Why choose datatang?

Datatang's vehicles with advanced sensors assist in collecting high-quality training data for autonomous driving models.
Datatang AI's annotation platform efficiently handles diverse tasks with human-in-the-loop tools and quality control functions.
Datatang AI annotates thousands of frames a week for detection, tracking, and segmentation across three factories.

Tailored intelligent in-cabin and autonomous driving service

Datatang's data annotation platform supports annotation of RGB, point cloud and voice data for intelligent in-cabin and autonomous driving scenarios

In-cabin voice system

Datatang supports the collection and annotation of voice data, including noise, wake-up words.


Supports multiple vehicle models and multiple device collection and annotation of image datasets

Multi-sensor fusion

Supports multi-weather, multi-scene, multi-road condition, and multi-sensor data collection.

Point Cloud Object Detection

Supports the labeling of 3D or 2D/3D fusion target detection for various types of objects.

Point Cloud Object Tracking

Supports target tracking annotation of various objects in 3D or 2D/3D fusion.

Point Cloud Semantic Segmentation

Supports semantic, instance, or panoptic segmentation labeling for point clouds.

Our 3D Annotation Advantages

We also developed our own data annotation platform, which featured AI-assisted automatic object sizing, grounding, Grounding, object Rotating, etc."

Automate Object Resizing

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

Automatic Grounding

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

Automatic Flooring

Automatically aligns the 3D object with the ground, increasing annotation efficiency.

Automatic Object Detection

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

Automatic Object Rotation

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

Automatic Casting

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

Supports comprehensive annotation needs for speech, image, video, point cloud, and text data.

Success Stories

A car with radars and text

Customers need to annotate a large amount of road data. The data hall marks and divides targets such as obstacles, lane lines, driving areas, and traffic signs in 2D driving images, and annotates single frames, tracking, and segmentation of 3D point cloud data, including 2D-3D fusion annotations. Accuracy exceeds customer requirements, helping to rapidly improve self-driving technology and promote mass production.

Multi-sensor Fusion Labeling for Autonomous Vehicle

Customers want to improve the current driver intelligence analysis technology. Datatang provides data collection solutions of data on a range of dangerous driving behaviors such as sleeping, smoking, talking, eating, drinking and so on, while fully guaranteeing the security of the implementation. Camera angles, position, vehicle type and staff ratio are fully considered in the collection process.
