transformStamped QML Value Type

This expresses a transform from coordinate frame header.frame_id to the coordinate frame child_frame_id at the time of header.stamp. More...

Properties

• childFrameId : string
• header : header
• transform : transform

Detailed Description

This message is mostly used by the tf2 package. See its documentation for more information.

The child_frame_id is necessary in addition to the frame_id in the Header to communicate the full reference for the transform in a self contained message.

transformStamped is a structured value type usable in QML. It maps directly to the geometry_msgs::msg::TransformStamped ROS 2 message type.

Construct a transformStamped in QML by assigning a JavaScript object whose keys are its component properties, or by setting those properties individually.
