The laser beam treated as a linear reference is used widely in the manufacture and measurement equipments, due to its many advantages, such as high brightness, good directivity, and good coherence etc. but the further improvement of the laser directional stability accuracy is restricted by some factors, such as the environment etc, which restrain the application greatly in the ultra - precision manufacture and measurement equipments
激光光束由於其亮度高、方向性好、相干性好等優點，常被作為直線基準廣泛應用於加工和測量設備中。但由於受環境狀態等因素的影響，制約了激光方向穩定精度的進一步提高，限制了激光在超精密加工和測量設備中的進一步應用。A llmmse filter is designed to reduce noise based on the noise model to improve snr of images. making use of the shape and lightness characters of feature points to detect the feature p oints from images. because the accuracy of feature imaging point ' s centroid has close relationship with measuring accuracy, an algorithm based on iteration of the center of the track window is used to improve the measurement accuracy
圍繞著提高測量精度的要求，分析了影響ccd圖像質量的三類隨機噪聲，建立局部統計特性為高斯分佈的簡化圖像噪聲模型，利用線性最小均方誤差濾波器對圖像進行預處理，而後根據特徵點的亮度和形狀特徵對特徵像點進行檢測，進一步在特徵像點的匹配中採用自適應的質心迭代演算法提高跟蹤精度。In the knowledge economy era enterprising spirit and practical ability are the elementary factors which can affect the whole nation ' s development. so the new basic education curriculum innovation advances changing the status quo which overemphasizes receptive learning, memorizing and practicing mechanically. it advances a way of learning which is automous, cooperative and inquiry learning
在知識經濟時代，創新精神與實踐能力成為影響整個民族生存狀況的基本因素，因此，新一輪課程改革提出要改變教學過于強調接受學習、死記硬背、機械訓練的現狀，大力倡導自主、合作、探究的學習方式，建立和形成旨在充分調動學生主動參與、發揮學生主體性的探究教學成為了此次課程改革中的一個亮點。
