This article introduces ADMap, a method for reconstructing online vectorized high-precision maps anti-interference framework. In the field of autonomous driving, online reconstruction of high-precision maps is crucial for planning tasks. In recent years, a variety of high-performance high-precision map reconstruction models have been developed to meet this demand. However, due to prediction bias, the point sequence within the instance vector may appear jittered or jagged, which will affect subsequent tasks. To this end, this paper proposes an anti-interference map reconstruction framework ADMap. The ADMap framework consists of three modules, namely multi-scale perceptual neck (MPN), instance interactive attention (IIA) and vector direction difference loss (VDDL). By exploring point order relationships between instances and within instances in a cascade manner, this model can more effectively monitor the point order prediction process, thereby alleviating the problem of point order jitter. Experiments demonstrate that ADMap achieves state-of-the-art performance on nuScenes and Argoverse2 datasets. A large number of results show that ADMap can generate stable and reliable map elements in complex and changeable driving scenarios. This is critical to the safety and accuracy of autonomous driving systems. In summary, ADMap is an innovative anti-interference map reconstruction framework that can effectively solve the point order jitter problem and demonstrate excellent performance on actual data sets. This research is of great significance in promoting the development of autonomous driving technology.
The contributions of this article are as follows:
1) This article proposes an end-to-end ADMap, which can reconstruct More stable vectorized high-precision map;
MPN can capture multi-scale information more accurately without increasing computing resources. IIA effectively realizes the interaction of information between instances and within instances, thereby alleviating the problem of instance point position offset. In addition, VDDL utilizes topological information to supervise the reconstruction process of point-order positions and models vector direction differences.
3) ADMap is able to reconstruct vectorized high-precision maps in real time and achieves the best performance in nuScenes and Argoverse2 benchmarks.
