摘要： A computer-implemented method for safeguarding a system against false positives. The method includes: receiving a time series of a criticality, the system including a functionality that is triggered when the criticality meets a first predetermined criterion; computing a time series of a reference, the reference being a comparison criticality for a triggering of the functionality; computing a time series of an error measure at least based on the time series of the criticality and the time series of the reference, a triggering of the functionality being classified as a false positive when a portion of the time series of the error measure meets a second predetermined criterion; and identifying at least one near-false positive, a non-triggering of the functionality being classified as a near-false positive when a portion of the time series of the error measure meets a third predetermined criterion, but not the second predetermined criterion.

摘要： A computer-implemented method for safeguarding a system against false negatives. The method includes: receiving a time series of a criticality, the system including a functionality that is triggered when the criticality meets a first predetermined criterion; computing a time series of a reference, the reference being a comparison criticality for triggering the functionality; computing a time series of an error measure based on the time series of the criticality and the time series of the reference, a non-triggering of the functionality being classified as a false negative when a portion of the time series of the error measure meets a second predetermined criterion; and identifying at least one near-false negative, a non-triggering of the functionality of the system being classified as a near-false negative when a portion of the time series of the error measure meets a third predetermined criterion, but not the second predetermined criterion.

摘要： A method for monitoring a vehicle's surrounding region, includes reading in a distance image pertaining to the surrounding region, the distance image including distance values representing the result of a multiplicity of distance measurements, which are performed with a sensor for stereo image recording based on a method for calculating a stereo disparity map concerning the surrounding region sensed by the sensor. In a selecting, a cut-away portion from the distance image is selected, and in a detecting, an obstacle located in the surrounding region is detected using the distance values included in the cut-away portion. In an ascertaining, a number of relevant distance values is ascertained, which represent distance values included in the cut-away portion that are allocatable to the obstacle. In an ascertaining, a value of an existence measure for the existence of the obstacle is determined, based on the number and quality of relevant distance values.
