【摘要】:随着空间生命科学的发展和航空航天技术的进步,人类对宇宙的探索和认识不断深化,空间生命科学研究的内容和范畴日趋广泛,在认识生命现象本质、促进知识创新和技术创新,保障人类健康生活、促进生物技术的创新发展和应用,拓宽人类生存疆域、促进必要技术的储备和发展等方面将发挥无法替代的作用。根据空间生命科学与生物技术领域的研究现状及发展情况,生命科学实验平台以分子、细胞、组织、个体及群体等不同层次的生物样品为研究对象,研究生物样品的生命活动在空间特殊环境下所发生的变化,而生物的光信息与生物的生命活动密切相关,因此对这些生物的光信息进行准确、高效、针对性强地处理,对生命科学研究起着非常重要的作用。本课题在这个背景下提出生物光信息处理技术,主要研究内容和成果如下:1)对空间植物培养箱中彩色CMOS图像传感器获取的生物光信息进行色彩还原,色彩校正和色彩增强。通过对比不同的色彩还原、色彩校正、色彩增强方法,提出一种适合空间培养的植物图像色彩还原,色彩校正方法。2)针对空间荧光显微成像系统中获取的动物细胞图像背景噪声比较大,对比度不够强的特点,提出一种对比度拉伸方法,突出了图像的目标特性,提高了图像的信噪比。3)本课题对基于微透镜型的光场成像技术进行研究,采用计算成像的方式对获取的空间光场信息进行算法处理,实现通过一次拍照获取聚焦在不同深度的图像,实现空间物体的三维立体重构,研究目的是为把光场成像技术应用到空间生命科学研究领域中做铺垫。4)在上述生物光信息处理技术研究的基础上开发基于MFC的空间生物图像处理软件平台,实现生物光信息处理的可视化和便捷化。
[Abstract]:With the development of space life science and the progress of aerospace technology, the exploration and understanding of the universe have been deepened, and the contents and categories of space life science research have become more and more extensive. To promote knowledge innovation and technological innovation, to ensure a healthy life for human beings, to promote the innovative development and application of biotechnology, and to broaden the scope of human survival. Promoting the reserve and development of necessary technologies will play an irreplaceable role. According to the current research situation and development situation of space life science and biotechnology, the life science experimental platform is based on molecules, cells and tissues. Biological samples at different levels, such as individuals and populations, are studied to study the changes of biological life activities in special space environment, and the biological light information is closely related to biological life activities. Therefore, it is very important to deal with the light information of these organisms accurately, efficiently and pertinently, which plays a very important role in the research of life science. Under this background, this paper puts forward the technology of biological light information processing. The main research contents and results are as follows: 1) Color reduction of bioluminescence information obtained by color CMOS image sensor in space plant incubator. Color correction and color enhancement. By comparing different methods of color restoration, color correction and color enhancement, a plant image color restoration suitable for space culture is proposed. Color correction method. 2) aiming at the characteristics of large background noise and low contrast of animal cell images obtained in spatial fluorescence microscopic imaging system, a contrast stretching method is proposed. Highlight the target characteristics of the image and improve the signal-to-noise ratio of the image. The algorithm is used to process the information of the spatial light field by computer imaging, and the 3D reconstruction of the spatial object can be realized by taking a photograph to obtain the image focused at different depth. The purpose of this study is to lay the groundwork for the application of light field imaging technology in the field of space life science. On the basis of the above research on the bio-optical information processing technology, the software platform of space biological image processing based on MFC is developed. The visualization and convenience of bio-optical information processing are realized.
