針對微型航天探測器在星空運(yùn)動背景下對目標(biāo)識別的要求，提出一種基于圖像配準(zhǔn)與
邊緣提取的差分算法。該算法將采集的連續(xù)兩幀圖像配準(zhǔn)后差分，將差分圖像二值化后與后一幀邊緣提取后的圖像進(jìn)行邏輯乘，提取出目標(biāo)物。計(jì)算機(jī)仿真結(jié)果表明該算法計(jì)算量小，識別效果好。
關(guān)鍵詞：微型航天探測器；差分；圖像配準(zhǔn)
Abstract: In order to meet the needs of detecting the target under the moving space background by microspacecraft target detector .This paper proposed an algorithm-the image edge extract and deference base on image registration. The algorithm use image difference to the two collected and seriate image after image registration, then multiply the difference image after binarizing and the second image after edge extract by pixel, then detect the target. The result of simulation indicate that computational effort is low and detected result is good.
