IPS is a multi-sensor concept for real-time self-location and 3D mapping in unknown environments
IPS is a multi-sensor concept for real-time self-location and 3D mapping in unknown indoor and outdoor environments where external location infrastructure such as GNSS or Wi-Fi are unavailable or restricted.
The model for IPS is the human sense of orientation. Visual and balance senses are replicated using a stereo camera and an Inertial Measurement Unit (IMU), and the sensor data are combined. The process is extremely robust in the face of interference and thus provides reliable information about position and location in space in real time. The computed depth maps created using the IPS stereo camera data are used to generate spatially referenced point clouds of almost any size, which can serve as the basis for subsequent 3D modelling.
Other sensors (for example an HD camera) can be integrated as required. Their data are spatially and temporally referenced by IPS. This is very useful for a wide variety of visual inspection and documentation tasks. IPS is constantly being developed to optimise its functionality and performance. The Institute is conducting research and development work for this purpose in cooperation with industrial partners. The current mobile handheld unit is small, light and ideal for areas that are difficult to access.
