Period: 2022 - Present
Responsibilities:
Ground Truth System
Development Perception model for Grount Truth System: Based on PersFormer and BEVFusion, use Lidar point as 3D PE to guide the height of BEV feature map. Apply min-cost flow for matching to contrast DETR-like loss.
Data selection: use Perceptre-hash, Timestamps, and IMU information to select divergence data for human annotation.
Annotation quality check: use CLIP-IQA to select blurred, bad samples from the dataset. Using Grounded-SAM and other rule-based functions to check lane line labeling quality.
Setup & maintain IT Lab and department local AI training cluster
Build up a local registry for docker images.
Fulfill ITL network requirements & DevOps by using Ansible and playbook.
Build a monitor based on Grafana & Prometheus.
Build high-concurrent DFS for computer vision case by Ceph.
