为解决无人机高光谱影像图幅较小的问题，通过计算高光谱影像各个波段的峰值信噪比筛选特征波段，基于SIFT算法对筛选出的特征波段提取特征点并对特征点进行匹配，图像拼接过程中利用墨卡托投影纠正图像的变形，同时利用经纬度信息及重投影算法细化高光谱相机参数，从而实现大范围高光谱影像的拼接。为检验拼接高图像的光谱是否
发生畸变，利用光谱角填图、波谱特征拟合分类法及二进制编码３种方法对拼接前后的图像典型地物光谱进行分析。结果表明，拼接前后光谱畸变较小。
In order to solve the problem of small amplitude image of UAV hyperspectral image. In this paper, the feature band is selected by calculating the peak signal-to-noise ratio (SNR) of each band of the hyperspectral image, and then the feature points are extracted and matched to the selected feature band based on the Scale-invariant Feature Transform (SIFT) algorithm. Mercator image is used to correct the image during the image splicing process at the same time, the parameters of hyperspectral camera are refined by using latitude and longitude information together with the reproj algorithm, and finally the hyperspectral image is spliced. In order to test whether the spectrum of the mosaic image is distorted, Spectral Angle Mapping (SAM), Spectral Feature Fitting (SFF) and Binary Encoding (BE) were used to analyze the typical features of the images before and after splicing, the analysis results show that the spectral distortion is small before and after splicing.

增强现实(AUGMENTEDREALITY,AR)技术是在真实的视频图像中叠加虚拟物体,并通过跟踪与注册技术,使用户可以与其进行良好互动的一种技术。随着人们对其研究的不断深入,增强现实技术已经开始应用在生活娱乐、医学、军事与工业生产等众多领域。虚实注册技术是增强现实的核心技术之一,它实时地计算观察者的位置和方向,然后确定虚拟物体在二维图像上的投影位置,最后将虚拟物体实时地叠加到该位置之上,使得虚拟场景能够与真实世界无缝融合。随着计算机视觉技术和计算机图形学的快速发展,基于视觉的虚实注册方法以其设备简单、成本较低及注册精度高等优点
Augmented Reality (AUGMENTEDREALITY, AR) technology is superimposed virtual objects in real video image, and through tracking and registration technology that allows users to interact with their good conduct of a technology. With the deepening of its research, augmented reality technology has been used in many areas began to live entertainment, medical, military and industrial production. Actual situation registered technology is to enhance the reality of one core technology, which calculate in real time the position and direction of the observer, and then determine the two-dimensional image projected location of the virtual object, and finally the virtual object superimposed onto the real-time position so virtual and the real world scene can seamless integration. With the rapid development of computer vision and computer graphics, vision-based registration method and the reality of its equipment is simple, low cost and high precision registration (2016-07-08, Others, 8996KB, 下载5次)
