The Dynamic Ground Truth (DGT) system is an independent reference measurement solution, which can be mounted on standard roof racks to enable universal, flexible application.
The object-recognition shall not be based on the internal vehicle sensors, but on a third-party system. It should be manufacturer-independent, highly precise, and universally applicable.
AVL DGT fulfills all these requirements as a one-box solution with an integrated calibration concept.

360° -Field of View
The DGT system lets you capture an accurate 360° field of view of the test vehicle, allowing the verification and validation of all automated driving functionalities.
Accurate Data Acquisition
The image it captures comprises lidar, camera, and high-precision GNSS sensors, offering an extremely accurate view of the vehicle and its systems’ test environments. The sensor-messages are time-stamped accurately with the GPS-time.
Highly Precise Comparison between the DGT and the SUT (System Under Test)
To enable the comparison of DGT-system data and the system under test (SUT)-data, the clocks of the SUT-logger and the DGT can be synchronized.
Seamless data processing
During test trips data are collected with the DGT system and the vehicle under test. The data is transferred to a data center once the vehicle returns to the garage. From there, the data is available for further processing using our cloud-based ADAS/AD Big Data and Analytics Platform.
