Surface approximation uncertainty

本项目P4的主要目标是在考虑目标复杂性的情况下，对模型不确定度（依赖于真实表面）和测量不确定度进行分离和数值量化。此外，为了实现上述主要目标，还应引入一种新的基于分形几何的通用方法。该方法将适用于任何一种提供（无序）点云的基于表面的测量技术。转移到实际应用，包括数值验证应该只基于研究单位相关的TLS实例。在本研究单位内，本研究是P1、P3、P4合作研究的重点。

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.
