该等值线用于确定哪个等值面被提取。
This Isocontour is used to determine which isosurface is extracted.
一旦等值面方程被建立起来，可以设计相应的算法从深度数据中提取等值面，从而实现多视场深度像的融合。
Once such an equation is build up, the algorithm can be designed to extract iso-surface from range data and the consequent application of multi-view range image integration.
