博物馆展示上的多通道投影融合系统

多通道投影融合是现代展览的重要方式和手段。通过在博物馆展示上设计和实现一个投影融合系统，提出并使用新的三角函数形式的融合函数，论述了运用SURF算法进行特征提取，光流法跟踪的动态图像配准处理方法，分析了投影融合主程序的架构流程，阐述了本方法的特点与利弊，并指出了投影融合向3D 发展的方向。在获取SURF 特征点集和投影变换矩阵后，再进行几何校正，边缘融合，色彩平衡的投影融合三步走流程步骤。经过现场采样评价测试，目测和PSNR数据都说明运行融合效果良好。

Fusion Technology of Multi-Channel Projection in Museum Exhibition

Multi-channel projection fusion is an important solution of modern exhibition. This paper presents the design and implementation of projection fusion system in museum exhibition, which proposes a new trigonometric function as blending function, which proposes SURF algorithm for feature extraction and image registering processing with optical flow algorithm. Main steps and program chart of the projection fusion are analysed, the characteristics, advantages and disadvantages of this method are explained. The direction of the 3D development is pointed out about projection fusion. The procedure gets the SURF feature point sets and the projection transformation matrix of the photo, then three steps for geometric calibration, edge blending, projection color balance are executed. After field sampling and testing, visual inspection and PSNR data illustrate the good effect of fusion.
