Document Type and Number:
Japanese Patent JP2021117043
Kind Code:
A
Abstract:
To correct a shift between three-dimensional point cloud data.SOLUTION: A data acquisition unit 101 acquires first measured data that includes a first vehicle traveling trajectory which is the traveling trajectory of a first vehicle and first three-dimensional point cloud data generated by traveling of the first vehicle and second measured data that includes a second vehicle traveling trajectory which is the traveling trajectory of a second vehicle and second three-dimensional point cloud data generated by traveling of the second vehicle. A feature object association unit 103 associates a first feature object which is a feature object included in the first three-dimensional point cloud data with a second feature object which is a feature object corresponding to the first feature object and included in the second three-dimensional point cloud data as a feature object pair and generates a feature object pair from the first and second three-dimensional point cloud data. A shift amount calculation unit 104 calculates a shift amount between the feature object pairs. A traveling trajectory correction unit 105 corrects the traveling trajectory of the second vehicle on the basis of the shift amount and the second measured data. A point cloud data correction unit 106 corrects the second three-dimensional point cloud data on the basis of the second vehicle traveling trajectory after correction.SELECTED DRAWING: Figure 1
