Eyes side by side about 6? 7cm, so the image seen by the left eye is slightly different from that seen by the right eye. This difference is called. Parallax? . It is used to explain binocular parallax, determine the distance between objects and produce stereoscopic vision. Let's talk about the human eye first. The distance between human eyes is about 6 cm. In other words, when you look at an object, two eyes see it from the left and right angles respectively. The left eye will see the left side of the object and the right eye will see the right side. When the object seen with both eyes is imaged in the retina, the left and right impressions will be combined to achieve the final three-dimensional effect. Get a three-dimensional effect? Visual displacement? .
If you want to shoot a 3D movie, use two cameras to simulate the parallax between the left eye and the right eye, shoot two videos respectively, and then display the two videos on the screen at the same time. The left eye can only see the left eye image and the right eye image. When the last two images are superimposed on the brain, you can see a three-dimensional image. This is called a 3D image.
/kloc-In photography in the early 20th century, people used two cameras with the same performance and parameters to simulate a person's left eye and right eye, and took two slightly different photos at the same time. Proprietary framing equipment, like crosshairs or binoculars, allows two left eyes and right eyes to see two photos side by side and play them? Parallax? To simulate stereoscopic vision. With the wide application of stereoscopic display technology in TV broadcasting, video games, medical care and education, stereoscopic display has developed from movie screen to TV terminal, computer terminal, smart phone terminal and tablet computer terminal.
