Problems solved by technology

[0006] However, because this kind of structure in the known technology requires the use of two projection devices and a synchronization system, the cost is high and it is not easy to carry, and because two projection devices must be used, the alignment of the two projectors needs to be performed before projecting images. , so that the two images projected by the two projection devices at the same time can be played on the same place on the same screen, so that the 3D stereoscopic image can be correctly generated

Embodiment Construction

[0025] see figure 1 , figure 1 It is a schematic diagram of the stereoscopic image projection device 10 of the present invention. A stereoscopic image projection device 10 of the present invention includes an optical signal generator 12 , a filter device 14 , a focusing device 16 and a reflection device 18 . The optical signal generator 12 is used for generating a projection optical signal 13 . The filter device 14 filters the projected light signal 13 to generate a set of polarized light signals 15, the polarized light signals include a first polarized light signal and a second polarized light signal. The focusing device 16 receives the set of polarized light signals 15 to generate a set of focused light signals 17 . In one embodiment, the focusing device 16 may be a focusing mirror. The reflective device 18 receives the set of focused light signals 17 to generate a set of reflected light signals 19. The reflective device 18 includes a base, a plurality of digital micromi...

Abstract

The invention provides a stereoscopic video casting device. It comprises a light signal generator, a light filter, a focus device and a reflector. The light signal generator is used to generate a casting light signal. The light filter filters and castes the light signal to generate a group of polarizing signal. The focus device receives the group of polarizing signal to generate a group of focus light signal. The reflecting device receives the group of focus light signal to generate a group of reflecting light signal.

Description

technical field [0001] The invention relates to an image projection device, in particular to a stereoscopic image projection device. Background technique [0002] People use two eyes to see things, and use the angle between the two eyes to measure the distance and create a three-dimensional effect. Therefore, although the left and right eyes see the same object at the same time, they see different angles. The viewing angles of seeing things are different, so there will be a difference in the viewing angles of the two eyes. The closer the object, the greater the difference between the left and right eyes, and the farther the object is, the smaller the viewing angle difference is. Parallel, the viewing angle difference is almost zero. [0003] The principle of the stereoscopic image in the known technology is to use two cameras to simulate the perspective of two human eyes to shoot at the same time, and then use two projectors to project synchronously, one simulates the image...
