随着移动设备的普及,视频监控已拓展到智能移动设备领域,使得传统的视频监控系统脱离了时间和空间的限制。通过对现有的视频监控系统中预警区域划分方法的分析,结合移动视频监控系统的特点,提出2种适用于移动视频监控的预警区域划分方法。九宫格预警区域划分方法,利用布局文件实现,用M行N列的单元格填充整个监控画面,选择合适的单元格,即可确定预警区域。曲线拟合式预警区域划分方法,选取N个离散点,通过贝塞尔曲线分段拟合或者最小二乘法整体拟合形成封闭区域,监控画面内,封闭区域内部或者外部即为预警区域。这2种方法操作简便,易于实现,有效地提高了图像传输速率。
隨著移動設備的普及,視頻鑑控已拓展到智能移動設備領域,使得傳統的視頻鑑控繫統脫離瞭時間和空間的限製。通過對現有的視頻鑑控繫統中預警區域劃分方法的分析,結閤移動視頻鑑控繫統的特點,提齣2種適用于移動視頻鑑控的預警區域劃分方法。九宮格預警區域劃分方法,利用佈跼文件實現,用M行N列的單元格填充整箇鑑控畫麵,選擇閤適的單元格,即可確定預警區域。麯線擬閤式預警區域劃分方法,選取N箇離散點,通過貝塞爾麯線分段擬閤或者最小二乘法整體擬閤形成封閉區域,鑑控畫麵內,封閉區域內部或者外部即為預警區域。這2種方法操作簡便,易于實現,有效地提高瞭圖像傳輸速率。

Abstrca t:With the popularity of mobile devices, video monitoring has been extended to the field of smart mobile devices, beyond the limit of space and time.In this paper, two kinds of early-warning regional patition methods suitable for mobile video monitoring are proposed.It combines the analysis of the existing warning area patition method for video monitoring system and the characteristics of mobile video monitoring system.The nine-grid early-warning areas partition method is achieved by layout files.The entire monitor screen was filled with M rows and N columns of cells.The early-warning zone is determined by selecting appropriate cells.N discrete points are selected using the curve fitting warning region division method.Then, a closed region is formed using Bessel curve fitting method or least squares fitting.In the video monitor screen, either internal or external closed region is the warning area.These two methods, which are simple and easy to be implemented, improve the transmission speed efficiently.
