METHOD FOR ASSESSING THE MEASURING ACCURACY OF A SENSOR DESIGNED TO MEASURE THE DISTANCE ON AN OFF-LINE MOBILE SYSTEM

摘要

The invention discloses an evaluation method for the quality of measuring sensors of an autonomous mobile system. To this end, the plurality of sensors per cell that have surveyed this cell when surveying obstacles for producing a cellularly structured environment map are stored and it is identifiably indicated thereto which sensors have classified this cell in which way. For example, a occupied probability and a free probability is [sic] employed for the classification. The measuring quality is determined with reference to the results that the individual sensors have supplied or the respective cell. The extent to which the classifications of the individual sensors confirm one another is evaluated thereto. Sensors whose measured results deviate from a great number of other sensors are classified as faulty. In order to prevent dynamic objects in the environment from falsifying the quality statement, the system can implement a self-test in that it turns around its own axis within a static but not necessarily known environment and subsequently undertakes the evaluation of the sensors.
