  • Publication number: 20230408656
    Abstract: Object detection for ranging sensor data may detect objects which are not actually present in the environment. To identify certain of these phantom objects, objects detected in the environment are analyzed to determine whether they are enclosed by another object and if the enclosed object has a distance from the ranging sensor higher than the enclosing object. This may suggest that the enclosing object has a surface or other feature that is sensed as additional depth that manifests as a separate detectable object. These phantom objects are identified and removed from further perception processing.
