Establishment of Technology for Automatic Evaluation of Remote Monitoring Video Quality for Level 4 Autonomous Driving

NTT has established Parametric object-recognition-ratio-estimation model1, a technology that automatically estimates whether remote monitoring video and vehicle-related information transmitted from autonomous vehicles to the remote control room are of sufficient quality to reliably detect objects suddenly appearing in front of the vehicle. ITU-T SG122 has verified the high accuracy of the Parametric object-recognition-ratio-estimation model and adopted it as the new ITU-T Recommendations P.1199 in November 2025.
