    • A system includes a video sensing device, a computer processor coupled to the video sensing device, and a display unit coupled to the computer processor. The system is configured to display on the display unit a footprint of the video sensing device in an environment, receive input from a user that directly alters the footprint of the video sensing device, calculate a change in one or more of a pan, a tilt, and a zoom of the video sensing device as a function of the direct alteration of the footprint, alter one or more of the pan, the tilt, and the zoom of the video sensing device as a function of the calculations, and display a field of view of the video sensing device on the display unit as a function of the altered pan, tilt, and zoom of the video sensing device.
    • 系统包括视频感测设备,耦合到视频感测设备的计算机处理器以及耦合到计算机处理器的显示单元。 该系统被配置为在显示单元上显示视频感测设备在环境中的占地面积,从用户接收直接改变视频感测设备的占地面积的输入,计算一个或多个平移,倾斜 以及作为直接改变占地面积的函数的视频感测设备的变焦,改变作为计算的函数的视频感测设备的平移,倾斜和变焦中的一个或多个,并且显示一个字段 视觉感测设备在视频传感设备上的改变的平移,倾斜和变焦的功能。

    • A system for automatically determining the placement of cameras receives data relating to a plurality of polygons. T polygons represent one or more of a surveillance area, a non-surveillance area, a blank area, and an obstacle. The system selects one or more initial cameras, including one or more initial camera positions, initial camera orientations, and initial camera features, wherein the initial camera positions and the initial camera orientations cause one or more fields of view of the initial cameras to cover at least a part of the surveillance area. The system alters one or more of a number of cameras, an orientation of the cameras, a location of the cameras, a type of the cameras, and a crossover of two or more cameras. The system uses a fitness function to evaluate all of the cameras and all of the camera positions, and selects one or more cameras and the locations and orientations of the one or more cameras as a function of the fitness function.
    • 用于自动确定相机放置的系统接收与多个多边形有关的数据。 T多边形表示监视区域,非监视区域,空白区域和障碍物中的一个或多个。 该系统选择一个或多个初始照相机,包括一个或多个初始照相机位置,初始照相机方向和初始照相机特征,其中初始照相机位置和初始照相机方向使初始照相机的一个或多个视野覆盖在 至少部分监视区域。 该系统改变多个相机中的一个或多个,照相机的方向,相机的位置,相机的类型以及两个或更多个相机的交叉。 该系统使用适应度函数来评估所有摄像机和所有摄像机位置,并根据适应度函数选择一个或多个照相机以及一个或多个照相机的位置和取向。
