In foregoing, two generating lasers substantially work in all the period of time, although passing through in a preferred approach
The control generating laser working time daily schedule of light sensor or birds is set, but actually
Or meeting work really long days, the service life of generating laser is reduced, and scarer is typically set partially
Remote area, safeguard very convenient.Therefore the working time of further reduction scarer is needed.In addition, though
Laser will not damage to the vision of birds and other physiological activities, but more or less can also produce
Some raw light pollution.
In order to solve this problem, the generating laser working time is controlled, the present embodiment is using following preferred side
Case.
The generating laser front end is also equipped with camera assembly, and the camera assembly is connected to the control panel
Single-chip microcomputer, the single-chip microcomputer controls the direction of illumination of two generating lasers, i.e., also controls shooting simultaneously
The direction of taking pictures of component.Specific control method is as follows：
Step S11, the timed interval of single-chip microcomputer timer is set, and if setting generating laser
Dry luffing angle position alpha and several level angle positions β, wherein 0 °≤α≤180 °, 0 °≤
β≤360°。
Scarer continuously works without the moment, when setting the work of scarer according to the daily schedule of birds
Between, then interior setting runs at work, carry out a 3-D scanning, sentence at regular intervals
Whether disconnected periphery has birds, restarts generating laser if having, otherwise keeps holding state, can be very
The working time of good control generating laser, increase the service life.
When camera assembly often carries out once photo taking, the photo of one fixed width scope and altitude range can be photographed,
For example the width subtended angle of photograph is 90 degree, height subtended angle is 45 degree, can so set Laser emission
The 5 luffing angle positions and 4 level angle positions of device, 5 luffing angle position distributions are 0 degree,
45 degree, 90 degree, 135 degree, 180 degree, luffing angle be 0 degree when, generating laser just upward, pitching
When angle is 180 degree, generating laser is just down.4 level angles are 0 degree, 90 degree, 180 degree,
270 degree.
Step S12, when receiving scanning recognition instruction, two generating lasers of control are in the same direction, then control
The luffing angle of two generating lasers of system is from first luffing angle position gradually to last luffing angle
Change in location.
Step S13, during pitch rotation, for each luffing angle position, Laser emission is controlled
Device gradually goes to last level angle position from first level angle position, realizes 3-D scanning, and
At each level angle position, taken pictures before and after two camera assemblies of control, obtain two photos and transmit
To single-chip microcomputer, the photo opporunity difference of two photos is △ t.
When timer triggers every time, single-chip microcomputer receives scanning recognition instruction, controls two Laser emissions first
Device is in the same direction, then controls generating laser to be located at first luffing angle position, and gradually bowed to last
Face upward change in angular position.At each luffing angle position, generating laser is controlled from first horizontal angle
Degree position gradually goes to last level angle position, i.e., is rotated by 360 ° in each luffing angle position,
Realize 3-D scanning.And in each scan position (i.e. each luffing angle position, each level angle
Position) camera assembly obtains photo and is sent to single-chip microcomputer.For two kinds of 0 degree, 180 degree special pitching
Angle position, can also be without being taken pictures in each level angle position, the photo of gained because it is taken pictures
All it is identical.In the present embodiment, under each scan position, two camera assemblies are successively taken pictures, when having
Between it is poor, the time difference is traditionally arranged to be the 0.5-1 seconds.
Step S14, during 3-D scanning, the single-chip microcomputer is carried out according to two photos received every time
Identification judges no there is bird；
Step S15, when finding to have bird, two laser transmitter projects laser are controlled, and in the photo
The laser beam of two laser transmitter projects is controlled to strafe in the range of taking pictures；
Step S16, when not finding bird after completing a wheel 3-D scanning, scarer is in standby shape
State is until receive next scanning recognition instruction.
Single-chip microcomputer identifies whether there is bird by pre-defined algorithm from two photos successively obtained, when discovery has bird
When, two laser transmitter projects laser are controlled, two beam laser are strafed in the range of taking pictures, real
Existing bird repellent purpose.Sweep times can voluntarily be set, generally 5 minutes.If after a wheel 3-D scanning,
Bird is still found no, then generating laser continues standby, and single-chip microcomputer waits next scanning recognition instruction.
As a kind of recognizer, above-mentioned steps S14 is specifically included：
Step S21, the intersection of two photos is taken out；
Step S22, gray proces are carried out to two photos, then ask intersection gray scale difference value it is absolute
Value, obtains error image；
Step S23, binary conversion treatment is carried out to the error image, obtains intermediate image；
If there remains black patch region in step S24, described intermediate image, judge there is bird in photo.
Although two camera assemblies are in the same direction, certain distance, therefore two photographs that shooting obtains still be present
There is certain deviation in piece, the deviant is definite value, is compared then in conjunction with photo in the horizontal direction, it is easy to
Obtain the intersection of two photos.Then gray proces are carried out to two photos, then seeks intersection
The absolute value of gray scale difference value, error image is obtained, finally obtains intermediate image by binary conversion treatment.
Generally, bird is all active state, for example bird is just in state of flight, or station is in power tower
Or wing is shaken on electric wire, swings head etc., few birds are not moved at all, therefore to two photos
Gray proces, ask poor, then binaryzation obtains intermediate image, if bird is flying, intermediate image will necessarily obtain
To two black patch regions, if bird is shaking wing on power tower or electric wire, swinging head etc., also can
Black patch region is seen with a position, thus whether black patch region is had substantially according to intermediate image it is determined that
Whether bird is had.
But if there is no black patch region in intermediate image, no bird can not be directly judged, because really can
That bird plants oneself be present, it is therefore desirable to determine whether there is bird in photo.This algorithm also includes
Following step：
If not having black patch region in step S25, described intermediate image, wherein one is selected by gray scale
Photo after reason, referred to as gray scale pictures；
Step S26, according to pixel gray value size in the gray scale pictures, saltus step occurs in gray value
Pixel is boundary pixel point, obtains the boundary profile of the gray scale pictures；
Step S27, the straight-line segment in the boundary profile is taken；
If one section of raised irregular contour between step S28, similar two straight-line segments be present, sentence
Determine have bird in photo.
This scarer is arranged on electric power tower, and electric power tower is made up of angle steel, channel-section steel, Er Qie electricity
Power steel tower height is very high and is located at outer suburbs, therefore steel tower surrounding scenes are less, the difference even if birds are stood.
It typically also can only stand on angle steel, channel-section steel or electric wire, be not in other positions.Therefore in preferred scheme,
It is that can obtain the side of object in photo according to the saltus step situation of gray value after gray proces by photo array
Boundary's profile, all it is straight line in general profile, if there is bird on one's feet, then will necessarily go out on straight line
An existing raised irregular contour is raised irregular in the presence of one section between that is, similar two straight-line segments
Profile, so substantially it can be assumed that being bird corresponding to the irregular contour.So-called irregular contour, the i.e. wheel
Wide shape is indefinite, is not rectangle, circle, ellipse, triangle, trapezoidal etc., is a kind of indefinite shape
Profile.
This recognition methods can only be useful in this specific occasion, be identified for birds in common scenarios, use
This mode can not be realized.Although this recognition methods is simple, very useful.
If it is necessary, can also further confirm that the irregular contour is bird, concrete scheme is as follows,
That is above-mentioned steps S28 is specifically included：
S31, the irregular contour gradient change point jumpy is recorded, and according to the change point to institute
State irregular contour to be segmented, obtain multistage rim path；
S32, a M graded data among every section of rim path are recorded, obtain route characteristic vector,
Wherein described graded data are the gradient difference value of two neighboring point；
S33, route characteristic vector is compared with the feature database locally preserved, when with wherein one outside
When shape characteristic similarity is more than 50%, current irregular contour is judged for bird, i.e., has bird, institute in photo
State similarity is specially more than 50%：Resemblance data in gradient difference value and feature database in characteristic vector
Compare.Then recognize within the specific limits for each gradient difference value and the respective items purpose difference of resemblance data
Surely it is set of metadata of similar data, otherwise regards as different pieces of information, when characteristic vector and a resemblance data are completeer
Afterwards, set of metadata of similar data is more than the number of different pieces of information, then assert that similarity is more than 50%.
The appearance profile of birds has certain feature, nor arbitrary shape, there is rule can follow.First
Need to set up feature database, preserve a plurality of resemblance data, every resemblance data are by multiple ladders
Spend difference data composition.
Specifically, in the present embodiment, the irregular contour gradient change point jumpy is recorded first,
These change points are exactly the turning point of profile, are exactly one section of wing path between two neighboring change point, so
Multistage rim path is obtained, for each rim path, decile sets M point, calculates each point gradient number
According to, i.e. gradient, then calculate this M graded data, i.e., the gradient difference value of two neighboring point, most
Obtain eventually current irregular contour route characteristic vector, then by route characteristic vector with feature database in each bar
Resemblance data are compared, and when similarity is more than 50%, judge current irregular contour for bird, i.e.,
There is bird in photo.
So compare by multi-level, substantially can reach timely bird repellent whether to have bird in accurate judgement figure
Effect.Certainly some extreme None- identifieds can also be present, for example, bird position just by channel-section steel
Block, these extreme cases do not interfere with the effect on driving birds of the present apparatus substantially yet.Present embodiment timing is examined
Whether survey has bird, just carries out laser fire when only having detected bird, reduces the work of generating laser
Make the time, extend its service life, avoid frequent device from safeguarding.
This scarer has wireless communication module, and remote monitoring can be achieved.Routine can be arranged as required to
Working method, i.e. generating laser continuously works.It can also be set according to above-mentioned control program.
This scarer fully combines laser and sound bird driving scheme, considers to birds regarding as vision animal
Feel susceptibility, when using laser bird expelling, during bird repellent purpose is reached, more to ensure that laser will not be right
The vision of birds and other physiological activities damage, and ensure harmony between man and nature development.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in this hair
All any modification, equivalent and improvement made within bright spirit and principle etc., should be included in the present invention
Protection domain within.
