Complementary color 3D glasses, also known as chromatic aberration type, are 3D glasses with colored lenses such as red, blue, and red and green. Chromatic aberration can be called color-separation stereoscopic imaging technology, which uses images taken from two different viewing angles to print in the same sub-picture in two different colors. If you look at it with naked eyes, it will show a blurred ghost image. Only through the corresponding red and blue stereo glasses can you see the stereo effect, which is to filter the color with red and blue. The red image passes through the red lens and the blue passes through the blue. Lenses, the different images seen by the two eyes are superimposed in the brain to present a 3D stereoscopic effect.
principle:
Red light passes through the red lens, blue light passes through the blue lens, and the human brain can form a three-dimensional image.
polarized light
Polarized 3D technology is now commonly used in commercial theaters and other high-end applications. The technical method is the same as the shutter type, 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 theaters, etc. Use in venues that require a large audience. The non-flashing type is to use this principle.
principle:
The main reason for the three-dimensional effect is that the pictures seen by the left and right eyes are different, and the positions of the left and right eyes are different, so there will be some differences in the pictures.
When shooting stereoscopic images, two lenses are used, one left and one right. Then the image of the left lens is filtered by a transverse polarizer to obtain transversely polarized light, and the image of the right lens is filtered by a longitudinal polarizer to obtain longitudinally polarized light.
The left eye and the right eye of the three-dimensional glasses are equipped with transverse polarizers and longitudinal polarizers respectively, the transversely polarized light can only pass through the transverse polarizers, and the vertically polarized light can only pass through the longitudinal polarizers. This ensures that the things captured by the left camera can only enter the left eye, and the things captured by the right camera can only enter the right eye, so it is three-dimensional
