  1. According to the characteristic of ieee 1394 with wide bandwidth, common and real - time, the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite. before engineering realization, carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface. we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4. 5m to 100m ), compared with analog videos, have no geometric distortion, and have better luminance, contrast, definition

    作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。
  2. In video shot segmentation, an improvement to double - threold shot segmentation algorithm is provided, which uses multi - frame sampling technique and can improve the performance significantly on the detection of gradual transition. an abrupt transition detection algorithm is also developed on the basis of the closest pixels matching in spatio - temporal slice, which decreases the false rate and computing strength greatly

    在視頻鏡頭分割方面，提出了一種基於多幀抽樣的雙重比較鏡頭分割演算法，有效地提高了對視頻鏡頭漸變檢測的性能;同時，針對視頻鏡頭突變的檢測，提出了一種基於最近鄰像素匹配的時空切片鏡頭突變檢測演算法，該演算法顯著降低了突變檢測的虛檢率和計算量。
  3. Finally proceed a series of tests by adopting different surface types to memory and display images, and then analyze the test data of cpu cost and frame display rate, also compare the quality of display, finally draw a conclusion : the method of images display based on directdraw has higher efficiency than on gdi, especially overlay project

    測試採用directdraw不同的表面類型來存儲圖像數據並完成顯示，通過對cpu佔用率和顯示幀速率數據的分析，以及顯示質量的比較，最後得出基於directdraw技術的快視系統其顯示效率高於基於gdi的快視系統，對系統資源的佔用降低， cpu佔用率在預期范圍之內。
  4. This paper emphatically researched the problem how to calculate the intersection point between workpiece that rotated with variational angle velocity and milling cutter that moved with complicated track and rotated with high speed. furthermore it adopted the discrete curve surface method for every milling cutter, and treated image frame as the control parameter of position of milling cutter during the intersection calculation process, so the algorithm of intersection between workpiece and milling cutter was obtained. the paper also discussed further three - dimension graphic problem of manufacture process

    文中對做變角速度運動的工件和運動軌跡復雜的高速自轉中的銑刀求交問題進行了重點研究，採用將銑刀上的每個刀尖劃出的曲面離散化的方法，以圖像顯示的幀數作為求交計算過程的銑刀位置的控制參量，得出了銑刀與工件的求交演算法。
