摘要
视频监控的在屏交互过程中,需要快速地对交互控件、感兴趣区域、活动标记等图形和图像进行绘制,为避免画面的停滞感,要求图形设备接口能快速进行绘制。为此,提出了一种笔画模型方法。利用DirectX的原始绘制能力,该方法将绘制任务转换成笔画对象,使视频系统在实时运行过程中,只需将已转换的笔画对象的绘制数据提交给DirectX进行渲染和显示即可,降低重复绘制时间,满足系统的快速绘制要求。基于笔画模型方法,开发了一种可快速绘制的图形设备接口。
When the live video surveillance system interacts with users, it needs fast implementation for drawing or painting user controls, interested region picks, activity marks as well as digital images to avoid a frozen display, that requires the graphics device interface modules to draw or paint quickly. We propose a new method named stroke modeling, which takes the advantages of drawing primitives provided by DirectX to transform drawing tasks into stroke objects, enabling the video systems in its run time to fulfill a fast implementation for render or display by submitting the pre-generated stoke objects to the DirectX, cutting off the drawing time dramatically. Following the method, we have developed a graphics device interface module which may be used for quick graphical rendering or drawing.
