In recent years, the country has given the green light to the development of augmented reality technology. Various preferential policies have sprung up such as mushrooms after rain, and augmented reality technology has gradually been applied to all aspects of our lives. In terms of cultural relic protection, the research and protection of ancient murals are undoubtedly not the most difficult. In terms of protection, murals are very fragile, and there are many factors that need to be paid attention to, such as air humidity, temperature, microorganisms, and the shedding of mud layers. In terms of research, the study of frescoes requires a lot of careful observation, but exhaled breath or body temperature that researchers get too close to can have unforeseen consequences. Based on this, the article expounds the composition of the augmented reality technology system. Through image recognition, three-dimensional tracking registration, virtual-real combination, and other technologies, the image obtained by the camera is recognized, and then the environment where the mural is located is a virtual scene through three-dimensional tracking technology. We build and finally use the combination of virtual and real technology to make the ancient murals vividly presented in front of us for our researchers to study more conveniently. The use of Gaussian function, SURF algorithm, FREAK algorithm, RANSAC algorithm, and so on to improve the augmented reality technology system makes the presentation of ancient murals more detailed and realistic. After experiments, we came to the conclusion that the ancient murals processed by augmented reality technology are far more detailed and more complete than the pictures taken by ordinary cameras. Processing ancient frescoes is also far less time-consuming than the existing image processors.

计算机增强现实技术在古代壁画中的应用

近年来，国家为增强现实技术的发展开了绿灯。各种优惠政策如雨后春笋般涌现，增强现实技术逐渐应用到我们生活的方方面面。在文物保护方面，古壁画的研究和保护无疑不是最难的。在保护方面，壁画非常脆弱，需要注意的因素很多，比如空气湿度、温度、微生物、泥层脱落等。在研究方面，壁画的研究需要大量的仔细观察，但研究人员过于接近呼出的呼吸或体温可能会产生无法预料的后果。基于此，文章阐述了增强现实技术系统的组成。通过图像识别、三维跟踪配准、虚实结合等技术，对摄像头获得的图像进行识别，然后通过三维跟踪技术将壁画所在的环境变成一个虚拟场景。我们构建并最终利用虚实结合的技术，将古老的壁画栩栩如生地呈现在我们面前，供我们的研究人员更方便地研究。利用高斯函数、SURF算法、FREAK算法、RANSAC算法等改进增强现实技术体系，使古代壁画的呈现更加细致逼真。实验后，我们得出的结论是，经过增强现实技术处理的古代壁画远比普通相机拍摄的照片更加细致完整。处理古代壁画也比现有的图像处理器耗时少得多。
