Public Member Functions | |
| void | addHandle (mesh_filter::MeshHandle handle, const std::string &name) |
| registers a mesh with its handle | |
| bool | getTransform (mesh_filter::MeshHandle handle, Eigen::Affine3d &transform) const |
| returns the current transformation of a mesh given by its handle | |
| void | setFrame (const std::string &frame) |
| sets the camera frame id. The returned transformations are in respect to this coordinate frame | |
| void | setUpdateInterval (unsigned long usecs) |
| sets the update interval in micro seconds. This should be low enough to reduce the system load but high enough to get up-to-date transformations. For PSDK compatible devices this value should be around 30000 = 30ms | |
| void | start () |
| starts the updating process. Done in a seperate thread | |
| void | stop () |
| stops the update process/thread. | |
| TransformProvider (unsigned long interval_us=30000) | |
| Constructor. | |
| ~TransformProvider () | |
| Destructor. | |
Private Member Functions | |
| void | run () |
| The entry point of the dedicated thread that updates the transformations periodically. | |
| void | updateTransforms () |
| this method is called periodically by the dedicated thread and updates all the transformations of the registered frames. | |
Private Attributes | |
| std::string | frame_id_ |
