The invention discloses a traffic object behavior prediction method and device, equipment and a storage medium. The method comprises the following steps: selecting a target traffic object, taking the target traffic object as a center, selecting a plurality of points in a first preset range as sensing points, aiming at a reference traffic object in a second preset range of the target traffic object, taking the reference traffic object as a field source of a directed distance field, and calculating the distance and gradient value of each sensing point in the directed distance field; converting the distance and gradient value of the sensing point in the directed distance field into influence factors of the reference traffic objects on the behavior influence of the target traffic object, and determining the interaction characteristics of the target traffic object and all the reference traffic objects based on the influence factors of all the reference traffic objects on the target traffic object, the behavior of the target traffic object is predicted based on the interaction characteristics, the prediction accuracy can be improved, and the interaction prediction capability with high generalization can be learned.
本发明公开了一种交通对象行为预测方法、装置、设备及存储介质。选定目标交通对象,并以目标交通对象为中心,选取第一预设范围内的若干点作为感知点,针对目标交通对象第二预设范围内的参考交通对象,以参考交通对象为有向距离场的场源,计算每一感知点在有向距离场中的距离和梯度值,将感知点在有向距离场中的距离和梯度值转换为参考交通对象对目标交通对象的行为影响的影响因子,基于所有参考交通对象对目标交通对象的影响因子,确定目标交通对象与所有参考交通对象的交互特征,基于交互特征预测目标交通对象的行为,能够提高预测准确度,并学习到具有高泛化性的交互预测能力。
