本文首先回顾了从稠密梯度场计算高度图的积分技术。有几个局部积分方法的建议（科尔曼/Jain 1982，Healey/Jain 1984，Wu/Li 1988，Rodehorst 1993），和两个全局优化的建议（Horn/布鲁克斯1986和Frankot/ Chellappa 1988）。本文讨论了这种集成技术的几个实验评估。所研究的算法在弯曲的物体上得到了高标记，但在多面体形状上得到了低标记。局部自适应的方法，建议科普复杂的形状。
The paper starts with a review of integration techniques for calculating height maps from dense gradient fields. There exist a few proposals of local integration methods (Coleman/Jain 1982, Healey/Jain 1984, Wu/Li 1988, Rodehorst 1993), and two proposals for global optimization (Horn/Brooks 1986 and Frankot/ Chellappa 1988). Several experimental evaluations of such integration techniques are discussed in this paper. The examined algorithms received high markings on curved objects but low markings on polyhedral shapes. Locally adaptive approaches are suggested to cope with complex shapes in general.
