仿真环境启动指南
本文档说明如何单独启动 Isaac 仿真环境的各个组件。
前置条件
# 先 source ROS2 环境
source install/setup.bash
单独启动组件
1. Isaac 仿真环境
# 带可视化界面
python3 src/simulation/tools/launch_sim_stack.py --component isaac
# headless 模式(无界面)
python3 src/simulation/tools/launch_sim_stack.py --component isaac --headless
2. 仿真车端统一 Agent
包含底盘、运控、传感器数据转发:
python3 src/simulation/tools/launch_sim_stack.py --component vehicle-agent
3. 外部位姿桥
将 Isaac 真值转发给车端:
python3 src/simulation/tools/launch_sim_stack.py --component external-pose-bridge
4. 车间侧传感器 Ingest
从车端轮询传感器数据:
python3 src/simulation/tools/launch_sim_stack.py --component sensor-ingest
5. 车间 Gateway
ROS2 节点,对接底盘/运控:
python3 src/simulation/tools/launch_sim_stack.py --component gateway
启动完整仿真链路
方式一:一键启动所有仿真组件(不含车间总控)
python3 src/simulation/tools/launch_sim_stack.py --component all
方式二:分步启动(推荐用于调试)
终端 1 - 启动 Isaac:
python3 src/simulation/tools/launch_sim_stack.py --component isaac
终端 2 - 启动车端 Agent:
python3 src/simulation/tools/launch_sim_stack.py --component vehicle-agent
终端 3 - 启动外部位姿桥:
python3 src/simulation/tools/launch_sim_stack.py --component external-pose-bridge
终端 4 - 启动传感器 Ingest:
python3 src/simulation/tools/launch_sim_stack.py --component sensor-ingest
终端 5 - 启动车间 Gateway:
python3 src/simulation/tools/launch_sim_stack.py --component gateway
终端 6 - 启动车间总控:
ros2 launch win_ubuntu_bridge minimal_workshop_demo.launch.py \
use_gateway:=true \
chassis_host:=127.0.0.1 \
control_host:=127.0.0.1 \
sensor_registry:=demo_front_camera,demo_down_camera,demo_lidar_3d,demo_lidar_2d,demo_imu
验证仿真环境
启动后检查 topic:
# 查看 Isaac 发布的传感器数据
ros2 topic list | grep isaac
# 检查各传感器数据频率
ros2 topic hz /sensor/front_camera/image_raw
ros2 topic hz /sensor/down_camera/image_raw
ros2 topic hz /sensor/lidar_3d/pointcloud
ros2 topic hz /sensor/lidar_2d/scan
ros2 topic hz /sensor/imu/data
# 检查外部位姿
ros2 topic hz /isaac/external_localization/telemetry
执行端到端验收测试
仿真环境启动后,执行验收:
python3 src/simulation/tools/smoke_test_workshop_orchestrator.py \
--verbose-feedback \
--no-publish-fake-external-telemetry
停止仿真环境
按 Ctrl+C 停止各组件,或使用:
./stop_isaac_real_sim_stack.sh
快捷脚本
也可以使用一键测试脚本(启动所有组件并执行验收):
# 完整测试(启动 + 验收 + 停止)
./run_isaac_real_sim_test.sh
# 保持运行(不执行验收)
./run_isaac_real_sim_test.sh --no-smoke --keep-running
# headless 模式
./run_isaac_real_sim_test.sh --headless
