Problems solved by technology

For example, targets such as trucks, artillery vehicles, and armored vehicles can generally only travel on roads and flat ground, while tanks, infantry combat vehicles, etc. can move on rough terrain, but are still limited by certain terrain conditions such as ravines and cliffs

Abstract

The invention relates to a variable-structure multi-model target tracking algorithm based on a road information base and target road constraint characteristics. A road information base is constructed,the constraint ability of a road network-based road geographic environment and the adaptive ability of different types of targets to different road geographic environments are used as priori information to assist ground target tracking, the state estimation accuracy of ground target tracking is improved through full utilization of priori knowledge, and the target tracking loss rate is reduced. The method has practical value in the aspect of ground target tracking problems.

Description

technical field [0001] The invention belongs to the technical field of target tracking, and in particular relates to a variable structure multi-model target tracking algorithm based on road information database and target road constraint characteristics. Background technique [0002] For ground targets, most ground targets are constrained by roads or geographic environments, and their movements are often predictable, and these roads and geographic information can usually be obtained in advance, and these priors are used when estimating the target state Information, to a certain extent, can improve the accuracy of target state estimation and simplify the computational complexity of the tracking processor. The variable structure multi-model algorithm is an idea that uses prior information to assist ground target tracking. A subset of the models matched to the true motion state is tracked and filtered. Based on road-assisted variable structure interactive multi-model (VS-IMM)...
