This paper researches the technique of solid modeling based on ICT slicing images, and reconstructs the solid models. It includes slice sampling, dominant points detection on edge lines, inside and outside boundary recognition based on simple loops, solid modeling, 3D machining features recognition based on 2D drawing features and the relations determination of corresponding drawing feature between successive ICT images. The accuracy of solid modeling has been improved through above methods.\;

本文研究了基于 I C T 切片图象的实体建模技术,重构了产品的实体模型.针对装配体 I C T 切片图象的特点,提出了切片采样,精确识别轮廓控制点的算法,基于简单环的内外边界识别,实体建模,基于二维图形特征和上下切片特征之间的关系识别三维特征,通过以上方法提高了实体建模的精度。

A new approach for rough cutting is presented based on a mesh model generated in terms of the stock shape and rough cutting allowance. There are no restrictions to surface representations and stock shapes. The method is simple and effective. It can recognize contours and islands and seek for drill positions automatically.

提出了一种点阵投影式的粗加工方法。该方法对模具或机械产品的造型没有特殊要求,既可以是规则的实体模型,也可以是自由曲面模型。而且,允许曲面之间有缝隙或相互重叠;毛坯可以是任意形状。该方法计算模型简单,铣削过程中抬刀很少,加工效率高。能自动识别轮廓和岛屿,通过对轮廊和岛屿的合理布局,可方便地实现刀具轨迹的优化和粗加工钻孔点的自动生成。

The recognition method of the harbor target is presented. There are two aspects in the recognition. One is the recognition of the harbor contour, the other is the recognition of the texture of the harbor area on one side of the contour. The chain code of the contour represents the orientation and the curvature of the contour, and the control points are detected by the extrema of the wavelet transform after adaptive smoothing. The primitive of the harbor contour is some structure of successive control points....

The recognition method of the harbor target is presented. There are two aspects in the recognition. One is the recognition of the harbor contour, the other is the recognition of the texture of the harbor area on one side of the contour. The chain code of the contour represents the orientation and the curvature of the contour, and the control points are detected by the extrema of the wavelet transform after adaptive smoothing. The primitive of the harbor contour is some structure of successive control points. The primitive is recognized by three features related to these points, which are scale and rotation invariant.

港口目标的识别包括两个方面 :识别港口轮廓和识别轮廓两侧的港口纹理 .轮廓链码表示轮廓的走向及轮廓曲线的曲率 ,经过自适应平滑后由小波变换的极大值检测得到角点 ,即大曲率点 .港口轮廓的基元是一种连续四个角点的结构 ,基元的识别取决于与这些角点有关的三个特征 ,这些特征只与角点的角度正负性质有关 .
