Multi-object tracking method and device driven by characteristic trace

Abstract

The invention provides a multi-object tracking method and a device driven by a characteristic trace. A device observing data module converts a physical property and a motion property of the object into data of a spectrum, a space and a time domain; a characteristic trace generating, managing, confirming and deleting module is used for forming the characteristic trace, managing, confirming and deleting the characteristic trace, and finally outputting characteristic trace information; a tracking door forming module is used for receiving the characteristic trace data and generating and outputting the data of the adjacent domains by defining adjacent domains by the characteristic trace; a filtering module is used for receiving the characteristic trace data of the characteristic trace generating, managing, confirming and deleting module, and predicting the state and position of an output object. The method provides the characteristic trace based on the physical basis of the multi-object detection and tracking, gives the physical property and the motion property of using the object in the spectrum, the space and the time domain, fuses the measuring data to generate the characteristic trace, and uses the Markov confidence of the characteristic trace to realize the multi-object tracking method with high-precision.

Description

[0001] technology neighborhood [0002] The invention belongs to the technical field of multi-target tracking, and relates to a multi-target tracking method and device driven by characteristic traces. Background technique [0003] Detecting and tracking a large number of dynamic targets in the case of strong interference has important applications in national defense and national economy, and is also a major problem in scientific research. The current multi-object tracking methods in the traditional object tracking neighborhood and video tracking neighborhood have their own advantages and limitations, but both have reached the bottleneck for further performance improvement. [0004] Multi-target tracking has a very wide range of applications both in military and civilian applications. Such as detection and tracking of a large number of highly maneuverable incoming aircraft in a large interference environment, monitoring of various traffic vehicles and personnel, etc. The dif...

Problems solved by technology

At this time, there are still problems: there may be multiple observations in the gate, which one is the most likely? At this time, there are also cases where the observations generated by the target are not detected

However, the dynamic characteristics of the target greatly challenge the current generation method of the tracking gate. In the case of insufficient prior knowledge or insufficient use of the target, the optimization is difficult to work
