With the promotion of policies and the continuous development of artificial intelligence, autonomous vehicle have gained more and more attention. The environment perception system is the key to realize the real-time interaction between the vehicle and the external environment. It is also the first step to realize automatic driving, and plays an important role in the safe driving of autonomous vehicle. The development and application of the environmental perception algorithms cannot be separated from testing and evaluation. The test evaluation can effectively verify the accuracy and stability of the environment perception algorithm, and provide reliable input for the decision-making and control of the auto drive system. This article establishes a perception algorithm testing system based on data playback, and proposes a testing and evaluation method for perception algorithms based on the environmental information requirements of decision control systems, in order to improve the development efficiency of environmental perception algorithms.
