Get in Touch
Datatang provides the highest fully managed workforce throughout the entire data pipeline. Our skilled data analysts apply best practices developed from annotating millions of images and videos to deliver best-in-class data labeling for autonomous vehicle companies across the world.
Featured Annotation Services

Traffic Sign Labeling

Our AI-Assisted Data Annotation platform can easily finish such tasks with around over 98% accuracy

Panoptic Segmentation

Panoptic segmentation is an image segmentation task that combines the prediction from both instance and semantic segmentation into a general unified output

3D Point Cloud Object Labeling

Our tool providers empower our users to annotate objects with 9 degrees of freedom in three dimensions in both 3D scenes and projected side views (top, side, and back)

3D Point Cloud Object Tracking

When our user draws a cuboid around an object, that cuboid will be given a unique ID. Our annotation platform will automatically search for similar objects in other frames

3D Point Cloud Segmentation

3D point cloud segmentation is the process of classifying point clouds into multiple homogeneous regions, the points in the same region will have the same properties. The segmentation is challenging because of high redundancy, uneven sampling density, and lack explicit structure of point cloud data
Data Annotation Advantage
We developed our data annotation platform, which featured AI-assisted automatic object sizing, grounding, colouring, pre-labelling, improved object tracking, etc., which can significantly increase annotation efficacy by 30%

Automatic Object Sizing

Using pre-defined parameters, quickly generate missing object coordinates.

Automatic Grounding

Fast alignment of detected 3D object with identified ground, increasing annotation efficiency.

Automatic Coloring

Automatically generate the ground 3D coordinates through improved planarian algorithm to reduce the miss-labeling ratio, object are colored by distance to the ground

Interpolation Algorithm Intergrated

Automatic Detect Object in a Sequence, annotator only needs to label a few frames, increased productivity

Automatic Object Rotatation

L-shape-filting algorithm implemented to auto rotate object and approximate object size

Advanced Objects Tracking

We created our own object detection algorithm called "Static object tracking," which significantly reduces error and miss matches for Object ID.

Muti-Views annotation Synchronization

All annotation operations in different views are synchronized, and all operations are rendered in read time.
