The main objective of this project P4 is the separation and numerical quantification of the model uncertainty (dependent on a real surface) together with the measurement uncertainty under consideration of the object complexity. Additionally, a new general methodological approach based on fractal geometry should be introduced for the above-mentioned main objectives. The approach will be applicable to any kind of surface-based measurement technique that delivers (unordered) point clouds. The transfer to practical applications, including a numerical validation should be only done based on the research unit relevant example of TLS. Within this research unit, this study is a key point of research in collaboration between P1, P3 and P4.

该项目P4的主要目标是在考虑对象复杂性的情况下，将模型不确定性（取决于真实的表面）与测量不确定性分离并进行数值量化。此外，为实现上述主要目标，应采用一种基于分形几何学的新的一般方法。该方法将适用于任何类型的基于表面的测量技术，提供（无序）点云。转移到实际应用中，包括数值验证，应仅基于TLS的研究单位相关示例进行。在本研究单元内，本研究是小一、小三、小四合作研究的重点。
