| 摘 要： | 视频拼接在日常生活中有着广泛的应用。提出了一种基于Linux和Open CV的嵌入式实时视频采集和拼接系统设计方案。该系统采用Tiny4412四核处理器,通过两个摄像头实时采集图像数据,然后结合Open CV库利用改进的算法对两幅具有重叠区域的图像进行拼接处理,包括特征匹配和图像融合处理,生成拼接图像,最后把拼接图像在LCD上实时显示。实验结果表明,采取的算法能够适应多种环境,很好的抑制鬼影,并且拼接速度能够达到实时系统的要求。

| Abstract: | Video stitching has been widely used in our daily life. In this paper, a kind of design scheme of embedded real-time video acquisition and splicing system based on Linux and OpenCV is put forward; The system adopts the Tiny4412 quad-core processors, collects the real-time image data by two cameras, and then uses the OpenCV library with the improved algorithm of two overlapping area of the image to splice images, including the feature matching and image fusion processing, generating the Mosaic image, finally, the splicing images display on the LCD on real-time. The experimental results show that the algorithm adopted in this paper can adapt to various environment, and have good inhibition of ghost, and splicing speed can meet the requirement of real-time system. |
