基于CUDA的全景视频实时监控系统设计

Design of CUDA-based panoramic video real-time monitoring system

针对传统监控方案人机交互感受较差、存在视觉盲区等缺陷,以及传统全景视频拼接技术难以实现实时性输出等问题,设计了一种基于CUDA编译模型的全景视频实时监控系统。通过初始化阶段计算出每一路相机获取的图像的像素点位置变换关系并保存在映射表中,在重叠区域寻找一条最佳接缝线并生成接缝线掩码图,利用CUDA编译模型实现全景图像的实时处理。实验结果表明,该监控系统具有良好的视觉性,并达到了全景视频实时性输出的工程要求。

Aiming at the shortcomings of traditional monitoring schemes such as poor human-computer interaction experience and visual blind area,as well as the difficulty in realizing real-time output of traditional panoramic video stitching technology,a real-time panoramic video monitoring system based on CUDA compilation model was designed.At the initialization stage,the pixel position transformation relationship of images obtained by each camera was calculated and saved in the mapping table.An optimal seam line was found in the overlapping area and the seam line mask was generated.The real-time processing of panoramic images was realized by CUDA compilation model.Experimental results show that the monitoring system has good visual performance and meets the engineering requirements of real-time output of panoramic video.
