【摘要】：集成式相机阵列高速摄像机与传统单镜头高速摄像机在同等帧率上相比拥有体积小,成本低的特点。本文是基于3*3集成式阵列相机,采用CMOS图像触感器,每个相机的帧率为30fps。文章主要介绍了阵列相机高速摄像原理,阵列相机图像存储与显示时图像格式的选择,和对阵列图像高速运动物体去模糊的算法研究。首先从多相机阵列,交错式高速摄像,几何校正,辐射校准,克服电子卷帘式快门五个方面详细阐述了阵列相机高速摄像原理。其次,讨论了BMP、JPG和RAW图像格式的优缺点,得出为了保证数据传输的完整性,后期图像处理的准确性,RAW图像格式更适合阵列相机。重点研究了局部运动图像复原算法和改进倒频谱图像去运动模糊算法,实现阵列相机图像去运动模糊。阵列相机高速摄像技术在国内受到极高的重视,本文成果有望为集成阵列式高速摄像机产业化提供技术支持。
[Abstract]:The integrated camera array high speed camera has the advantages of small size and low cost compared with the traditional single lens high speed camera in the same frame rate. This paper is based on the 3Q3 integrated array camera, using CMOS image tactile device, the frame rate of each camera is 30fps. This paper mainly introduces the principle of high speed camera of array camera, the choice of image format when storing and displaying the image of array camera, and the research on the algorithm of deblurring high speed moving object of array image. Firstly, the principle of high speed camera of array camera is described in detail from five aspects: multi camera array, interlaced high speed camera, geometric correction, radiation calibration and overcoming electronic shutter. Secondly, the advantages and disadvantages of BMP,JPG and RAW image formats are discussed. In order to ensure the integrity of data transmission and the accuracy of the later image processing, the RAW image format is more suitable for array cameras. The local motion image restoration algorithm and the improved cepstrum image de-motion blur algorithm are studied in order to realize the array camera image de-motion blur. The high speed camera technology of array camera has been attached great importance in our country. The results of this paper are expected to provide technical support for the industrialization of integrated array high speed camera.
