| 摘 要： | 针对三焦点曲线进行研究。首先提出一类三焦点曲线的概念和数学表达式，对该类
三焦点曲线表达式的性质进行分析。其次，通过变化三焦点曲线参数，用计算机编程方法对三焦
点曲线进行定量化分析和形状分析，分析和总结得到了曲线性质和规律。最后，通过对实际物体
图像进行处理、提取边缘、曲线拟合等图像处理方法获得物体图像的三焦点曲线表示，并对实验
结果进行了误差分析。实验结果表明三焦点曲线能够精确表示某些自然物体图像的轮廓。

| Abstract: | A kind of trifocal points curve is mainly researched. Firstly, the concept and formula of this
kind of trifocal points curve is presented, and the properties of the trifocal points curve are also
analyzed. Secondly, quantitative and shape analysis is made on the trifocal points curve by turning its
parameters, and the programming method is used to realize the shape analysis of the trifocal points
curve. The properties and rules of the trifocal points curve are analyzed and summarized. Finally, the
parameters of the trifocal points curve are calculated by using of the image processing and fitting
method which is the contours of images of some objects. Moreover, the error analysis is given and the
fitting curve is described. The experiment results show that the trifocal points curve can be the precise
representation of the contours of the images of some natural objects. |
