Description

Numeral sight and use its method to target following, locking and precision fire

Technical field

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

Background technology

Gun sight or to claim optical aiming device (optical sight) be in firearms device vital one Device, starts large-scale use till now from mid-term in 19th century, has developed the most ripe.Optical laying at present Mirror is broadly divided into three big classes: formula of looking in the distance gun sight (Telescopic sight), collimation formula gun sight (Collimating optical sight), reflex sight (Reflex sight), wherein to look in the distance Formula gun sight and reflex sight are the most popular.Above-mentioned two class gun sights use the most by day, the most again by It is referred to as white light gun sight (day scope/sight), additionally also has the night sight for sighting at night (night scope/sight), is plus night-vision devices on above-mentioned two class gun sights, and presses night-vision devices Kind, not only can be divided into lll sight, sinperscope (but also can be subdivided into active infrared and thermal imaging two class). The most any gun sight, main purpose is to allow firearms user hit quick, accurate, convenient, because of The when of this design: accurate lock and to hit the mark be the core concept of gun sight.Optical laying generally used now Mirror development is the most ripe, main two of its advantage: (1) graduation (Trajectory) conveniently and flexibly Setting makes the user when in use can be with flexible positioning target and range finding.(2) relatively low price contributes to Large-scale use in firearms kind equipment.But the defect of traditional optical sight highlights the most very much:

1. the defect that graduation is arranged

Current optical sight is all to calibrate graduation by the mode of two devices on manual adjustment sight, Making one to control graduation transverse shifting, another is to control graduation to vertically move, and both regulate graduation at combination Position, be allowed to estimate in point of impact overlap.In the mobile existence two with the regulation graduation of the two device Aspect problem: on the one hand two devices either machinery or intelligence are controlling during graduation moves, if Using the most own device of abrasion caused to there is corrective error dispatching from the factory when for a long time all can be to dividing Draw control and bring error.Another one aspect be regulation graduation pattern be by control one scale of device one The regulation of scale, scale itself is specified, so on regulation graduation point, is a value set, and The bullet trajectory track of different firearms is unfixed, so cause graduation in actual use cannot and bullet Some inregister, and can only be that " approximation " overlaps.This approximation overlaps and relativelys close to firearms at potential target When, error is not the most very big, but in distant distance, the when of such as more than 200 meters, will Bring sizable error so that graduation and actual point of impact differ apart from far, the most just cannot bring essence The really result of shooting.Revise at present the method for this error and be substantially the shooting experience by ejaculator itself and right The estimation of bullet trajectory track is made and being made up, and once ejaculator changes, and error just cannot make up.

2. optical magnification and the restriction to low illuminance environment

Traditional optical sight is when being designed as having zoom function, and the formula sight of looking in the distance is to pass through enlargement ratio The rotation adjusting focal length of ring (Power Selector Ring) obtains enlarged drawing picture.It is limited to its structure, mesh The front civilian maximum amplification times yield (Magnification Ratio) that can accomplish is 8X, and military can do To 16X～20X, and the most little manufacturer can accomplish, cost is the most much more expensive.And reflecting sight It is limited to its principle, it is impossible to accomplish high zoom multiplying power.And the core concept of sight to allow user amplify exactly latent In target, it is possible to clear observe the details of target needing to hit, only it is clearly apparent target and could allow user Run-home thus bring condition to precision strike, and optical foresight is limited to the limit of camera lens multiplication factor at present System, it is impossible to see target in place farther out, so can bring bigger firing error.The most current light Sight is under low illuminance environment, and camera lens is not adaptive to the perceptibility of light, only mixes night vision dress Put and could solve, and in the environment of the lowest illuminance, mix night-vision devices and seem and waste very much, and cost On be 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 so that user to penetrate every time The when of hitting, being required for the position of the far and near Field adjustment graduation according to target, naked eyes judge target range simultaneously, Estimate that the point of impact that bullet is possible, regulation graduation and point of impact approximation overlap.And this scene according to target away from From and size, Field adjustment graduation and estimate that the mode of point of impact is limited to the experience of ejaculator itself completely, right If firearms are also very familiar with in the user having abundant shooting experience simultaneously, if ballistic trajectory is also well aware of, So use traditional optical foresight error can be smaller, and these experiences are required for substantial amounts of exercise and just can reach Arriving, aiming at when, also psychological quality own with ejaculator also has much relations simultaneously, generally speaking, uses There is great relation in traditional optical foresight and people.

Bigger defect is deposited, in recent years, along with digital technology, numeral for above-mentioned traditional optical foresight The technology fast developments such as image technique, material technology, signal transacting, some professional quarters propose and devise number Word sight (Digital Scope), its core concept be utilize digital technology, nnir Rtorae technologies and Image processing techniques substitutes traditional optical sight.The device of numeral sight is substantially camera and adds electronics Signal processor adds display screen to the multi-order optical enlarging lens substituting on optical foresight, the most on a processor Store adjustable graduation to the division device substituting on optical foresight.Owing to numeral sight is to use processor Accurately controlled graduation by image processing techniques, and the position of graduation is stored in non-loss beforehand through point of impact Property memory in, if therefore mentality of designing is accurate, substantially can correct all of traditional optical sight and lack Fall into.But due to the defect in mentality of designing or the mistake of design starting point own, cause the most existing number There is bigger problem in word sight, as follows:

1. graduation design existing defects

The graduation design of existing most numeral sights is to allow user go from Row sum-equal matrix or to preset multiple graduation Position, allows user select voluntarily, and the trajectory parameter of firearms cannot be reflected in the position of graduation itself, so The problem brought is not to be inherently eliminated the mistake that in traditional optical sight, graduation and point of impact approximation overlap Difference, and simply allow camera and display screen instead of the camera lens of optical foresight.In such design concept Under, in any case adjust the color of graduation, size, thickness etc. all cannot change the graduation position occurred on display screen Put the fact that there is error between actual bullet point of impact.

2. ballistic trajectory data unicity

Existing some numeral sights that have have been accomplished to allow graduation and point of impact overlap, the most in advance in graduation design Point of impact being stored in internal memory, point of impact is obtained by reality test, then the when of run-home, allows point Draw and jump to point of impact and allow user's aimed fire.The thinking of this design graduation is accurately, but these are digital Sight storing ballistic data when, only a kind of bullet impact information of storage, and point of impact quantity ratio Less (existing limit due to method of testing, ballistic error modification method, memory span etc., typically maximum Only about 20), it is impossible to the complete ballistic trajectory of this bullet of accurately sketching out, in closer distance Time, often shoot more accurate, but relatively remote, after 500 meters, owing to bullet is by weight Power acceleration affects, and the comparison of ballistic trajectory decline is severe, if the upward view angle of firearms in this time is incorrect, Firing error will be bigger, the most also cannot accomplish the mesh ground of precision fire.And store the unicity limit of data Made the track of same bullet different people shooting, different bullet uses on firearms, even shooting under varying environment Possibility.

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

Some existing numeral sights allow user to remove the Internet download bullet with oneself firearms coupling Ballistic data, stores on local storage, then calculates ballistic data error by additional computer, think By the way of theory calculates, revise the ballistic error at different distance with plug-in computer, then use this Revised ballistic data carrys out run-home as the graduation point of reference and uses.This idea starting point is the best , but the problem that presently, there are is: these bullet trajectory data are not the most through strict test and checking , in use, use these ballistic trajectory data as with reference to graduation, can exist and actual point of impact Bigger error.The mode of the most plug-in computer disposal, itself cannot accomplish to process in real time, when with After the lock onto target of family, it is desirable to shoot immediately, especially some translational speeds are than target faster, effectively hit Chance often moment just loses, and if by outer computer, sight is firstly the need of by current target conditions To computer, then after computer disposal by result to sight, so in the middle of lose the chance effectively hit. Therefore the different of firearms conventional on market are planted bullet, test under difficult environmental conditions simultaneously, obtain accurately , complete ballistic trajectory database those are not had a shooting experience, or the making of psychological quality less stable Just seem for user extremely important, if sight is by disposing high speed processor simultaneously, repaiied by algorithm Correction method real-time corrected trajectory parameter under various circumstances, the impact error of different distance point is also by direct shadow Ring the result of precision fire.

4. cannot accomplish the quickly tracking of target, automatically locking and precision fire

Existing all numeral sights are owing to depositing defect in design, and all cannot be truly realized target is fast Speed is followed the tracks of, is automatically locked and precision strike purpose, is not the most intelligent digital sight truly. And why intelligent digital sight will have huge market in future, main cause is to utilize high speed image signal Process and data process, and jumbo storage capacity, can be real accomplish to quickly the following the tracks of of target, Automatic range, automatic aiming, automatically lock, thus realize precision strike capability, similar self-navigation and radar Technology is the same at missile-borne guidance technology.Sight is so made to be no longer rely on human factor, though a milli The people of nothing shooting experience is using intelligent digital sight when, as long as operating according to the rules, it is possible to realize Precision fire purpose.And existing digital sight is due to the many disadvantages in design, this point also cannot be accomplished. The present invention proposes a kind of novel digital sight apparatus, and the network topology core texture of this device is main By: numeral sight, the APP of mobile terminal, Cloud Server and four big key elements of social networks form, from And construct one based on intelligent mobile interconnection technique, towards " outdoor shooting and the Internet of Things of hunting “(OSHN).Numeral sight, should mainly by: high definition the camera that possesses automatic or manual zoom capabilities Camera be also equipped with simultaneously stronger speed perception compared with the target under decreased light environment, high speed polycaryon processor at Manage realtime graphic and other data, the high-definition display screen, in high precision touch-screen of camera, there is energy of finding range farther out Power also possesses the laser range sensor of degree of precision, wireless communication module, global location GPS module, great Rong The non-loss memory of amount, all kinds of can the composition such as sensor of real-time testing environment.The APP of mobile terminal Major deployments application program on intelligent movable mobile phone or mobile IPAD (panel computer), its function master If realizing data in the wild to forward and interim memory action.The effect of Cloud Server realizes the standby of data exactly Part, the renewal etc. of program act on.The core concept of the present invention is to allow user utilize numeral sight to realize shooting The quickly tracking of target, automatically locking and precision fire, its basic ideas are: clap in real time with high-definition camera Take the photograph potential target, by laser range sensor real-time testing target range, with gravity acceleration sensor, gyroscope Determined the translational speed of target Deng sensor by " three limit positioning modes ", record current wind with air velocity transducer The data such as speed and wind direction, these data are stored in internal memory in real time.User passes through display screen object observing, is penetrating Need before hitting target test storage in advance or download the trajectory of the conventional bullet that such firearms mate from server Track data, stores in memory with database form.When user determines that high-definition camera has traced into mesh Mark, and after laser range sensor the most accurately measures target range, just start LOCK locking, processor According to target range and recall coupling these distance ballistic trajectory data, simultaneously each sensing data of Real-time Collection, Particularly " wind wafts " data, by " trajectory parameter error is revised in real time and compensates " algorithm correction different distance Impact error, revised point of impact presents on a display screen with the form of graduation.Simultaneous processor can be located Reason captured in real-time view data, allows graduation show at screen center by image procossing mode, simultaneous processor Can automatically drive the optical lens of camera so that target is the most gem-pure to be presented.Use Person opens fire target, owing to graduation is some display centered by the point of impact of revised actual bullet, therefore Bullet must accurately hit the target area that graduation shows.Owing in this process, substantially need not manually join Have only to target to be hit for the camera alignment of numeral sight with, user, follow-up all with Numeral gun sight self run-home, calculating target range, automatic focusing, automatic lock onto target, and hit Point also can be very accurate, be thus truly realized quick trackings to target, automatic aiming, automatic lock and The idea of precision strike.
