Abstract

A method for simulating a sensor system includes checking whether an intersection of the first image and the second image exists and assessing whether or not the second virtual object is perspectivally occluded. In case an intersection exists, the Euclidean distance between the sensor and the first virtual object is smaller than the Euclidean distance between the sensor and the second virtual objects, and the size of the intersection exceeds a pre-defined threshold value, the second virtual object is assessed as perspectivally occluded. In case an intersection does not exist, the Euclidean distance between the sensor and the first virtual object is not smaller than the Euclidean distance between the sensor and the second virtual objects, or the size of the intersection exceeds a pre-defined threshold value, the second virtual object is assessed as not perspectivally occluded.
