## 📖 使用说明
|
||
|
||
### 基本操作
|
||
|
||
#### 1. 启动系统
|
||
```bash
|
||
# 方式1: 分步启动 (推荐)

||
# 方式2: 一键启动
|
||
./start_system.sh
|
||
```
|
||
|
||
#### 2. 系统初始化
|
||
- 启动后保持雷达静止 **5-10秒**
|
||
- 等待系统完成初始化
|
||
- 看到 "Node init finished" 提示
|
||
|
||
#### 3. 开始定位
|
||

|
||
|
||
#### 4. 停止系统
|
||
```bash
|
||
# 停止各个进程
|
||
Ctrl+C # 在各个终端中
|
||
|
||
# 查看最终统计报告
|
||
# 距离计算器会自动显示总结
|
||
```
|
||
|
||
### 数据获取
|
||
|
||
#### 位置信息获取

|
||
# 实时位置 (单次)
|
||
ros2 topic echo /Odometry --once
|
||
|
||
# 持续监控
|
||
ros2 topic echo /Odometry
|
||
|
||
# 位置数据格式
|
||
header:
|
||
stamp: {sec: xxx, nanosec: xxx}
|
||
frame_id: camera_init
|
||
pose:
|
||
pose:
|
||
position: {x: 1.23, y: -0.45, z: 0.67} # 位置(米)

## 🐛 故障排除
|
||
|
||
### 常见问题
|
||
|
||
#### 1. 雷达连接失败
|
||
**症状**: 无法ping通雷达IP
|
||
```bash
|
||
# 检查网络配置
|
||
ip addr show
|
||
ping 192.168.1.194
|
||
|
||
# 解决方案
|
||
sudo ip addr add 192.168.1.5/24 dev eth0
|
||
sudo ip link set eth0 up
|
||
```
|
||
|
||
#### 2. 无定位数据输出
|
||
**症状**: `/Odometry`话题无数据
|
||
```bash
|
||
# 检查数据流
|
||
ros2 topic hz /livox/lidar
|
||
ros2 topic hz /livox/imu
|
||
|
||
# 可能原因和解决
|
||
# - 系统未初始化: 等待5-10秒
|
||
# - 需要运动激励: 缓慢移动雷达
|
||
# - 进程冲突: 重启所有进程
|
||
```
|
||
|
||
#### 3. 定位精度差
|
||
**症状**: 位置跳跃或漂移
|
||
```bash
|
||
# 检查环境
|
||
# - 确保有足够几何特征
|
||
# - 避免玻璃、镜面等反射面
|
||
# - 检查雷达安装稳定性
|
||
|
||
# 参数调优
|
||
ros2 param set /laser_mapping filter_size_surf 0.3
|
||
```
|
||
|
||
#### 4. RViz2显示异常
|
||
**症状**: 无点云或轨迹显示
|
||
```bash
|
||
# 检查Fixed Frame设置
|
||
# 确保设置为 "camera_init"
|
||
|
||
# 重启RViz2
|
||
pkill rviz2
|
||
ros2 run rviz2 rviz2
|
||
```
|
||
|
||
#### 5. 编译错误

# 高性能模式 (牺牲精度)
|
||
filter_size_surf: 0.8
|
||
filter_size_map: 0.8
|
||
cube_side_length: 500.0
|
||
|
||
# 高精度模式 (牺牲性能)

|
||
### 硬件优化建议
|
||
|
||
- **CPU**: 优先选择高主频多核处理器

||
### 自定义开发
|
||
|
||
#### 添加新的传感器
|
||
```cpp
|
||
// 在FAST_LIO中添加新传感器支持
|
||
// 1. 修改preprocess.h
|
||
// 2. 实现数据处理函数
|
||
// 3. 更新CMakeLists.txt
|
||
```
|
||
|
||
#### 扩展距离计算器
|
||
```python
|
||
# distance_calculator.py
|
||
class ExtendedCalculator(DistanceCalculator):
|
||
def __init__(self):
|
||
super().__init__()
|
||
# 添加新功能
|
||
|
||
def custom_analysis(self):
|
||
# 自定义分析功能
|
||
pass
|
||
```
|
||
|
||
#### 集成其他算法
|
||
```bash
|
||
# 添加新的SLAM算法
|
||
cd src
|
||
git clone https://github.com/your-slam-algorithm.git
|
||
|
||
# 修改launch文件
|
||
# 更新依赖关系
|
||
```
|
||
|
||
### 测试框架
|
||
|
||
```bash
|
||
# 单元测试
|
||
colcon test --packages-select fast_lio
|
||
|
||
# 集成测试
|
||
./scripts/integration_test.sh
|
||
|
||
# 性能测试
|
||
./scripts/benchmark.sh
|
||
```
