摘要: 智能车辆道路环境感知中道路目标的准确快速检测,是智能车辆安全辅助驾驶和自动驾驶中的难点。为此,在整体视觉结构模型的基础上,模拟人体由局部到整体的认知机理,并基于原目标局部模型引入结构化信息及概率统计模型,得到更具姿态和尺度适应性的整体视觉结构模型。该模型在弱标注训练样本的基础上可实现目标局部特征区域的自动标注功能,从而获得更具特征描述性的目标特征。实验结果表明,该模型可实现道路典型目标的高检测率和低误码率,且算法效率与经典算法相比有所提高。

Abstract: Fast and correct detection of on-road objects is a difficult problem in the field of assistant driving and automatic driving of intelligent vehicles.So,based on overall visual structure model,the visual cognitive mechanism from the local to the whole is simulated.The structural model is introduced in the object part model,as well as the statistical model,the overall visual structural model with scale invariance and posture invariance is gained.Through weak-labeled sample image,the model can automatically label the representative local areas so that this model can be more discriminable in detection.The new model is adapted to detect obstacle object in road area.Experimental results show that the object detection algorithm based on the proposed model has higher efficiency than traditional algorithms.It has high detection rate and low error rate.
