Abstract
The invention relates to a method for showing a radar initial video of in real time, comprising the following steps: the triggering data of the radar initial video data is organized to form a data structure; the radar initial video on the triggering data is sampled, compressed and organized into the data structure; the organized data structure is received by a computer after being stored or transmitted; the data structure is decompressed according to triggering, and scan conversion is carried out on the data structure on the same triggering according to the azimuth and the distance; and the data structure finally obtained is multiple points formed by the coordinate positions and amplitudes on a screen, and the data structure is rendered to the screen to realize real-time showing of the video according to the rotating speed of a radar antenna after being stored into the video memory of the computer.
Description
Technical field
The present invention relates to the method that a kind of radar video represents, particularly a kind of method that can represent in real time the radar original video.
Background technology
The radar original video is a main foundation of obtaining aerial, ground and waterborne target information in real time.The real time radar video display (comprises as radar P display mode, B display mode, A/R display mode, wherein the P display mode is radar bearing/distance display mode, the polar coordinates that are common sense show that the B display mode is distance by radar/distance display mode, and promptly the rectangular coordinate of common sense shows.The A/R display mode is radar amplitude/distance display mode) can provide intuitive and accurate visual determination to the radar controller.
Mainly be to represent at present by representing in real time of realizing of special hardware circuit with based on the non real-time of common computer for the radar original video.
Under multi-purpose computer, adopt conventional treatment method to realize that the real-time demonstration of radar original video is very difficult, illustrate: the radar raw video signal is by the software scans conversion, the radar original video is corresponding with screen pixel coordinates position, provide the radar original video information by the color that pixel is set to the user then.Suppose that the radar original video picture size that will show is 1000 * 1000 pixels, the rotating speed of radar antenna is 30 rev/mins, approximately to draw 500000 picture elements so p.s., and 500000 picture element colors (multi-purpose computer of mainstream configuration directly is set by the GUI mode, double-core 2.0GHz, the 4GB internal memory), need about 6.2s approximately, therefore, if when showing the radar original video continuously, this mode requires very high to CPU, when radar antenna rotating ratio faster the time, because the computing machine response is untimely, display delayed or loss of data phenomenon will inevitably occur.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
At above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of method that can represent in real time the radar original video.
For achieving the above object, the method that represents in real time of radar original video of the present invention can adopt following technical scheme:
The method that a kind of radar original video represents in real time, this method may further comprise the steps:
(1) the trigger data tissue of radar original video data is formed data structure, the compression and organizing to data structure of then the structural radar original video of this trigger data being sampled;
(2) with after the storage of data structure process or transmission of organizing in the step (1), receive by computing machine;
(3) to the data structure according to triggering decompress(ion), the data structure in the same triggering is carried out scan conversion by azimuth-range;
(4) data structure that finally obtains is the many points that are made of coordinate position on screen and amplitude, deposit the video memory of computing machine in after, according to the rotating speed of radar antenna, this data structure is played up to screen.
The method that radar original video of the present invention represents in real time is implemented on the computer platform, network real-time receiving radar original video data, play up representing in real time by data structure to screen realization video, and the P that can realize the radar original video shows, B shows, A/R shows and comprehensively represents, and can on a computing machine, represent the original video information of multi-section radar simultaneously, stack shows.
Embodiment
Below in conjunction with embodiment, further illustrate the present invention, should understand following embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
The present invention discloses the method that a kind of radar original video represents in real time, and this method may further comprise the steps:
(1) the trigger data tissue of radar original video data is formed data structure, the compression and organizing to data structure of then the structural radar original video of this trigger data being sampled;
(2) with after the storage of data structure process or transmission of organizing in the step (1), receive by computing machine;
(3) to the data structure according to triggering decompress(ion), the data structure in the same triggering is carried out scan conversion by azimuth-range;
(4) data structure that finally obtains is the many points that are made of coordinate position on screen and amplitude, after depositing the video memory of computing machine in, rotating speed according to radar antenna, this data structure is played up to screen, in this step, can use DirectX technology or OpenGL to play up technology and the data structure is played up be handled to screen.Wherein the DirectX technology is a kind of development mode of directly operating in the face of computer display card that Microsoft provides, and comprises System Framework and kit; And OpenGL plays up the 3D routine interface that technology is a specialty, be one powerful, call bottom 3D shape library easily; These two kinds of graph rendering methods are the computer realm technology of playing up commonly used.
Also comprise in the described step (4) and carry out hand-off process playing up to the data structure of screen, this hand-off process is this to be played up to the data structure of screen be divided into foreground show layers and background process figure layer, the figure layer that the foreground show layers shows at graphoscope after for the video memory of directly inserting computing machine, background process figure layer is the mapping graph layer corresponding with the foreground show layers, two figure layers carry out one after the other, realize the processing of brush screen.
The method that radar original video of the present invention represents in real time is implemented on the computer platform, network real-time receiving radar original video data, play up representing in real time by data structure to screen realization video, and the P that can realize the radar original video shows, B shows, A/R shows and comprehensively represents, and can on a computing machine, represent the original video information of multi-section radar simultaneously, stack shows.And present technique makes full use of the visual development instrument of business software (DirectX, OpenGL) based on computer platform, and exploitation, debugging method is convenient, is easy to function transplanting, expansion.Once more, present technique can be preferably combines radar original video and secondary data information (as the flight path information of window information, radar tracking, label information, primitive information etc.), can derive many new display modes, show the 3-D display of the stepless amplification of window/dwindle, target echo etc. as P.
