instrument.

Description

technical field [0001] The invention relates to the field of image processing and image display, in particular to a three-dimensional image display device and method. Background technique [0002] As we all know, the basic principle of 3D imaging is to allow the viewer to see different pictures with the left and right eyes, the left eye sees the picture that the left eye should see, and the right eye sees the picture that the right eye should see, thus creating a stereoscopic feeling; most of the current products All are based on this principle. [0003] At present, the development of laser projection technology is mature, and laser projectors are already on the market. Among them, laser projectors have a characteristic: they do not need to focus, and theoretically the screen is projected at any distance. In the device, then, when the screen moves freely in the projection space, there is no need to focus, and the images projected in the projection space are all clear. Con...
