6-DOF IS A TERM THAT INDICATES THE FREEDOM OF MOVEMENT OF A RIGID BODY IN THREE-DIMENSIONAL SPACE
6-DOF means “Six Degrees of Freedom” the body can change position with these transitions:
These are translation in three perpendicular axes.
The orientation can also change, with a rotation about three perpendicular axes, often called:
3 Translations + 3 Rotations = 6 Degrees of Freedom = 6-DoF!
Any possible movement of a rigid body, simple or complex, can be expressed with a 6 DOF combination.
For example, imagine when a golf ball is hit by a bat: the complex movement of the bat can be censidered as a combination of different translations and rotations, as 6-DoF.
Accuware Dragonfly can provide the location data in the 6-DoF format.
Dragonfly is a Visual SLAM technology, and its API provide the location of the device in 6-DOF format, as well as in WGS-84 (latitude, longitude, elevation). The API provides typically a JSON containing the location data, however we can customize the output format to address specific requirements.
The X, Y, Z coordinates measure the distance, in meters, from an “origin” having coordinates (0,0,0). You can imagine it to be, for example, the corner of a room, and the device is laying on the floor. This is the origin point: every movement that the device makes is calculated in meters, therefore, assuming that the device moves by 50 cm on the X asis, and elevates by 75 cm, the new coordinate will be (0.5, 0, 0.75).
The coordinates can have negative values, too, always relative to the origin.
Dragonfly offers a centimeter level accuracy, and provides 6-DoF location data.
Dragonfly’s location can be integrated into custom applications, of course: the location can be used as a component for robots and drones autonomous navigation, or to track the location of moving machines, vehicles, forklifts, UAV… The data provided by Dragonfly can be customized by Accuware in order to fit different projects, and we are open to listen to your requests. Accuware can provide ROS nodes upon request to integrate Dragonfly SLAM for ROS.
