Labeling Experience

Sama

Data Annotation Associate

Sama3D SensorCuboid
As a Data Annotation Associate at Sama, I performed LiDAR point cloud annotation for autonomous driving perception models. I created precise 3D bounding boxes for vehicles, pedestrians, and cyclists. I also conducted semantic segmentation on 3D sensor data to improve object detection accuracy. • Worked with multi-sensor fusion data including LiDAR, camera, and radar. • Participated in QA review and corrected annotation inconsistencies. • Exceeded productivity targets while maintaining high quality. • Collaborated with client teams to ensure annotation quality.

CVAT

3D Point Cloud Annotation Practice Project

CVAT3D SensorCuboid
In a personal 3D Point Cloud Annotation Practice Project, I utilized CVAT to annotate public KITTI dataset LiDAR point clouds. I created 3D bounding boxes for vehicles, pedestrians, and cyclists across 200+ frames. I implemented quality checks to ensure consistency in occlusion handling and dimension accuracy. • Focused on 3D perception tasks for autonomous vehicles. • Handled annotation for challenging occlusion scenarios. • Developed skills in CVAT annotation tool usage. • Practiced high standards of data consistency and accuracy.
