|
|
### Task-GCA创新
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
核心思想:
|
|||
|
|
检测和分割任务对BEV特征的需求不同
|
|||
|
|
→ 为每个任务独立学习通道注意力
|
|||
|
|
→ 各取所需,互不干扰
|
|||
|
|
|
|||
|
|
实现:
|
|||
|
|
BEV特征 (512ch)
|
|||
|
|
├─→ Detection GCA → 检测优化特征 → TransFusion
|
|||
|
|
└─→ Segmentation GCA → 分割优化特征 → EnhancedHead
|
|||
|
|
|
|||
|
|
优势:
|
|||
|
|
✅ 检测关注移动物体 (car, pedestrian)
|
|||
|
|
✅ 分割关注静态区域 (lane, road)
|
|||
|
|
✅ 避免任务冲突
|
|||
|
|
✅ 参数共享 + 任务定制
|
|||
|
|
|
|||
|
|
参数:
|
|||
|
|
每个GCA: 1.4M
|
|||
|
|
总增量: 2.8M (+2.5%)
|
|||
|
|
```

## 🔍 最新研究方向
|

|
|
### Enhanced Camera Adapter (新提出)
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
问题:
|
|||
|
|
当前BEVFusion固定6 cameras
|
|||
|
|
→ 无法支持不同车型配置
|
|||
|
|
→ 无法处理camera故障
|
|||
|
|
→ 无法优化不同camera类型
|
|||
|
|
|
|||
|
|
解决方案: Enhanced Camera Adapter
|
|||
|
|
✅ 支持动态数量 (1-12 cameras)
|
|||
|
|
✅ 支持不同类型 (wide/tele/fisheye)
|
|||
|
|
✅ 支持不同位置 (3D position encoding)
|
|||
|
|
✅ 自动学习camera重要性权重
|
|||
|
|
|
|||
|
|
设计:
|
|||
|
|
Adapter = Type-Specific Module ⊕ Position Encoder
|
|||
|
|
|
|||
|
|
每个camera:
|
|||
|
|
1. 根据type选择adapter
|
|||
|
|
2. 根据position生成embedding
|
|||
|
|
3. Fusion两者
|
|||
|
|
4. 输出adapted feature
|
|||
|
|
|
|||
|
|
优势 vs MoE:
|
|||
|
|
✅ 更清晰 (可解释)
|
|||
|
|
✅ 更稳定 (易训练)
|
|||
|
|
✅ 更高效 (+6M参数)
|
|||
|
|
✅ 更通用 (任意配置)
|
|||
|
|
|
|||
|
|
实现:
|
|||
|
|
文档: CAMERA_ADAPTER_ENHANCED_DESIGN.md
|
|||
|
|
代码: 待实现
|
|||
|
|
时间: 5天 (1天代码 + 1天测试 + 3天训练)
|
|||
|
|
```

## 💡 技术亮点
|
|||
|
|
|
|||
|
|
### 1. Task-specific GCA (当前核心)
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
创新点:
|
|||
|
|
传统: 检测和分割共享相同BEV特征
|
|||
|
|
问题: 任务需求冲突,相互干扰
|
|||
|
|
|
|||
|
|
Task-GCA: 每个任务独立选择特征
|
|||
|
|
优势:
|
|||
|
|
- 检测关注动态目标 (cars, pedestrians)
|
|||
|
|
- 分割关注静态结构 (lanes, roads)
|
|||
|
|
- 互不干扰,各取所需
|
|||
|
|
|
|||
|
|
实现:
|
|||
|
|
self.task_gca = {
|
|||
|
|
'object': GCA(512ch, reduction=4),
|
|||
|
|
'map': GCA(512ch, reduction=4),
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
bev_feat (512ch)
|
|||
|
|
├─→ task_gca['object'] → detection_feat → TransFusion
|
|||
|
|
└─→ task_gca['map'] → segmentation_feat → EnhancedHead
|
|||
|
|
|
|||
|
|
参数: +2.8M (minimal overhead)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 2. EnhancedBEVSegmentationHead
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
创新点:
|
|||
|
|
1. ASPP: 多尺度上下文 (1x1, 3x3, 5x5, 7x7)
|
|||
|
|
2. Deep Decoder: 4层渐进上采样
|
|||
|
|
3. Attention: Channel + Spatial双重注意力
|
|||
|
|
4. Deep Supervision: 多级loss监督
|
|||
|
|
5. Dice Loss: 处理类别不平衡
|
|||
|
|
6. GroupNorm: 解决分布式训练不稳定
|
|||
|
|
|
|||
|
|
架构:
|
|||
|
|
Input: 512ch BEV feature
|
|||
|
|
├─ ASPP: 多尺度提取
|
|||
|
|
├─ Channel Attention: 关注重要通道
|
|||
|
|
├─ Spatial Attention: 关注重要区域
|
|||
|
|
├─ Deep Decoder:
|
|||
|
|
│ └─ 512→256→256→128→128 (4层)
|
|||
|
|
├─ Deep Supervision: 每层都有loss
|
|||
|
|
└─ Output: 6类分割
|
|||
|
|
|
|||
|
|
参数: +15M
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3. GroupNorm解决方案
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
问题:
|
|||
|
|
BatchNorm在分布式训练中:
|
|||
|
|
- 每个GPU独立计算统计量
|
|||
|
|
- 8个GPU → 8个不同的BN统计
|
|||
|
|
- 导致不稳定、收敛困难
|
|||
|
|
|
|||
|
|
GroupNorm:
|
|||
|
|
- 在通道维度分组计算
|
|||
|
|
- 独立于batch大小
|
|||
|
|
- 适合小batch (1/GPU)
|
|||
|
|
|
|||
|
|
实现:
|
|||
|
|
nn.BatchNorm2d → nn.GroupNorm(32, channels)
|
|||
|
|
|
|||
|
|
效果:
|
|||
|
|
✅ 训练稳定
|
|||
|
|
✅ Loss正常收敛
|
|||
|
|
✅ 无梯度爆炸
|
|||
|
|
```

## 📞 监控与调试
|
|||
|
|
|
|||
|
|
### 实时监控命令
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
# 1. 查看训练日志 (实时)
|
|||
|
|
cd /workspace/bevfusion
|
|||
|
|
tail -f runs/run-326653dc-2334d461/*.log | grep "mmdet3d - INFO"
|
|||
|
|
|
|||
|
|
# 2. 查看GPU状态
|
|||
|
|
nvidia-smi -l 1
|
|||
|
|
|
|||
|
|
# 3. 查看进程
|
|||
|
|
ps aux | grep train.py
|
|||
|
|
|
|||
|
|
# 4. 查看最新性能
|
|||
|
|
tail -100 runs/run-326653dc-2334d461/*.log | grep "Epoch"
|
|||
|
|
|
|||
|
|
# 5. 查看loss趋势
|
|||
|
|
tail -500 runs/run-326653dc-2334d461/*.log | grep "loss:" | awk '{print $NF}'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 异常处理
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
# 如果训练卡住:
|
|||
|
|
1. 检查GPU: nvidia-smi
|
|||
|
|
2. 检查进程: ps aux | grep train
|
|||
|
|
3. 如果无响应超过30分钟 → kill重启
|
|||
|
|
|
|||
|
|
# 如果OOM:
|
|||
|
|
1. 降低batch_size: samples_per_gpu 1 → 1 (已最小)
|
|||
|
|
2. 或减少GPU: 8卡 → 6卡
|
|||
|
|
|
|||
|
|
# 如果loss爆炸:
|
|||
|
|
1. 检查学习率
|
|||
|
|
2. 检查梯度: grad_norm > 100 → 异常
|
|||
|
|
3. 考虑重新从上一个checkpoint开始
|
|||
|
|
```
|
|||
