Three-dimensional imaging principle

Imaging principle: The distance between human eyes is about 6-7 cm. When they look at an object, they see two slightly different images from different angles. The brain synthesizes these two parallax images to form a three-dimensional sense.

However, the plan we usually see is an image with the same angle, so vision and brain can't extract the true three-dimensional sense of the objects on the screen and can't reflect their three-dimensional relationship.

Stereo images are essentially different from plane images. Stereo images reflect the two-dimensional relationship of objects, and the plane images people see are also three-dimensional. This is mainly reflected in 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 of optical refraction, which can make the eyes see the three-dimensional relationship of the object. It is a stereoscopic painting in the true visual sense.

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

Characteristics of three-dimensional stereogram

A perfect three-dimensional map is composed of two or more layers, which is visually distinct, colorful and has a strong visual impact, making viewers stay in the scene for a long time and leave a deep impression. Cubic painting gives people a real, lifelike and vivid character image and an immersive feeling, which has high artistic appreciation value.

The use of three-dimensional image packaging enterprises, so that the corporate image is more distinct, highlighting 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 imaging industry. I hope it will be helpful for the related picture appreciation and picture making tutorial of falling in love with 3d netizens.

RealPhoto 3D takes advantage of the latest achievements in 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 three-dimensional space of the image. The stereoscopic effect is equivalent to 10 to 30 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, RealPhoto 3D software adopts edge enhancement technology to make the edge of each image block smoothly transition in the depth direction, eliminating the flaky feeling, and it is very easy to make a portrait three-dimensional movie with smooth outline and thick body. Its plane-to-stereo function is equivalent to stereo software shot by stereo camera.

RealPhoto3D makes the stereoscopic relationship clearer, the edge transition more natural, and can shoot a picture that is truly comparable to professional stereoscopic photography. The characters are round enough that their 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.
