By the invention, the recording of image and data can reach result of the alignment of data, no losing frame and no string frame.
Description
Technical field
The invention belongs to the digital image processing techniques field, relate to the storing apparatus of image, specifically a kind of digital-image non-loss recorder.
Background technology
Digital-image non-loss recorder is mainly used in scientific experimentation and optical measurement, and non-loss recording high speed image data and measurement data information are so that carry out the accurate quantification analysis to high-speed moving object afterwards.Carry out the digital-image non-loss recorder technology abroad and want Zao than domestic, at the end of the nineties, Hesperian well-known image product company such as the Canada and the U.S. has succeeded in developing this series products, and puts on market.But the shaped article of import can not satisfy the specific demand in the practical application fully, such as, the synchronous recording data and the data of carrying out are synthetic etc.
Domestic digital-image non-loss recorder report appears at 1998, the institute of Beijing commander control at that time is according to the problem needs, develop IMAQ storage card based on the ASI bus, this card is mainly by image capture module 1, acquisition and recording control module 2, Imagery Data Recording module 4 constitutes, can only finish acquisition of image data and be stored in the Imagery Data Recording module 4, and can not satisfy the real-time synchronous recording of user, and support less for the function of browse of calling of image to image and synchrodata.
Summary of the invention
The present invention is directed to the particularity demand of image lossless record, increased the digital communication module that can realize acquisition and recording control module and the information exchange of digital communication subsystem on the basis of existing technology, and the relevant application software of exploitation, purpose provides a kind of digital-image non-loss recorder, satisfies the user the real-time synchronous recording and the calling of image of image and synchrodata are browsed.
The present invention is by image capture module 1, acquisition and recording control module 2, data communication module 3 and Imagery Data Recording module 4 are formed, image capture module 1 view data output links to each other with acquisition and recording control module 2 view data inputs, acquisition and recording control module 2 measurement data inputs link to each other with the system status parameters data input pin with data communication module 3 measurement data outputs respectively with the system status parameters data output end, the view data of acquisition and recording control module 2 links to each other with externally measured data input pin with Imagery Data Recording module 4 view data with externally measured data output end, and data communication module 3 measurement data inputs are connected with the digital communication subsystem with the system status parameters data output end.
The course of work of the present invention: acquisition and recording control module 2 is gathered and dumped to the image by the gamma camera collection through image capture module 1, acquisition and recording control module 2 is carried out data communication by data communication module 3 and digital communication subsystem simultaneously, synchronously the externally measured data of receiving system.The major function of acquisition and recording control module 2 is the work that coherent system is respectively formed intermodule, the data that collect are handled, deposit view data that collects and the externally measured data in real time of system that receives synchronously in Imagery Data Recording module 4, monitoring system each several part operating state simultaneously, and with the status data of system; Comprise that disk size, system mode etc. send to external control devices by data communication module 3, digital communication subsystem.Imagery Data Recording module 4 can realize the total data that collects is carried out the real time high-speed storage.
In order to make system under the control of acquisition and recording control module 2 program command, finish the task of the real-time synchronous recording of image and synchrodata, work out primary control program in advance, and it is deposited in the memory of acquisition and recording control module 2.
Primary control program comprises the following steps:
A. begin;
B. the internal memory to image capture module 1, data communication module 3, acquisition and recording control module 2 carries out the initialization setting, and thread is set, to the parameter assignment;
C. judging whether externally measured data of system and view data are carried out record, be that then program changes steps d over to, otherwise program changes step g over to;
D. deposit externally measured data of system and view data in acquisition and recording control module 2 internal memories;
E. judging whether acquisition and recording control module 2 internal memories are full, be that then program changes step f over to, otherwise program is returned steps d;
F. start the storage thread, deposit data in Imagery Data Recording module 4, program is returned step c;
G. carry out picture browsing afterwards;
H. judging whether bolt down procedure, is that then program changes step I over to, otherwise program is returned step c;
I. finish.
The present invention can realize the synchronous acquisition and the storage of image and external data, and the mode to image employing non-loss recording helps to carry out graphical analysis afterwards.The present invention has reached alignment of data and has not had the effect of losing, going here and there frame for the record of image and data.At the demand of view data flow less than 50MB/s, the present invention all can meet the demands.
