Abstract
A computer-implemented method of modelling a perception system for perceiving objects captured in sensor data comprises: receiving a plurality of training examples, each comprising a ground truth scene for a set of sensor data and a corresponding perceived scene obtained by applying the perception system to the set of sensor data; fitting to the training examples noise model parameters, encoding a noise distribution over perceived scenes given a misdetection scene, and misdetection model parameters, encoding a misdetection distribution over misdetection scenes given a ground truth scene; computing a perception distribution over perceived scenes for a given ground truth scene by marginalizing the product of noise and misdetection distributions over multiple misdetection scenes, wherein individual objects in the ground truth scene are not associated with individual objects in the perceived scenes; fitting the noise and misdetection model parameters to match the perception distribution to the perceived scene for each training example.
