Abstract

The invention relates to the field of airborne video acquisition, particularly to a high-resolution airborne video acquisition structure that can be applied to high-resolution, low-frame-rate ARINC818 fiber video signal conversion to solve an acquisition problem of a high-resolution airborne video so as to provide timely and reliable video data for various flight tests in the aviation test flight field. The high-resolution airborne video acquisition structure comprises a photoelectric conversion module, a video conversion module and an FPGA control module. An ARINC818 optical signal is converted into an ARINC818 electrical signal by the photoelectric conversion module; the converted signal is sent to the video conversion module; the video conversion module converts the ARINC818 electrical signal into two paths of DVI signals for outputting; the video conversion module also sends the ARINC818 electrical signal to the FPGA control module; and the FPGA control module carries out decoding, caching, and reading on the ARINC818 electrical signal and frame insertion as well as DVI coding outputting is carried out.

Description

technical field [0001] The invention belongs to the field of airborne video acquisition, and in particular relates to a high-resolution airborne video acquisition structure. Background technique [0002] Since the airborne display and control system adopts ARINC818 transmission mode, and the video resolution is 2560*1024 / 30fps. However, the current airborne video capture equipment can only capture digital videos in DVI formats such as 1600*1200 / 60fps, 1600*1200 / 30fps, 1280*1024 / 60fps, 1024*768 / 60fps, 1024*768 / 30fps, etc. Realize ARINC818 bus data acquisition of 2560*1024 / 30fps. Contents of the invention [0003] In view of this, the present invention provides a kind of high-resolution airborne video acquisition structure, and it can be used for the conversion of high-resolution, low frame frequency ARINC818 optical fiber video signal, solves the acquisition problem of high-resolution airborne video, and is aeronautical test flight Provide timely and reliable video data f...
