Method, system, and computer program product for determining a blockage of a sensor of a plurality of sensors of an ego vehicle

autonomous-driving
A Bayesian method for detecting sensor blockage in a multi-sensor vehicle: a prior blockage probability is combined with each sensor’s runtime performance to compute a posterior blockage probability used to flag blocked sensors.

Abstract

A method determines a blockage of a sensor of a plurality of sensors of an ego vehicle. The method determines a prior blockage probability of the sensor of the plurality of sensors; receives sensor data of the sensor of the plurality of sensors; determines a performance of the sensor based on the received sensor data; calculates a posterior blockage probability based on the prior blockage probability of the sensor and the performance of the sensor; and determines the blockage of the sensors using the calculated posterior blockage probability.
