【摘要】：針對(duì)現(xiàn)有接邊方法依賴于直線型接邊線,難以有效的支持非直線型接邊線的數(shù)據(jù)接邊質(zhì)量檢驗(yàn)的問(wèn)題,提出了一種新的基于距離與角度控制的矢量面數(shù)據(jù)接邊檢查方法。該方法利用矢量面到接邊線的距離值與弧段轉(zhuǎn)角角度值作為參考量檢測(cè)接邊特征點(diǎn),通過(guò)匹配接邊特征點(diǎn)的方式檢測(cè)接邊錯(cuò)誤位置,不依賴于接邊線的具體形態(tài),能夠適用于任意類(lèi)型接邊線的矢量面數(shù)據(jù)接邊檢查。以第一次全國(guó)地理國(guó)情普查數(shù)據(jù)接邊檢驗(yàn)為實(shí)例進(jìn)行驗(yàn)證,結(jié)果表明,該方法的漏檢率為0%,準(zhǔn)確率達(dá)到95%以上,有效地提升了接邊線非直線的矢量面數(shù)據(jù)接邊質(zhì)量檢驗(yàn)的準(zhǔn)確性及效率。
[Abstract]:Aiming at the problem that the existing edge-connecting method is difficult to effectively support the quality inspection of the data of the non-linear connection line, a new method for edge checking of the data of the vector surface based on the distance and the angle control is proposed. the method uses the distance value of the vector surface to the ground line and the angle value of the arc-segment angle as the reference quantity to detect the edge-receiving characteristic point, And can be applied to the edge checking of the vector surface data of any type of connection line. The results show that the error rate of the method is 0%, the accuracy rate is over 95%, and the accuracy and efficiency of the quality inspection of the non-linear vector surface data of the ground line are effectively improved.
