Abstract
A method for monitoring a spatial environment of a mobile device is provided. During the movement of the device along a predefined path, a three-dimensional spatial region of the spatial environment is captured by a detection device. A three-dimensional environment model is created and/or updated from the captured spatial region at cyclical intervals and is specified by spatial volumes in the spatial region occupied by objects. Actions of the device for preventing a collision with the objects and a risk of collision are determined. One of the actions is then performed if the risk of collision exceeds a predefined value. The method has the advantage that actions for collision avoidance are calculated preemptively at cyclical intervals, so that one of the actions can be performed with a short latency period in an impending collision, that is if the risk of collision exceeds the predefined value.
