ROS TF Coordinate Transformation: TF Tree
1. Introduction to TF Tree
In robotic systems, there exist kinematic and dynamic models. For rigid-body robots, the dynamic model is based on rigid body dynamics and represents the relationship between forces/torques and motion states during robot motion. The kinematic model, on the other hand, consists of a series of coordinate frames attache ...

Single Channel Display in OpenCV
When extracting and displaying a single B, G, or R channel from a full-color image, the result appears as a grayscale image. This is not actually a grayscale representation—it uses black, white, and shades of gray for display purposes. The intensity corresponds to the channel's value: brighte ...
