A new algorithm is presented for recognizing planar objects from a line drawing under axonometric and perspective projections based on principle of homograph
基於類似形的定義給出了在透視投影下平面多邊形為類似形的識別演算法。 -
The topological structure is introduced to analyze homograph qualitatively, the algorithm is robust and insensitive to noises of images. the geometrical structure is used to analyze homograph quantitatively, the fine discrimination between planar objects can be shown
該識別方法對類似形應用拓撲結構進行定性分析，對噪音不敏感；同時結合幾何結構對類似形進行定量分析，能反映平面立體形狀的細微差別。 -
We introduce five topological characteristics and geometry characteristics that are invariant under projective transformation specially perspective projection. the definition of homograph is given by means of these characteristics, and then the recognizing method of the homograph is proposed according to the definition of homograph
接著，根據透視投影不變性提出了5個用來描述多邊形形狀的拓撲特徵和幾何特徵，這些特徵在透視投影下是不變的，以這些特徵給出了在透視投影下平面多邊形為類似形的定義。 -
Since the varies of gun attitude angle and the vertical vector of the homograph plane are one - to - one, all the elements of modulation gun can be transformed into the calculation of the vertical vector angle, which avoids the calculation accuracy loss of the traditional approach under the condition of the tiny attitude angle disturbance
由於火炮姿態角變化與相應平面的法向量是一一對應的，從而可將調炮諸元轉化為法向量夾角來計算，這樣可避免傳統方案在微小姿態角擾動情形下導致的計算精度可能的損失。 -
In this thesis, six topological characteristics and geometry characteristics are proposed that are invariant under affine transformations and axonometric projection. the definition of homograph is given based on these characteristics, and then the recognizing method of the homograph is proposed according to the definition of homograph at the same time
其次，根據仿射不變性提出了6個用來描述多邊形形狀的拓撲特徵和幾何特徵，這些特徵在軸測投影下是不變的，以這些特徵為約束條件給出了在軸測投影下類似形的定義。
