Multi-target data association method based on photoelectric sensor

Abstract

The invention discloses a multi-target data association method based on a photoelectric sensor. The multi-target data association method comprises the following steps: judging angle measurement information according to the angle measurement information acquired by different sensors and judging whether the angle measurement information comes from the same target or not; obtaining three-dimensionalspace coordinate information of the target after judging that the three-dimensional space coordinate information comes from the same target; and updating the track of the target based on a nearest neighbor plot-track association algorithm of the weighted sum distance. According to the invention, multi-target tracking can be realized under the condition that only the measurement information of theazimuth angle and the pitch angle of the target can be obtained. The multi-target data association method based on the photoelectric sensor can be widely applied to the field of multi-target trackingand multi-sensor information processing.

Description

technical field [0001] The invention relates to the fields of multi-target tracking and multi-sensor information processing, in particular to a photoelectric sensor-based multi-target data association method. Background technique [0002] In the field of multi-target tracking, data association technology is a key technology to realize multi-target tracking, and how to use measurement information for data association is the core issue. In an increasingly complex modern environment, a single sensor cannot provide comprehensive and accurate air and space situation information. Combined with multi-sensor measurement information, the use of information processing and fusion technology can better grasp the real-time battlefield situation. However, the current single sensor is in Multi-target tracking cannot be achieved if only the target azimuth and elevation angle measurement information can be obtained. Contents of the invention [0003] In order to solve the above technical ...
