Customers from many engineering channels have complained to me that the brightness of the projector is not enough and the parameters are not high, which can not meet the needs of on-site use
Here to share with you how to build a polarized 3D dual projection system At present, in the market, the civil 3D projection scheme is divided into single machine scheme and double machine scheme
The single machine scheme belongs to active 3D technology and uses only one projector; The dual computer scheme belongs to passive 3D technology (polarized 3D technology)
The cost of 3D glasses and other auxiliary equipment is low, but the requirements for output equipment (requiring dual projectors and metal curtain) are high Two identical projectors are required to project left eye and right eye images respectively, without loss in brightness, contrast and saturation
In addition, they are equipped with polarizer, polarizing 3D decoding converter and polarizing 3D glasses to project three-dimensional 3D effects based on the principle that the left and right eyes receive different signals
Therefore, they have become the first choice for many 3D projection lovers Polarized 3D technology is widely used in commercial cinemas and other high-end applications
It is similar to the shutter type in terms of technology
The difference is passive reception, so it is also called passive 3D technology
The cost of auxiliary equipment is low, but the requirements for output equipment are high, so it is very suitable for commercial cinemas and other places that need a large audience Polarized 3D dual projection system realizes polarized 3D projection through two projectors
These two projectors must use the same model to ensure that the display effect seen by the left eye and the right eye is exactly the same
At the same time, the dual computer scheme has high requirements for debugging, and the two pictures, pixels and pixels * completely coincide, while the single computer scheme does not have this problem Cooperate with the polarizing 3D decoding converter, one signal in and two signals out, output the left and right eye signal format, and then the brain accepts it to form a three-dimensional 3D effect To see the three-dimensional effect, it is necessary to install a polarizer in front of each projector lens, which acts as a polarizer
The light emitted from the two projectors becomes polarized light after passing through the polarizer The polarization directions of the polarizers are perpendicular to each other, so the polarization directions of the two beams of polarized light are also perpendicular to each other
These two beams of polarized light are projected onto the screen and then reflected to the audience, and the direction of polarized light does not change
When the audience watches with the above polarized glasses, each eye only sees the corresponding polarized light image, that is, the left eye can only see the picture reflected by the left machine, and the right eye can only see the picture reflected by the right machine
In this way, it will produce a three-dimensional feeling like direct viewing The polarized 3D dual projection system requires the use of metal screens with high gain and large viewing angle, because the ordinary projection screen will change the polarized light, greatly weakening the three-dimensional effect, and avoiding the problem of insufficient brightness of the single-machine 3D scheme
However, the use of metal screen also has disadvantages
When appreciating ordinary 2D images, the high gain metal screen may affect the color and contrast of the picture The left eye and right eye of polarized 3D glasses are equipped with transverse polarizer and longitudinal polarizer respectively
The transverse polarized light can only pass through the transverse polarizer and the longitudinal polarized light can only pass through the longitudinal polarizer, so that you can see the three-dimensional picture Since polarized 3D glasses do not need to be embedded into the receiver like active 3D glasses, the cost is very low
At the same time, the weight of glasses is very light, which makes them more comfortable to wear during long-term viewing without charging This scheme does not need to link computer equipment
It only needs the player, hard disk and polarizing decoding converter
One signal comes in and is divided into two signals to form the left and right signal format
The two cameras respectively show the images of the left eye and the right eye, and then receive them respectively through polarizing glasses
The 3D dual projection system basically solves the problem of insufficient 3D brightness of a single machine Due to the large attenuation of brightness by stand-alone 3D technology, this technology can only be played on small screens, but can not be realized for screens more than 15 meters The advantage of using polarized 3D dual projection system is to solve the disadvantage of insufficient brightness
3D stereoscopic sense is stronger, which can provide larger light output, larger screen, more realistic color and more perfect detail performance
Due to the use of polarized glasses, the weight of glasses is greatly reduced, and it is more comfortable to wear during long-term viewing
The disadvantage is that the position adjustment of the two projectors is troublesome and the cost of the two projectors is high
