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.

A system for guidance and navigation in a building. For example, the system may determine a route for egress or rescue of one or more people from a building with a hazardous condition. The system may process the route into waypoints and segments developed within a set of constraint rules. Semantic information about the building may be associated with the waypoints and/or segments. The waypoints and segments may be processed into navigation commands. The navigation commands may be formed in natural language from sentence templates. The system may additionally have 3D beacon audio to assist in guidance and navigation of the one or more people in the building.
摘要:
A method for enhanced location sensing based on topology constraints. A potential position value and a corresponding probability value with respect to an observed position data of an object within a structure can be calculated utilizing a normal probability distribution function. Thereafter, an optimal route between adjacent observed time periods may be calculated utilizing a heuristic search algorithm. The potential position value and the optimal route can be calculated by accessing a pre-installed topology data associated with the structure. An optimization problem can then be solved to refine the observed position data. The position between a pair of observed time periods can be interpolated and the position of the object before a next observed time can be predicted by interpolation based on the spatial constraints.

Devices, methods, and systems for generating an operational user interface for a building management system are described herein. One method includes generating a widget using geometrical information associated with a building information modeling object and relationship information associated with the building information modeling object, assigning a state variable to the widget by analyzing properties of the building information modeling object or an ontology definition of the building information modeling object, associating the state variable with a point from the building operation system by mapping the point to the state variable, and changing the state variable based on input received from a user.

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 displays on the display unit a field of view of the video sensing device, and displays a three dimensional widget within the field of view. The widget includes one or more features for altering one or more of a location or size of the widget, thereby altering an area in the field of view covered by the widget. The system then alters one or more of a pan, a tilt, and a zoom of the video sensing device as a function of the alteration of the location or size of the widget, thereby altering the field of view of the video sensing device.

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.
