摘要
针对现代安防领域高清实时视频监控中目标点过小不易分辨的问题,为满足用户同时掌握场景全局信息与目标点处清晰的局部信息这一需求,提出了一种多屏播放系统的图像局部放大的方案。分析了软件实现的关键技术,建立了全景图像与局部图像的坐标对应关系;提出了一种鼠标定位算法并推导出相关计算公式,完成并实现了图像局部放大模块的软件代码。实验结果表明了该设计方案的准确性和有效性。
Aiming at the problem that the target is too small and illegible in modem high resolution video monitoring, to satisfy the requirement of attaining the whole information and the local intbrmation of the scene simultaneously, a method of zooming in images locally in the multi-screen playing system is proposed. Firstly, the key point of technology is analyzed, and the relationships among the panoramic image and its local parts are constructed. Then, an algorithm of locking the target＇ s position by mouse is proposed and actualized. Lastly, the validity and efficiency of the method is demonstrated by the experimental result.
