本文實現的h . 264編碼器性能為:在主頻為720mhz的tms320c6416晶元上對2路qcif格式的視頻圖像進行處理，在一定的保真度條件下，編碼速度達到了27 . 5幀/秒。This method is especially suitable for small mobile devices such as handheld pcs, palm - size pcs and mobile phones that possess small display screens and light computational power, and work in low bandwidth wireless networks. the system rtbvideo based on the technique mentioned above typically provides qcif - size video with a frame rate of 5 - 15 fps for a 9. 6 kbps bandwidth in the internet
在上述技術的基礎上開發的基於internet網際網路的實時視頻傳輸系統rtbvideo ，能夠提供格式為qcif （ 176 144 ）的視頻，人體輪廓清晰，畫面穩定流暢，且在9 . 6kbps帶寬下能達到每秒5 - 15幀。The main contents of the study include such aspects as follows : ( 1 ) the moving vehicle auto - detecting grid arithmetic is studied and presented on the basis of the idea of the image difference arithmetic. the moving vehicle is detected whether or not to enter the field of view by calculating the grid dissimilarity between the current frame image and the reference frame image. dsdr ( dissimilarity descend rate ) is defined, and by calculating it the position of the moving vehicle in grids can be determined exactly, so the vehicle model image can be saved conveniently
本文所進行的研究主要包括以下方面： （ 1 ）在圖像差分演算法基礎上，研究提出了運動車輛自動檢測的柵格演算法，該方法通過計算當前幀與參考幀對應柵格的不相似度來檢測是否有運動車輛進入視場；定義了不相似度下降率dsdr ，基於此，可以比較準確地確定出運動車輛在柵格中的位置，並可方便地將車輛圖像作為模板保存下來。Abstract : some problems about overall design of a small unmanned air vehicle telemetry system are presented in this paper. the construction and fundamental principle of the telemetry system is simply introduced. according to the telemetry task requirement, the key problems which should be solved at first are demonstrated mainly by system " s capacity design and channel design. the needed data transmission rate is carefully calculated with the telemetry parameter table provided by user and on this basis the frame structure is decided. the bit error rate in factual telemetry channel is grossly estimated in theory and a channel encoding scheme is provided to improve data transmission quality to meet with the requirement for extremely low bit error rate
文摘:論述了某型號無人機遙測系統中的容量和通道設計問題.文中對該遙測系統的組成和原理進行了介紹.結合具體的遙測任務需求，在容量設計中確定了數據傳輸率和使用的幀格式，在通道設計中，通過計算實際通道中的誤碼率，提出了相應的通道編碼方案以確保數據傳輸的低誤碼率要求I also analyze the physical layer, data link layer and the progress of the protocol, etc. then i introduce the algorithm of automatic repeat request and calculate the utilization ratio of the link
