Abstract
本申请提供一种目标相似度计算方法、设备、存储介质及程序产品，方法包括：获取待关联的检测目标与跟踪轨迹的状态信息，状态信息至少包括检测目标与跟踪轨迹对应的位置信息以及表征跟踪轨迹运动趋势的运动特征信息；基于运动特征信息确定跟踪轨迹对应的参考运动方向；基于位置信息和参考运动方向对检测目标与跟踪轨迹之间的相对位移进行分解，得到第一位移分量和第二位移分量，第一位移分量沿参考运动方向，第二位移分量垂直于参考运动方向；基于第一位移分量和第二位移分量，得到检测目标与跟踪轨迹之间的相似度距离。本申请显著降低了横向误匹配概率，保持对真实运动轨迹的一致性约束，提升了多目标跟踪过程中数据关联的准确性与鲁棒性。
