Abstract

The present invention discloses a target simulator real-time drive system based on a DVI interface of a graphics card. The system comprises: a DVI transmission interface, used for establishing a data communication with a graphic workstation and a target simulator; a synchronous transmission control module, used for sending a simulation start signal to a dynamic scene image simulation module based on a field frequency signal output by the DVI transmission interface, and establishing synchronous data transmission with the target simulator; and the dynamic scene image simulation module, used for performing simulation analysis on to-be-tested dynamic scene data acquired from an external device based on the simulation start signal, and storing simulation image data into a frame cache. The present invention further discloses a target simulator real-time drive method based on a DVI interface of a graphics card. The technical scheme provided by the present invention shortens radiation scene output delay, ensures delay stability and thus greatly improves confidence of semi-physical dynamic scene simulation.

Description

Technical field[0001]The present invention relates to image data transmission, and more particularly to a target simulator real-time drive system and method based on a graphics DVI interface.Background technique[0002]Dynamic image scene simulation is an important part of semi-real simulation test. Image Computer Graphics GPU has powerful graphical rendering and parallel computing power, currently the mainstream complex scene modeling software platform at home and abroad is all based on graphics engine. The graphic computer generated simulation scene image is output to the target simulator refresh to generate radiation scenarios by the graphics card standard DVI interface. However, due to the industrial standards of video transmission, there is an inherent transmission delay. After testing, the frame rate is 100 Hz, from the image generated computer receiving the simulation host real-time mesh, to the target simulator generates simulation scene, test is greater than 40 ms unstable de...
