示值與誤差
英文
indications and errors-
Experiment results show : ? he theory and method of information content could play an important role in the case study on the accuracy and application of dem. ( 2 ) in the loess plateau area, there are much difference between 5m resolution dems of 1 : 10000 map scale and 25m resolution dems of 1 : 50000 map scale while gathering terrain characteristic information, and yet the spatial structure of dem error have discipline and measurability on statistics. ( ? the results could offer fundamentals and methods to people on their work to research the terrain information content of dems with different scale level
研究結果顯示： 1 、地形信息容量的理論與方法對于dem精度與應用適宜性的研究具有重要的作用； 2 、在黃土丘陵溝壑區，同1 ： 1萬比例尺5米解析度的dem相比， 1 ： 5萬比例尺25米解析度dem在提取地形特徵方面具有較大的差異，但誤差的量值與空間分佈具有統計上的規律性與可估算性； 3 、以上研究結果可望為其它各級比例尺dem地形信息容量的研究提供新的理論基礎與技術方法，也可為有關規范、標準的制定提供依據。Simultaneously with the micro - displacement started the processe of the grating sensor measuring the displacement and image collection of the system. the grating sensor ( length gauge ) measures the displacement of the dial gauge with surveying rod. it is delivered to the computer with a block k220 in real time and the dial image by ccd camcorder is shown on the computer screen with the image collection card in real time
在實現微量進給的同時，啟動系統的光柵位移測量過程和圖像採集過程，光柵傳感器（長度計）測得指示表測桿的位移量，由計數卡ik220實時傳送給計算機，由ccd攝像頭攝取的表盤圖像經圖像採集卡在計算機屏幕上得以實時顯示，最後通過對指示表指針位移計算處理與光柵傳感器測量的位移量進行比較，得到指示表受檢點的示值誤差。Motion compensated prediction error image has significant amplitudes mainly along the boundaries of moving objects, correspondingly its wavelet coefficients contain large energy in high frequency bands. this greatly reduces the coding efficiency of ezw. it is first provided that the correspondence between the significant amplitudes area of the mcp error image and the wavelet coefficient significant map, then encode the significant map efficiently using quadtree approach, followed by bit - plane coding the significant coefficients to produce an embedded data stream. experiment result shows that compared to ezw and zte, the proposed algorithm is more efficient and has better performance
演算法對于運動補償余量誤差幀首先進行小波變換，並選取適當的閾值，用重要圖表示大於該閾值的重要系數。根據殘差幀小波系數的統計特性，用四叉樹方法編碼重要圖，並對重要系數作位面編碼，生成嵌入式碼流。實驗表明，與ezw ， zte等演算法相比較，該演算法編碼效率高，復現圖像質量好。
