Map metrics toolkit provides a set of metrics to quantitatively evaluate trajectory quality via estimating consistency of the map aggregated from point clouds.

GPS or Motion Capture systems are not always available in perception systems, or their quality is not enough (GPS on small-scale distances) for use as ground truth trajectory. Thus, common full-reference trajectory metrics (APE, RPE, and their modifications) could not be applied to evaluate trajectory quality. When 3D sensing technologies (depth camera, LiDAR) are available on the perception system, one can alternatively assess trajectory quality -- estimate the consistency of the map from registered point clouds via the trajectory.

$ pip install map-metrics

Run metric algorithms from map_metrics on your point cloud data.

from map_metrics.metrics import mme
from map_metrics.config import LidarConfig

result = mme(pointclouds, poses, config=LidarConfig)
