Algorithms

Check data

Check that obstacle_collision_checker receives no ground pointcloud, predicted_trajectory, reference trajectory, and current velocity data.

Diagnostic update

If any collision is found on predicted path, this module sets ERROR level as diagnostic status else sets OK.

Inputs / Outputs

Parameters

Assumptions / Known limits

To perform proper collision check, it is necessary to get probably predicted trajectory and obstacle pointclouds without noise.
