pas de bourre en tournant en dedans-
There is a pretty strict limit of reliability, cost, volume and energy - consuming. real - time embedded control system is applied for firm real - time and responding circumstance. aiming at direct current servo electromotor, a set of servo experiment system is designed, exploitation flow and process of real - time embedded control system are advanced, some issues of them are paid much more attention, the satisfied effects are obtained in the real circumstance, these issues include : exploitation of embedded system, analysis of superiority of the exploitation, the exploitation of embedded linux operation system from kernel customizing and file system cutting out to system starting up is researched, some factors which effect the system ' s capability are analyzed, the settled real - time schemes of linux os and the arithmetic of preemptive priority scheduling and round - robin scheduling and latest and rapid arithmetic are researched
本文圍繞著針對直流伺服電機設計一套伺服試驗系統，對于嵌入式實時控制系統應用技術進行了比較全面的研究，提出了嵌入式實時控制系統的開發流程和步驟，並對其中的一些問題進行了專門研究，在實物實驗中獲得了比較好的效果，這些問題包括：嵌入式操作系統開發，分析了使用linux操作系統進行嵌入式操作系統軟體開發的優越性，並且從內核定製、文件系統裁剪、系統啟動等幾個方面研究嵌入式linux操作系統的開發；實時性研究，分析了在操作系統中影響系統實時性能的因素，研究了linux操作系統的幾種實時解決方案，並且研究了基於優先級的可搶占式與可選擇的同優先級按時間片輪轉相結合的調度演算法以及最遲響應與最快處理的可搶占式調度演算法。The algorithm takes advantage of the merits of the watermarks both in low frequency and high frequency and can embed more information with less distortion. experimental results show the algorithm is robust to many common image operations. as for the vector map data, an uniform model of embeding watermark for vector maps and raster maps is proposed after current trend of research and watermarking methods of 3 - d vector images are summarized, primary study results show the model is effective and promising to further research
目前該問題在國內外都還處于探索階段，作者在分析了國內外三維矢量水印的研究狀況、研究方法后，提出了將矢量數據中的部分信息轉化為柵格形式后再嵌入水印的方法，該方法使地圖柵格數據和矢量數據在嵌入水印時能夠使用統一模型，初步的實驗結果表明該方法為二維地圖矢量數據的水印嵌入開辟了一種新途徑。
