The embodiment of the invention provides a position sorting method and a position sorting device. The position sorting method comprises the following steps: determining an initial sequence of objectsaccording to position interval information; and determining joint probability distribution between the positions of the overlapped objects when an overlapping region exists between the objects in theinitial sorting, determining a local sorting of the overlapped objects according to the joint probability distribution, and finally determining position sorting of each object in the object set according to the initial sorting and the local sorting of the objects. Position interval information of each object in the object set is used, initial sorting is firstly determined, then the joint probability distribution between the positions in the overlapped objects is locally sorted, and the position sorting of all objects in the object set is finally achieved. The influence of random factors on anestimation result of the relative position between the objects in the actual situation is reduced, and the accuracy of the sorting result is improved.
本申请的实施例提供了一种位置排序方法及装置。该位置排序方法包括:根据位置区间信息,确定对象的初始排序;在初始排序中的对象间存在重叠区域时,确定重叠的对象的位置之间的联合概率分布,以根据联合概率分布,确定重叠的对象的局部排序,最后根据对象的初始排序和局部排序确定对象集合中各对象的位置排序。通过基于对象集合中的各个对象的位置区间信息,先确定初始排序,再确定重叠的对象的位置之间的联合概率分布得到局部排序,最后得到对象集合中各对象的位置排序,本申请实施例的技术方案降低实际情况中的随机因素对各对象之间相对位置的估计结果的影响,提高排序结果的准确度。
