Abstract

The embodiment of the invention discloses a method, device and equipment for determining the static state of an obstacle, and a storage medium. The method comprises the steps: acquiring real-time obstacle speeds, detected by at least two sensors, of the same obstacle; calculating a reliability function assignment values of each sensor under at least two state parameters according to the real-timeobstacle speeds corresponding to the sensors; integrating the reliability function assignment values of all sensors under the state parameters through employing the D-S evidence combination techniqueto obtain the fusion reliability function assignment values corresponding to all state parameters; and judging the static state of the obstacle according to the integrated reliability function assignment value corresponding to all state parameters. According to the technical scheme of the embodiment of the invention, the method can ensure the independence of an algorithm module for determining thestatic state of the obstacle in an unmanned vehicle system and the functional integrity of the entire integrated system, thereby improving the stability, reliability and accuracy of the unmanned vehicle system in determining the static state of the obstacle.

Description

technical field [0001] Embodiments of the present invention relate to data processing technology, and in particular, to a method, device, equipment and storage medium for determining a stationary state of an obstacle. Background technique [0002] In recent years, with the continuous development of sensor technology, control system and artificial intelligence technology, unmanned vehicles (hereinafter referred to as unmanned vehicles) and ground mobile robots have achieved great development. Taking unmanned vehicles as an example, in real dynamic environments, unmanned vehicles need to be able to stably and accurately detect obstacles and identify the movement state types of obstacles in the environment perception, which can play a very important role in establishing a motion model for path planning. With great help, it can assist unmanned vehicles to make various intelligent decision-making behaviors. [0003] At present, in the unmanned vehicle system, judging whether the...
