The present invention relates to a reliability management-based uncertainty elimination scene perception system and a working method thereof. The system comprises a scene information collection module, a scene information processing module, a knowledge library module, a scene response module, a scene information application module, a scene information retrieval or subscription module, a scene information correction module, and a user feedback module. The scene processing module comprises a multi-algorithm incompleteness elimination unit, an algorithm result inconsistency elimination unit, a credibility management unit, a reliability management unit, an information source inconsistency elimination unit, a scene information fusion deduction unit, and an adaptive management unit. Through adoption of the system and method, more reliable scene information can be obtained, and the accuracy, reliability and self-adaptation of the scene perception system are improved remarkably.
