Abstract

A method for detecting a parallax problem in sensor data from two sensors, wherein the sensors are spaced apart at different positions and at least partly capture the same environment, and one of the sensors provides distance information items. The method includes receiving the acquired sensor data from the sensors; receiving or estimating sensor visual range information items from the other of the sensors; assigning measured values in the acquired sensor data of the one sensor to measured values corresponding to each of them from the other sensor, the assignment taking into account respective imaging conditions; comparing the distance information items and the received or estimated sensor visual range information items on each of the measured values of the sensor data, wherein a parallax problem is detected in response to a distance exceeding a threshold criterion; and outputting a comparison result.
