Abstract

The invention provides an information fusion method and device and a vehicle information obtaining method and device, and the method comprises the steps: obtaining a plurality of pieces of detection information of a target object; calculating trend terms of the plurality of pieces of detection information according to the plurality of pieces of detection information; calculating a residual error of each piece of detection information according to the trend term and each piece of detection information; calculating the optimal weight of each piece of detection information according to the residual error of each piece of detection information; and according to the optimal weight of each piece of detection information, carrying out weighted fusion on each piece of detection information to obtain fusion information. Because the residual error calculated based on the trend term can be used for representing the error of the detection information, the optimal weight of each piece of detectioninformation calculated according to the residual error of each piece of detection information can reflect the accuracy degree of each piece of detection information more truly, so that the fusion information obtained according to the optimal weight of each piece of detection information is more accurate.

Description

technical field [0001] The invention relates to the technical field of information fusion, in particular to an information fusion and vehicle information acquisition method and device. Background technique [0002] In the existing technology, in order to realize the comprehensive analysis of information from multiple different sources, information fusion is usually combined with various collected information, but the current common practice for information fusion is that for different collection methods and different sources The information is fused by setting corresponding weights, and the selection of weights is still artificially set based on experience. This method is highly subjective due to its dependence on experience, and its accuracy and degree of conformity with the actual situation are not It is difficult to judge, and the method of selecting weights based on human experience also has the problem that the operation process is relatively complicated.
