单目高程网络检测

功能介绍​

elevation_net是基于hobot_dnn package开发的高程网络检测算法示例，在RDK上使用高程网络模型和室内数据利用BPU进行模型推理，从而得到算法推理结果。

代码仓库： (https://github.com/D-Robotics/elevation_net)

应用场景：单目高程网络检测算法通过解析图片得到像素点的深度和高度信息，主要应用于自动驾驶、智能家居、智能交通等领域。

支持平台​

平台运行方式示例功能
RDK X3, RDK X3 ModuleUbuntu 20.04 (Foxy), Ubuntu 22.04 (Humble)· 启动本地回灌，推理渲染结果保存在本地
RDK X5Ubuntu 22.04 (Humble)· 启动本地回灌，推理渲染结果保存在本地
X86Ubuntu 20.04 (Foxy)· 启动本地回灌，推理渲染结果保存在本地

准备工作​

RDK平台​

  1. RDK已烧录好Ubuntu 20.04/Ubuntu 22.04系统镜像。

  2. RDK已成功安装TogetheROS.Bot。

X86平台​

  1. X86环境已配置Ubuntu 20.04系统镜像。

  2. X86环境已成功安装tros.b。

使用介绍​

单目高程网络检测算法示例package采用读取本地图片的形式，经过算法推理后检测出Image基于像素的深度和高度信息，同时package将深度和高度信息进行处理，发布PointCloud2话题数据，用户可以订阅PointCloud2数据用于应用开发。

RDK平台​

# 配置ROS2环境
source /opt/tros/setup.bash

# 从tros.b的安装路径中拷贝出运行示例需要的配置文件。
cp -r /opt/tros/${TROS_DISTRO}/lib/elevation_net/config/ .

# 启动launch文件
ros2 launch elevation_net elevation_net.launch.py

X86平台​

# 配置tros.b环境
source /opt/tros/setup.bash

# 从tros.b的安装路径中拷贝出运行示例需要的配置文件。
cp -r /opt/tros/${TROS_DISTRO}/lib/elevation_net/config/ .

# 启动launch文件
ros2 launch elevation_net elevation_net.launch.py
