Example Embodiment

[0042] The present invention will be described below in conjunction with specific embodiments:

[0043] The present invention mainly solves the problem that the output frame rate of a single large-area digital CCD is low and cannot meet the detection requirements of high-speed changing target detail information. It provides a large-area high-frame-rate image acquisition device that can meet two or The camera system composed of multiple large area array digital CCDs guarantees the requirements of large area array and high frame rate of digital CCD, which can not only meet the requirements for the target detection field of view, but also meet the requirements for the detection of high-speed changing target details.

[0044] The acquisition device provided by the present invention includes: a first large area array digital CCD input module, a second large area array digital CCD input module, a first video conditioning module, a second video conditioning module, a digital video processi...

Abstract

The invention discloses a large-area-array and high-frame-rate image collection device comprising two large-area-array digital CCD input modules, two video conditioning modules, a digital video processing module, two image storage modules and a large-area-array and high-frame-rate digital video output module. The image information of two paths of digital image sensors is separately sent to the twovideo conditioning modules. The video conditioning modules analyze the image information of the large-area-array digital CCD input modules into data signals, clock signals and synchronizing signals and send the data signals, the clock signals and the synchronizing signals to the digital video processing module. The digital video processing module generates an external synchronization trigger signal and a timing sequence signal of a high-frame-rate image, and meanwhile controls the storage of a frame image. The image storage module is used for buffering and storing the frame image. The large-area-array and high-frame-rate digital video output module encodes a high-frame-rate digital video output from the digital video processing module into different video formats and outputs the same. Thelarge-area-array and high-frame-rate image collection device disclosed by the invention can not only realize the high-frame-rate collection of two paths of CCDs, but also can be expanded to realize the high-frame-rate collection of multiple paths of CCDs, and the large-area-array and high-frame-rate image collection device can be directly applied to a high-frame-rate and large-area-array image processing platform.
