Definitions
- the present invention relates generally to digital images, and more particularly, to the viewing of digital images.
- the scale information on the drawing is not computer recognizable when the digital version of the paper drawing is viewed on a monitor or display device.
- the digital image of the drawing is typically captured as a digital image having a certain pixel by pixel dimension with no direct or easy means to establish a relationship to the scale information contained on the original drawing.
- the scale that appears on the document (e.g., one eighth inch equals one foot, etc.) will be incorrect when an electronic depiction of the document is displayed on a computer monitor.
- the original physical size of a paper image has no direct correlation to the pixel dimensions of a computer monitor.
- a 20 inch wide monitor can only display an image as twenty inches wide if viewing the whole image and a twenty-five inch wide monitor can only display an image as twenty-five inches wide if viewing the whole image.
- neither monitor would be able to display the whole image as it originally appeared, that is, as a forty inch wide image.
- event information regarding buildings can be displayed with the digital drawing of buildings.
- buildings can be provided with various alarm systems.
- U.S. patent application Ser. No. 10/434,390 discloses a method of displaying event information from a building system where the event is a non-normal condition generated within a building system. Information regarding the building is displayed on a display portion. The displayed information is selectable and changeable by a user.
- An alarm graphic can also be displayed which relates to a non-normal condition in a building.
- a user may elect to show a floor plan, which discloses the status of fire system alarm generating devices.
- this graphic may be displayed, the user is unaware of the accurate to- scale spatial relationships that exist between people in the building, the non-normal condition, and the building's structural characteristics.
- a responder assets management system is disclosed in U.S. patent application Ser. No. 10/038,572.
- the disclosed system utilizes information available to responders including emergency response personnel including local weather, national weather, and links to other information.
- the system also provides virtual walkthrough capability of a building or facility. However, while providing this virtual walkthrough, there is no ability for the user to scale and zoom to determine exact spatial relationships.
- U.S. patent application Ser. No. 10/177,577 discloses a system and method for detecting monitoring and evaluating hazardous situations in a structure. Sensors having two-way communication capability are strategically located in a structure or in a matrix of structures. These units are high-level multi-functional detectors that communicate with a base computer. However, as with the other systems discussed above, there is no spatial relationship provided for users so that they can determine their exact relationship to the hazardous situations within a structure.
- Spatial relationship is further indeterminable in the prior art due to the type of displays, viewers, or graphic view ports, used to view the graphically represented floor plans or drawings.
- Two traditional types of displays used in the prior art are either 2D displays or 3D displays. Though each display provides users individual benefits, these benefits are limited. For instance, a 2D display can be used by a user to plot a space with respect to the entire building or structure, however the 2D display cannot describe the complete geometry nor visual qualities of the interior of a room or passageway of a structure.
- the prior art provides for visualization of graphics either in 2D or in 3D in isolation, however a display is needed that provides improved viewing capabilities to take advantage of a novel visual data relationship created by the invention.
- a display would provide the cumulative advantage of both the 3D and 2D displays.
- a display is needed that would create a synchronized true scale visual relationship between two related and connected but independent data perspectives in a way unseen in previous technologies.
- a display is needed that can form a symbiotic data visualization between true scale 3D and 2D displays, which is not realized when such displays are viewed independently, even when viewed in succession.
- Such a display would permit simultaneous display of a route in 3D and 2D with concurrent access to critical, measurable, spatial and relationship data via a true scale coordinate-linked display. It is also desired that such a display would produce an accurate, true scale measurement of the route.
- the present invention provides a true scale, coordinate matched, linked in real time, dual three-dimensional / two-dimensional visual display (viewer).
- the combined, simultaneous and real-time visual display of the present invention can be used to effectively assess risks, define safe and kill zones, visualize critical assets, alarms and sensor, hazards and true scale
- 3D and 2D displays in a synchronized, coordinate-linked, true scale visual display, contextual location and spatial data are no longer mutually exclusive. Rather the combined 3D/2D display uses scale information embedded in the header of an image to enable a user to attain real time information that can be manipulated simultaneously in 3D and 2D provides a unique state of situational awareness and intelligence of the environment being viewed.
- the simultaneous display of the 3D and 2D views are independent of 3D and 2D window placement or size, fixed or floating.
- the present invention also provides a measurement tool for use with an application suited for viewing a digitized drawing.
- the measurement tool computes lengths and areas (both regular shaped and irregular shaped areas) from a digital drawing in true scale. This is particularly advantageous with digitized architectural drawings or other drawings that are scanned from paper into a digital format where measuring or annotating the drawing in true scale is important and not easily maintained over time or recaptured if it is lost.
- the present invention comprises the steps of digitizing a paper document, capturing the scale data and the physical parameters of the paper being digitized (e.g., scanned), embedding the scale and physical parameter data in a header associated with the file of the digitized image, and then storing the digitized image.
- the present invention further provides for the processing of the header data when viewing the digitized image through a viewer application such that the header data can be used in calculating the true scale line lengths and areas. For example, when the digitized paper being viewed is a floor plan, then the header data can be used to measure distances and areas on the floor plan in true scale. Once the line is drawn, the true scale measurement is calculated using the header scale data, then it can be further converted to a desired unit of measurement and then presented to the user.
- the step of capturing the scale and physical parameters of the paper being digitized comprises capturing the original scale information of the paper, the DPI of the scan, and the original size of the paper. If the paper is imaged as a TIFF file, then the captured data is stored in a private tag of the TIFF header using TIFF header tags. It is known by those of skill in the art that the TIFF header has both private and public TIFF header tags and that public tags are intended for a particular or singular data type while private tags must be registered to retain data for a particular purpose. For instance, public TIFF header tags for file size cannot be used to store other data such as description data or scale data. Private tags are open fields and do not have data that is intended to go in them unless they are registered tags. Private tags can be used by software developers or be registered to private companies so that particular tag can be used for one designated, well-defined purpose.
- a user can use the drawing tools that are a part of the viewer to draw a line or shape.
- the locations of the pixels that define the line or shape are captured by the viewer for use with the header data to calculate the true scale measured length of the line.
- the present invention provides for the measurement of lengths (for both lines and polylines) and areas (for both regular shapes as well as irregular shapes, such as rectangles, polygons and inverse polygons).
- a Find Shortest Path tool that in part uses the embedded scale information in the TIFF header to calculate the shortest, fastest path between two user chosen or dynamically updated points marked on the 2D map or in the 3D rendering
- the Find Shortest Path tool can also calculate and simultaneously display multiple routes between two user chosen or dynamically updated points e.g. the Primary (shortest) route, the Secondary (next shortest) route, and Tertiary (optional) route to allow for advanced contingency planning
- a barrier tool that allows discreet pathways and entry / exit points to be manually or automatically marked as impassable, stairwells to be marked for attack or evacuation, and have those dynamic details trigger a recalculation of the shortest path.
- the 3D Record Path tool records a path navigated on a 3D window and
- a Door Detection Tool automatically tabulates environmentally orientated doorways and passageways along an allotted path as a critical aid to emergency and response personnel operating in adverse conditions such as dark and smoked filled environments. Generated path can be stored and embedded in the digital file to facilitate planning, preparedness, simulated evacuations, and enhanced training.
- the scale plans are useful to emergency personnel for planning ingress and egress routes for buildings or structures, including stadiums, arenas, bridges, tunnels, wharfs and the like. Additionally, point-to-point routing, manual or programmatic is easily determined.
- the scale plans are useful to the public and emergency personnel for planning ingress and egress routes both before and during an emergency.
- building tenants or management can use the disclosed system to determine pre-arranged routes for entering and exiting the building while viewing such detail simultaneously in 3D and 2D.
- emergency personnel can use the invention's dynamic searching and delivery capabilities to determine, in real time the routes to emergency exits.
- the system also allows emergency personnel to determine multiple routes presented in a hierarchical shortest to longest format to and from a specific building location or area, and allows them to access or block specific portions of the building in both 3D and 2D.
- the system allows the routes to be determined across multiple stories of a building, taking into consideration all human
- transportation infrastructures e.g. building stairwells, and even from the exterior of a structure to any accessible location on any floor of a structure.
- the current invention facilitates point-to-point routing within a structure, allowing personnel to identify exact measured routes for reaching a specific location.
- Emergency personnel will know how to get from point A to point B, and the exact distance they must travel along the route.
- firefighters will know exactly how far to go in any given direction to reach a location.
- security can utilize the disclosed system to pinpoint problem areas and address security situations that may arise. Both emergency personnel and tenants or other people in the building will be able to determine the location of emergency exits and routes to the exits.
- Various routes to emergency exits can be determined in real time using dynamic searching.
- the invention can deliver the scale plan information in at least three ways.
- the invention displays the information on a computer monitor screen or display device and allows users to pick selected points or areas using a pointing device, such as a mouse, stylus or other user directed selection device.
- the invention can display the information on hand-held devices that personnel can carry.
- the system can use a heads-up display, which displays the relevant information in a user's line of sight. Using the invention in this manner would aid firefighters who often work in situations involving reduced visibility. With the invention, a firefighter walking in darkness can view a heads-up display that details any needed information, including current location and routes to a desired destination.
- to-scale displays can be used so that a planning board or planning personnel can determine access routes as well as containment strategies or other strategies.
- pre-arranged routes can be developed by building tenants or building management to determine ingress and egress routes which can increase fire safety preparedness, effectively for fire drills and training.

If desired, further measurement conversions can be performed to calculate any unit of measurement desired. For example, measurement units can be converted from inches to feet or meters by simple multiplication of the unit conversion factor.
- the area of a polygon 88 is next illustrated with reference to FIG. 11.
- the user initially triggers these calculations with a mouse-down event (while the polygon annotation is selected from the drawing tool bar). This event gives us the first point of reference (X 1 ; Y in pixels.

- This provides, for use in the calculation of the length, with (n+1) nodes and (n) line segments; 'n' is arbitrary and absolute. With this collection of points one can iterate through the line segments and get a running total for the area.
- This area is calculated by first identifying a baseline below the polygon, then identifying a trapezoid whose sides consist of (1) a single line segment on the polygon, (2) a line from the rightmost point in the polygon segment to the baseline which is perpendicular to the baseline, (3) a segment of the baseline, and (4) a line from the baseline to the leftmost point in the line segment (drawn perpendicular to the baseline).
- the area of the trapezoid is calculated with Equation (13) below: n
- This area (in inches) is then squared and multiplied by the square -root of the blueprint scale (embedded into the header of the TIFF image) to produce the actual area (in inches) of the selected rectangle, as provided by Equation (15) below:

- the scanned document may include floor plans from a single building, or more likely a collection of buildings.
- a true scaled three dimensional virtual digital model rendering (also called the 3D digital image or 3D digital rendering) is created based on the two dimensional digital raster image. Specifically, the viewer and the associated tool sets are used manually, or through programmatic steps, to annotate the 2D digital raster image so that the properties and positions of the 2D annotations are programmatically translated to create a scene graph which is then used to create the associated-3D digital image. See block 205.
- the scene graph lists the objects, properties, and transforms that describe the 3D digital image.
- the scene graph is organized by loose groups of similar object types rather than any specific order of objects.
- each file may be organized and stored as individual yet associated files using a file system in the database sever 14, the memory of any computing device or a central data repository. See block 210.
- Individual documents are stored in a file server and associated to database records. Documents may preferably be organized in the database by building and floor or some universal standard.
- the user may search the database for the digital image file to be viewed at a workstation 16 using a computer or laptop 28a or the like. See block 220. Users of the database can locate and view individual digital plans or groups of digital plans.
- the database can be located on a closed network, a web accessible network or a localized computing device with no network connectivity.
- the user can query the database to locate a specific digital image or group of digital images (block 230) such as an entire 3D building, a digitized floor plan document or the individual floor 3D scene.
- the selected digital image file is then distributed to the workstation via the network 24 and viewed, to-scale on a dual 3D/2D digital image display/viewer 240.
- the digital viewer 240 may include but is not limited to synchronized graphic rendering devices, synchronized user interactive graphic displays, linked graphic representations, real time event linked display mechanisms, synchronized horizontal display surfaces, synchronized holographic displays, synchronized graphic screens, dual monitor heads up displays, auto stereoscopic displays and immersive graphic environment.
- the digital image file is pre- populated onto mobile computer systems with 3D enabled video graphic hardware and software.
- the digital image display/viewer 240 can open and render the digital image files and retrieve the original image/document scale information that is embedded in the 2D digital image header.
- the digital image display/viewer 240 has a multiple document interface having display means, windows or view ports that are linked and coordinated and can be seen simultaneously.
- FIG. 14 An illustrative user interface of the display/viewer 240 is shown in FIG. 14 comprising an application shell 243, two document view ports (a 3D window 242 being 3D graphics enabled and a 2D window 244 being 2D graphics enabled), a basic set of drawing tools and a menu interface to activate functionality and interact with the 3D and 2D displays.
- Both the 3D window 242 and 2D window 244 can be sized and positioned to the user's preference.
- the 3D window 242 occupies 40% of the left hand side (LVP) of the display/viewer 240 and the 2D window 244 occupies 40% of the right hand side (RVP) of the screen.
- LVP left hand side
- RVP right hand side
- Images displayed on the 3D display 242 are true scaled three dimensional digital renderings that are initially viewed as a ground plain view wherein the user perspective is parallel to the plain of the document surface.
- the view angle can be manually changed and rotated on the X, Y or Z axis permitting the user a view perspective at any desired angle or height. See Fig. 14.
- Images displayed on the 2D window 244 are viewed perpendicular to the surface of the document. For instance a scaled digital floor plan or an architectural drawing view in 2D will be viewed in plan view which is maintained when the document is zoomed or rotated or otherwise manipulated.
- the 2D digital raster image is the master file, real data, and is the origination point for data as scale data is embedded and read from the digital image rendered in this location for both the 3D and 2D windows.
- the simultaneous viewer 240 serves as a tool that provides the user with an enhanced awareness of a situation or environment and an overall intelligence of the structure shown in the drawings.
- the user can manipulate the digital images using the simultaneous viewer 240 using tools employed with the viewer 240. For instance, the user can identify start and end points on an image displayed in a select window (block 250), use the shortest path tool to find the fastest route between two graphically marked/user chosen points with no restrictions or limitations on the end and start point locations in context to the building image (block 260), select an stairwell and set it to be an Evacuation stairwell which will then only allow that stairwell to be used for routes calculated from a building floor down through the structure and / or an attack stairwell which will then only allow that stairwell to be used for routes calculated from a building location up through the structure and force the Shortest Path tool to use that stairwell as a first node in the route calculation (block 265), calculate the shortest path between points and display the total distance using the shortest path algorithm and the embedded scale information (block
- the scanned document creates a true-scale 2D digital image, which is displayed in the 2D window 244.
- the captured scale data is embedded in the TIFF header of the 2D digital image.
- Each object represented in the 2D digital image of the 2D window 244 is represented by a 2D primitive, usually a line for a wall, or a rectangle for a door, window, or other object.
- the shapes represented by the digital image in the 2D window 244 may be either 2D only data (being data that does not have 3D-associated representations) or data with 3D-associated representations, also called 3D related objects.
- the 3D-related objects have additional information relating to type, orientation, off-ground position and object height that is not realistically presentable in the 2D window.
- the scale information embedded in the original raster 2D floor plan is also used to construct a true scaled three dimensional digital model image , specifically the scale information is translated into associated 3D virtual models via the scene graph.
- the 3D digital image/3D digital rendering displayed in the 3D window 242 is prepared using the 3D-related objects data graphically overlaid on the original 2D digital image displayed in 2D window 244.
- Each object in the 2D data set is evaluated to extract information contained in 3D related objects and any predefined model associated with the object is added tp the scene graph.
- (2D Data annotation objects representing walls do not have separate associated models.
- the 2D wall annotations are directly extruded into true scale 3D geometry elements.
- the 3D objects are arranged using positional coordinate information, 3D object data structures are created, and pointers to the 3D structures are added to the associated 2D object data sets.
- a user can use a computer mouse to manually navigate the 3D virtual model of the building and virtually walk through rooms and hallways of the model displayed on the 3D window 242.
- a 3D window camera is used with the 3D window 242 to assist in viewing the path taken in the 3D virtual model.
- the 3D window camera can be set in a location to define the view of the structure that is presented in the 3D window 242 and render the scene from the camera's point of view.
- the path taken in the 3D virtual model can be viewed as if the virtual moving camera is positioned on a person's head.
- the display/viewer 240, the 3D window 242 and 2D window 224 are designed to work in cooperative form.
- the 3D window 242 and the 2D window 224 may be child applications of the application shell (a parent application) 243, or two separate applications may be tied to a third application, or all three applications are tied together.
- the display/viewer 240 the user can not only simultaneously view the 2D digital image of a floor plan in the 2D window 244 and the associated 3D digital model image of the structures and objects of the floor plan 242 but also synchronize, in real-time an action taken in one window and display it in the other window.
- the user can manipulate or derive information from the digital images.
- the present invention allows the user to open one window, 242 (see Fig. 15) or 244 (see Fig. 16), and manipulate the digital image using only the open window alone. All changes or other input made in the open window is tracked and relayed to the closed window when it is opened again, for instance, by the parent application 243 (see Fig. 17) when the parent application is used to manage all changes made in the 3D window 242 and 2D window 244.
- the 3D window 242 and 2D window 244 of the display/viewer 240 are true to scale, coordinate matched, and linked in real time providing an interaction between the images in each the 3D and 2D windows 242, 244.
- the mechanism by which the objects are kept accurately synchronized is accomplished by associating scale, selection events and coordinates from one window 242, 244 to the other window 244, 242, respectively.
- the scale information of the original image/document is embedded in the digital image header. This data is retrieved and used by the digital image viewer 240. As the 3D digital image is associated to and based on the 2D digital image, the true scale value is the same in the two windows 242, 244. In some embodiments the scale between the windows 242, 244 could be different. In such cases an algorithm may be used to translate the scale from one window to the other.
- Selection event synchronization takes advantage of the fact that each object movement or position change (user input) creates a software selection/transform event. These selection events provide the identity and updated position for the object. Depending on which window the user employs, the selection events or action taken by the user in one window is simultaneously repeated (causes a re-draw) in the other window. Generally, when an object is moved, the selected object is flagged, a 2D selection event list is cataloging each
- Processing Program will cycle through the 2D selection event list checking the flagged objects and deleting the corresponding 3D representation of the flagged 2D object in the scene graph.
- the 3D data is deleted during an update of the 3D digital model image as it is translated from the real 2D data.
- the 2D selection event list containing the updated information is then iterated through and new 3D objects are generated and placed into the scene graph. Accordingly, to effect a change to an object's 3D representation, it must be located in the scene graph, its data updated, and the scene graph re-rendered. The replacement of the objects straightforward and efficient given that the scene graph is organized as loose groups of similar object types.
- the scene graph can be manipulated so that updates do not cause the entire scene to re-render only the affected objects for which a selection event is recorded.
- a selection event is triggered, a flag is placed by the 3D selected object in the scene graph and a 3D selection event list is created.
- the selection event occurring in the 3D window 242 possesses the identity of the object and transform information for the action taken.
- the transform is the new X, Y and Z positional and rotational angle information that has been applied to the 3D object.
- the transforms are applied to only the selected 2D object(s) in the 3D selection event list.
- the selected 2D object data is not deleted but rather is directly modified because 2D data is treated as the real or source data.
- the selected 2D data is updated using known scaling factors and position and orientation information needed to correctly show on the 2D digital image or representation in the 2D window 244. Additional information such as z-axis rotation or vertical position information cannot be shown in the 2D window, but is saved in the object's data set.
- the coordinate matched feature of the dual three-dimensional / two-dimensional visual display/viewer 240 is based on a non-rendered mathematically accurate grid system.
- Each of the 3D and 2D digital images has a non-rendered grid positioned on top thereon reflecting the precise pixel dimensions of the document.
- the coordinate system of each window in the display/viewer 240 is linked to a common referenced point or cross referenced point usually being the upper-left corner of the floor plan as the 0, 0 point.
- a 2000 W x 1500 H pixel document has a corresponding 2000 x 1500 space grid on top of it. This grid is a computed virtual entity that is not drawn or seen and can extend infinitely on any axis.
- the upper left hand corner of the document is the 0 Y (Vertical Axis), 0 X (Horizontal Axis) and, when applicable, 0 Z (Three -Dimensional axis).
- the coordinate system inherent in the display/viewer 240 enables linking by allowing a discreet set of pixels to be colored graphically to mark a chosen shape, line or point. Indeed a point marker could be as small as 1 pixel W 1 pixel H. Because pixels have a definitive size that cannot be divided graphic representations of lines and shapes are always estimations.
- the coordinate system allows relative positions to be defined and corresponded to other relative or arbitrary positions.
- the coordinate system of the present invention may even correspond to real world locations defined by coordinates of outside systems such as geographic coordinate system including latitude and longitude, e.g. a GIS systems.
- the display/viewer 240 can receive coordinate input from a third or outside coordinate system as long as the external coordinate grid and scales can be converted to the coordinate system shared by the windows 242, 244. Such conversion occurs by translating the disparate coordinate system scales and defining at least one common reference point. Preferably multiple common reference points would be established.
- the present invention allows users to receive coordinate data describing the location of an asset or object based on the Geographic Coordinate system and translate those coordinates to an exact spot on the 3D and 2D windows 242, 244 representations of a structure.
- a point defined graphically in the 2D window 244 can be calculated to have a certain coordinate position because of the grid and a relative true scale measured size resulting from scale data that is embedded in the digital image header.
- the present invention combines contextual and structurally connected visual information to allow the user to obtain an enhanced situational awareness of a structure and to intelligently navigate through the structure. For instance, users can simultaneously see their immediate true scale spatial environment in the 3D window 242, (along with what the room looks like) and their accurate, true scale orientation (with respect to the end point/goal) and current position in the building as shown in the 2D image displayed on the 2D window 244.
- display/viewer 240 when combined with the tools of the viewer 240 allow the user to interact with the digital images in each window 242, 244 and thus better understand an environment.
- the user can manually trace out a route, experience (virtually walkthrough) the route, describe the route's environment during the virtual walkthrough, see a real time position indicator for the assets location in the 2D view port, and obtain the true scale measurement between objects and locations or of the navigated path displayed and saved. Also, once the 3D visual navigation of the structure can be recorded, it can be made distributable using standard video files outputs.
- the tools employed with the display/viewer 240 include but are not limited to a basic scale measurement calculator 22, a basic graphic drawing tool set capable of making precise colored annotations on the digital image, a Find Shortest Path Tool 300, a Path Barrier Tool 360, a Door Detection Tool 330 and an Evacuation Simulation Tool . These tools may be managed by the parent application 243 and can be used in either window 242, 244. [00153] Drawing Tools
- the drawing tools 410 permit a user to construct lines, shapes and points with vector or raster graphic drawings. These drawings are then presented on a layer on top of the original drawing, digital document.
- the user can trace out a path on the 2D window 244 using the basic drawing tools and have the same path rendered precisely and programmatically in the 3D window 242.
- the path shown in the 3D window is contextually correct being true to scale and reflecting the accurate measurements of a structure.
- a route virtually walked in the 3D window 242 can be visually recorded as a user generated animation, saved and played back, as discussed below.
- the Find Shortest Path Tool 300 uses an algorithm to automatically calculate and allow the visual plotting of the shortest path between points selected in either the 3D or 2D windows.
- This Find Shortest Path Tool works by transforming the map matrix and distance/area data present in the digital document floor plan image and automatically calculates the shortest path.
- the shortest calculated path and the associated path true scale measurements are known and able to be calculated as a result of the scale that is embedded into the header of the TIFF image.
- a user selects the Find Shortest Path tool 300 then graphically marks start and end points on one digital image in a selected window. For example, an emergency personnel can mark the start point 302 as being a doorway in a building and mark the end point 304 as being a computer classroom in which a victim or hostage is said to be located and using the Find Shortest Path tool 300 calculate the shortest path 306 between the two points. See Figs. 18A and 18B.
- the tool 300 can be used on a single floor, as shown in Figs. 18A and 18B, or across multiple floors, see Find Shortest Path tool 301 as shown in Fig. 18C.
- This tool 300, 301 can assist emergency response or other personnel in navigating from the doorway to the stairwell even when the floor of a building is visually or physically obstructed.
- This Find Shortest Path tool may also be used by emergency response personnel to determine the fastest route to an emergency location inside a building even before arriving on scene or when having no prior knowledge of the building's interior structure, saving precious time.
- the shortest path is represented in the 2D window 244 by a colored line 306 that follows the exact calculated path through the structural drawing and in the 3D window 242 by a red 3D floating poly line shape 308. See Fig. 18B. A visual display of the true scale measured path is also shown.
- the user can position the 3D window camera to the preferred structural entry point and easily visualize, and identify the beginning of the shortest path.
- the shortest path marker and path directions can be communicated to the fire rescue team or obtained by the team themselves on site. Additionally the calculated route can be automatically played back as a walkthrough animation allowing emergency personnel to see the entire route and all the building structural elements, objects of interest and hazards along the way.
- Fig. 19 shows the Path Barrier Tool 360,which is used to graphically mark pathway obstructions and hazards that will prevent passage through a particular area or as a general hazard marker.
- the user selects the Barrier tool then graphically marks the affected area in either window to trigger the programmatic placement of a scaled visual "Do Not Enter” marker into the window data sets. This action accurately changes the visual geometry of the 3D and 2D scenes, 364, 362 respectively, and mathematically alters the makeup of the map matrix used by the Find Path Tool.
- the invention can automatically or manually recalculate and visually render the shortest path options taking full consideration of the reduced route options.
- This tool 360 can be used by emergency response personnel to instantly and accurately update tactical response plans and instructions using real time events and user interaction with the invention to transform map and measurement data into site specific real time contextual intelligence.
- the Door Detection Tool 330 may be employed with the 3D window 242 and is used to automatically and programmatically count the doors in a selected path or virtually passed by the invention user. See Fig. 20.
- a running count may be visually displayed to the user of this tool in the 3D window.
- a dialogue box may appear to show each the left door count 332 and right door count 334.
- the total door count can be communicated to the fire rescue team or obtained by the team themselves on site. Fire rescue teams can use the Door Detection Tool to count the number doors or determine locations of doors in a selected path and even verify that they are on the right path.
- the Door Detection Tool is therefore also useful in mitigating navigation through low visibility environments.
- the display/viewer 240 may also employ a 3D Record Path Tool 350. See Fig.
- This tool 350 is best used with the 3D window 242, however with some modifications this tool could also be used in the 2D window 244.
- the 3D Record Path Tool 350 allows application users to visually record every virtual movement and scene being viewed in the 3D window 242.
- the 3D Record Path tool When the 3D Record Path tool is turned on, the 3D camera's true scale start point 352, the exact path taken 354 and current position 356 in the 3D digital image are simultaneously and in real-time graphically displayed on the 2D digital image floor plan shown in the 2D window 244.
- the 3D window 242 will show the 3D view of the path 354 shown in the 2D window.
- Reference number 358 shows the 3D view taken at the current position 356 of the path 354 shown in the 2D window 244. So as the user virtually walks through the 3D floor plan model, the user's virtual position is directly associated to an exact coordinate on the original 2D floor plan. Also, the exact, true scale measurement of the path's length can be shown in the measurement box 400.
- the visual marker used in the 2D window 244 may be a red line that is drawn in a visual layer on top of the 2D image.
- the red line will essentially trace the path the user is walking in the 3D view and plot marker points or route nodes along the way.
- a measurement dialog may be employed with the present invention to display the accurate measured length of the recorded path in real time using the embedded scale data.
- the user not only sees the exact path taken along with starting and ending points, but can replay the virtual 3D path that was walked in the 3D window 242 or save the entire 3D visual sequence, i.e. animated movie, out to a standard .avi, mp4 or a variety of other standard video formats for distribution.
- the 3D Record Path functionality can be used in a variety of situations and contexts. For example, a user can create an accurate, to-scale virtual model of a museum floor plan by scanning paper drawings of a section of a museum. When the 3D digital image is created, any furniture, sculpture, and wall hanging art objects can be accurately modeled and represented inside the 3D museum floor plan. The application user could then walk through the virtual 3D museum and initiate the 3D Record Path tool to view an accurate visual representation (or movie) of the path taken. This may be useful to guide museum patrons through a museum exhibit, or allow a remote museum curator to view exact accurate museum and art layouts in another country without physically being present at the viewed museum. This tool could also be used to market materials and virtual art shows as well as to curate entire shows from remote locations without the expense of onsite visits.
- the 3D Record Path Tool could be employed by emergency crews to gain invaluable insight into the interior layouts of buildings during emergency situations.
- tactical information gathered on scene can be used in conjunction with the 3D floor plan models and allow users to gain a detailed, fully to-scale visual guide of emergency locations.
- the user can plot entry or exit routes in a structure, automatically view the entire length of the path in a true scale 3D animation and intelligently adjust the navigation path based on architectural and hazard elements that can only be visualized and incorporated into the digital images using the present invention.
- 3D floor plan visualizations can be used to make further tactical decisions based on the information being rendered and the novel manner of presentation at command and control or sent out into the field as pre-planning guides for emergency responders on scene. All these uses maintain accurate scale and measurement data throughout because of the embedded scale in the TIFF header. It should also be noted that the raster image created using the tools of the present invention is transmitted from one source to another maintaining true scale throughout the entire process and end user activity.
- the Evacuation Simulation Tool allows users of the 3D / 2D synchronized viewer 240 to extend the data calculated by the shortest path tool 300 to larger scale simulations. In essence, once a shortest path has been calculated by the Shortest Path Tool 300 and the path has been graphically displayed in the 3D and 2D viewports, the end user can select the path in the 3D or 2D window and activate a new function through the right click menu.
- This Evacuation Simulation tool would work with Population Density data encoded in the building 3D / 2D data set to describe the number of persons that are in the vicinity of the Shortest Path Start Point.
- the Evacuation Simulation tool would then use the true scale dimension information embedded in the tiff header to calculate the dimension of the surrounding area and the area taken by the estimated population.
- the Evacuation Simulation tool would then calculate how long it will take to move the total estimated number of people encoded in the Population Density data along the true scale calculated shortest path, through all the structural bottlenecks to the end path location.
- Each of the tools described above can be used alone or in any combination.
- the user can combine the Find Shortest Path Tool 300, 301 and the 3D Record Path Tool 360 to not only follow the shortest path in one window that is simultaneously being plotted in the corresponding window, but also view a recorded movie of the selected path taken from the 3D digital rendering.
- the user may also manually record on either digital image the presence of additional hazards, obstructions or other data noticed on-scene or while watching the replay of the recorded 3D virtual path from the 3D Record Path Tool.
- This added information can be then distributed/relayed to the other emergency responders inside or within the real world building location or else where permitting quick entry and exit of the building.
- This feature allows emergency team leaders and command and control personnel to continually update their response plans as new information is obtained by using the invention. Information that, would in part, not be available to the end user without the invention.
- the true scale, coordinate-matched, linked in-real time, dual three-dimensional / two-dimensional visual display/viewer 240 can be used to track real world objects (assets) and simultaneously mark, graphically, their location on a 2D floor plan and as a corresponding object in the 3D window 242.
- This combination of contextually related visual environments enables the transformation of two independent streams of data into one coherent piece of information.
- an emergency responder can be outfitted with a transmitter / receiver device.
- These devices use a location method to identify where an asset is in relation to some scaled, coordinate based system.
- asset coordinates can be obtained in relation to the GPS Geographic Coordinate system or a localized location grid that creates a grid entity and ties asset location to a coordinate within that localized grid.
- a responder can be outfitted with a GPS device capable of receiving/transmitting location or identification signals to either a receiver location outside of a building or a receiver already existing within the structure which may be outfitted with a disaster proof signal repeating and amplifying unit.
- These repeating signals and amplifying units are designed to pick up the lower strength / lower powered personal GPS device signals and retransmit the signals to external receivers so that location data can be calculated.
- the responder can also be outfitted with a radio transmitter and receiver, this can be referred to as the asset tag.
- a localized set of computer connected mobile transceivers send out radio signals and receive signals back from the asset tags.
- the present invention may employ a triangulation or a multilateration method, known in the art, in detecting coordinates for an asset or emergency responder.
- the asset tags location can be determined in reference to this localized grid in a variety of ways depending on the type, strength and broadcast reach of the asset tag and receiver stations.
- the asset coordinate data of the emergency responder can be graphically rendered simultaneously using the 3D / 2D dual visual display/viewer 240 of the present invention. As the asset location coordinate data is updated, the location of the object or emergency responder is also updated in the 3D and 2D digital images.
- the display/viewer 240 and the tools of the present invention provide the user with an understanding of the contextual 3D / 2D visual environment by allowing the user to see an object's (or asset's) location rendered in a manner not realized by the prior art.
- the present invention is also useful as an analysis tool. For instance, if an asset is navigating a structure in a compromised, hazardous, or visually impaired situation the immediate dangers, percentage of route completion and alternative routes in reaction to changing conditions on scene can be evaluated and reacted to with information transformed by the present invention.
- a fire is reported burning on the third floor of a four-story structure.
- the emergency responders uses a laptop 28a to access the floor plan data of the burning building either on-site or on route to the building. Once the floor is located, the emergency responder can open the desired digital images using the display/viewer 240 and manipulate the data in several different ways all of which can occur simultaneously.
- the user can identify all entry and exit points for the structure using the 2D window 244 in the digital image display/viewer 240 and the select the Find Shortest Path Tool to determine the shortest and fastest path from one point on the floor to an exit point.
- the user can place the 3D window camera to the preferred structural entry point or their current position in the building and view the calculated path.
- the 3D Record Path tool may be employed at this time to record the path taken in the 3D digital image (3D virtual model) of the building. This video can be replayed back or distributed by wire or wirelessly to other emergency personnel.
- the Door Detection Tool may be used to count the number of doorways or entryways until the desired end point is reached. This data is essential to visually impaired environments where tactile verification is needed for navigation. This data can be found on almost any typical architectural floor plan but it must be manually tabulated along a desired route for the data to be meaningful or offer any usable intelligence. The use of the current invention overcomes this serious deficiency in the art.
- the building is internally equipped with a receiver / amplifier and the emergency responder involved in an interior attack or as part of a rescue company in a fire hot zone is equipped with a GPS device or radio transmitter, outside personnel may be able to visually track the responder' s exact coordinate within the third floor of the building and verbally instruct the responder to any new occurrences or changes to the emergency situation or with additional information based on the systems visual display to assist the responder in dealing with conditions that they are discovering and reporting back to outside personnel in the interior of the building.
