Abstract

The invention provides a roadside sensor calibration method and a device, and the method comprises the steps: obtaining the real-time position information of a vehicle and the sensing range information of each roadside unit, and determining the relative position information of the vehicle and each roadside unit according to the real-time position information and the sensing range information; andwhen the relative position information represents that the vehicle runs to the target sensing range of the target roadside unit, obtaining observation data obtained by observing the vehicle-mounted calibration device by the target roadside sensor of the target roadside unit, and finally obtaining a pose calibration result of the target roadside sensor according to the observation data. The vehicle-mounted calibration device is arranged on the vehicle, when the vehicle enters the sensing range of the target roadside unit, the position information and the calibration device required by calibration can be provided for the roadside sensor of the target roadside unit, a large amount of labor cost is saved, and the calibration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a roadside sensor calibration method and device. Background technique [0002] Multi-sensor fusion of roadside units to perceive the environment is an important technology for vehicle-road coordination. To provide effective observations for roadside sensors for vehicle-road coordination, it is first necessary to calibrate the sensors of roadside units. The current roadside sensor calibration method relies on manually adjusting the pose of the calibration device to provide observations for roadside sensors, and then summarizes the observation data for calibration. However, the manual calibration method for a single agent is inefficient in the calibration of roadside units, which cannot meet the rapid deployment of roadside units, and the manual calibration method cannot quickly provide the area of ​​the calibration device. human intervention. [0003] Therefore, the ex...
