Brief description of the drawings
Fig. 1 is flow chart of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is the part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of protection of the invention.
As shown in figure 1, specific implementation process of the present invention：
101st, Real time data acquisition and coordinate transform process.By way of network or serial communication, radar is obtained in real time
The raw position data that equipment returns, the radar point coordinates of return are represented, it is necessary to which polar coordinates are converted into using polar coordinates (r, θ)
With Descartes's that coordinate (x, y).Support multiple radar equipments while handle, same as below, each radar processing procedure is placed on
Carried out in one thread, so as to ensure the real-time of whole system.
102nd, radar fix and projection coordinate's calibration process.The process is to determine several mark points in advance, records the mark
Radar fix and picture displaing coordinate corresponding to note point, because mark point is respectively, so the picture displaing coordinate of mark point
It is known, it is necessary to express its corresponding radar fix.Whole projected picture is divided into H*V son first and shows picture
Face, the corresponding sub-viewing areas of a radar, every sub- display picture have M*N mark point, and M*N mark point is uniformly distributed
In sub- display picture.Whole calibration process is demarcated one by one by radar, and barrier is successively placed on corresponding to the radar
In the mark point of sub- display picture, the radar fix of the mark point is recorded successively by calibrating procedure, until all radars are corresponding
Mark point all complete to demarcate.
103rd, radar available point screening process.The coordinate points that radar returns only just are having corresponding to it in sub- view field
Effect, invalid point needs filter out, so as to reduce the complexity of calculating.Single radar is corresponded into sub- projected picture by mark point
Number carries out triangular grid, is divided into * 2 triangles of (M-1) * (N-1), has demarcated radar fix and projected picture coordinate
Afterwards, radar fix Rp and screen coordinate Sp corresponding to each apex of triangle is to determine.Traversal radar points are judged
Whether it is in arbitrary triangle, and the point in triangle is effective radar points, otherwise is invalid radar points.Judge one
Whether the method in triangle ABC is to first determine whether that P and C whether in AB sides, then judges P and B whether in AC mono- to point P
Side, then judge that P and A whether in BC sides, only these three conditions meet simultaneously when, can be concluded that P inside triangle ABC.
104th, radar point coordinates mapping viewing area coordinate process.Step 3 determined in which triangle residing for radar points,
The radar fix and screen coordinate of the Atria vertex correspondence are known again.The problem is converted at known one o'clock one
Coordinate in individual triangle, solve its coordinate in another triangle.Any point P is represented by P in triangle ABC
=K1*A+K2*B+K3*C, and K1+K2+K3=1, wherein K1=Square_BCP/Square_ABC, K2=Square_ACP/
Square_ABC,
K3=Square_ABP/Square_ABC, arbitrfary point P in triangle T 1 can be tried to achieve by relation above and be mapped to triangle
Coordinate points in shape T2 are P'=K1*A'+K2*B'+K3*C'.Screen corresponding to effective radar points can be solved by the method
Coordinate.
105th, radar points process of cluster analysis.Because radar points are than comparatively dense, live animal may be felt after entering induction zone
Multiple radar points are answered, the live animal closed on can also sense multiple radar points, and it is crucial for how effectively distinguishing different live animals.Root
Process according to the distributional analysis mobiles of radar points is exactly cluster analysis, and the higher radar points of aggregation extent are considered into one
Individual effective coverage, the coordinate after the radar points mapping in the effective coverage is then subjected to equalization and sat as an effectively triggering
Mark.Process of cluster analysis：All effective radar points are traveled through first, calculate neighbor point number in radar points radius r, point of proximity
In addition dynamic array Array of the number more than n, less than casting out for n.Then by all effectively radar points in Array by neighbouring
Point number is ranked up from big to small, then the array after descending is traveled through, and is first inserted first effective radar points dynamic
In state array Array1, then already present effectively radar in the effective radar points being inserted into Array and Array1 is clicked through
Row compares, and with the effective radar points coordinate distance being inserted into is less than r1 if existed in Array1, and that gives up that this is inserted into has
Radar points are imitated, radar points that are on the contrary then being inserted into this are inserted in Array1.After being disposed, effective radar points in Array1
It is final contact cluster member, the adjacent point of the point is then subjected to the final coordinate that equalization is the contact.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, various equivalent modifications can be readily occurred in or replaced
Change, these modifications or substitutions should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be with right
It is required that protection domain be defined.
