Abstract

The invention discloses a sensor scheme determination method, device and equipment and a storage medium, and the method comprises the steps: building a simulation unmanned vehicle and a simulation scene, and enabling the simulation scene to be used for the simulation unmanned vehicle to carry out the simulation driving; determining a first sensor scheme according to the initialization parameters,and determining simulation data generated by simulation driving of the simulation unmanned vehicle in the simulation scene according to the first sensor scheme; and determining a first sensing parameter of the first sensor scheme according to the simulation data, and correcting the first sensor scheme according to the first sensing parameter to obtain a sensor scheme applied to the unmanned vehicle. According to the method, the physical parameters of the sensor, the obstacle form and motion characteristics, the vehicle model size and appearance of the unmanned vehicle and the traffic environment of vehicle driving are fully considered and combined, the determined sensor scheme applied to the unmanned vehicle is high in sensing capacity and high in sensing precision, and safe operation of the unmanned vehicle can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of unmanned vehicles, in particular to a method, device, equipment and storage medium for determining a sensor solution. Background technique [0002] With the rapid development of unmanned vehicle technology, unmanned vehicles have been widely promoted and applied. During the automatic driving process of the unmanned vehicle, the sensors installed on the unmanned vehicle are used to collect sensor data. The unmanned vehicle system formulates the automatic driving plan of the unmanned vehicle and analyzes the automatic driving situation of the unmanned vehicle based on the collected sensor data. Therefore, the perception ability of the sensors installed on the unmanned vehicle is an important factor affecting the safe driving of the unmanned vehicle . [0003] In related technologies, according to the physical parameters of the sensor, the sensor data corresponding to obstacles of different sizes...
