【摘要】：集成式相機(jī)陣列高速攝像機(jī)與傳統(tǒng)單鏡頭高速攝像機(jī)在同等幀率上相比擁有體積小,成本低的特點(diǎn)。本文是基于3*3集成式陣列相機(jī),采用CMOS圖像觸感器,每個(gè)相機(jī)的幀率為30fps。文章主要介紹了陣列相機(jī)高速攝像原理,陣列相機(jī)圖像存儲(chǔ)與顯示時(shí)圖像格式的選擇,和對(duì)陣列圖像高速運(yùn)動(dòng)物體去模糊的算法研究。首先從多相機(jī)陣列,交錯(cuò)式高速攝像,幾何校正,輻射校準(zhǔn),克服電子卷簾式快門五個(gè)方面詳細(xì)闡述了陣列相機(jī)高速攝像原理。其次,討論了BMP、JPG和RAW圖像格式的優(yōu)缺點(diǎn),得出為了保證數(shù)據(jù)傳輸?shù)耐暾?后期圖像處理的準(zhǔn)確性,RAW圖像格式更適合陣列相機(jī)。重點(diǎn)研究了局部運(yùn)動(dòng)圖像復(fù)原算法和改進(jìn)倒頻譜圖像去運(yùn)動(dòng)模糊算法,實(shí)現(xiàn)陣列相機(jī)圖像去運(yùn)動(dòng)模糊。陣列相機(jī)高速攝像技術(shù)在國(guó)內(nèi)受到極高的重視,本文成果有望為集成陣列式高速攝像機(jī)產(chǎn)業(yè)化提供技術(shù)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.
