Abstract: A process and an image evaluation system are provided with a mobile sensor arrangement, including a camera (IR), a motion sensor (IMU), and a receiver (Komm), that is moved through a spatial area. The camera generates an image sequence. The motion sensor generates an orientation signal with camera viewing direction in a predefined three-dimensional coordinate system when generating an image. A signal processing unit (Sv) checks whether the receiver is receiving a signal from a transmitter (UWB.1, UWB.2, UWB.3) of a transmitter group. If the receiver receives a signal, the signal processing unit determines the distance between the transmitter and the receiver. A classifier (Kl) searches for images of humans in images of the image sequence. The signal processing unit decides whether an image of a human shows a person associated with a transmitter of the transmitter group and may generate a trajectory describing the movement of the camera.

Abstract: A gas-measuring system (100) measures and outputs a gas concentration and includes a gas sensor (110), a digitization module (120), a network (130), an analysis unit (140) and an output unit (150). The gas sensor outputs a raw data signal (112). The digitization module processes the raw data signal and outputs a corresponding digital sensor signal (124) via a wireless module (126) to the network. The digital sensor signal includes the processed raw data signal and sensor identification information. The analysis unit reads the digital sensor signal from the network, to determine the gas concentration of the gas to be tested based on the measured raw data indicated by the digital sensor signal, and outputs a corresponding digital concentration signal (142) to the network. The output unit reads the digital concentration signal from the network and provides a corresponding output (154) via an output module (152).
