Accountabilities
Create accurate 3D bounding boxes around vehicles, pedestrians, cyclists, static structures, and other relevant objects across LiDAR frame sequences.
Perform detailed 3D semantic segmentation by labeling individual points within dense point clouds while avoiding gaps, overlaps, and inaccurate classifications.
Review and refine AI-generated 3D annotations to ensure they meet established spatial accuracy and quality standards.
Conduct multi-sensor quality assurance by validating LiDAR annotations against 2D camera feeds and checking sensor-fusion alignment.
Track dynamic objects consistently across multiple LiDAR frames, maintaining accurate pitch, roll, yaw, and heading information.
Apply strict cuboid boundary, point-density, occlusion, and spatial annotation guidelines throughout production workflows.
Maintain a minimum target accuracy of 95% while balancing pr
