【摘要】：增强现实AR(Augmented Reality)是虚拟现实领域中的一个前沿研究分支。它是一种可以把真实环境和虚拟物品相结合的技术,通过三维图形技术和视觉跟踪的方法,把虚拟物体与现实景象联系起来,让我们在真实的世界中去体验虚拟的物体,获得一种类似于和真实物体接触的感受。事实证明,A R技术具有互动良好、方便实用、感受真实等特点,可以在液晶屏、电脑、手机上广泛使用。广告商利用这一技术,不仅能更好的宣传自己的产品,也能加深与客户之间的互动交流。本文主要研究了在带有摄像头的手持设备上如何运用这一技术,怎样把广告植入到这一技术中。具体有以下几点： 1、增强现实与跟踪标志物：我们可以用手机上带有的摄像头,获取需要的视频图像,然后努力建设一种映射,把物理环境中的特定物体和虚拟物体联系起来。这就需要引入PC平台和手机平台,我们采用引入可视码的办法来建立这种联系。有了可视码,就可以跟踪标志物了。本文采用的是一种比较先进的彩色可视码。 2、以本文提出的彩色可视码标志为基础,设计一种三维的增强现实算法。建立一种虚拟内容和物理世界融合的效果。和传统增强现实相比,在手持设备上操作难度更加大,手持设备由于体积小等缘故,图像分辨率不高,计算能力也比较低。所以,我们的优势在搜索效率、识别的精准性和跟踪的稳定性方面。 3、在手机上,有很多种不同三维图形的显示接口,应该采取什么样的平台,取决于具体的需要。本文详细探讨了通过使用VRML绘制手机上三维图形和使用OpenGL ES来实现3D效果的开发。 4、对前文所说的理论进行具体的实验,如跟踪速度、准确率、编码容量等。再根据实验的结构,探索它实现的可能性,并设计它的实现方式。 5、分析了增强现实技术在广告运用中的背景和前景,并举出已经运用的成功实例,比如名片AR、室内场景AR。
[Abstract]:Augmented reality (AR) is a frontier research branch in the field of virtual reality. It is a technology that can combine real environment with virtual objects. By means of 3D graphics and visual tracking, we can connect virtual objects with reality, and let us experience virtual objects in the real world. Get a feeling similar to being in contact with real objects. It has been proved that the technology can be widely used in LCD screen, computer and mobile phone because of its good interaction, convenience and practicality. Advertisers use this technology not only to better promote their products, but also to deepen interaction with customers. This paper mainly studies how to apply this technology to handheld devices with camera and how to implant advertisement into this technology. There are the following: 1. Augmented reality and tracking markers: we can use the camera on our mobile phone to get the video images we need, and then try to build a mapping. Associate a specific object in a physical environment with a virtual object. This requires the introduction of PC and mobile platforms, we use the introduction of visual code to establish this connection. With a visual code, you can track the marker. In this paper, a more advanced color visual code is used. 2. Based on the color visual code flag proposed in this paper, a 3D augmented reality algorithm is designed. To establish a virtual content and physical world fusion effect. Compared with the traditional augmented reality, it is more difficult to operate on the handheld devices. Because of the small size, the image resolution is not high and the computing power is relatively low. Therefore, our advantages are in terms of search efficiency, accuracy of identification and stability of tracking. 3. On mobile phones, there are many different 3D graphics display interfaces, and what kind of platform should be adopted depends on the specific needs. This paper discusses in detail how to use VRML to draw 3D graphics on mobile phone and OpenGL es to realize the development of 3D effect. 4. Experiments are carried out on the theory mentioned above, such as tracking speed, accuracy, coding capacity and so on. Then, according to the structure of the experiment, it explores the possibility of its realization, and designs its implementation mode. 5. The background and prospect of the application of augmented reality technology in advertising are analyzed, and the successful examples are given. For example, business card ARs, indoor scenes ARs.
