Description
Technical field
The present invention relates to areas of information technology, be specifically related to a kind of coding structure, also relate to based on.
Background technology
In recent years, along with China's sustained economic development, increasing rapidly of vehicles number, the harbour container traffic growth is swift and violent, aviation identification is also more and more higher to the accuracy requirement that target positions, and increasing to the difficulty of the object identifications such as license plate number, container number, landmark-type building, when identifying, aviation has following technological difficulties:
One, the object identification of China such as car plate licence plate, container number etc. exist the problems such as number plate suspension is lack of standardization, pollution, partial occlusion, the sign of vehicle production producer, body advertisement, individual character car owner scribble on car body etc. all causes interference to image recognition in addition, all may affect the process to collection number plate Image Information Processing;
Two, the impacts such as the motion of object and light gather the quality of images: when being identified object and being kept in motion, the image information of collection can produce distortion; The in addition strong jamming such as headlight for vehicles, sunshine light source direct projection, reflection also can impact the image acquisition of object identify label;
When three, aviation identification positioned buildings, the buildings top lacked corresponding identify label as the target of image information collecting, caused the title that aviation identification can not clear and definite buildings, so that can't realize the precise positioning to buildings.
For above-mentioned several technological difficulties, adopt at present the mode that strengthens the camera precision to solve, very high but the expense of the method drops into, can only could realize in flourishing area.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of two primary colours grid groups and based on the identification method of two primary colours grid groups, can solve the existing identification of taking photo by plane needs enhancing camera precision to improve bearing accuracy, expense drops into high, the problem that can only realize in flourishing place.
The present invention is achieved through the following technical solutions:
Two primary colours grid groups, comprise the capable n row of the m grid group that the grid by dark, shallow two kinds of primary colours combines, described grid comprises two primary colours label layer, described two primary colours label layer are divided into dark primary colours label layer and shallow foundation look label layer, described dark primary colours label layer is cellular by the prismatic end of a plurality of hollows and combines, and described shallow foundation look label layer is cellular by the bottom surface of the bottomless pyramid of a plurality of inverted hollows and combines.
The further improvement of the present invention scheme is, grid is spatial structure, and described two primary colours label layer are located on the sign collet layer, and described two primary colours label layer upper surfaces are provided with transparent surface layer.
A kind of identification method based on two primary colours grid groups comprises the identity name that is identified object, and described identity name is comprised of p the character of arranging by rule, may further comprise the steps:
(1) P character encoded successively, described coding is the sign that is made of two primary colours grid groups;
(2) the two primary colours grid group of the P after will encoding are divided into q son and identify;
(3) increase origin identification in the first two primary colours grid groups, one side, define thus the recognition sequence of antithetical phrase identifier;
(4) recognition sequence according to step (3) definition is arranged on q son sign on the object.
The further improvement of the present invention scheme is, the quantity q of son sign is integer, and its size is: 1≤q≤p.
The further improvement of the present invention scheme is that origin identification is combined side by side by dark, the shallow two kinds of primary colours grid groups that are respectively capable 1 row of m.
The further improvement of the present invention scheme is that recognition sequence is: take origin identification as starting point, and from left to right clockwise direction or from top to bottom direction.
A kind of identification method based on two primary colours grid groups of the present invention, step (1) and step (2) can be changed P character code and the order of cutting apart, that is: be q part with P Character segmentation first, then q part are encoded successively.
The present invention's advantage compared with prior art is:
One, the hollow prism structure of dark primary colours label layer so that incident ray absorbed to greatest extent, the structural design of the bottomless pyramid of inversion hollow of shallow foundation look label layer makes from the light of all directions incident and effectively reflects away, thereby contrast and the resolution of Effective Raise sign create favorable conditions for the image information collecting of taking photo by plane;
Two, the character with the identity name of object carries out binaryzation, the useful area that the gained binary image can be identified increases, compare identification with the regular good character in the input character recognition system, accuracy is higher, realizes simpler in computer recognition system;
Three, reduction is to the accuracy requirement of camera, and expense drops into low, is fit to each department and uses.
