- the DPI responds with location information (1210) .
- the target is aware of it's own location and when the target determines that a DPI is too close (for a particular direction of approach) (1220) the target will behave as if a natural animal had been spooked. In one option, the target will pop up (1230) and then begin transmitting constantly changing location information reflecting the fact that the targets virtual location is changing in a selected direction away from the DPI (1240) . This simulates a natural animal being spooked and running away from the approaching "hunter.” When the DPI takes a shot, the DPI records the last position transmitted from the target for hit calculation purposes (1250) .
- the intelligent target can be programmed to respond at different distances depending on the angle from which a DPI is approaching.
- the essence of the intelligent target interaction with the DPI is one of location and action. Based on the location of the DPI relative to the target, a particular action can adaptively change.

- participant information will be up-loaded to an high level record keeping facility, such as an international record keeping facility to allow for regional, state, national and international standings to be updated and stored. This can be done over the interface to the international record keeping facility (1380) shown in Figure 13.
- Animal sightings can also be recorded and stored on a centralized basis for processing and forwarding to game management authorities of various jurisdictions. Such forwarding can occur at either the international, national or local levels .

- (1410), (1415) may be appropriate.
- the weight of an individual bullet or pellet might be stored together with the muzzle velocity experienced with by the particular bullet or pellet in the particular weapon type.
- the amount of elevation offset experienced by a bullet from the line of fire is a function of range.
- a set of values can be stored for a plurality of ranges together with a corresponding drop experienced by the bullet or pellets as a function of range. The distance at which the DPI is sighted in for is required to calculate the height above or below the target sights where the bullet/pellet would strike.
- a two-dimensional table mapping the impact of particular wind velocities as a function of range is also included.

- a plurality of views of the animal at different rotations would be captured and stored.
- These image views constitute a library for scoring image processing applications described more hereafter.
- the image processing problem may be simplified by using only outlines for the reference library images and then doing an outline extraction from the captured image for comparison. A number of different elevational views are captured and for each elevational view, a set of rotational views of the animals are captured. It is preferable, that the kill zone for an animal be depicted in each view to facilitate scoring.
- Figure 16 is a flow chart of an exemplary process for automatically scoring shots taken using a DPI.
- the information captured from the DPI is transferred to the scoring computer and read by an appropriate read device.
- the image of the shot is loaded together with the corresponding data
- the scoring computer determines where a bullet or pellet zone would pierce the field of view of the camera as described more in conjunction with Figure 17 (1610) .
- the shot image will be correlated with each stored view of the target or targets indicated to determine a best match as discussed more in conjunction in Figure 18 (1620) . Once the best match stored view is determined, an outline of that view is superimposed over the identified position on the image with the kill zone identified on the outline (1630) . If the bullet or pellet zone intersects the kill zone (1640-y) , the shot by the user will be scored as a kill (1645) .
- the bullet or pellet zone If it is not, if the bullet or pellet zone intersects the animal outside the kill zone, it will be scored as a wound or maim (1655) . Otherwise, it will scored as a miss (1660) .

- FIG 17 is an illustration used to explain determination of hit point of a shot.
- a straight line running from the target acquisition point to the target depicts the line of optical alignment.
- the shot is taken when the target acquisition point is directly positioned on the desired hit point on the target.
- a trajectory for a bullet or pellet zone which would emanate from the weapon is calculated and a hit point determined at a range d from the DPI .
- the hit point or point of impact at that range may or may not be offset from the point of the target aimed at. Generally, it will be offset.
- the hit point is calculated by determining the bullet elevation offset and windage displacement experienced during the amount time that a simulated bullet would take to leave the real the weapon and travel the distance d to the target. If the distance d is less than the sighting in distance, then presumably the hit point will be above the target point as shown.
- the hit point calculated for the projectile will be typically be above or below the target point.
- the distance behind the focal point of an image plane such as F 00 or F 01 , would vary depending on the amount of zoom utilized.
- F00 at focal plane F00, a lesser displacement is experienced than that which would be experienced at focal F01 were utilized at a higher zoom.
- That amount of offset can be determined as follows:
- the number of pixels offset between the hit point and the target acquisition point on the screen can be calculated.
- the precise hit point expected for a particular weapon type and a particular type of ammunition at a give range with respect to the target acquisition point can be determined.
- Figure 18A is a flow chart of an exemplary process used for determining a perspective view to be used for scoring and for estimating animal size.
- the set of images for a particular animal type shown, for example, in Figure 15, are retrieved (1800) .
- This image set constitutes image view of a known sized animal from different perspectives at a know distance. That image set is scaled for the actual distance to target when it differs from the known distance (1810) .
- the perspective views of the individual members of the image set are correlated with the image captured by the DPI (1820) to determine a best match view. Once a best match view is selected, the view is scaled to better match the shot image until a "best" match is obtained (1830) .
- Figure 18B is a flow chart of an exemplary process used for determining prospective view to be used for scoring and for providing an alternative approach to estimating animal size.
- a plurality of sets of images of an animal of different known sizes at a given range are maintained.
- One of the sets is selected (1800B) and the image set is scaled for the actual distance to the target (1810B) .
- a perspective view from a selected image set is determined by best match image correlation with a captured image (1820) and the next set is selected (1825) if at least one unprocessed set remains.
- the best match of views obtained from processing the image sets is retained (1830) and superimposed over the correlated captured image (1840) .
- the shot location is compared with the zones of the selected view (e.g.
- Figure 19 to determine a score for the shot in question (1860) .
- Figure 19 is an illustration of how a view of a target and its kill zone is used for scoring.
- Figure 19 shows a portion of the displayed image corresponding to portion (810) of Figure 8. The target acquisition point

- the amount of elevation offset (drop or rise) for a projectile vis-a-vis the target acquisition point is determined
- FIG. 21 is a flow chart of an exemplary process for sighting in a DPI.
- the target acquisition point is placed directly on a bull's eye (2100) of a target.
- the trigger is squeezed and the image is captured (2110) as described above.
- the image data is processed using the scoring computer (2120) against known performance data to determine the actual target hit point. If the target hit point is not exactly on the bull's eye, the sight is adjusted (2130) as it would be with a normal weapon. The process is repeated until the hit location is adequately positioned with respect to the bull's eye in the judgement of the user (2140) .
