surface local feature

基本解釋

The whole feature parameters and local feature of spacial geometric features of road surface are put forward.
提出了表征路面表面空間幾何特征的整體特征參數(shù)和局部特征參數(shù)。
Based on the feature of anisotropy of machining width on the local of the free-form surface, a tool-path planning method of optimal cutting direction field is given.
同時，基于復(fù)雜曲面加工的局部各向異性特征，給出了一種具體的基于最優(yōu)切削方向場的刀具路徑規(guī)劃方法。
Instead of traditional background prediction, this method detects infrared small and dim target by judging whether the local grey level surface possesses the two dimension Gauss function feature.
該方法通過判斷圖像局部灰度包絡(luò)曲面是否具備二維高斯函數(shù)曲面特征實現(xiàn)紅外弱小目標(biāo)檢測，不需要進(jìn) 行傳統(tǒng)的背景預(yù)測。
