| 中文摘要 | 本研究聚焦於視訊式遙測衛星的發展與其影像去模糊化之分析。視訊式衛星透過高時間 解析度的連續動態影像,能有效彌補傳統靜態衛星影像在時間連續觀測上的不足,並在智慧 監控、災害應變及城市規劃等領域具有顯著潛力。然而,影像解析度低、衛星運動造成的模 糊,以及劇烈照明變化所引起的影像失真,嚴重限制其進一步應用。本研究針對此問題,利 用兩階段金字塔式影像去模糊技術,透過模糊核估計與反卷積重建方法,提升視訊衛星影像 品質。實驗使用 SkySat 視訊影像進行測試,結果顯示使用單一模糊核重建的影像,其峰值 訊噪比與結構相似性顯著提升,證明該技術能有效改善影像的細節呈現與整體視覺品質,推 動視訊衛星影像在動態目標監測及細節分析的實務應用。 |
| 英文摘要 | This study focuses on the development of video-based remote sensing satellites and the application of image deblurring techniques. Video-based satellites, capable of capturing continuous dynamic image sequences with high temporal resolution, effectively address the limitations of traditional static remote sensing imagery in continuous temporal observation. These capabilities offer significant potential in fields such as intelligent monitoring, disaster response, and urban planning. However, further applications are restricted by challenges like low spatial resolution, motion-induced blur caused by satellite movement, and distortion from rapid illumination changes. To overcome these issues, this research employs a two-stage pyramid-based deblurring approach, using kernel estimation and deconvolution reconstruction methods to enhance satellite video imagery quality. The experimental evaluation conducted with SkySat satellite imagery demonstrates that images reconstructed using a single average blur kernel signifi cantly improved peak signal-to-noise ratio and structural similarity index, indicating effective recovery of fine details and overall visual clarity. These improvements support advanced image analysis tasks, including dynamic object monitoring and detailed feature analysis, thus significantly enhancing the practical applications of satellite video imagery. |
