Target tracking method and device, equipment and storage medium

The invention discloses a target tracking method and device, equipment and a storage medium. The method comprises the following steps of: assuming an incidence relation between filtering processing data of a target tracking object and a historical track for multiple times; determining first filtering processing data and/or second filtering processing data according to a hypothesis result of the hypothesis; if the first filtering processing data exists, determining an association probability according to the first distance and the first filtering processing data, and if the second filtering processing data exists, determining a new track existence probability according to the second filtering processing data and the second distance; and determining an optimal hypothesis according to at least one of the historical hypothesis association weight, the new trajectory existence probability and the association probability, and determining target tracking trajectory information according to the optimal hypothesis.
