查询词典 symmetric figure

In topographic map, especially for city area, most of features are central symmetry and axial symmetry. By means of extracting features with symmetric figure first and then vectoring them according to their geometric characteristic, accuracy and efficiency can be increased and data sizes can be reduced.

在地形图中，轴对称和中心对称的要素占据着相当大的比例，特别是城市地形图中，房屋建筑等具有对称形状的要素占据了地形图中要素的绝大部分，在扫描图中首先对这些要素进行提取，进而根据特定要素的几何特征矢量化，可显著地提高矢量化精度和效率，减少数据的储存量。

The flywheel has a shape formed by rotation, around the rotation axis, of a geometric figure symmetric about the rotation axis and the axis perpendicular to the rotation axis, and split into two parts (2, 3), e.g. of equal volume, by a plane passing at an angle greater that forty five degrees and smaller than ninety degrees to the rotation axis, the two parts being rotated relative to each other around the rotation axis at an angle no greater than ninety degrees.

所述飞轮具有由相对于旋转轴线和垂直于该旋转轴线的轴线对称的几何图形围绕旋转轴线旋转所形成的形状，并被与旋转轴线成大于45度小于90度角的平面分成两部分(2、3)，例如等体积的两部分，所述的两部分围绕旋转轴线以不大于90度的角度彼此相对于旋转。

Please point out whether the figure is symmetric or asymmetric.

The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map.

前者匹配效率高，稳定性好，对图象的非本质的变化不敏感；而后者利用图象中的所有信息，所以区分不同图象的能力强，精度高，特别是它能在十分复杂的图象环境下(此时很难甚至不可能使用特征匹配法)有效地工作。
