Description

TECHNICAL FIELD [0001] The present invention relates to an optical device using a ballistic zoom and a target aiming method.

This application is a continuation-in-part of US Non-Provisional Patent Application No. 13 / 412,506, filed March 5, 2012, and is a continuation-in-part of U.S. Patent Application No. 13 / 786,383 filed March 5, U.S. Patent Application No. 14 / 175,803, filed February 7, 2014, which is a PCT international patent application filed February 4, 2015, the content of which is incorporated herein by reference in its entirety do.

In the case of long-range firing with firearms, the shooter must first determine the foaming means (drop) based on the target (range), the bullet drop due to the flight characteristics of the bullet, and the distance to the side- Should be determined.

In general, the shooter would have memorized the values for each correction for falling and drifting at various ranges and wind speeds, or having charts attached to the side of his weapon. The shooter must then make corrections for each of these component values. Two methods are mainly used for this purpose. The first is to manually adjust the turrets on the optical aiming device so that the reticle directs the gun to the corrected target position. The second alternative is to use what is commonly referred to as "Holdover" There are many types of optical aiming devices for reticles that are scaled for this purpose. The shooter places the target at a different location on the reticle based on the scale.

There are numerous "optical means" for "automatic foaming means " However, it rarely survives in the market due to the high cost of automatically moving optical components and the difficulty of maintaining accuracy with repetitive shocks from weapons.

The aiming device or device of the first embodiment according to the present disclosure includes an image sensor and a lens for obtaining a video image of an object to which the aiming device is aiming, an image processor, a tilt sensor for sensing the force of gravity associated with the aiming device a tilt sensor, a display component for displaying video images processed by the image processor and captured by the image sensor, an eyepiece for allowing a user to view the display component, a pressure and temperature sensor for sensing atmospheric conditions, And suitable means for receiving the parts.

The device provides a complete "solid state digital" and "hands free" approach to precisely foaming weapons over long distances. By simply tilting the weapon left and right, the shooter can enter all the necessary information to make long-range firing at the point of firing without removing his hand from the weapon.

The preset critical angle defines the tilt function. For purposes of illustration, let's say this angle is 10 degrees. If the angle of inclination of the weapon is less than 10 degrees in any direction of the left or right side, the calculation for cross-drift adjustment is made. An indication of the amount of adjusted cross-drift is superimposed on the video image provided to the shooter with the appropriate cross-hair code defining the aim point. If the tilt angle is greater than 10 degrees in any direction, the range number superimposed on the video image gradually increases or decreases according to the direction and magnitude of the tilt angle greater than 10 degrees. The visual field, i.e. the magnification power of the video image provided to the shooter, is increased or decreased simultaneously with the number of ranges if the field of view is within the field of view defined by the front lens and the image sensor.

A range search circle is also superimposed on the video image. The circle represents a preset target size. The circle remains at a fixed size on the display part if the view is greater than the minimum. If the field of view is at a minimum, the range search original size is gradually adjusted to a smaller size in relation to the range setting. To explore the distance to the target, the shooter adjusts the range setting by tilting the weapon to the left or right by 10 degrees, until the target matches the range seeker.

As described above, the device provides a durable aiming device without visible external control. All the ballistic calculations necessary for long-range shooting are performed automatically in relation to internal sensors and settings by tilting the weapon. As a result, the use of the aiming device is made simple and easy.

In another embodiment according to the present disclosure, there is a digital sights instrument comprising a tubular housing having a central axis, a first end and a second end, and an interchangeable digital camera module carried by the first end of the housing. The camera module includes at least one focusing lens axially spaced from an image sensor mounted orthogonally to the lens axis on a sensor circuit board in a camera module. The image projected by the lens is focused at a predetermined position on the sensor. A control / display module with a longitudinal axis is removably secured to the second end of the housing. The control / display module is electrically connected to the camera module through a connector on the sensor circuit board of the camera module. The connection is made when the control / display module is installed at the second end of the housing. The control / display module includes a display portion having a control portion including a circuit board and a display component mounted thereon, and receiving the eyepiece assembly aligned with the display component.

The control portion of the control / display module preferably includes a power sensor, a tilt sensor, an external computer connector, an image processor, a memory, and a pair of sensors, all of which are connected to the printed circuit board on an axially oriented printed circuit board in the control / Lt; / RTI > The camera module and the control / display module are coaxially aligned in the tubular housing. The control / display module is configured to allow selection among pre-programmed parameters that can be set by the user when the control / display module is detached from the camera module and rotated about its longitudinal axis. The selection of one or more of the preprogrammed parameters is made by driving one or more of the pair of switches.

In the control / display module, the tilt sensor is configured to measure the tilt angle of the device with respect to the axis of the housing, and to cause the image processor to produce an adjusted target image in response to the measured tilt angle. The image processor is configured to generate a change in the display image field of view when an inclination angle greater than a critical angle is measured from the tilt sensor. An inclination angle greater than zero and less than the critical angle causes the deviation adjustment indicator to change position in the displayed image field of view.

The control / display module is configured to allow selection between pre-programmed parameters that can be set by the user when the control / display module is detached from the camera module and rotated about its longitudinal axis and held horizontally do.

Reference will now be made in detail to the accompanying drawings, which, at least, will help to explain the embodiments of the invention which are relevant to the novel technique presented by the present invention.

Referring now to FIG. 1, a digital sightsystem 100 of one embodiment is shown. In the illustrated embodiment, the system 100 includes an elongated, hollow, tubular housing 101 having a front end and a rear end. The housing may be made of anodized aluminum or the like. The front lens 102 and the image sensor 103 are mounted adjacent to the front end of the housing 101. [ The front lens 102 is mounted so as to focus light onto the image sensor 103 from a target. An image processor 104, a tilt sensor 105, and a battery 106 are mounted within the tubular housing 101. The image sensor 103 and the tilt sensor 105 are in electrical communication with the image processor 104 and the control / display module 108 and the image display component 109 are located adjacent to the rear end of the housing 101 Lt; / RTI > The image display component 109 is in electrical communication with the image processor 104. The housing 101 may also include a mounting system (not shown) embedded therein for the purpose of mounting the aiming device 100 on a weapon (e.g., a rifle gun).

In this exemplary embodiment, the image sensor 103 may be operable to obtain the original image data of the target. The image processor 104 may be operable to receive the original image data from the image sensor 103 and generate a target image based thereon. The image display component 109 may be operable to receive a target image from the image processor 104 and to display a target image to the user that may facilitate the aiming of the weapon.

The tilt sensor 105 may operate to measure the tilt angle of the aiming device 100 and generate respective position data based thereon. As used herein, "tilt angle" refers to the direction of rotation of the aiming device 100 with respect to the central axis of the tubular housing 101. The tilt angle is located on a horizontal axis that passes through the device from a reference direction (e.g., vertical) that is represented as a positive, and simultaneously (e.g., perpendicular), rotational displacement of the device (i.e., angular displacement). In one embodiment, the tilt sensor is an accelerometer. An eye sensor 110a disposed adjacent to eyepiece 110 and operative to communicate with the processor 104 may also be used as described herein.

The image processor 104 preferably includes a microprocessor and a microprocessor with software that can operate to receive the respective position data from the tilt sensor 105 and make adjustments to the target image display based thereon, And memory for storing information and dynamic information. Thus, by varying the tilt angle, for example, through the clockwise / counterclockwise rotation of the weapon attached to the aiming device 100, the weapon is either aimed or aimed along an axis passing through the barrel of the weapon, Lt; RTI ID = 0.0 > and / or < / RTI > In an alternative embodiment, this control and adjustment function of the tilt sensor can be replaced or supplemented with a button 105a, a switch, a knob, or other tool.

Static information stored in the image processor 104 memory includes the coordinates of the optical focus position on the image sensor 103. Since the image sensor 103 is a two-dimensional array of photosites known as pixels, the xy coordinates of the focus of the lens on the array define the reference position of the center of the image for display do. These coordinates are written into the nonvolatile memory of the image sensor.

In the embodiment shown in Figures 1 and 2, changing the tilt angle can control the aiming function such as field of view adjustment, drop correction, and / or drift correction. The critical inclination angle may define the separation function of the aiming apparatus 100. [ In one embodiment, the user can control the field of view of the target image display (i.e., effective magnification) by applying a tilt angle greater than the threshold tilt to the aiming device 100. When the tilt sensor 105 senses that the tilt angle is greater than the critical angle in any direction, the image processor 104 may respond by adjusting the field of view. The rate at which the field of view is increased or decreased, and so on, may depend on the direction and magnitude of the tilt angle.

In one embodiment, the critical tilt angle is 10 degrees. Thus, applying a tilt angle of 30 degrees to the right (i.e., clockwise) can cause the field of view to decrease rapidly (i.e., increase the magnification power), thereby causing the object to appear larger in the target image quickly to the user. Conversely, applying a tilt angle of 15 degrees to the left (i.e., counterclockwise) may cause the field of view to increase slowly (i.e., decrease the magnification power), thereby slowly causing objects in the target image to be smaller .

The field of view of the target image may have a limit determined by the resolution of the image sensor 103 and the resolution of the image display component 109. [ For example, the image sensor 103 may have a resolution of 2560 x 1920 pixels, and the image display component 109 may have a resolution of 320 x 240 pixels. The minimum field of view of the target image (i. E., The maximum magnification) can thus be reached when controlling the output of one pixel on the image display component 109 with data from one pixel on the image sensor 103. Therefore, at the maximum magnification in the present embodiment, the image display component 109 displays 1/8 of the data collected by the image sensor 103. [ The maximum field of view of the target image (i.e., the minimum magnification) is such that the image display component 109 with 320 x 240 pixels displays all of the data collected by the image sensor 103 with 2560 x 1920 pixels You can reach the case. Thus, at the minimum magnification in the presented embodiment, the data from the blocks of pixels collected by the image sensor 103 are combined in a process called "binning " To control one pixel. In order to perform a range search function with a high resolution, the target image must be gradually changed between a maximum and a minimum in small steps. Thus, the field of view of the image sensor 103 will change from 2560 x 1920 pixels to 320 x 240 pixels in a small step, and the resolution of the image displayed by the image display component 109 will remain fixed at 320 x 240 pixels will be. Thus, in one embodiment, the aiming device may have various magnification ratios from 8 to 1. Again, one or more buttons 105a, a knob, or a switch may be coupled with the tilt sensor 105 to perform the above-described adjustment as well.

Referring now to FIG. 2, one embodiment of a target image overlay 200 is shown. The microprocessor 104 may overlay the target image overlay 200 on a displayed target image. The target image overlay 200 displays information that can facilitate the aiming of the weapon to the user. 2, the target image overlay 200 includes a crosshair 201, a distance circle 202, a side airflow correction code 203, a number of ranges 204, and tick marks. (205). The retina 201 is used to define a collimation position within the target image. The range number 204 indicates the distance. The distance measurement units may be user selectable yards or meters. The crosswind correction code 203 together with the reference point 205 indicates the amount of side wind corrected to miles per hour or kilometer per hour. If the optional imperial unit is selected, then the overlay 200 is being corrected, as shown, for a 3 mile per hour coming from the right, and the calculated bullet drop for the distance to the target of 525 yards is corrected .

The illustrated target image overlay 200 includes a distance measurement element 202. In the illustrated embodiment, the distance measurement element 202 may be a distance circle, but other element shapes may be used. The aiming device 100 can measure the distance (i.e., range) to the target through a " stadiametric method "using the distance circle 202. [ The distance circle 202 represents a preset target size. While the size of the distance circle 202 is kept constant, the image of the target appears to fill the distance circle (e.g., at an angle of inclination greater than 10 degrees) The field of view can be adjusted. Alternatively, if provided on the aiming apparatus 100, the button 105a may be depressed, and the turret may be rotated or the like. The image processor 104 may then calculate the distance to the target using trigonometry. For example, three points consisting of the visible head of the target, the visible bottom of the target, and the front lens 120 define a right triangle. The distance from the top to the bottom of the target defines the first side of the triangle. The distance circle provides a measurement of an angle to the first surface. Thus, the image processor 104 may calculate the distance of the adjacent side of the triangle, i.e., the distance to the target.

At a very long distance to the target, the image of the target may not be large enough to fill the distance circle 202 even at maximum magnification (i.e., even in the minimum field of view). Thus, in one embodiment, when a maximum magnification is reached, the image processor 104 may be responsive to successive inputs to reduce the field of view (e.g., at an angle beyond the threshold angle) ), It may begin to reduce the size of the distance circle 202. Thus, the range search can be facilitated even at a distance exceeding the maximum magnification. This process is further described below.

The effect of gravity on the bullet (i. E., The bullet drop) can be calculated and corrected by the image microprocessor 104 based on variables such as the range associated with the bullet and the ballistic data. The ballistic data may be input to the aiming device 100 and stored. Examples of such inputs are further described below with reference to additional exemplary embodiments. To facilitate bullet drop correction, the image processor 104 may move the target image up relative to the reticle 201, based on the calculated bullet drop, thereby causing the observer to < RTI ID = 0.0 > Even if it appears to be in the center, the shooter can effectively aim at the spot on the target. In another embodiment described below, the image processor 104 may display a region of interest for the launch vehicle at a specific distance from the shooter. The shooter will then be required to raise the weapon to align the crosshairs on the target. This action compensates for bullet drops at some point along the launch path.

The influence of the wind on the bullet (i. E., Cross-windage) can be measured by the image processor 104 based on such parameters as the range, the ballistic data, Can be calculated and corrected. The ambient wind conditions can be measured and estimated using techniques known in the art. The cross-drift may be input to the image processor 104 by applying an appropriate tilt angle to the aiming device 100. [ To facilitate cross-drift correction, the image processor 104 may move the target image horizontally relative to the reticle 201, based on computed or known cross-drift, To target the wind of the target at an opposite point, and in another embodiment described below, the image processor 104 may display a region of interest for the launch vehicle at a specific distance based on the cross-drift. Then the shooter will be required to move the weapon to align the crosshairs on the target. This operation compensates for cross-drift at some point along the launch path.

The user can control the cross-drift correction function by applying an inclination angle smaller than the critical angle of the aiming apparatus 100. [ The magnitude and direction of the tilt applied to the aiming device 100 can control the magnitude and direction of the cross-drift input, thus controlling the cross-drift correction. For example, if the critical tilt angle is 10 degrees, a tilt angle of 5 degrees to the right (i.e., clockwise) may correspond to a cross-drift correction suitable to compensate for 10 mph of wind blowing from the user's right. On the other hand, a tilt angle of 3 degrees to the left (ie, counterclockwise) can accommodate the appropriate cross-drift adjustment to compensate for a wind of 7 mph blowing from the left.

The crosswalk correction code 203 can facilitate cross-drift correction by allowing the user to more accurately enter the cross-drift. The image processor 104 may cause the lateral wind correction code 203 to slide left and right relative to the reticle 201 in response to the magnitude and direction of the tilt angle, The magnitude and direction of the cross-drift input being communicated to the user.

Also, the image processor 104 may determine that the target is located on the left side of the target image centered on the crosshairs, even though the direction toward which the weapon's gaze is directed is corrected for the cross- . For example, in the embodiment shown in Figure 2, the side airfoil code 203 represents a right-to-left cross-drift input of three units (e.g., mph) The inorganic barrel alignment is automatically adjusted to the right with a 3 MPH crosswind. Therefore, the shooter must maintain a 3-unit tilt during the foaming of the weapon to automatically correct for crosswinds. In an alternative embodiment, the tilt does not need to be maintained, since the shooter can return the firearm to a vertically erected position prior to foaming.

Must first be mounted on the weapon and "sighted in" at known distances to initially align the device 100 on a weapon, such as a rifle gun. A series of operating steps is briefly described in Fig. This process is used to compensate the device for mechanical alignment changes to the inorganic barrel. The first vertical adjustment is referred to as a correction for mechanical "elevation" to the reference distance. Generally for a rifle this is done at a target distance of 100 yards. The second adjustment is to compensate for horizontal variations in mounting and is referred to as mechanical "drift ". For the device 100, this adjustment may be made in software on an external device, such as a portable computer, iPad, smart phone or PC, connected to the microprocessor 104 in the device 100.

The initial default values, assuming a perfect barrel alignment, and the expected porosity (MV) value and the anticipated ballistic constant (BC) are determined by the device 100, as shown in act 1101, As a default. Next, the weapon starts at a target range, with the target located at a known distance, e.g., 100 yards, and the device 100 is aimed at the target at act 1102. Preferably, this is done in the absence of a side-effect that affects the correction being made. Then, in act 1103, a first test shot is fired (without tilt) into the apparatus 100, and the crosshairs are aimed to be centered on the target image. In act 1104, bullet impact deviations from the target center are measured and recorded. In act 1105, a second test shot is made, and in act 1106 the bullet impact deviation from the target center is recorded. In act 1107, these test shots are repeated a number of times. In the act 1108, all of these recorded deviation values are input to the software to generate the mechanical up and down adjustment and drift correction values of the device 100 to a particular weapon. Lastly, in operation 1109, the software whose up-down adjustment and drift correction values are determined for the device 100 is downloaded to the scope device 100 through the USB port.

Additional test shots of varying distances are needed to provide appropriate ball speed (MV) and ballistic constant (BC) data tailored to the weapon. This operation step is described with reference to Fig. These steps are the same as those in Fig. 19 up to step 1208. Fig. In act 1209, the preceding steps are repeated for several different target distances. The deviation is then input to the software at act 1210 to produce the best fit data by producing accurate ball speed and ballistic constant data for the particular cartridge being fired in the weapon. These values are then downloaded to the device 100 in act 1211.

The software code used to generate the MV and BC data is based on Newton's physics eccentrics for well-known projectiles. An exemplary equation for this purpose is described in J. Can be found in J. Pejsa, Kenwood publication Modern Practical Ballistics, 2nd edition. Once these values of MV and BC are known for a particular weapon / collimator combination, they are downloaded to the image processor 104 and the operation of the device 100 is simplified.

In operation, the user of the apparatus 100 can simply aim the weapon at the target, tilt the weapon more than 10 degrees counter-clockwise to visually zoom in on the target, When it is large, it returns the weapon vertically and tilts the weapon either slightly to the left or right depending on the perceived crosswalk, and foams. The range is automatically corrected through a microprocessor moving the display image up or down. The crosshairs are kept centered, and the range correction is automatically provided and displayed. The cross-drift correction is accomplished automatically by the gunner tilting the gun to his or her prediction of the desired target offset provided by the cross-air correction code 203 in the image display shown in FIG. The target image is automatically moved from the display to the right or left in the display to aim at the displayed image with the crosshair remaining in the center and the shooter centered on the displayed crosshair, foaming is performed while maintaining the desired tilt, do.

Referring now to Figures 3-4, a second embodiment of the aiming device 300 is shown.

The interchangeable camera module feature allows one aiming device or device 300 to be used in a variety of different environments, such as long-haul or short-haul situations, without having to sit back on another camera module 319. This can be very beneficial to the user.

The collar 307 may be any suitable mounting system capable of maintaining a mechanical connection between the control / display module 308 and the tubular housing 301 during bayonet type, threaded or foaming of the weapon Can be applied.

The front opening of the collar 307 is aligned with the outer surface of the rear end of the tubular housing 301. The outer surface of the rear end of the tubular housing 301, in this exemplary embodiment, comprises an annular groove. The inner surface of the collar 307 includes an annular rib configured to fit within the groove such that the collar 307 is rotatably mounted to the tubular housing 301. The inner surface of the rear opening of collar 307 is threaded. The control / display module 308 is threadably coupled to the tubular housing 301 through the rotation of the collar 307. The control / It can be mounted threadably. Thus, the collar 307 allows the control / display module 308 to be connected to or disconnected from the tubular housing 301 without rotation of the control / display module 308 relative to the tubular housing 301 . This in turn enables the use of a bayonet-type electrical connection or plug between the control / display module 308 and the camera module 319.

The control / display module 308 includes an eyepiece assembly 310. The eyepiece assembly 310 facilitates viewing of the image display component 309. In one embodiment, the distance from the eyepiece to the image display component 309 in the eyepiece assembly 310 may be manually adjustable to facilitate diopter adjustment. For example, the eyepiece assembly 310 may be configured such that the clockwise rotation of the eyepiece assembly 310 increases or decreases the distance from the eyepiece to the image display component 309, / Display module 308, as shown in FIG.

8, the control / display module 308 is mounted with a battery 306, a tilt sensor, a pressure sensor, and a temperature sensor, and then the display portion 315 of the control / display module 308, And a control unit 313 including a circuit board 326 connected to the microprocessor 304 connected to the display element 309. The control unit 313 includes a microprocessor 304, In the case where the control / display module 308 is installed in the housing 301 as described above, the microprocessor 304 mounted on the circuit board 326, And a male bladed connector 322 fastened to the female connector 324 for rigidly connecting the image sensor 303.

Displacement of the control / display module 308 from the tubular housing 301 allows the user to enter information to be stored in the electronic memory of the microprocessor 304. This information may include, for example, the ballistic data, which are the ballistic constants associated with ambient temperature, pressure, porosity, drag, and / or one or more bullet types. The removal of the control / display module 308 from the tubular housing 301 may be accomplished by a computer connection port 312 electrically connected to the processor 304 via a circuit board 326, . In one embodiment, the computer connection port 312 is a USB port. The control / display module 308 may be coupled to a computer having appropriate application software that is capable of communicating with the processor 304 via a computer connection port 312. [ The ballistics data for one or more of the bullet cartridge types may then be transmitted to the aiming device 300 for use in connection with the bullet ballistics used in the field by the processor 304 to facilitate the aiming of the weapon, Stored and input.

Turning now to FIG. 9, an embodiment of a replaceable lens module 319 is shown. In the illustrated embodiment, the lens module includes a lens barrel 320 having a mating surface 321. In this embodiment, The mating surface 321 facilitates proper alignment of the interchangeable lens module 319 in the housing 301. As described above, the image sensor 303 preferably includes a non-volatile memory. (X, y) of the pixels in the array of pixels of the image sensor 303 lying along the line of sight of the camera module 319 (referred to herein as a "reference pixel & Store the coordinates. When the interchangeable lens module 319 is installed in the device 300, the microprocessor 304 may be enabled to read the coordinates of the reference pixel to establish reference points of the target image. Thus, each of the interchangeable lens modules 319, which may be installed in the device 300, is self-contained and sealed. In addition, the variable features described herein are not affected by changes in the camera module 319.

Due to some manufacturing defects (e.g., lens defects), the line of sight of the camera module 319 may not exactly coincide with the longitudinal center axis of the camera module 319. Preferably, the reference pixel is determined at a final stage in the manufacture of the lens module 319. In order to determine the reference pixel, the interchangeable lens module 319 may be connected to a calibration device (not shown) including surfaces that mate with the mating surfaces 321. The calibration device further includes a calibration target positioned such that the center axis of the lens module (319) points to the calibration target when the interchangeable lens module (319) is mounted on the calibration device. Then, the image of the calibration target can be obtained through the sensor 303. [ The reference pixel can then be located by determining which pixels of the sensor 303 the light emitted from the calibration target is captured and analyzing the image. The coordinates of the reference pixel may then be stored (e. G., "Burned") in the non-volatile memory of the image sensor 303 via the calibration device.

Referring now to FIG. 10, there are shown four exemplary menu screens provided by the control / display module of the digital sights. In one embodiment of the control / display module 308, the separation of the control / display module 308 from the tubular housing 301 allows the user to control the size of the distance circle 202, the maximum zoom range, Allowing you to select features in-the-field.

These functions are preferably organized into menus. For example, the cartridge menu may display several cartridge types. Changing the cartridge type on the menu allows the ballistics data, which are the MV and BC values used by the processor 304 to calculate the trajectory, to change accordingly.

In one embodiment, the user may go through various menus by changing the tilt angle of the separate control / display module 308. [ For example, the first menu may be viewed at an oblique angle of 0 degrees, the second menu may be viewed at an oblique angle of 90 degrees, the third menu may be viewed at an oblique angle of 180 degrees, and the fourth menu may be provided at an oblique angle of 270 degrees. The user may go through various options within each menu through the use of push buttons 314, Thus, the user can change these functions in the field, such as the size of the distance circle 202, the maximum zoom range, and the ballistic data associated with one or more cartridge types. In one embodiment, the eye sensor described above can be used to go through the steps of navigating through the menus. The eye sensor registers specific intentional movements of the eye and can adjust the selection of the corresponding menu. For example, the eye sensor may register a motion of the eye in a downward direction, and the processor may signal a signal to highlight a menu selection under the previous menu selection. Eye movement to the left or right can let you toggle the selection on or off. Also, an intentional blink of an eye, for example, which has a duration longer than a preset time, can be used to select or clear the option. Actions taken by other eye movements are also considered.

Turning on the aiming device 100 or 300 may preferably be performed by removing the front cover lens (not shown) from the aiming device. Placing the aiming device in a low power standby state can be performed by rearranging the front lens on the aiming device. Of course, removing the battery will make the device unavailable, but static information stored in nonvolatile memory will not be erased.

In addition, the techniques described herein can be used in a collimation or optical device to indicate the position of a projectile along its trajectory curve by increasing or decreasing the zoom level. An exemplary situation is illustrated in FIG. As described above, when the bullet is moved from the rifle gun to the intended target, several forces affect the flight of the bullet. Gravity causes the bullet to fall at an altitude while the bullet is moving away from the target's firearm. If the hunter 500 approaches his / her target 502, the bullet drops very little. This trajectory approaches the optical path 504 at a short distance. However, improvements in firearms and ammunition allow the hunter to target hunting from long distances. At these longer distances, gravity causes the apparent drop in the altitude of the bullet, as indicated by the trajectory path 506 in FIG. In addition, other factors affect the flight of the bullet. For example, a crosswind causes a bullet to move horizontally along the bullet's flight path. Compensation of the optics for the wind, which affects the flight of the bullet, is often referred to as drift. Humidity, altitude, temperature, and other environmental factors can also affect the flight of the bullet.

In order to appropriately aim the target from a clear distance, a general optical device (i. E., Optics that use a plurality of lenses along the optical path, without an image sensor) adjusts to increase the magnification along the optical path of the device . That is, an increase in magnification increases the visible size of the target along the line of sight between the aiming device and the target. However, in order to compensate for the bullet drop, the user must adjust the position of the target in the viewfinder by slightly raising the firearm, thereby aligning other aiming elements on the target based on the range for that. This extra step is often forgotten by a novice or distracted novice (or even a skilled novice), resulting in inaccurate aiming. This can lead to misfire, or, more severely, nonflammable foaming. In the so-called "trajectory zoom" technique described below, the aiming device displays the area for the firing position at any given distance from the shooter, and thus the shooter raises, drops, or otherwise You may want to pay attention to adjusting the position.

The trajectory zoom techniques described herein differ from the prior art in that an increase in magnification (or zoom) occurs along the trajectory path 506 of the bullet. For any known ballistic information (e.g., firing diameter, perimeter velocity, crosswind velocity, etc.), the firing position is known as the distance from the firearm. The techniques referred to herein are rapidly zoomed in or out along the trajectory path 506 as shown in FIG. The aiming device 508 captures a field of view (FOV) (indicated by lines 510). The aiming device 508, however, displays only a portion of the view 510 to the user. (Also referred to as the region of interest (ROI)) is the view area around the launch location. A plurality of regions of interest 512 are shown in FIG. For example, 0 yard (512a) from the aiming device is the area around the launch vehicle at that point in space. The area of interest is shown at 200 yards (512b), 400 yards (512b), 600 yards (512c), and 800 yards (512d). A zoom value (described further below) is associated with the ballistic curve, thus allowing the aiming device 508 to determine the magnification for a given range and vice versa. The marked area of interest 512 may be any area desired or desired for a particular application. As the bullet falls along the trajectory path 506, the hunter 500 is focused to raise the firearm to maintain the properly positioned indicated collimation element on the target 502.

Figures 12a-12c illustrate a captured view-to-view display screen for a navigation device using ballistic zoom techniques at various zoom levels. Image conduction captured by use of lenses in the aiming device is not shown. 12A shows an image 600 captured by an image sensor, such as a camera. Mainly, the image 600 is the full view of the sensor (FOV). A region of interest (ROI) 602 is provided to the shooter as the image 604 displayed on the display. In this figure, the region of interest (ROI) 602 is the entire captured image 600. A collimation element 606, such as crosshairs, is superimposed on the displayed image 604. The crosshairs 606 indicate that the bullet is located at a particular distance from the aiming device and the zoom level of the aiming device in relation to that particular distance. The distance measurement element 608 is in this case in the form of a distance circle and is also superimposed on the displayed image 604.

At all zoom levels, including the maximum zoom level, the displayed size of distance measurement element 608 has the same size for field of view (FOV) 600 and is calibrated to a known target size. Thus, when using a calibrated distance measuring element with a six-foot target, once the target "fits" (by increasing the magnification) within the distance measuring element, the aiming device can, The range up to the target can be calculated based on the stadiametic method. Unlike conventional devices that increase magnification along the optical path, the ballistic zoom technique increases the magnification along the trajectory path. Accordingly, the displayed image 604 may be displayed on the lower portion of the field of view (FOV) 600 as the zoom level increases as the ballistic path decreases as the distance from the firearm increases. . For example, FIG. 12B shows the relationship at the 4x zoom level. Here, the captured image or field of view (FOV) 600 does not change from FIG. 12A. The ROI 602 is smaller than the total field of view 600 and is located close to the lower region of the field of view 600. The region of interest (ROI) 602 is displayed as the displayed image 604. The size and location of the aiming element 606 and the distance measuring element 608 remain unchanged on the display. 12C shows the relationship at the 8x zoom level. Again, the captured image or field of view (FOV) 600 does not change from FIG. 12A. The ROI 602 is smaller than the field of view 600 and is located below the field of view 600. The sensor resolution can be scaled to the display resolution by pixel binning or other techniques known in the art. As the power of the zoom increases, a much smaller region of interest (ROI) 602 is displayed. In addition, since the magnification follows the ballistic path, the ROI 602 is always centered on the position of the bullet with respect to the range associated with that particular zoom level. This helps ensure to fire at the correct distance.

13A shows a region of interest for various magnifications of a conventional optical zoom system. In a conventional zoom system, the magnification is centered on the field of view (FOV), and the region of interest (ROI) corresponds to the portion located at the center of the field of view (FOV). Thus, at even greater distances, the user must arrange different aiming elements relative to the target to ensure accurate foaming. Additionally, from the perspective of the displayed side wind, the user must also use drift aiming elements to compensate for side wind, in which case the user must aim the firearm left to compensate for the moving wind from the right.

In contrast, FIG. 13B shows a region of interest for various magnifications of the ballistic zoom system. Here, the center of the ROI follows a ballistic curve of the bullet, such that the position of the bullet at all zoom levels is centered on the region of interest (ROI). As the zoom level increases, the center of the ROI moves down along the calculated bullet drop and moves horizontally according to the drift of the calculated bullet due to the cross wind. This allows the user to center one of the available aiming points on the target to facilitate accurate foaming.

Figure 14 shows the relationship between the field of view and a fixed size distance measurement element. The aiming device 700 is shown having a field of view (FOV) (defined by the outermost lines 702). The inner lines 704 represent the distance measure element scale in relation to the field of view (FOV) 702. The field of view (FOV) angle is known as any zoom level. As a result, the distance measurement element 704 ranges the known distance measurement element angle? At any zoom level. The user may select from the distance measurement elements sized to a particular target 706 size. For example, a user may have a corresponding circle at a known distance to a target of a certain size (e.g., a 6 foot target for an elk or other large prey, or a 3 foot target for a wild pig or a smaller prey) Can be selected. Since there is only one range R in which the target 706 is accurately bound by the distance measurement element 704, the aiming device 700 can determine the range R based on the zoom level . The aiming device performs calculations to determine the range R for the target 706. [ This range is used to calculate the position of the ballistics and the region of interest (ROI). The range R may also be displayed along with zoom level, cross wind speed, or other information.

Figures 15-18 illustrate a method of aiming a target according to some embodiments. 15 shows a first method 800 of aiming a target with a sighting or optical device. The method 800 begins with an act 802 that receives an initial condition of the optical device. The initial condition may include the size of the distance measuring element as well as the range associated with the distance measuring element. For example, the distance measurement element may be based on a target of say 6 feet and may be selected by the user depending on the expected target size. The processor of the aiming device associates a known distance measurement element with a known range, and the range of the target that fits within the distance measurement element is known. Ballistic information such as muzzle exit speed, launch vehicle weight or type, crosswalk velocity and direction, atmospheric pressure, tilt, tilt, ambient temperature, and other information are received at act 804. In general, the vast majority of this information is programmed into the storage element of the aiming device before use, although the cross wind speed is primarily set during use. An image that is primarily in the field of view (FOV) is received by the image sensor in act 806. An ROI, which is at least a portion of the image, is displayed on the display to the user at act 810. Thereafter, a first zoom input may be received in actuation step 812, and a first zoom level is set. The zoom level corresponds to a known distance from the aiming device. The zoom input may be based on an action taken on a portion of the user, e.g., actuation of a button or knob, tilting of the firearm, and the like. As the aiming device increases the zoom level, the firing position at its known distance (or zoom level) is determined at act 814, with associated ballistic information. Based on the zoom value and the firing position, a region of interest (ROI) around the location of the projectile may be displayed in an actuation step 816. Although the marked crosshairs can be used for aiming, the aiming device can display the same sign as the sighting element at the intersection of the crosshairs to further emphasize the firing position.

16 illustrates a method 850 of aiming a target once the maximum zoom level of the image sensor has been reached. This condition may occur when the target is extremely far from the aiming device user and the aiming device reaches the maximum zoom level after performing the method 800 shown in FIG. 15, for example. The method 850 begins in act 852 by receiving a maximum zoom level setting a maximum zoom level. The maximum zoom level may be defined by the image sensor ROI and the displayed image, for example once the resolution of the image sensor ROI matches the resolution of the displayed image. The maximally enlarged image is displayed in an act 854. Thereafter, the second zoom input sets the second zoom value in act 856. [ Unlike the method 800 described above, after reaching the maximum zoom value, the additional zoom input reduces the displayed size of the distance measurement element. Based on the zoom input or zoom level, the size of the distance measurement element is calculated in act 858. The adjusted distance measurement element is then superimposed on the maximally enlarged image in actuation step 860. [ As the zoom input of the aiming device increases, the firing position at its known distance (or zoom level) is determined at act 862, with associated ballistic information. Based on the zoom value and the firing position, a region of interest primarily around the location of the firing can be displayed as in act 864. As with method 800 of FIG. 15, the aiming device may display the same sign as the aiming element to further highlight the firing position.

17 shows a method 900 for aiming a target. The method 500 includes receiving ballistic information that may be stored in memory in whole or in part. An image is received from the image sensor in act 904. A zoom value is received at act 906, and a shot balloon is calculated at act 908. [ As in the above-described method, a ROI based on the zoom value is displayed in act 910. Primarily, the region of interest (ROI) corresponds to at least a portion of the firing position. Although the marked crosshairs can be used for aiming, the aiming device can display the same sign as the sighting element at the intersection of the crosshairs to further emphasize the firing position. By superimposing the distance measurement element on a portion of the displayed image, a range of targets can be determined in act 912. Other methods of determining the range may also be used. Once the zoom input is received by the user's actuation, such as, for example, a button, tilt of the aiming device, in an actuation step 914, an updated ROI may be displayed in act 916.

Another method 1000 for aiming the target is shown in FIG. Here, an image received by an image sensor, such as a camera, is received in operation step 1002. A field of view, which is part of the received image, is displayed in act 1004. A distance measurement element having a fixed size in relation to the displayed field of view is displayed or superimposed on the field of view in act 1006. [ Target size input is received in act 1008. The target size input may be a default target size input (e.g., for a 6 foot high target), or the input may be received from a storage device. In another embodiment, the target size input is selected from a plurality of predetermined target sizes. A zoom input setting a zoom value is received at act 1010, and then a range for the target is calculated at action 1012. [

The ballistic zoom technique described herein can be used for a collimating device using an image sensor such as a camera. In certain embodiments, the use of a trajectory zoom may be selected as an option, instead of a normal or default zoom, as described above (i.e., the zoom level or magnification is a zoom system that increases along the optical path). Thus, the shooter may change the preferred (ballistic or general) zoom system for particular scenarios, user preferences, and the like. In still other embodiments, the optical device settings may be selected, for example, when the crosshairs shown in Figures 12A-12C are not associated with the firing position. In such embodiments, the display may display one or more aiming elements, separate from the crosshairs, associated with the firing positions at a given distance. The ROI may be centered on the aiming element in these embodiments.

19 and 20, the aiming device 300 can be aimed at each of up to four types of cartridge / bullet combinations for use in a weapon. In order to initially align the aiming device 300 on a weapon such as a rifle, as in the first embodiment described above, it must first be mounted on the weapon and "sited" to a known distance. A series of operating steps are summarized in FIG. This process is used to compensate the device for mechanical alignment variables for the inorganic barrel. The first vertical adjustment is referred to as a correction to a mechanical "bullet drop" at the reference distance. For primarily rifles, this is done at a target distance of 100 yards. A second adjustment to compensate for horizontal variables in the mount is referred to as mechanical "drift ". For the device 300, such adjustment may be made in software located on an external device such as a portable computer, iPad, smart phone or PC, and then may be stored on the control / display module 308 Is downloaded from the device 300 to the microprocessor 304 via the USB port 312.

Initially, the default values assuming full barrel alignment, the expected porosity (MV) values and the expected ballistic constant (BC) are set to the device 300 as shown in act 1101 of FIG. . Next, the weapon is taken for a target range that is located at a known distance, for example, 100 yards, and the device 300 is aimed at its target at act 1102. Preferably, this is done if there is no tangent affecting the correction being made. Then, in act 1103, the first test shot is fired into device 300 that is essentially horizontally aimed (without tilt) and held vertically so that the crosshairs are centered on the target image. At act 1104, the bullet impact deviation from the target center is measured and recorded. A second test shot is performed in act 1105 and a bullet impact deviation is recorded in act 1106 from the target center. These test shots are repeated several times in act 1107. In act 1108, these recorded deviation values are all entered into the software to cause mechanical up-down and drift correction for the instrument 300 on the weapon. Finally, in act 1109, the software for which the vertical adjustment and drift correction values for the device have been determined is downloaded to scope device 300 via the USB port.

Additional test shots at various distances are needed to provide appropriate perimeter (MV) and ballistic constant (BC) data that are precisely matched to the weapon. These operating steps are described with reference to Fig. These steps are the same as those in FIG. 19 up to the step 1208. In act 1209 the previous steps are repeated for several different distances. The deviations are then input into the software at act 1210 to generate accurate ball speed and ballistic constant data for the particular cartridge being fired in the weapon and to generate an optimal value of the data. These values are then downloaded to the device 300 in act 1211.

This procedure, as described with reference to Figure 20, then has to be repeated for up to four different cartridge load / bullet combinations, as MV and BC values may be different for each combination. Once this process is complete, the device 300 will "learn " the exact pore velocity and ballistic constants needed for the correct operation of the aiming device 300. In order to perform an accurate cross-drift correction calculation, it is necessary to know the range, tilt, MV, BC, wheat air density values. The range is set manually by tilting the weapon and the device 300 at an angle greater than, for example, 10 degrees, until the image of the target properly fills the image source on the display. The gun then turns back, if it is smaller than 10 degrees, perhaps if there is no flank at the time of firing. If there is a tide, the shooter simply tilts and re-aims appropriately and fires in accordance with the crossed lines 201 and crosswalk correction codes 203 in the displayed image. Both temperature and atmospheric pressure are important for an accurate determination of air density.

It is important to understand that when the control / display module 308 is installed in the housing 301, the temperature and pressure values no longer accurately reflect the environmental conditions. Therefore, the control / display module should not be installed up to the foaming site or at least temporarily removed so that it can be reflected to the appropriate temperature and pressure when at least the foaming place is reached. Once the foam location is reached, the user can remove and reset the batteries 306 to reset the control / display module 308, thereby allowing the control / display module 308 to re- Allow pressure and temperature values to be measured and stored before installation. Due to the contacts 322, when the control / display module is fully installed, the microprocessor 304 sensing both the sensor 303 and its microprocessor and the camera module 319 is connected, Once removed, you will know the current video.

In operation, a user of one of the devices 100 or 300 may simply aim the weapon at the target and tilt the weapon by more than 10 degrees counterclockwise to visually zoom onto the target, If it is the right size, return the weapon to the vertical and tilt the weapon slightly left or right, depending on the perceived crosswalk, and fire. The range is automatically corrected through the microprocessor by moving the display image up or down as appropriate for the bullet drop. The crosshairs remain centered, and range correction is provided automatically. In addition, the cross-drift correction is accomplished automatically by tilting the instrument at an angle less than 10 degrees, corresponding to the crosswind measured, and aiming the target directly at the crosshairs. This tilt causes the display image to move to the right or left, so that the correct aim remains centered on the crosshairs. The cross-drift correction is shown as an indicator 203 in the display image shown in FIG.

Thus, it is a digital aiming device of the original structure and concept shown and described.
