Abstract

The invention discloses an information fusion method and system of a multi-sensor system, a computer device and a medium. A specific embodiment of the method comprises the steps of dividing a signal time length into a plurality of time windows, and obtaining a target sensor of a current time window; dividing the current time window into at least two sub-windows, judging whether the target sensor has a fault in the current time window or not according to the sum of the observation residual statistical property values of the target sensor at all moments in the current time window and a window preset chi-square distribution threshold; if yes, according to the time sequence of the sub-windows, judging the sub-windows where the faults of the preset chi-square distribution threshold values of the corresponding sub-windows are located sequentially according to the sum values in the sub-windows and the time sequence of the sub-windows, and judging the time when the faults occur moment by moment according to the characteristic values of all the moments in the sub-windows and the time preset chi-square distribution threshold values; and obtaining an information fusion result of the target sensor at the end moment of the current time window according to the fault condition of the target sensor in the current time window.

Description

technical field [0001] The invention relates to the field of sensor information processing. More specifically, it relates to a multi-sensor system information fusion method and system, computer equipment and media. Background technique [0002] AR / VR (Augmented Reality / Virtual Reality, Augmented Reality / Virtual Reality) systems, medical health sensor smart systems, target tracking systems, image and video retrieval systems and other complex systems are all multi-sensor systems, and various multi-sensor systems combine each When the information collected by the sensor is fused, information fusion technology needs to be used to complete it. At present, the information fusion technology of multi-sensor system has become a research hotspot, and the combination of nonlinear state estimation method and information fusion technology of multi-sensor system is getting higher and higher. The information fusion of multi-sensor system can make full use of the effective resources of mu...
