Problems solved by technology

[0005] However, because the user cannot grasp the shooting of the 3D image, the 3D effect is often caused by too large or too small parallax, or the user feels uncomfortable when watching. The projection technology that automatically adjusts the dot pitch of each pixel of the 3D image makes the presented 3D image suitable for human eyes, which will be of great help to improve the comfort of users when viewing 3D images

Embodiment Construction

[0024] figure 1 A structural diagram of a projection element according to an embodiment of the invention is shown. As shown in the figure, the projection element 101 according to an embodiment of the present invention includes a sensor 103 , a processor 105 , and an output lens 107 . The sensor 103 is used to sense the distance from a projection screen 111, and then transmits the sensing result to the processor 105; the processor 105 is used to obtain a parallax information (not shown) according to the above-mentioned distance from the projection screen 111 , and generate a 3D output image 113 according to the acquired disparity information and an input signal 109 . The output lens 25 is used to project the 3D output image 113 generated by the processor 105 onto the projection screen 111 . According to an embodiment of the present invention, the sensor 103 can be a range finder, an infrared sensor, a laser sensor or a camera.

Abstract

The invention relates to a projection element and a projecting method. The projection element comprises a sensor, a processor and an output lens, wherein the sensor is used for sensing a distance with a projecting curtain; the processor is used for acquiring a piece of parallax information according to the distance and generating a three-dimensional output image according to the parallax information and an input signal; and the output lens is used for projecting the three-dimensional output image to the projecting curtain. The projecting element and the projection method disclosed by the invention can ensure that a user can view a most comfortable 3D(three-dimensional) output image, and are more applicable to actual demands of the user.

Description

technical field [0001] The present invention mainly relates to the projection technology of the projection element, in particular to the projection technology for automatically adjusting the parallax of the three-dimensional image according to the distance. Background technique [0002] In recent years, with the development of computer graphics technology, the application of scientific visualization (scientific visualization) has also risen rapidly. Compared with the traditional two-dimensional (2D) representation, scientific visualization Using graphics, colors, and images to present the content of three-dimensional (3D) data makes it easier to impress and understand at a glance. [0003] 3D display technology can be mainly divided into two types that require (Glasses) and non-Glasses (Non-Glasses) with special glasses. Currently, most of the 3D projectors launched on the market still use the technology that requires glasses. The reason why 3D display technology can achiev...
