Smart helmet for construction site documentation and work support

We present a wearable sensor system which supports construction site workers in work documentation, and access to digital information. In a standard safety helmet self localization (IMU and LIDAR), room dimension estimation (LIDAR) and material detection (ultrasound) have been integrated. A combination of IR cameras retrieves temperature scans of the environment usable for leak detection and isolation checks. The camera, together with a head mounted display also supports a head movement controlled picture-based documentation.
