要了解3D立体画成像原理，首先必须正确认识立体图像的概念。立体图像通俗的讲就是利用人们两眼视觉差别和光学折射原理在一个平面内使人们可直接看到一幅三维立体画，画中事物既可以凸出于画面之外，也可以深藏其中，活灵活现，栩栩如生，给人们以很强的视觉冲击力。它与平面图像有着本质的区别，

To understand the principle of 3D imaging, we must first understand the concept of stereo image.. Stereo image popular speak is the use of people eyes visual difference and optical refraction principle in a plane so that people can see a picture of a three-dimensional painting, painting things can be convex out of the picture, the deep, vivid, lifelike, give people a strong visual impact. It has the essential difference with the planar image,

平面图像反映了物体上下、左右二维关系，人们看到的平面图也有立体感。这主要是运用光影、虚实、明暗对比来体现的，

The planar images reflect the objects up and down, the left and right relations, and the plane images that people see also have the stereoscopic feeling.. This is mainly the use of light, the actual situation, the contrast of the contrast to reflect,

而真正的3D立体画是模拟人眼看世界的原理，利用光学折射制作出来，它可以使眼睛感观上看到物体的上下、左右、前后三维关系。是真正视觉意义上的立体画。立体图像技术的出现是在图像领域彩色替代黑白后又一次技术革命，也是图像行业发展的未来趋势。在二维平面上模拟三维空间效果一直是人类视觉艺术的焦点问题,尤其是自文艺复兴以来,解决该问题成为艺术进步和艺术史书写的重要标准之一,因此,文艺复兴及其之后的教堂壁画、天顶画、市政大厅、贵族寓所和别墅都成为极好的模拟场所。3D街头地画可看作这一艺术逻辑在当代的重要发展和延伸。所谓3D地画，顾名思义就是将画作展示于地上以求得立体的艺术效果，或直接以地面为载体进行绘画创作。3D地画，则将“艺术效果特殊化”的理念进一步发扬光大，它以室外地面为媒介，利用平面透视的原理，制造出视觉上的虚拟立体效果，令参观者有一种身临其境的感觉。3D地画中的景物立体、细腻、逼真，往往能达到以假乱真的艺术效果。[

And the real 3D stereoscopic painting is the principle of the human eye to see the world, the use of optical refraction produced, it can make the eye feel to see the object on the upper and bottom, left and right, three-dimensional relationship. Is a real visual sense of the three-dimensional painting. The appearance of stereo image technology is a revolution of color in the image field and it is also the future trend of the development of the image industry.. Three dimensional effect in the two-dimensional simulation has been the focus of the human visual arts, especially since the Renaissance, to solve the problem has become one of important standards progress in the arts and art history writing, therefore, after the Renaissance and the frescoes in the chapel, draw the zenith, the municipal hall, aristocratic apartments and villas are an excellent simulation places. 3D street painting can be regarded as the important development and extension of this art logic in the contemporary. The so-called 3D painting, as the name suggests is the painting on the ground to obtain the three-dimensional artistic effect, or directly to the ground for painting creation. 3D painting, artistic effect special "concept further flourish, it to the ground outside as the medium, using planar perspective principle, to create a visual virtual stereo effect, so that visitors have feeling of a kind of be personally on the scene. 3D painting scenery, exquisite, lifelike three-dimensional, can often reach mix the spurious with the genuine artistic effect.
