Based on the study of the AIS (Automatic Identification System) and the video of the inland river in the target identification and tracking, this paper presents an algorithm for automatic identification of ships. The AIS data and video data are fused by Kalman filtering algorithm. We can get the optimal value of ship trajectory, improve the reliability and accuracy of the Inland Waterway Navigation.
Bus passenger flow data are the basis of traffic planning department and public transportation operation department for management, operation and dispatching. It has an important significance for traffic flow accurately and predicting traffic flow. But the traditional methods obtaining passenger flow only can get little information by field investigation which are not comprehensive. This paper utilizes...
Micro-motion feature is widely applied in ballistic missile target identification, as an important method. So, on the basis of time-frequency analysis of micro-motion characteristics, identification method based on PZM (pseudo-zernike invariant moment) is proposed in the article. It mainly extracts PZM of frequency image as identification feature. Firstly, one-dimensional time-domain echo signal is...
