The invention relates to a target state estimation method. The method comprises the following steps: acquiring a data frame sequence corresponding to a plurality of moments; determining a first time window in the data frame sequence, wherein the first time window comprises a group of first state quantity sets to be optimized; a plurality of second time windows are determined from the first time window, the number of data frames in the second time windows is smaller than the number of data frames in the first time window, two adjacent second time windows have repeated data frames, and each second time window has a group of second state quantity sets to be optimized; and optimizing the second state quantity sets in the plurality of second time windows at the same time to obtain an optimized first state quantity set. According to the target state estimation method disclosed by the invention, enough accurate state estimation can be obtained. In addition, the invention also provides a target state estimation device, electronic equipment and a medium.
本公开涉及一种目标状态估计方法,包括:获取对应于多个时刻的数据帧序列;在数据帧序列中确定第一时间窗口,第一时间窗口包括一组待优化的第一状态量集合;从第一时间窗口内确定多个第二时间窗口,第二时间窗口内的数据帧数小于第一时间窗口内的数据帧数,相邻两个第二时间窗口具有重复的数据帧,且每个第二时间窗口具有一组待优化的第二状态量集合;通过同时对多个第二时间窗口内的第二状态量集合进行优化,得到优化后的第一状态量集合。本公开的目标状态估计方法能够得到足够精确的状态估计。此外,一种目标状态估计装置、电子设备和介质亦被提出。
