Current behavior? I am trying to compute gradients for atf.vectorized_mapped function nested within a call totf.while_loop(and hence alsotf.map_fn) as inthis (trivial!) Colab example. The top level function can compute its return value in all three execution modes (eager, graph, XLA). I...

这一部分,就是作者希望在基于Map Element Detector生成的带关键点的polyline上,以类似RNN的方式来迭代的生成下一个顶点,如果生成了end of sequence token(EOS),就表示生成完毕。作者采用transformer decoder来建模顶点的位置,每次的输入包括三部分内容: Label Embedding: 基于Map Element Detector输出的Polyline的class生成...
在我们的实验中,VectorMapNet 在 nuScenes 数据集上实现了强大的高清地图学习性能,超过了之前最先进的方法 14.2 mAP。从质量上看,我们也表明 VectorMapNet 有能力生成全面的地图,并能捕捉到更多细粒度的道路几何细节。据我们所知,VectorMapNet 是第一个旨在解决端到端矢量高清地图学习问题的工作。我们的项目网站可访...
本文提出的VectorMapNet接受传感器的输入,直接得到稀疏的bev下的地图元素polyline集合,同时直接获取这些元素的连接关系,对下游任务很友好。在nuscenes数据集上超过之前的sota 14.2mAP. 引言: 以语义分割的方式解决地图问题存在的问题是,1.有时候需要区分相同语义的不同元素,比如坐车道和右车道;2.地图元素需要一种压缩的...
In autonomous driving, there is growing interest in end-to-end online vectorized map perception in bird's-eye-view (BEV) space, with an expectation that it could replace traditional high-cost offline high-definition (HD) maps. However, the accuracy and robustness of these methods can be ...
aChapter 5 shows the results and compares the vectorized map with respect to the way it handles curves and junctions and error analysis by calculating the mean and standard deviation. 第5章显示结果并且比较vectorized它通过计算卑鄙和标准偏差处理曲线和连接点和错误分析的地图关于方式。 [translate] ...
To overcome this problem, we propose an online map construction system that exploits the long-term temporal information to build a consistent vectorized map. First, the system efficiently fuses all historical road marking detections from an off-the-shelf network into a semantic voxel map, which is...

VectorMapNet: End-to-end Vectorized HD Map Learning Autonomous driving systems require High-Definition (HD) semantic maps to navigate around urban roads. Existing solutions approach the semantic mapping problem by offline manual annotation, which suffers from serious scalability issues. Recent learning-...
