Problems solved by technology

[0007] It can be seen from the above that the data fusion algorithm in the prior art uses the signal-to-noise ratio as the weighted value, but in a complex interference environment, the signal-to-noise ratio of the interference is sometimes higher than the target, so the fusion is performed according to the signal-to-noise ratio as the weighted value.

Abstract

The invention discloses a data fusion method for sensors. The method comprises the following steps: using a visible light sensor and an infrared sensor to obtain a visible light image and an infrared image of a moving target respectively; extracting current moving target positions from the visible light image and the infrared image respectively; using an improved alpha-beta filtering algorithm to perform target trajectory prediction on the moving target, and obtaining a target predicted trajectory; determining a weighted value of an angular deviation output by each sensor according to the absolute positions of the moving target in the visible light image and the infrared image as well as the target predicted trajectory; according to the angle deviation output by the sensor and the corresponding weighted value, determining an output angle deviation after fusion. By using the data fusion method for the sensors, the influence of false target judgment caused by noise interference on a fusion detection result is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of information transmission and processing, in particular to a sensor data fusion method. Background technique [0002] The basic principle of data fusion is to make full use of multiple sensor resources, through the reasonable control and use of these sensors and their observation information, combine the redundant and complementary information of multiple sensors according to certain criteria, so as to obtain the information of the measured data. A consistent interpretation or description of an object. The basic goal of information fusion is to derive more information from the combination of data than from any individual elements present in the input information. This is the result of optimal synergy, i.e. taking advantage of multiple sensors operating together or jointly, increasing the effectiveness of the sensor system. [0003] To solve the fusion problem of multi-sensor tracking information and to e...
