Large amounts of geographical and property rights information are contained in 3D cadastral property units, although the amount of cadastral information expressed from various perspectives varies. Therefore, it is crucial to choose a perspective that is compatible with human visual perception and conveys the most data as the perspective changes. This paper proposes an optimization method for generating the optimal view of 3D cadastral property units to address the above issues. The construction of candidate perspectives is the first step, followed by the calculation of feature values, including visibility of 3D boundary points under each candidate perspective, visible area ratio, and visual comfort. Then, an improved particle swarm optimization technique is used to determine the optimal view of 3D cadastral property units and the ideal viewpoint for the expected input model. The research results show that the selected optimal viewpoint fully considers human visual comfort, can accommodate a large amount of cadastral information, and can be used as a mapping drawing in social applications of 3D cadastral systems. This viewpoint can effectively supplement front views, side views, and axis side views, enabling more visual information to be transmitted in 3D religion maps and 3D property right maps and improving readability.

3D地籍产权单元中包含了大量的地理和产权信息，尽管从不同角度表达的地籍信息量有所不同。因此，选择与人类视觉感知兼容并随着视角变化传递最多数据的视角至关重要。本文提出了一种生成3D地籍产权单元最佳视图的优化方法来解决上述问题。第一步是构建候选视角，然后计算特征值，包括每个候选视角下3D边界点的可见性、可见面积比例和视觉舒适度。然后，使用改进的粒子群优化技术来确定 3D 地籍属性单元的最佳视图以及预期输入模型的理想视点。研究结果表明，选取的最佳视点充分考虑了人类视觉舒适度，能够容纳大量地籍信息，可以作为3D地籍系统社会应用中的制图绘图。该视点可以有效补充正视图、侧视图、轴线侧视图，使得3D宗教地图和3D产权地图能够传递更多的视觉信息，提高可读性。并可用作 3D 地籍系统社会应用中的地图绘制。该视点可以有效补充正视图、侧视图、轴线侧视图，使得3D宗教地图和3D产权地图能够传递更多的视觉信息，提高可读性。并可用作 3D 地籍系统社会应用中的地图绘制。该视点可以有效补充正视图、侧视图、轴线侧视图，使得3D宗教地图和3D产权地图能够传递更多的视觉信息，提高可读性。
