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., UWB., UWB.) 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.
