Embodiment Construction
[0045] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0046] Taking a four-wheeled vehicle for SLAM tasks as an example, the following prerequisites are set: the vehicle pose vector X v =[x v ,y v ,θv ]′, feature point position vector X m =[x m1 ,y m1 ,...,x mn ,y mn ]'. Among them, (x v ,y v ) is the coordinates of the vehicle in the world coordinate system, θ v is the angle between the longitudinal axis of the vehicle and the positive direction of the x-axis of the world coordinate system (that is, the yaw angle), (x mi ,y mi ) is the coordinate of feature point i in the world coordinate system. During the running of the vehicle, the vehicle is controlled to move towards the next waypoint by the speed comma...
