The invention discloses a scene complexity assessment method and system, and the method comprises the following steps: inputting a parameter set used for describing a to-be-assessed scene into a scene complexity assessment model for outputting a scene complexity assessment result, and the construction of the scene complexity assessment model comprises the following steps: selecting a plurality of typical scenes; acquiring a parameter set for describing the typical scene; obtaining driving data corresponding to the typical scene, and obtaining a difficulty label corresponding to the typical scene based on the driving data; and by taking the parameter set of the typical scene as input and the difficulty label of the typical scene as output, constructing a scene complexity evaluation model through an SVM or decision tree algorithm. According to the method, the scene complexity evaluation model is constructed by analyzing the afterward driving characteristics, taking the driving difficulty as the representation form of the scene complexity, taking the difficulty label as the output and taking the scene component as the front item input, so that the measurement of the complex traffic scene is realized.

    本发明公开了一种场景复杂度评估方法及系统,包括以下步骤:将用于描述待评估场景的参数集合输入场景复杂度评估模型,用以输出场景复杂度评估结果,其中,所述场景复杂度评估模型的构建包括以下步骤:选取若干典型场景;获取用于描述所述典型场景的参数集合;获取所述典型场景对应的驾驶数据,基于所述驾驶数据,得到所述典型场景对应的难度标签;以所述典型场景的参数集合为输入,以所述典型场景的难度标签为输出,通过SVM或决策树算法,构建场景复杂度评估模型。本发明通过对事后驾驶特征进行分析,用驾驶难度作为场景复杂度的表现形式,以难度标签为输出,以场景组成要素作为前项输入,构建场景复杂度评估模型,从而对复杂的交通场景实现度量。
