Abstract

The invention provides an information processing and target association method. The method comprises steps as follows: step 1, self-adaptive selection of association gates is performed according to messages sent by different sensors, and the selected association gates comprise an oval association gate, an annular association gate and a truncated fan-shaped association gate; step 2, after the association gates are selected according to the content of the messages, measurement values of a plurality of sensors in effective areas of the association gates are selected, and a selection strategy is to realize self-adaption of an association algorithm according to the number of known targets. According to the target association method, self-adaptive selection of the association gates is performed according to the messages sent by different sensors, and the self-adaption of the association algorithm is performed according to the number of the known targets, so that the de-weight rate of the messages is increased, the mistaken association rate is reduced, and the target fusion accuracy on the multisource and multi-target background is improved.

Description

technical field [0001] The invention relates to the field of data processing, especially the fusion of target motion data information, especially the design of target recognition and target motion prediction models in the case of multi-sensors, and specifically relates to an information processing target association method. Background technique [0002] Object association is one of the core technologies in the field of data fusion, and there are many related studies, and its breakthrough began in the 1970s. In 1971, R.A.Singer and R.G.Sea proposed the nearest neighbor algorithm, thinking that among all the measurements at a certain moment, the measurement closest to the predicted position of the tracked target should be used as the real measurement of the target, and predict the target at the next moment. predicted location. In fact, the real measurement of the target may not be the closest to the predicted position of the target. Therefore, the nearest neighbor method may ...
