Abstract
The invention relates to a sensor device (2) for a motor vehicle (1). The sensor device has a light source (10) and a detection device (20), said detection device being formed using an array of optical pixels. The light source (10) and the detection device (20) are coupled to a control and evaluation device (30) which activates the light source (10) to emit light pulses and the detection device to carry out the detection process. The control and evaluation device (30), the detection device (20) and the light source (10) together act as a time-of-flight camera (ToF camera), allowing spatial range data to be detected. The control and evaluation device (30) is designed to operate the light source and the detection device in at least two modes, i.e. an initialization mode and a measuring mode. The control and evaluation device (30) activates the detection device in the initialization, mode and interrogates all the pixels at least once to obtain signals. Each pixel is classified into a group of relevant pixels or into a group of irrelevant pixels depending on the result of this interrogation. The detection in measuring mode is permanently adapted in such a way that only the signals of t…
