Development of a robotic measuring system for the equivalence analysis of surface materials by using sensor fusion

该研究项目的总体目标是开发一种基于机器人的客观测量系统，用于通过传感器数据融合对聚合物表面和可能的可持续替代品进行等效分析。例如，为了在汽车内饰中扩大可持续材料的使用，必须通过客观的过程确保新的和可持续的材料在其感官价值和客户的质量印象方面被感知和接受为可比较的传统材料。研究表明，人类大脑使用几种感觉，因此是多模态的，以获取比较材料及其质量所需的信息。在感知表面特征的情况下，人类大脑主要使用触觉、光学和听觉感觉模式。以往的研究往往只在触觉模型的基础上描述人类的物质感知。多元模型也包括人类的视觉和听觉感知，迄今为止在研究中只得到偶尔的关注。为了对人类多感官知觉和刺激处理进行更精确的建模，需要将多模态感官印象与多传感器系统的数据相结合。因此，这揭示了如何在技术系统中近似材料的感官价值和质量印象方面的多感官（视觉，听觉，触觉）感知等效的相应研究空白。为了达到预期的研究目标，一方面进行了人体感官研究，记录了多模态感知对等。为了客观描述表面材料，实现了各种描述符，这些描述符是国际上适用于产品表征的描述符。另一方面，实现了一种利用触觉、光学和声学传感器对表面材料进行表征和测试的测量系统。传感器数据融合的原理代表了一种结合几种技术传感器的潜在方法，类似于人类刺激摄取。为了说明替代聚合物的质量，本研究项目侧重于传统聚合物与可能的可回收或可生物降解聚合物的等效性。

The overall objective of the research project is the development of a robot-based, objective measuring system for the equivalence analysis of polymer surfaces and possible sustainable substitutes by means of sensor data fusion.To extend the use of sustainable materials in automotive interiors, for example, it must be ensured by objective processes that new and sustainable materials are perceived and accepted as comparable conventional materials in terms of their sensory value and the quality impression of the customer. Research shows that the human brain uses several senses, thus multimodal, to pick up the information needed for the comparison of materials and their qualities. In the case of the perception of surface features the human brain primarily uses haptical, optical and auditory sensory modalities. Previous studies often describe the material perception of humans only on the basis of haptic models. Multivariate models, which incorporate the optic and auditory perception of humans as well, have received only occasional attention in research so far. For a more precise modeling of human multisensory perception and stimulus processing, a combination of multimodal sensory impressions with the data of a multi-sensor system is necessary.Consequently, this reveals the corresponding research gap of how the multisensory (visual, acoustical, haptical) perceived equivalence in terms of the sensory value and quality impression of materials can be approximated in a technical system. In order to achieve the intended research goal, on the one hand sensory human studies are carried out to record the multimodal perceived equivalence. For the objective description of the surface materials various descriptors are implemented, which are internationally applicable descriptions for product characterizations. On the other hand, a measuring system for the characterization and testing of surface materials by means of haptic, optical and acoustic sensors is realized. The principles of sensor data fusion represent a potential approach to combine several technical sensors , in analogy to human stimulus uptake. To illustrate the quality of alternative polymers, this research project focuses on the equivalence of conventional polymers with possible recycled or biodegradable polymers.
