Description

Numeral sight and use it to the method for target following, locking and precision fire

Technical field

The present invention relates to a kind of novel shooting sighting device, particularly a kind ofly utilize high-definition image imaging, high-speed digital signal processes in real time, the shooting class of the principle design of mass data storage, ballistic trajectory database, Cloud Server and intelligent interconnection numeral aiming appliance device.

Background technology

Gun sight or title optical aiming device (optical sight) are vital devices in firearms device, use on a large scale now, developed very ripe from mid-term in 19th century.Current optical sight is mainly divided into three large classes: formula of looking in the distance gun sight (Telescopic sight), collimation formula gun sight (Collimating optical sight), reflex sight (Reflex sight), wherein with look in the distance formula gun sight and reflex sight the most popular.Above-mentioned two class gun sights mainly use by day, therefore white light gun sight (day scope/sight) is collectively referred to as again, also has the night sight (night scope/sight) for sighting at night in addition, add night-vision devices on above-mentioned two class gun sights, and press the kind of night-vision devices, not only can be divided into lll sight, sinperscope (but also active infrared and thermal imaging two class can be subdivided into).No matter any gun sight, main purpose be allow firearms user fast, accurately, hit easily, when therefore designing: accurate lock and to hit the mark be the core concept of gun sight.Now general optical sight development is very ripe, main two of its advantage: (1) convenient and graduation flexibly (Trajectory) is arranged so that user when in use can flexible positioning target and range finding.(2) lower price contributes to using on a large scale in firearms kind equipment.But the defect of traditional optical sight is also given prominence to very much:

1. the defect of graduation setting

Current optical sight is all calibrate graduation by the mode of the device of two on manual adjustment sight, one is made to control graduation transverse shifting, another be control graduation vertically move, both combinations regulate the position of graduation, make it with estimate in point of impact overlap.Regulating problem in the mobile existence two of graduation with these two devices: on the one hand two devices be no matter machinery or intelligence in the process controlling graduation movement, if use for a long time the wearing and tearing that cause in other words device own there is corrective error when dispatching from the factory and all can bring error to graduation control.Another one aspect regulates the pattern of graduation to be adjustment by a control device scale scale, scale itself is specified, like this on adjustment graduation point, it is a value set, and the bullet trajectory track of different firearms is unfixed, cause like this graduation in actual use cannot with point of impact inregister, and can only be " being similar to " overlap.This approximate coincidence at potential target relatively in firearms, error is not also very large, but in distant distance, such as more than 200 meters time, sizable error will be brought, make graduation and actual point of impact difference apart from far, so also just cannot bring the result of precision fire.The method of current this error of correction is lean on the shooting experience of ejaculator itself and make the estimation of bullet ballistic trajectory to make up substantially, once ejaculator changes, error just cannot make up.

2. optical magnification and to low illuminance environmental limit

Traditional optical sight is when being designed to have zoom function, and the formula sight of looking in the distance obtains enlarged image by the rotation adjusting focal length of enlargement ratio ring (Power Selector Ring).Be limited to its structure, the maximum amplification times yield (Magnification Ratio) that can accomplish civilian is at present 8X, and military can accomplish 16X ~ 20X, and only has little manufacturer to accomplish, cost is also very expensive.And reflecting sight is limited to its principle, high zoom multiplying power can not be accomplished.And the core concept of sight allows user amplify potential target exactly, clearly can observe the details needing the target of hitting, only have and clearly see that target could allow user's run-home thus bring condition to precision strike, and optical foresight is limited to the restriction of camera lens multiplication factor at present, target cannot be seen clearly in place far away, larger firing error can be brought like this.Simultaneously current optical sight is under low illuminance environment, and camera lens is not adaptive to the perceptibility of light, and only mixing night-vision devices could solve, and under the environment of low illuminance by day, mixes night-vision devices and seems and waste very much, and cost is also unable to stand.

3. the not storability of ballistic data

Traditional optical foresight is owing to can not store the ballistic trajectory data of ammunition, time each user will be shot, all need the position of the far and near Field adjustment graduation according to target, naked eyes judge target range simultaneously, estimate the point of impact that bullet is possible, regulate graduation and the approximate coincidence of point of impact.And this scene is according to the Distance geometry size of target, the mode of Field adjustment graduation and estimation point of impact is limited to the experience of ejaculator itself completely, if simultaneously also very familiar to firearms for there being the user of abundant shooting experience, to the words that ballistic trajectory is also understood very much, so use traditional optical foresight error can be smaller, and these experiences all need a large amount of exercises just can reach, when aiming, also psychological quality own also has much relations with ejaculator simultaneously, generally speaking, traditional optical foresight and people is used to there is great relation.

Larger defect is deposited for above-mentioned traditional optical foresight, in recent years, along with technology fast developments such as digital technology, Digital image technology, material technology, signal transacting, some professional quarters propose and devise digital sight (Digital Scope), and its core concept utilizes digital technology, nnir Rtorae technologies and image processing techniques to carry out alternative traditional optical sight.The device of numeral sight is that camera adds E-signal processor and adds the multi-order optical enlarging lens that display screen comes on alternative optical foresight substantially, stores the division device that adjustable graduation comes on alternative optical foresight on a processor simultaneously.Because digital sight is that purpose processor accurately controls graduation by image processing techniques, and the position of graduation is stored in by point of impact in the memory of non-loss in advance, if therefore mentality of designing is accurate, all defect of traditional optical sight substantially can be corrected.But due to the mistake of the defect in mentality of designing or design starting point own, cause digital sight existing at present to there is larger problem, mainly as follows:

1. graduation design existing defects

The graduation design of existing majority numeral sight allows user go from Row sum-equal matrix or to preset multiple graduation position, user is allowed to select voluntarily, and the trajectory parameter of firearms cannot be reflected in the position of graduation itself, the problem brought so does not fundamentally eliminate graduation and point of impact in traditional optical sight to be similar to the error of coincidence, and just allow camera and display screen instead of the camera lens of optical foresight.Under such design concept, in any case the color, size, thickness etc. of adjustment graduation all cannot change the fact that there is error between graduation position and actual bullet point of impact that display screen occurs.

2. ballistic trajectory data unicity

Existing some digital sights that have have been accomplished to allow graduation and point of impact overlap in graduation design, namely in advance point of impact is stored in internal memory, point of impact is obtained by actual test, then when run-home, allows graduation jump to point of impact and allows user's aimed fire.The thinking of this design graduation is accurately, but these digital sights are when storage ballistic data, only store a kind of bullet impact information, and point of impact number ratio is less (existing due to method of testing, ballistic error modification method, the restrictions such as memory span, generally maximumly only have about 20), cannot accurately to sketch out the complete ballistic trajectory of this bullet, when closer distance, often shoot more accurate, but more remote, after 500 meters, because bullet is by gravity effect, it is more severe that ballistic trajectory declines, if this time, the upward view angle of firearms was incorrect, firing error will be larger, equally also cannot accomplish the order ground of precision fire.And track, different bullet that the unicity storing data limits the shooting of same bullet different people use on firearms, the possibility of even shooting under varying environment.

3. there is comparatively big error and cannot accomplish real-time correcting process in ballistic trajectory data

Some existing digital sights allow user to remove the ballistic data of the bullet of the Internet download and oneself firearms coupling, be stored on local storage, then ballistic data error is calculated by additional computer, want the ballistic error being revised different distance place with plug-in computer by the mode of theory calculate, then carry out run-home with this revised ballistic data graduation point as a reference and use.This idea starting point is extraordinary, but Problems existing is at present: these bullet trajectory data are not often through strict test and checking, in use, use these ballistic trajectory data as with reference to graduation, the error larger with actual point of impact can be there is.The mode of plug-in computer disposal simultaneously, itself cannot accomplish process in real time, when after Subscriber Locked target, want to shoot immediately, especially some translational speeds ratio target faster, often moment just loses the chance effectively hit, if by outer computer, first sight needs by current target conditions to computer, then after computer disposal by result to sight, like this in the middle of lose the chance effectively hit.Therefore to the difference kind bullet of firearms conventional on market, test under difficult environmental conditions simultaneously, obtain accurate, complete ballistic trajectory database and shooting experience is not had to those, or the user of psychological quality less stable just seems extremely important, if simultaneously sight is by disposing high speed processor, by the real-time corrected trajectory parameter of algorithm modification method under various circumstances, the impact error of different distance point also will directly affect the result of precision fire.

4. cannot accomplish the quick tracking to target, automatically lock and precision fire

Existing all digital sight, owing to depositing defect in design, all really cannot be accomplished the quick tracking to target, automatically lock and precision strike object, is not therefore also intelligent digital sight truly.And why intelligent digital sight will have huge market in future, main cause utilizes high speed image signal transacting and data processing, and jumbo storage capacity, can be real accomplish quick tracking, automatic range, automatic aiming to target, automatically lock, thus realizing precision strike capability, similar self-navigation is the same at missile-borne guidance technology with Radar Technology.Make sight no longer rely on human factor like this, even if a people having no shooting experience is when use intelligent digital sight, as long as operate according to the rules, just can realize precision fire object.And existing digital sight is due to the many disadvantages in design, also this point cannot be accomplished.The present invention proposes a kind of novel digital sight apparatus, the network topology core texture of this device primarily of key element composition that the APP of digital sight, mobile terminal, Cloud Server and social networks four are large, thus construct one based on intelligent mobile interconnection technique, towards " the Internet of Things " (OSHN) of outdoor shooting and hunting.Numeral sight is primarily of: high definition and possess the camera of automatic or manual zoom capabilities, this camera also possess simultaneously stronger speed perception compared with the realtime graphic of the target under decreased light environment, high speed polycaryon processor process camera and other data, high-definition display screen, high accuracy touch-screen, there is range capability far away and possess the laser range sensor of degree of precision, wireless communication module, global location GPS module, jumbo non-loss memory, all kinds of can the sensor composition of real-time testing environment.The application program of APP major deployments on intelligent movable mobile phone or Mobile IP AD (panel computer) of mobile terminal, its function mainly realizes data retransmission in the wild and interim memory action.The effect of Cloud Server is exactly realize the effect such as the backup of data, the renewal of program.Core concept of the present invention allows user utilize digital sight to realize the quick tracking of goal, automatically lock and precision fire, its basic ideas are: with high-definition camera captured in real-time potential target, by laser range sensor real-time testing target range, determined the translational speed of target by " three limit positioning modes " with sensors such as gravity acceleration sensor, gyroscopes, record the data such as current wind speed and direction with air velocity transducer, these data are in real time stored in internal memory.User by display screen object observing, needed test storage in advance or downloads the ballistic trajectory data of conventional bullet of such firearms coupling from server, store in memory with database form before goal.When user determines that high-definition camera traces into target, and after laser range sensor accurately measures target range, just start LOCK locking, processor according to target range and recall coupling these distance ballistic trajectory data, each sensing data of Real-time Collection simultaneously, particularly " wind wafts " data, by the impact error of " trajectory parameter error is revised in real time and compensated " algorithm correction different distance, revised point of impact presents on a display screen with the form of graduation.Simultaneous processor can process captured in real-time view data, and allow graduation in screen center's place's display by image procossing mode, simultaneous processor automatically can drive the optical lens of camera, such that target is gem-pure on a display screen to be presented.User opens fire target, and because graduation is some display centered by the point of impact of revised actual bullet, therefore bullet accurately must hit the target area of graduation display.Due in this process, substantially artificial participation is not needed, user only needs the camera of digital sight to aim at the target that will hit, follow-up all with self run-home of digital gun sight, calculate target range, automatic focusing, automatically lock target, and striking point also can be very accurate, so just really achieve quick tracking to target, automatic aiming, automatically lock and the idea of precision strike.
