例句與用法

1. It can save many workloads of the next pick - up feature and feature matching . to suffice third dimension effect and reconstruction precision , first , obtain enough feature points by feature picking - up , and then use original matching arithmetic to obtain original matching points by taking covariance as comparability measurement . at last , match step by step that include use loose matching and lemds to remove the wrong matching points
   為滿足真實感效果和重建精度,本文先通過特征提取和交叉匹配獲得足夠多的特征點;然后對采集到的特征點以協(xié)方差為相似性度量,利用初始匹配算法獲得初始匹配點集合;對匹配過程中產(chǎn)生的錯誤匹配點采用松弛匹配和最小中值法相結(jié)合的方法,進行分步匹配來剔除,滿足了精度要求。
2. The pairwise matching of feature points in each resolution is the emphasis of our discussion . an improved method based on mapping is adopted to find the best match of each feature point . experimental results show that it can effectively reduce the number of wrong matches , thus increase the precision of image stabilization
   重點研究了金字塔每層中特征點匹配問題，提出了利用前后映射尋找一一對應(yīng)特征點的方法，實驗結(jié)果表明，該方法能有效排除錯誤的特征點配對，從而減少運動參數(shù)估計的誤差。
