Abstract

The radar video signal entirety periodic refreshing textures display methods based on GPU that the present invention relates to a kind of, including：The display of a kind of radar primary video data display processing isolation technics based on GPU, radar refreshes, and data manipulation and sunset glow processing separation are not interfere with each other.The whole radar primary video display effect for refreshing primary video method for displaying image, ensureing under High Data Rate of timing simultaneously.

Description

Radar video signal entirety periodic refreshing textures display methods based on GPU
Technical field
The present invention relates to a kind of radar video signal display methods.
Background technology
At present in the technical research and equipment preparation of phased-array radar primary video data processing field, the thunder of software implementation Show that the main method painted in real time a little is shown up to primary video, and phased-array radar high bandwidth, High Data Rate development trend It is influenced greatly by data transfer rate in the presence of display rate effect so that the primary video of currently used software implementation paints a method for display, Refresh rate is low and unstable, the drawbacks such as data filling and sunset glow processing difficulty.
Document《A kind of radar terminal software implementation display methods》(Miao Zhenkui,《Modern defense technology》2 monthly magazines in 2014) and Document《Radar video image real-time display technology based on Direct3D》(Wang Lingling, Wang Jian, Wang Xiangmin,《Radar and confrontation》 2 monthly magazines in 2009) it is each provided with a kind of more universal software implementation radar primary video Display Realization method, but two documents The method for using radar data point-by-point mapping, and screen point is redrawn with sunset glow effect by complicated algorithm.Such side Method does not detach data manipulation with display function, and the rate of display is influenced greatly by data transfer rate, and refresh rate is unstable, sunset glow effect It realizes difficulty, and cannot achieve multichannel data while drawing.
The problem of being influenced by data transfer rate the present invention overcomes radar refresh rate, the refresh rate of radar data is stabilized, Data filling and sunset glow processing method are simplified, a large amount of data can be filled simultaneously as desired or is carried out at mass data The rate managed without influencing display, and can be realized simultaneously multichannel data while handling and showing.
Invention content
It is shown the purpose of the present invention is to provide a kind of radar video signal based on GPU and method for refreshing.
Realize that the technical solution of the object of the invention is：By loose coupling thought, display is detached with data manipulation, The space of matrices of one specific format is set in system, each index represents a coordinate points during video is shown in matrix, Corresponding data need to be only converted to RGBA by the RGBA values that the lower content of index represents displaing coordinate point when radar data is filled In the corresponding index of respective value filling, when sunset glow is handled, it is only necessary to do subtraction operation to matrix specific data, no longer need to execute Display operation.A timer is arranged in system, and the data in space of matrices are periodically sent into GPU in the form of textures and carry out whole paint System refreshes on the screen.
Description of the drawings
Fig. 1 present system structure charts.
Specific implementation mode
The space of matrices a [x] [y] [3] of one specific format is set in systems, and the x in matrix a represents radar video In x coordinate, y represents y-coordinate, and [3] respectively represent the RGBA values of this point display, and what ranging from 0-255, A were represented is transparency, Initial value should be set as 150, when radar data comes in fill by outside transmission, according to orientation azi and distance Distance, calculates the corresponding xy axial coordinates point in screen, and the xy coordinate points such as calculated carry decimal, then carry out rounding behaviour Make, and corresponding data need to be only converted in the corresponding index of RGBA respective values filling according to amplitude calculating, does not execute display Refresh operation.
When sunset glow is handled, according to specific time interval t, the rgba for the corresponding space of matrices a that sequentially decays as required The size of value, value indicates sunset glow intensity size, i.e., according to being starting point with matrix x=0, y=0, x=x, y=y are terminal, cycle The value of each data point is subtracted into s, and the interval time t to decay next time is set after primary decaying, between decaying The power of sunset glow can be codetermined every time t and s, display refresh operation is not executed in this operation.
System be arranged a timer, periodically with 30 frames or 60 frames frame per second per second by the data in space of matrices to paste Diagram form is sent into GPU and carries out whole drafting, refreshes on the screen.Refresh operation with independent thread carry out, with data filling and Sunset glow processing is not mutual exclusion, to ensure the frame per second refreshed.
Data are filled in the method, and sunset glow processing, the display of system is completely independent, and is mutually not provided with mutual exclusion condition.Data The inside of filling or sunset glow operation can be carried out in the form of multiple threads parallel simultaneously.If data are filled, sunset glow operation When being carried out parallel in the form of multiple threads etc., it is multiple carry out parallel data filling or sunset glow operation between do not set mutual exclusion item yet Part and be completely independent.That is the filling of each parallel data or sunset glow operation is completely self-contained.But in order to ensure display effect Fruit is also independent and is not mutual exclusion, display operation although data display operation is filled with data between the operation of person's sunset glow Inside can only there are and unique operation, cannot carry out parallel.

Claims (1)

1. a kind of radar video signal entirety periodic refreshing textures display methods based on GPU, it is characterised in that:Radar video It has been shown that, data stuffing operations, sunset glow processing realize thorough independence：There are the squares of a radar video data in Installed System Memory Battle array space, the filling of radar video data and the processing of sunset glow effect are simple this space of matrices of data processing operation, It is not related to system to show；By space content, the incoming GPU of the timing in a manner of whole textures is shown system with periodic refreshing radar video； Radar data padding and internal multichannel filling and the sunset glow of being carried out at the same time in a parallel fashion of sunset glow processing are handled, and simultaneously Capable operation is completely independent；The display of video then can only be handled individually all the way, it is not possible to parallel processing.
