Title:
CALIBRATION METHOD AND DEVICE FOR MULTI-SENSOR, COMPUTER EQUIPMENT, MEDIUM, AND VEHICLE
Document Type and Number:
Japanese Patent JP2020046427
Kind Code:
A
Abstract:
To solve a problem that calibration accuracy is limited by a sensor calibration method, to realise calibration by data simultaneously collected with a plurality of sensors; and to improve the accuracy of sensor calibration by using multi-source information obtained as much as possible.SOLUTION: A calibration method and device of a multi-sensor, computer equipment, a media, and a vehicle are disclosed. The method includes: a step S110 for respectively obtaining data collected in the same period with at least three sensors during the traveling of a vehicle; a step S120 for deciding respective tracks on the basis of respective data collected with at least three sensors; and a step S130 for aligning the respective tracks of at least three sensors and realising composite calibration of at least three sensors.SELECTED DRAWING: Figure 1
