Description
Technical field
The invention belongs to technical field of laser detection is and in particular to a kind of wireless automatic target-indicating laser school rifle instrument.
Background technology
Due to cumulative errors in gun structure design, processing and manufacturing and assembling process, the such as impact of gun barrel straightness error,
School rifle must be shot at before dispatching from the factory, the concrete grammar of school rifle is by adjusting pointing device height with direction it is ensured that playing
Point all can hit in the inspection circular scope of regulation.Traditional school rifle method is in special fixing stand by body of a gun clamping
On, naked eyes aiming is passed through by sharpshooter and is shot at, judge to adjust according to the alternate position spike that actual point of impact and shooter aim at
The height of pointing device and direction.This method is due to being affected it is impossible to truly reflect by inevitable personal error
The fire accuracy of gun, the fire accuracy thus resulting in gun is unstable, and qualification rate is low, and workload of returning to school is big, and consumption bullet is many.
For this reason, Harbin laser institute laser school rifle develops group and Chengdu temperature Watch Factory thunder book spring etc. existing respectively《Swash
The research of light school rifle》(weapons laser 1981 (2)：16-18)、《Laser school rifle, TV indication of shots technology》(application laser 1986,6
(5)：Propose in 228-229) by the use of helium neon laser as light source, gun barrel install reflecting mirror make the laser that reflects away with
Gun tube axis overlap, and form bright hot spot, so bullet can be replaced target position with laser facula on target, and pass through position
In the video camera of target position, observed by industrial television so as to aim at the bull's-eye, then constantly adjust firearms foresight, so that it is pointed to
Target center is thus reach the purpose of school rifle.But this article methods described is mainly by procurator's subjective judgment facula position, do not provide
One objective basis.In addition laser instrument volume, can only be by being arranged on the reflecting mirror at gun barrel, constantly greatly it is impossible to insert gun barrel
Adjustment, makes the light of reflection overlap with gun tube axis.So not only equipment is complicated, adjustment is wasted time and energy, and be subject to video camera and
The display resolution of industrial television and the impact of precision, school rifle precision is extremely limited.
In recent years, also Chinese patent (patent No. CN200820062262.0) disclosed pluggable gun barrel and accurately determined
The laser beam emitting device of position, it is ensured that the laser beam projecting is overlapped with gun barrel centrage, replaces bullet target by laser facula, adjusts
Whole foresight, realizes no bullet school rifle.Also has the motion rail that Chinese patent (patent No. CN201010118545.4) flies according to bullet
Mark calculates the alternate position spike of actual point of impact and laser facula in the case of range determines, by adjusting aiming point and actual point of impact
It coincide and reach the purpose of school rifle.But target position is apart from shooter farther out (30～100m), after laser target, formation spot diameter is larger,
Just can must be seen by telescopic system, both leans on the method precision of testing staff's subjective judgment spot center position very again
Limited, and the objective basis also without school rifle.
In gunnery training application, there is Chinese patent (patent No. CN200920174969.5) to propose and be equipped with laser
The gun of emitter, wireless hit teller and laser target device are simulated training.Concrete grammar is that generating laser is pressed into rifle
Tool magazine, projects the laser beam overlapping with gun tube axis to laser target device, equipped with multilamellar laser pick-off ring on laser target device,
Detectable hot spot present position number of rings, is sent to wireless hit teller by wireless module simultaneously.This patent formula can only be reported roughly
Go out the number of rings of laser facula present position, concrete orientation cannot obtain, it is impossible to provide foundation for school rifle, detecting people in a ring
Member does not know that this aims at utensil to the adjustment of which direction, and each ring width is also very big, precision not high it is impossible to be used for gun school
Accurate.
Additionally, have Chinese patent (patent No. CN200420115331.0) to propose using the laser being loaded on gun again
Device, target surface, the video camera of collection target surface image, graphics processing unit and computer composition simulated training system.Laser instrument is direct
Collection target surface image information simultaneously calculates facula position data, is analyzed and shown by graphics processing unit and computer.Should
Method can quote facula position automatically, but it separately has disadvantages that it is difficult to be applied in firearms calibration.First, camera
Installation requirement is extremely complex, needs to be arranged near target position and reliability is fixing, subsequently carry out system calibrating, in use,
The variation of camera position easily causes system data errors and must re-scale.Secondly, this patent can be only applied to completely
Indoor range complex, target and video camera are exposed to outdoor, are easily subject to the erosion damage such as rainwater, and by sunlight interference, target surface is reflective, take the photograph
Camera lens such as are stained at the impact, and image processing software is difficult to differentiate facula position.Again, in this patent methods described, video camera
Can not possibly align with target surface, can only be observed from side, otherwise stop that laser target, however, video camera forms one with target surface
After determining angle, bring analytical error, cause indication of shots precision not high.This patent is also less prone to realize miniaturization, and mechanism is complicated, needs to join
The standby equipment such as video camera, image processor, computer, maintenance cost is very high.
In recent years, many mechanisms have carried out the research of the alignment sensor of recognizable laser facula two-dimensional coordinate.Nanjing is managed
The emerging grade of work university Wang Zhi exists《New Two Dimensional laser positioning imageing sensor》(the electronic product world 2002 (7)：68-70) in a literary composition
Propose the two-dimentional cmos image sensor of application and do receiving device, receive target surface with hot spot and be made of one, entered using dsp processor
Row image procossing, can be with automatic detection laser facula two-dimensional position coordinate.This article proposes small-range, two kinds of sensors of wide range
Scheme, and illustrate application in multiple environment such as track and localization, position detection for this sensor.But this article closes to many
Key technology problem does not refer to, simply proposes a kind of conception, and according to this article conception, range to be made is the biography of 500 × 500mm
Sensor, thickness direction 800mm at least to be accomplished, volume is excessively huge.This article does not propose its application on the rifle of laser school yet.
Also have document to propose and facula position detection is carried out using two-dimension displacement sensor PSD, but all do not mention on the rifle of laser school
Application.
