Problems solved by technology

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 when only target azimuth and elevation angle measurement information can be obtained

specific Embodiment

[0125] The present invention provides another specific embodiment: a photoelectric sensor-based multi-target data association system:

[0126] An acquisition module, configured to acquire angle measurement information of the target through different sensors;

[0127] A judging module, configured to judge whether the angle measurement information obtained by different sensors comes from the same target;

[0128] The actual point trace module is used to determine that the angle measurement information from different sensors at the current moment comes from the same target, and obtain the three-dimensional space coordinate information of the target according to the angle measurement information;

[0129] The track module is used to obtain the predicted position information of the target at the current moment according to the state of the target at the previous moment, and make a judgment in combination with the actual point track information obtained according to the three-dimens...

Abstract

The invention discloses a multi-target data association method based on a photoelectric sensor, which includes: judging the angle measurement information obtained by different sensors and judging whether the angle measurement information comes from the same target; The three-dimensional space coordinate information of the target; the weighted and distance-based nearest neighbor track-track association algorithm updates the track of the target. By using the present invention, multi-target tracking can be realized under the condition that only target azimuth angle and elevation angle measurement information can be obtained. As a photoelectric sensor-based multi-target data association method, the invention can be widely used in the fields of multi-target tracking and 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 ...
