Berlin, March 21, 2025 – LiangDao, a global leader in 3D sensing technology, has been awarded the prestigious 2025 Tech.AD Award in the category “Data Labeling and Annotation“ for its intelligent data manufacturing toolchain, LD Data Factory. Powered by AI automation, the toolchain allows scalable data manufacturing while maintaining the highest quality and cost-efficiency.
Today, big data is the driving force behind the evolution of autonomous driving technology. The need for high-quality and reliable ground truth data is a major challenge in the industry. Additionally, the role of AI for training and validation of ADAS and AD functions is increasingly critical.
To tackle this challenge, LiangDao completed the platform development for LD Data Factory during a series project together with a world-leading Tier-1, delivering more than 50 million frames of 4D ground truth data. The toolchain has evolved into a comprehensive and highly automated solution, encompassing data input, pre-labeling, manual labeling, quality checks, output, and delivery.
"It's a great honor to receive the 2025 Tech.AD award”, said Dr. Shengguang Lei, CTO of LiangDao. “LD Data Factory addresses the high validation and training data requirements of our customers. With its high-level automation and proven track record, we are confident that this toolchain will bring substantial value to the industry by providing a scalable and cost-efficient solution for ground truth production.”
The key features of LD Data Factory include:
- VLM-based technology: Ensures data balance across diverse scenarios
- Automated pre-processing pipeline: Handles tasks like object detection, road feature extraction, SLAM algorithms for parking, and camera and LiDAR fusion
- LD Editor: A powerful annotation platform with full-stack labeling tools for Scenario, 2D, 4D time-based and BEV labeling
- Real-time quality feedback: Essential for ensuring consistent ground truth data
By leveraging this intelligent toolchain, labeling efficiency increases from 1:5000 to 1:500. The AI automation in both the pre-labeling algorithm and smart labeling tool achieves a 90% cost reduction compared to existing labeling methods. For customers, LD Data Factory ensures smooth adaptation with post-processing software that supports various LiDAR hardware and a modularized design, offering high flexibility and scalability.
