超高分辨率光电探测图像预处理系统设计

Design for Ultra-high Resolution Image Pre-process System for Photoelectric Detection

当前超高分辨率光电探测设备的图像采集预处理需借助于专用采集卡和处理系统才能显示,且现有采集卡对超高分辨率光电设备获取的图像信息不能完全采集。本文以超高分辨光电探测设备使用的特大面阵CCD为原型,设计了一种图像预处理系统,完成光电探测设备输出图像的后处理及显示任务。实验结果表明本文所设计的系统能实时处理并显示超高分辨率光电探测设备的特大面阵CCD拍摄的图像,能观察不同分辨率的图像以及原图像任何部位的细节,并能根据实际观察效果调整显示亮度以更好地观察图像,解决了现有采集卡无法完整采集巨幅图像以及巨幅图像的拼接问题。

The image acquisition and preprocessing from photoelectric detection equipment of ultra-high resolution needs special acquisition card and processing system to display,and the existing acquisition card cannot fully capture the image that information acquired by ultra-high resolution photoelectric equipment at present.In this paper,an image pre-processing system is designed based on the super-large area array CCD used in the ultra-high resolution photoelectric detection equipment that complete the post-processing and display tasks of the output image of the photoelectric detection equipment.The experimental results show that the system designed in in this paper can process and display the image in real-time,which taken by the super-large area array CCD of the ultra-high resolution photoelectric detection equipment,can observe the image of different resolutions and the details of any part of the original image,and can adjust the display brightness according to the actual observation effect to better observe the image,solving the problem that the existing capture card cannot completely image acquisition and Image mosaic for the huge image.
