This invention discloses a
data annotation method and
system for autonomous driving, relating to the field of
data annotation. First, multi-source sensor data is acquired and initially annotated using an automated model. Then, a joint optimization
algorithm decomposes and reconstructs features, improves boundary
annotation accuracy, and identifies low-confidence regions. Based on a deep active learning strategy, prediction entropy, Bayesian
divergence, and task-level uncertainty are fused to screen high-value samples.
Ground truth labels are obtained through manual
verification, while low-confidence regions are optimized to generate supplementary labels. These two types of labels are used as incremental training data, and the model mapping matrix is updated through topological residual projection. Finally, the model is deployed for road testing, and problematic data is collected, triggering a new
annotation optimization process to form a closed-loop iteration. This invention improves
annotation accuracy and efficiency, achieves efficient incremental model updates, and constructs a continuously evolving annotation
closed loop, providing support for the iteration of autonomous driving models.
