The present disclosure provides systems and methods for generating a multi-dimensional surface model of a geometric structure. The system includes a device including at least one sensor configured to collect a set of location data points corresponding to respective locations on or enclosed by a surface of the geometric structure, and a computer-based model construction system coupled to the device. The computer-based model construction system is configured to generate a working volume based on the set of location data points, calculate a dilated field for the working volume, define a dilated surface based on the dilated field, calculate an eroded field for the working volume based on the dilated surface, and define an eroded surface based on the eroded field. 本发明提供用于生成几何结构的多维表面模型的系统和方法。系统包括装置和耦合至装置的基于计算机的模型构造系统，装置包括至少个传感器，该传感器被配置为采集与几何结构的表面上或由几何结构的表面包围的各个位置相对应的位置数据点的集合。该基于计算机的模型构造系统被配置为基于位置数据点的集合来生成工作体积，计算针对工作体积的扩张场，基于扩张场来限定扩张表面，基于扩张表面来计算针对工作体积的侵蚀场，以及基于侵蚀场来限定侵蚀表面。
