# LiDAR Object Detection & Tracking

A gallery of labeling and evaluation interfaces built with Label Studio Enterprise programmable interfaces. Each entry is a starting point to adapt, not a fixed template.

Annotate 3D point clouds with cuboids, track objects across frames with keyframe interpolation, and review calibrated camera views, all in one task.

Most perception teams annotate the same scene four times: once for cuboids, again for camera views, again for tracking, and once more for review. This interface keeps all of it in one workspace.

Annotators work the 3D point cloud alongside a top-down view and a camera panel that follows whatever cuboid is selected. Keyframe interpolation carries objects across frames, so adjusting one position updates the frames around it instead of redrawing each one — which is where identity swaps usually creep in. Model predictions load as editable suggestions to accept, adjust, or reject. Validation runs inside the task, so blocking errors surface before completion rather than in a separate audit pass weeks later.

Handles COPC files in the tens of millions of points, with cuboids, points, lines, lanes, and segmentation masks side by side.
