Main Research Topics
Machine Vision is a multifaceted discipline and includes aspects from optics (e.g. illumination, lenses), electrical engineering (e.g. sensor technology), mechanical engineering (e.g. industrial robots, optical inspection machines), computer science and software engineering (e.g. efficient implementations of innovative computer vision algorithms). This is also reflected in the research topics:
- Reliable detection and accurate position measurement of objects in images and 3D sensor data
- Camera models and calibration
- Machine learning in industrial applications for object inspection and robotics
- Object identification in images
- Surface inspection of objects in 2D and 3D sensor data
- Hand-eye calibration of industrial robots
Our research work often focuses on geodetic aspects such as reliability or accuracy. At the same time, 20 years of industrial experience serves as an important guide and ensures the innovative power of the newly developed processes.
Teaching
Teaching about methods and technologies that are actually used in practice in the professional field is important to provide a sound insight into machine vision metrology. Only in close exchange with the professional field can the requirements of the technologies be sufficiently considered and the students be taught appropriate skills. These requirements are therefore already imparted in the teaching and should play a fundamental and at the same time motivating role. The industrial context is also emphasized by exercises that are relevant in real applications.
The references of machine vision metrology to "classical" geodesy are emphasized and geodetic aspects (e.g. accuracy considerations and reliability statements) are explicitly considered. Within the framework of research-oriented teaching, students are involved in current research projects at the institute, which also allows scientific methods to be taught.
