Abstract

The invention discloses a sensor calibration method, device and equipment. A sensor to be calibrated can be fixed on environment adjusting equipment. Afterwards, through a reference sensor preset in the environment adjusting equipment, a state parameter of the environment adjusting equipment can be obtained as a first state parameter, and whether the environment adjusting equipment is in a vibration state or not is judged according to the first state parameter. When the environment adjusting equipment is not in the vibration state, the sensing data collected by the to-be-calibrated sensor is obtained, the error parameter corresponding to the to-be-calibrated sensor is determined according to the sensing data, and the to-be-calibrated sensor is calibrated according to the error parameter, so that the sensor calibration is accurately performed under the condition of reducing the cost.

Description

technical field [0001] This specification relates to the field of unmanned driving technology, in particular to a sensor calibration method, device and equipment. Background technique [0002] In the field of unmanned driving technology, it is necessary to use a variety of sensors to locate unmanned equipment, such as gyroscopes, lidar, etc. Usually, the sensors themselves have certain errors. Before using sensors to locate unmanned equipment, it is necessary Error calibration of the sensor. [0003] In order to ensure the accuracy of the error calibration of the sensor, it is necessary to prevent the sensor from being affected by external force. Calibrate below. [0004] However, in the prior art, in order to calibrate a static sensor in different environments, it is usually necessary to calibrate the sensor in a large cold storage or a vibration-isolated incubator, but this method is costly. [0005] Therefore, how to reduce the cost and accurately calibrate the sensor ...
