LiangDao Data Training Solution for Perception Algorithm

The development and iteration of intelligent driving features requires continuous optimization of perception algorithms, and the superiority of the algorithms depends on the effectiveness of data closure and the quality of training data. LiangDao's perception training data solution aims to support mass production driving development projects by assisting clients in testing, validating, evaluating, and training intelligent driving perception capabilities quickly as well as using data to drive autonomous driving system capabilities effectively and economically.

LD Data Solution includes:

  • Professional, customized vehicle modification and calibration services
  • Multi-sensor calibration, fusion data acquisition
  • High-quality automated and manual data processing
  • Data management with rich experience in mass production
  • Scenario mining and analysis that is both precise and easy to use
  • Efficient and accurate performance evaluation of perception algorithms

Data Acquisition Vehicle Platform Construction

The data required for perceptual training needs to be obtained from actual road data collection. LiangDao can support customers to set up data collection vehicles, including sensor configuration definition, equipment modification integration, system calibration and other services.
  • Over 1000 square meters workshop for modification engineering
  • Professional team of modification with 10 years+ experience
  • Professional sensor calibration software: LD Calibrator; data acquisition software: LD Logger

Sensor Calibration Software: LD Calibrator

LD Calibrator is a self-developed automated vehicle sensor calibration software, which supports the calibration of multiple sensors in a vehicle coordinate system.
  • Available in supporting one-click precise alignment of LiDAR and one-click calibration of camera internal and external parameters.
  • Supports the joint calibration of LiDAR and camera to make the multi-sensors data fusion more accurate and reliable.
  • Flexible deployment online, user-friendly interface and quick to get started.
  • Available in supporting multiple data input and output formats to meet various application requirements.

Data Acquisition Software: LD Logger

LD Logger is a data acquisition visualization software deployed on the vehicle side, self-developed by LiangDao. It is capable of supporting online timing and monitoring of sensor status, visualization of acquired data, scenarios tagging in real time, etc..
  • Multi-sensors (LiDAR, camera, CAN) data acquisition at the same time.
  • Real-time acquisition visualization of point cloud and camera images.
  • Real-time monitoring of acquisition devices status and feedback to users.

LD Data Management System

LD Data Management System (DMS) is a one-stop big data management platform on cloud that supports customers efficiently manage data and unlock the value of data. LD DMS connects multiple data function modules including data pre-processing, data automatic labeling, scenario mining, analysis and management, etc., and can realize resource management, data acquisition management, file management, pipeline management, scenario management, perception set management, objective database management, scenario labeling and other functions.
  • Flexibly deployable in public/private clouds or offline data centers.
  • Server-less deployment, supporting cross-cloud collaboration between public and private clouds.
  • Strict compliance with national data requirements, to ensure the data security.

Scenario Mining and Management System

The scenario mining and management system is deployed in LD DMS, which can directly realize scenario mining based on automatic labeling. The system can support customized scenario mining and supports the setting up to 1,000 parameters.
  • Effectively reducing the cost of data labeling and helping customers reduce costs and increase efficiency.
  • Scenario extraction and replay covering V2V interaction, human-vehicle interaction, etc..
  • Scenario-specific perception algorithms training to accelerate the iteration of perception function.

Data Labeling Service

AI perception algorithm training relies on high quality training and testing sets. The massive amount of acquisition data can be automatic labeled by LD ALT and manually labeled to form high-quality testing sets and training sets, which are used to output perception algorithm KPI evaluation reports and train perception algorithms until they meet the standards for series production.
  • Automatic labeling of multiple categories of dynamic and static objectives to improve data production efficiency.
  • Output high-quality perception training data sets to improve maturity of algorithm models .
  • Multi-dimensional quantitative perception algorithm KPI evaluation reports to help take focused training.
