Definitions

  • a sight or optical viewer which incorporate lenses to magnify an image or simply passes through light without magnification also referred to as a“scope,” is a sighting device that is based on an optical refracting telescope or other optical viewing device. It includes some form of graphic image pattern (a reticle or cross-hairs) mounted in an optically appropriate position in its optical system to give an accurate aiming point.
  • Telescopic sights are used with all types of systems that require accurate aiming but are most commonly found on firearms, particularly rifles.
  • a telescopic sight may include an integrated rangefinder (typically, a laser rangefinder) that measures distance from the observer’s sighting device to a target.
  • a compass is an instrument used for navigation and orientation that shows direction relative to the geographic“cardinal directions,”, or“points.”.
  • A“compass rose” diagram shows the directions north, south, east, and west as abbreviated initials marked on the compass.
  • the rose can be aligned with the corresponding geographic directions, so, for example, the "N" mark on the rose really points to the north.
  • angle markings in degrees may be shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.
  • GPS data typically provides a three-dimensional location (latitude, longitude, and altitude (elevation)). For example, a sample GPS of a location in Philadelphia is as follows:
  • Miniaturized GPS devices are known that include a GPS receiver for providing GPS location data and an orientation sensor for providing attitude data.
  • the orientation sensor may derive its data from an accelerometer and a geomagnetic field sensor, or another combination of sensors.
  • One such miniaturized GPS device that is suitable for use in the present invention is a device that is commercially available from Inertial Sense, LLC located in Salem, Utah. This device is marketed as“pINS” and“pINS-2” (“INS” is an industry abbreviation for“Inertial Navigation System.”)

Accordingly, through various standards, it is possible to implement point to point, point to multipoint and mesh WLAN, all of which are suitable for use with the present invention.
  • Mesh network topology has significant advantages for mobile devices, particularly in remote areas where there is limited cellular service since each node can be connected to multiple other nodes and there is no required path from any node in the network to any other node.
  • a further advantage of a mesh network is that as long as any one node in the mesh network has access to the Internet such as by way of a cellular or satellite connection, all of the nodes in the mesh network have access.

  • the lead scope and follower scope(s) When calculating a presumed target position from GPS data and the other measurement devices, there are known, quantifiable errors introduced by the lead scope and follower scope(s), which can be represented by discrete values (e.g., +/- 20 cm). Certain types of errors will be consistent from scope to scope based on inherent limitations of the measurement devices. Other types of errors may depend upon signal strength, such as the strength of a GPS signal or number of satellites used to calculate the position of the lead scope. For each calculated target position, the lead scope, follower scope and/or network server identifies the error value. When amalgamating and accumulating target positions from multiple scopes to calculate an updated target position, the error values may be used to weight the strength given to each target position.
  • target positions with the lowest error values may be more highly weighted.
  • a target position with a very high error values compared to other target position error values may be deleted from the calculation.
  • One way to use the additional data to more accurately predict the position of the target would be to place points representing each estimated target position on a 3 -dimensional grid and estimate the center point or average location of the data representing the estimated targets. The center point can be adjusted based on weighting as discussed above.
  • a temporal factor may be used. For example, the most recently observed target positions may be given greater weighting. Certain target positions may be eliminated entirely from the weighting after a predetermined period of time has passed from the observation time.
  • the temporal factor may also be affected by the nature of the target for embodiments where the type of target is determined (e.g., car, person, deer) by the IAMS and/or by the scope.
  • the temporal factor is likely to be more important for fast-moving targets compared to slow- moving targets.
  • a fast moving target e.g., a car
  • the most recently observed target positions may be given significantly greater weighting, and older target positions would likely be eliminated more quickly from the weighting compared to slower moving targets.
  • the IAMS may also use various algorithms to determine if the target is actually moving, and if so, at what speed. This calculation may then be used for the temporal factor. For example, if a target appears to be stationary, then no temporal factor will be applied to the weightings. The algorithm may look at multiple observed target positions and if they are relatively similar after factoring in their respective error values, and were observed at significantly different time intervals (i.e., not very close in time), it can be concluded that the target is stationary.
  • the visual indicator visually communicates the error information in a form that is useful to the device operator.
  • an error box may by overlaid around the dot so that the operator of the device knows that the target may be in any of the areas within the error box, and is not necessarily exactly where the dot is showing.
  • the error box presumably becomes smaller as more target positions are identified by a succession of follower scopes.
  • the exact manner in which the error information is communicated depends upon how the presumed target position is displayed on a follower device.
  • the target is represented by a one-dimensional object on a display screen, such as a dot.
  • the target is represented by a simulated two- dimensional or three-dimensional image on the display screen. If a digital image is captured and transmitted, the actual image of the target may be displayed on the screen.
  • IAMS image analysis and manipulation software
  • AI artificial intelligence
  • the simulation process allows for the target to be rotated so that it appears properly positioned with respect to the follower scope.
  • a lead scope identifies a deer (target) that is a quarter-mile away and is facing the device head-on.
  • the target position of the deer and a physical image of the deer is captured by the scope and communicated to the network server.
  • the IAMS in the network server or remotely accessed via the Internet identifies key visual features within the image and compares these features with known objects to categorize the target as a front view of the deer and retrieves a simulated image of a deer from its database.
  • a follower scope receives target position data regarding the deer, and it is determined that the follower scope is also about a quarter-mile from the deer but is 90 degrees off compared to the lead scope.
  • the IAMS can then rotate the simulated deer by 90 degrees and communicate a side view of the deer for display on the follower scope so that the follower scope knows what the deer is likely to look like.
  • the IAMS could attempt to match the target image to a person using facial recognition or other biometric techniques. If there is a match, information about the target could be returned to the scopes.
  • a further application of an image display system incorporated into the scopes would be the ability of the follower scope to retrieve a high-resolution aerial image or topographical map and display the aerial image or map on the display of the follower scope together with some indicia of the approximate location of the target. If error information is known, a box can be displayed on the aerial image or topographical map showing the area in which the target may be located.
  • one embodiment includes a transparent display overlay that is activated to highlight a target in a particular color or draw a box around the target. If the follower scope has a visual display, the matched target is designated as described above.
  • a lead scope identifies a deer (target) that is a quarter-mile away and is facing the device head-on.
  • the target position of the deer and a physical image of the deer is captured by the scope and communicated to the network server.
  • the IAMS in the network server or remotely accessed via the Internet uses computer vision techniques to segment the image, separating the target from the background image.
  • the IAMS generates a set of key identifiable features within the image segment, such as the points on the deer’s antlers and a white patch on its side.
  • the IAMS performs pattern matching on the incoming follower scope images, comparing key features within the image with the target feature-set generated from the target scope and adjusted for the follower scope’s viewing angle. If a pattern match occurs, the location of the target, within the follower scope field-of-view, is transmitted to the follower scope.
  • the follower scope knows its GPS coordinates and it has received the approximate GPS coordinates of the target from the lead scope or network server (or calculated the target position based on directly or indirectly wirelessly receiving the raw measurement data from the lead scope. With this information, the follower scope (or the network server or another node in the network) calculates a route between the two GPS coordinates. Unlike a vehicle route where you are effectively only determining a two-dimensional direction from point A to Point B, the follower scope also determines a precise vector and range from its position to the position of the target. Since the follower scope also has a GPS/INS device, it uses the information concerning the calculated vector to the target to direct the user to point the follower scope in alignment with the vector to the target.
  • the preferred embodiment transmits the image and/or heat signature to the other devices in the system
  • at least a portion of the devices may not have visual displays.
  • the follower scope may rely simply on directional arrows or other indicia to direct the user of the follower scope to the target.
  • a connection between the follower scope and a pair of headphones may be used which directs the use to move the device (e.g., up, down, left, right).
  • range information from the rangefinder is not used for identifying the target at the follower scope. Since optical scopes and binoculars focus for variable distances, the guidance to target information may also include indicia to allow the user to know the correct distance to look at or focus on. In the audio embodiment, commands may be provided to focus nearer or further, look closer, or the like. Stated another way, the user is already looking along a vector calculated based on the known target location and the known location of the follower scope. The rangefinder can be used to get an idea of whether you are too far or too close to the target. For example, the target may be one mile away, but the user is currently looking 1.5 miles away.
  • the lead scope may incorporate cross-hairs or other target selection indicia such as a reticle to mark the target.
  • the rangefinder detects the distance to the target and the system determines the coordinates of the target and notifies the follower scopes of the target position as described above or communicates with an available network server to store the coordinates of the target.
  • the lead scope may incorporate the switch to send the information to follower scopes into a sensor on or adjacent to the trigger.
  • a more complex follower scope may include a higher resolution display and utilize augmented reality techniques to overlay visual information received from the lead scope and indicia directing the follower scope to the target onto an optical field-of-view of the follower scope.
  • An overlay may be implemented by a heads-up display or equivalent or by switching to a complete digital display.
  • terrain features may be on the path of the vector between the follower scope and the target. For example, if the lead scope is one mile due north of the target and the follower scope is two miles due south, there could be a hill between the follower scope and the target.
  • Detailed topographic maps and navigational tools are readily available. For example, software products such as Terrain Navigator Pro, commercially available from Trimble® subsidiary MyTopoTM, Billings, Montana, provides detailed topographical maps of the entire U.S. and Canada and incorporates U.S. Geological survey maps at various scales.
  • either a computer in the lead scope or a computer in an intelligent node in the network of connected scopes can overlay the vector between the follower scope and the target onto a topographical map of the area and determine if the vector passes through a terrain feature that would make it impossible for the follower scope to see the target. If an obstruction is present, an indicia that the target is blocked from view may be presented to the user of the follower scope.
  • the follower scope could support the simultaneous tracking of multiple targets of interest. Instead of selecting a single target of interest from a list of available targets, the user of a follower scope would have the ability to toggle each available target as shown or hidden. If an available target is set to show, indicia would be added to the follower scope overlay, annotated with a label indicating which target of interest it is guiding towards.
  • the user of a scope could make a mistake and improperly indicate that it has selected a target previously designated by a lead scope when in fact the scope is actually designating a different target. This could occur for a variety of reasons with one example being the same type of animal being within the error box.
  • the IAMS would have the capability of comparing the two images and determining that the target images have a low probability of being the same target and the that scope is acting as a lead scope and sending data associated with a new target.

  • distance e.g., same, bigger, or smaller in size, depending upon distance to the target.
  • An image is captured from the field-of-view of the follower scope and automated pattern identification is performed to determine if the expected target image from the lead scope, as it was calculated to appear by the follower scope, is actually in the field-of-view of the follower scope. For example, if a deer is supposed to appear rotated +90 degrees, a deer that is facing the follower scope head on, as determined from the automated pattern recognition, would not likely be the correct target. However, if the deer is supposed to appear rotated +90 degrees, and a deer is determined to be in the field-of-view of the follower scope and is also determined to be rotated +90 degrees, as determined from the automated pattern recognition, the deer is likely to be the correct target.

Thus, there may be a minimum distance that should be kept between the scope and the target, such as 50 meters.
  • the first step in the process is to calculate how close the scope must be to the person so as to capture sufficient facial features that would allow the algorithm to obtain an accurate facial signature. This will depend on algorithm inputs since different algorithms use different facial features, and it will also depend upon scope optics such as lens quality, optical zoom, and the quality of any digital zoom. This distance may be determined experimentally before a scope is deployed in a surveillance environment. Consider an example wherein a scope containing very high quality optics can create accurate facial signatures at distances up to 150 meters. This means that the scope (and thereby the vehicle that has the scope mounted to or integrated therein) should be positioned 150 meters or less from the target.

Abstract

La présente invention concerne un réseau de dispositifs de visualisation, comprenant un ou plusieurs dispositifs de visualisation principaux et un ou plusieurs dispositifs de visualisation suiveurs, permettant aux dispositifs de visualisation respectifs de suivre la même cible présumée. Un dispositif de visualisation principal localise une cible et communique des données de position cible de la cible présumée au dispositif de visualisation suiveur. Le dispositif de visualisation suiveur utilise les données de position cible et ses propres données de position pour générer des signaux de commande électroniques destinés à être utilisés par le dispositif de visualisation suiveur pour qu'il effectue des mouvements de positionnement de façon à repositionner le dispositif de visualisation suiveur à partir de sa position cible courante pour l'amener en direction de la position cible définie par les données de position cible reçues du dispositif de visualisation principal. Au moins le second dispositif de visualisation est monté sur un véhicule, ou intégré dans un véhicule, qui utilise les données de position cible pour se déplacer vers un nouvel emplacement de façon à permettre au second dispositif de visualisation de mieux visualiser la cible.
