Imaging principle of 3D stereogram

imaging principle: when people's eyes are about 6-7 cm apart, they see two slightly different images from different angles, and the brain synthesizes these two parallax images to form a stereoscopic feeling.

But we usually see a plan, because it is an image with the same angle, so vision and brain can't extract the real three-dimensional sense of the object on the picture and can't reflect its three-dimensional relationship.

There are essential differences between stereoscopic images and plane images. Plane images reflect the two-dimensional relationship between objects up and down, left and right, and the plane images people see also have a three-dimensional effect. This is mainly reflected by the use of light and shadow, reality and contrast between light and shade.

The real stereoscopic painting is the principle of simulating people's eyes to see the world. It is made by optical refraction, which can make the eyes see the three-dimensional relationship of objects up and down, left and right, front and back. It is a stereoscopic painting in the true visual sense.

At present, people use advanced digital synthesis technology to make stereoscopic images. They only need to select clear photos or negatives and scan them into the computer. They can directly use professional drawing software to make drawings and digital processing in the computer, print them out with a high-precision color jet printer, and then mount them with a cold mounting machine.

Features of p>3D stereogram

A perfect stereogram is composed of two or more layers, which is visually distinct and colorful, and has a strong visual impact, which makes viewers stay in the scene for a long time and leave a deep impression. Stereograph gives people a real, lifelike, vivid character, immersive feeling and high artistic appreciation value.

packaging enterprises with stereoscopic images will make the corporate image more vivid and highlight the strength and grade of enterprises. Increase influence! It can highlight the high quality and high grade of products. You can also make colorful and layered three-dimensional wedding dresses and photos, which is one of the latest selling points in the current imaging industry. I hope it will be helpful to fall in love with 3d netizens' related picture appreciation and picture making tutorials.

RealPhoto 3D makes use of the latest achievements in the field of graphics and images, such as pattern recognition, mathematical morphology and 3D image technology. It can transform a plane image into a completely real 3D image, and can reproduce the real stereoscopic space of the image. The stereoscopic effect is equivalent to that of a professional stereo camera with 1 to 3 lenses, and there is no non-parallax interference, which greatly expands the application of stereoscopic images in the advertising field.

according to the design requirements, the edge of each image block is smoothly transitioned in the depth direction by using the edge enhancement technology in RealPhoto3D software, which eliminates the flakiness feeling and makes it very easy to make a portrait stereoscopic film with smooth outline and thick body. Its plane-to-stereoscopic function is equivalent to the stereoscopic software shot by a stereoscopic camera.

RealPhoto3D makes the stereoscopic relationship clearer, the edge transition more natural, and it can produce pictures that are truly comparable to professional stereoscopic photography. The characters have enough roundness and the limbs can stretch freely in space. This technology is widely used, including stereo photo, three-dimensional decorative painting, three-dimensional computer portrait, three-dimensional printing and three-dimensional advertising design.
