The reconstruction properties of the dilute objects are different from the extended objects. The dilute objects can be reconstructed from a few of projections. In the case of the extended objects, the projection number needed for reconstruct is proportional to the number of resolvable elements. And the projection number cannot be decreased by means of augmenting sampling points in each projection. The depth resolution of the dot coded imaging is discussed as well.

本文论述了离散点集与连续物体的投影重构的不同性质。对于离散点集,只要少数几个投影便能唯一地重构出物体。对于连续物体,投影的必要数目与物体中可分辨的单元数成正比,并且投影上采样的数目与投影数有相互独立的要求。另外,还对点编码图像的纵向分辨能力作了讨论。

This paper investigates the theory of the comprehensive measurement of roundness, cylindricity and mating size by using a commonly-used roundness measuring instrument and digital sampling method. The profile of the cylinder is measured in some sections perpendicular to the table axis. The relatively systematical, accurate and perfect mathematical models are made by some methods such as least squares, least squares-like, minimum .zone methods. The authors have studied the non-smooth extreme problem and then obtained satisfactory results by comprehensively using the line overshoot search and well-known BFGS variable metric algorithms for the mathematical models. The sampling number on a section perpendicular to the table axis and pitch are determined by using sampling technique and the time series analysis theories. The calculation is very efficient because the deleting data technique has been employed.

作用尺寸是评定形状误差和尺寸的一项综合指标。本文利用通用的圆度仪和数字采样方式,采取逐个测量正截面的方法,探讨综合测量外圆柱面圆度、圆柱度误差和作用尺寸的基本理论。由最小二乘、最小外接和最小区域几种评定指标,建立了比较系统、精确和完善的数学模型。使用求解非光滑极值的Overshoot search方法和著名的BFGS变尺度方法进行最优化处理。根据采样技术和时间序列分析的有关理论,确定了正截面上采样点数的合适范围和各截面之间的间距。运用删点技术提高计算效率。通过大量测量和由微机计算,取得了满意的结果。
