Description
发明名称：模拟图像成像方法和模拟眼镜 Title of Invention: Analog Image Imaging Method and Simulated Glasses
技术领域 Technical field
[0001] 本发明属于电子技术领域， 尤其是涉及一种模拟图像成像方法和模拟眼镜。 [0001] The present invention belongs to the field of electronic technologies, and in particular, to a simulated image imaging method and simulated glasses.
背景技术 Background technique
[0002] 人的大脑或感觉器官会因为向眼镜输入的不同的信号而产生不同的错觉， 如戴 上墨镜使人感觉天气变暗， 而三维成像技术又使人感觉在同一平面上的画面又 凹凸感。 [0002] The human brain or sensory organs may have different illusions due to different signals input to the glasses, such as wearing sunglasses to make people feel the weather darkening, and the three-dimensional imaging technology makes people feel the same plane Concavity.
[0003] 同吋， 在现在的成像技术中， 已经实现了三维模拟成像， 所谓三维模拟成像是 指在计算机上构建一个立体图画。 该技术已经发展成熟， 并广泛应用于各种工 业设计中。 [0003] At the same time, in the current imaging technology, three-dimensional analog imaging has been realized, and the so-called three-dimensional analog imaging refers to constructing a stereo picture on a computer. This technology has matured and is widely used in various industrial designs.
[0004] 于此同时， 如电影中的特效一般， 不同图像之间的动态叠加同样也非常成熟。 [0004] At the same time, as in special effects in movies, the dynamic superposition between different images is also very mature.
比如要表现一个宇宙飞船从地王大厦前面缓缓飞过吋， 将二者的模拟模型相叠 加， 并掩盖地王大厦中与宇宙飞船重合的部分即可。 反之， 如果要表现一个宇 宙飞船从地王大厦后面缓缓飞过时， 则需要将二者的模拟模型相叠加， 并掩盖 宇宙飞船中与地王大厦重合的部分。 For example, to express a spaceship flying slowly from the front of the Diwang Building, stack the simulation models of the two, and cover the part of the Diwang Building that coincides with the spacecraft. On the other hand, if you want to express a spacecraft flying slowly from behind the King's Building, you need to superimpose the simulation models of the two and cover up the part of the spacecraft that coincides with the Diwang Building.
