Data Annotation Tools

Our platform is embeded with 30 annotation template and supports automatic object resizing, grounding, detection, rotation, casting and 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.

Case Studies

A car with radars and text

The client needs to label a large amount of road data. Datatang annotates the objects in 2D images such as obstacles, lane lines, drivable areas and traffic signs with bounding boxes and segment, and performs single frames, tracking and segmentation, 2D-3D fusion labeling for 3D point cloud data. The accuracy exceeds the customer's requirements, assisting client rapidly improve the self-driving technology and promote mass production.

Multi-sensor Fusion Labeling for Autonomous Vehicle

Client wants to improve the current driver monitor system. Datatang help client collect a series of dangerous driving behavior data, such as sleeping, smoking, talking, eating, drinking and etc., while fully guaranteeing the safety of implementation. Camera angles, position, vehicle type and ollection personnel ratio are fully considered in the collection process.
