Problems solved by technology

Plane representation cannot provide a full perspective, overall, complete view reflecting the internal organization and structural characteristics of materials or structures
There is also a method of sampling in three directions and directly stacking to express the three-dimensional tissue structure. Because the obtained image does not conform to the viewing angle habit of human eyes, it is easy to cause observers to misunderstand the internal organizational structure expressed by this image. Therefore, it cannot be widely used in engineering and research

Embodiment Construction

[0025] Take the plane pictures of the same magnification or reduction ratio on the three orthogonal sections of the surface or internal section of the metal material to be expressed, and use an electron microscope to magnify 2000 times, and the three angles of 90 degrees to each other ( (i.e., orthogonal) to independently sample in the direction, and take pictures after surface treatment, or select three mutually perpendicular surfaces on a sample, and take pictures separately after surface treatment, such as Figure 1 ~ Figure 3 As shown; input the above-mentioned plane picture into the computer; select one of the three directions, such as the X direction, as the front view direction; one such as the Y direction, as the top view direction; the third such as the Z direction, as the side view direction (such as the right view direction) ), use Photoshop to synthesize quasi-three-dimensional stereoscopic images through selection, cropping, rotation, compression and other processe...

Abstract

The present invention relates to a quasi-three-dimensional image construction method of an internal construction of a material, comprising the following steps: taking a sample; determining viewing planes; shooting a plane photo or image for planes respectively; after inputting the photo or the image into a computer, utilizing a common image processing software to synthesize the quasi-three-dimensional image according to a real position relationship of the plane photo and a perspective principle. Compared with the prior art, the quasi-three-dimensional image construction method provided by the invention has the advantages of lifelike three-dimensional effect, and can reflect actually the information such as an internal constructional feature, a spatial relationship between the internal construction units and a distribution mode in the sample and so on, which can be applied to a three-dimensional characteristic of a macrostructure and a microstructure of various materials such as a metal, a pottery, a macromolecule material, a stone material, the bamboo, a wood and other engineering materials, and used in the fields of material inspection, evaluation, advertisement propaganda the product sample, etc.

Description

technical field [0001] The invention relates to a method for processing a plane picture, in particular to a method for forming a quasi-three-dimensional stereoscopic image of the internal tissue structure of a material by using the plane picture. Background technique [0002] Conventional technical graphics, such as internal micro- and macro-organization diagrams of materials or structures, are color or black-and-white plane graphics. The internal structure of a material or structure is different in the three directions of X, Y, and Z. Even if it is an isotropic material or structure, there is a need to clearly express the organization of the three directions at the same time. For structural descriptions in different directions, people often use three unrelated pictures to represent. Although there is a way to put the three pictures together, it lacks a three-dimensional sense and does not conform to people's three-dimensional observation habits, so it cannot truly express ...
