Embodiment Construction

[0082] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0083] Such as figure 1 As shown, a heterogeneous sensor joint track association and tracking method includes the following steps:

[0084] S1. Initialize system parameters; the data initialized in the step S1 includes sensor monitoring range, monitoring range resolution unit, number of sensors, sensor measurement error, sensor scanning period T and total scanning frame number K. In this embodiment, the monitoring range of the sensor is [80x80]km 2 , The resolution unit of the monitoring range is 1m, and the total number of scanning frames is 3000 frames. Three sensors, radar, AIS, and ADSB, are set in the scene. The standard deviation of the measurement error of the radar is 600m, and the data update period is 20s; the standard deviation of the measurement error of the AIS is 100m, and the data update period is 1s; the measurement error of ...

Abstract

The invention discloses a heterogeneous sensor combined track association and tracking method, which comprises the steps of S1, initializing system parameters; S2, mapping a plurality of data sourcesto a unified Cartesian coordinate system through Gauss Kruger projection; S3, performing coarse association on the data source message through hash coding; S4, performing Kalman filtering processing on the message track; S5, performing time alignment on the filtered message trace points through linear extrapolation and interpolation; S6, carrying out trace point association through a nearest neighbor algorithm; and S7, carrying out track association through a (M, C) / N logic judgment criterion. The method has the advantages of low calculation complexity, high association accuracy and the like.

Description

technical field [0001] The invention belongs to the field of sensor fusion tracking, and in particular relates to a track association and tracking method for heterogeneous sensors. Background technique [0002] With the continuous development and progress of digital technology and the advent of the era of Internet of Everything, modern society has higher and higher requirements for digital and intelligent electronic information equipment. As the core unit of all data aggregation and processing in the area, the intelligent control unit needs to provide real-time, accurate and reliable monitoring status results for the monitoring area. The information space perceived by the existing single sensor has a small coverage and a low measurement space dimension, which is difficult to meet the requirements of data processing in the era of the Internet of Everything. The fast-developing sensor network fusion technology utilizes the collaboration among multiple sensors to obtain better...
