Large-area-array and high-frame-rate image collection device

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.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, and relates to a large area array digital CCD high frame rate image acquisition device and method, which is mainly applied to the high frame rate acquisition of two large area array CCD images of the same model, and can also be extended to multiple High frame rate acquisition of CCD images of the same model with large area array, etc. Background technique [0002] With the development of photoelectric detection technology, it is necessary to provide digital CCD with large area array and high frame rate. However, the output frame rate of existing large area array and super large area array digital CCD is low, so it is difficult to adapt to the requirements of photoelectric detection system for high-speed changing targets. detection and high frame rate output requirements. In order to increase the output frame rate of the large area array digital CCD, the detection frame rate can be increase...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that a single large area array digital CCD has a low output frame rate and cannot meet the detection requirements for high-speed changing target detail information. Therefore, a large area array high frame rate image acquisition device is provided. It can meet the camera system composed of two or more large area array digital CCDs at the same time, ensuring the requirements of digital CCD large area array and high frame rate, which can not only meet the requirements of target detection field of view, but also meet the requirements of high-speed changing target details Information Probing Requirements
