Abstract

The invention relates to a laser radar calibration method and device, equipment and a storage medium. A terminal, in a preset calibration scene, obtains a point cloud data frame pair of a to-be-calibrated laser radar; inertial navigation system data is obtained; and then through a calibration algorithm, a calibration result of the to-be-calibrated laser radar is determined according to the point cloud data frame pair and the inertial navigation system data. The calibration result of the to-be-calibrated laser radar can be automatically determined, so that the process of obtaining the calibration result of the laser radar by manual measurement is avoided, and the calibration efficiency of the laser radar is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a laser radar calibration method, device, equipment and storage medium. Background technique [0002] With the development of unmanned driving technology, on-board sensors are often used to obtain location information around the vehicle, and then plan, make decisions, or control autonomous vehicles based on the information detected by the sensors. [0003] Typically, in-vehicle sensors use multiple sensors to obtain location information around the vehicle. However, there are certain differences between the relative poses (including relative positions and orientations) of multiple sensors. It is necessary to calibrate the relative poses of multiple sensors so that the location information around the vehicle collected by multiple sensors is unified. To the same coordinate system, and then according to the position information in the same coordinate system, plan, make dec...
