Abstract

The embodiment of the invention provides a motion state estimation method and device, and the method comprises the steps: obtaining a plurality of measurement data through a first sensor, wherein eachmeasurement data at least comprises speed measurement information; and according to the measurement data corresponding to the target reference object in the plurality of measurement data, obtaining amotion state of the first sensor, the motion state at least comprising a speed vector of the first sensor. By adopting the embodiment of the invention, the more accurate motion state of the first sensor can be obtained.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for estimating the motion state of a sensor. Background technique [0002] In the advanced driving assistant system (Advanced Driving Assistant System, ADAS) or automatic driving (Autonomous driving, AD) system is usually equipped with a variety of sensors, such as radar (Radar) sensors, ultrasonic sensors, vision sensors, etc., to perceive the surrounding environment and target information. Using the information obtained by the above sensors, the functions of classification, identification and tracking of the surrounding environment and objects can be realized. Further, the above information can be used to realize the situation assessment of the surrounding environment and planning control. For example, the track information of the tracking target can be used as a vehicle The input of planning control improves the efficiency and safety of vehicl...
