ros-image-rotate

This ROS node listens to image messages, rotates them according to the specified angle and scale, and publishes to a new topic. It helps in camera image rotation under real-time conditions.

Installation

Navigate to the src directory of the catkin workspace (e.g., ~/catkin_ws):

cd ~/catkin_ws/src

Clone the repository into src directory and rename it to image_rotate:

git clone https://github.com/zhuxuanya/ros-image-rotate.git image_rotate

Return to catkin workspace root and rebuild:

cd ..
catkin_make

Source the environment to update the workspace:

source devel/setup.bash

Usage

List all connected video devices to determine the correct device number (e.g., /dev/video0):

# sudo apt install v4l-utils
v4l2-ctl --list-devices

Modify the corresponding device parameter in usb_cam node and run it with the image_rotate node:

roslaunch image_rotate image_node.launch
