The invention relates to the technical field of target detection, and provides a millimeter wave radar target association method and system based on multi-dimensional similarity. The method comprises the following steps: calculating a deviation distance between detection information and track information according to a target state parameter; calculating the similarity between the target state parameter detection information and the trajectory information based on the probability distribution of the target state parameter on the deviation distance; matching based on the joint similarity of the at least two target state parameters to obtain a target association result; the probability distribution is a piecewise function over the deviation distance. According to the method, the similarity of the target state parameter detection information and the trajectory information is calculated through the segmented probability distribution on the deviation distance, and matching is carried out by combining the joint similarity of at least two target state parameters on the basis, so that on the premise that excessive super parameters are not introduced, the calculation resource demand is smaller, and the matching efficiency is improved. And a more accurate target association result is obtained.
Description
technical field [0001] The present invention relates to the technical field of target detection, in particular to a millimeter-wave radar target association method and system based on multidimensional similarity. Background technique [0002] Autonomous driving, also known as unmanned driving, computer driving or wheeled mobile robot, is a cutting-edge technology that relies on computer and artificial intelligence technology to complete complete, safe and effective driving without human manipulation. [0003] In the 21st century, due to the continuous increase of car users, road traffic congestion, safety accidents and other problems are becoming more and more serious. With the support of Internet of Vehicles technology and artificial intelligence technology, autonomous driving technology can coordinate travel routes and planning time, thereby greatly improving travel efficiency and reducing energy consumption to a certain extent. At the same time, automatic driving can hel...
