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

The invention discloses a large area array high frame rate image acquisition device, comprising: two large area array digital CCD input modules, two video conditioning modules, digital video processing modules, two image storage modules, large area array high frame frequency digital video output module. Send the image information of the two digital image sensors to the two video conditioning modules respectively. The video conditioning module parses the image information of the large area array digital CCD input module into data signals, clock and synchronous signals and sends them to the digital video processing module. The digital video processing module generates an external synchronous trigger signal and a timing signal of a high frame rate image, and controls frame image storage at the same time. The image storage module is used for frame image buffering and storage. The large area array high frame rate digital video output module encodes the high frame rate digital video output by the digital video processing module into different video formats for output. The invention can not only realize the high frame frequency acquisition of two CCDs, but also can be extended to the high frame frequency acquisition of multiple CCDs, and can be directly applied to the image processing platform with high frame frequency and large area array.
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 large area array CCD images of the same type, etc. Background technique [0002] With the development of photoelectric detection technology, it is necessary to provide a digital CCD with large area array and high frame rate. However, the output frame frequency of the existing large area array and super large area array digital CCD is relatively low, which is difficult to adapt to the photoelectric detection system for high-speed changing targets. Probing 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 increased ...
