Job description

1、负责基于车载图像/视频数据,研发高精度的路牌/交通标志检测、跟踪与分类算法;利用最新视觉大模型(VLM)及场景文本识别(OCR)技术,实现复杂路牌的信息提取与版面分析;
2、结合BEV(鸟瞰图)感知架构与多视图几何技术,将2D图像中的路牌/交通标志精准投影至3D空间,实现目标的高精度绝对坐标解算与3D矢量化表达;
3、研发关联算法,解析路牌内容与当前道路、车道的拓扑指向关系(如悬空路牌对应特定车道);
4、构建端到端的“路牌/交通标志”自动化标注产线与变化检测(Change Detection)算法。

1、本科及以上学历,计算机、人工智能、自动化、电子工程等相关专业;
2、精通CNN、Transformer、ViT等主流深度学习架构;
3、熟悉自然场景文本检测与识别(STR/OCR)算法;
4、精通Python/C++,具备优秀的算法实现与优化能力;
5、熟练使用PyTorch,熟悉TensorRT/ONNX等模型量化与加速工具。

加分项
1、深入理解并实践过BEV感知(如BEVFormer等)、端到端矢量化建图(如MapTR等)算法;
2、有Vision-Language Model(VLM)、SAM等视觉大模型在实际业务中微调和落地经验;
3、有地图自动化产线研发经验,或参与过“数据闭环/自动标注”系统搭建。
