Kalman filtering variance parameter adjustment method, system and device, medium and product

The invention relates to the technical field of information, and particularly provides a Kalman filtering variance parameter adjustment method, system and device, a medium and a product. The Kalman filtering variance parameter adjustment method comprises the following steps: acquiring original sensing data of a radar and original sensing data of a camera; obtaining a first variance sequence based on the original sensing data of the radar and the original sensing data of the camera; replacing the noise variance of the camera and the radar in the Kalman filtering equation based on the first variance sequence, and obtaining the original sensing data of the radar and the original sensing data of the camera in the second fusion process; acquiring a second variance sequence based on the original sensing data of the radar, the original sensing data of the camera and the first variance sequence in the second fusion process; and replacing the first variance sequence in the Kalman filtering equation with the second var
