【摘要】：光場(chǎng)成像作為一種應(yīng)用廣泛的計(jì)算成像方法,其研究仍局限于電磁波譜中的可見光波段。因此,提出基于相機(jī)陣列的紅外光場(chǎng)成像方法。首先利用單臺(tái)被動(dòng)紅外相機(jī)移動(dòng)到同一平面的不同位置分別對(duì)同一靜態(tài)目標(biāo)場(chǎng)景成像,獲取原始紅外圖像序列,經(jīng)平移視差校正后生成紅外光場(chǎng)數(shù)據(jù)庫(kù);然后基于光場(chǎng)渲染理論,獲得重采樣圖像。與只記錄二維位置信息的傳統(tǒng)紅外成像比較,紅外光場(chǎng)成像能夠記錄包含位置和方向的四維信息。實(shí)驗(yàn)結(jié)果表明,該法能夠融合多幅低信噪比的圖像獲得一幅信噪比提高的重采樣圖像,通過(guò)孔徑疊加平均可實(shí)現(xiàn)穿透遮擋物成像,通過(guò)選取不同深度值進(jìn)行重采樣可實(shí)現(xiàn)紅外場(chǎng)景不同深度的數(shù)字重聚焦,使紅外成像在軍事和民用領(lǐng)域更有應(yīng)用價(jià)值。
[Abstract]:As a widely used computational imaging method, optical field imaging is still limited to the visible band of the electromagnetic spectrum. Therefore, the infrared field imaging method based on the camera array is proposed. First, a single passive infrared camera is used to move to the same plane to image the same static target scene, and the original red is obtained. The external image sequence is corrected by translation parallax correction to generate the infrared field database, and then the resampling image is obtained based on the light field rendering theory. Compared with the traditional infrared imaging that only records two-dimensional location information, infrared field imaging can record four dimensional information containing the position and direction. The experimental results show that the method can fuse multiple low signal noise. A resampling image with improved signal to noise ratio is obtained by comparing the image to the image. The image can be achieved through the average aperture superposition, and the digital refocusing of different depth of the infrared scene can be realized by the selection of different depth values. The infrared imaging is more valuable in military and civil fields.
