Apriltag as a reference cordinate
-
Hello,
I would like to use apriltag as a reference (0, 0, 0). I mean, for example, when the drone detects the tag, show it in the "T_imu_wrt_vio (m)" (0, 0, 0) coordinate.
How can I do that?Drone Model: RB5

Amin@Amin-Bassiri could you please someone answering my question.

@Amin-Bassiri could you please someone answering my question.
@Amin-Bassiri , can you please clarify the question?
The april tag detector detects the tag in the camera frame and using extrinsics file, the tag's coordinate can be converted into the vehicle's reference frame.
With that in mind, what would you like to do? What is unclear to me is the following statement : "show it in the "T_imu_wrt_vio (m)" (0, 0, 0) coordinate"

I have an RB5 drone that I plan to fly indoors, but I require very accurate localization. For this purpose, I need a fixed reference coordinate system. For example, I want to designate point A (associated with Apriltag0) as (X=0, Y=0, Z=0). This means that even if the drone flies away and later returns to point A, once it detects the AprilTag, its coordinates should reset exactly to (0, 0, 0) without any error.
Since I plan to fly the drone multiple times along a route from point A to point B and back to point A, I need the system to reliably reset the drone’s position to (0, 0, 0) whenever it sees Apriltag0—even if there are slight changes in the tag's position.
How can I achieve this using the AprilTag as a reference coordinate?
I want to reset T_imu_wrt_vio to 0,0,0, when the drone detect the Apriltag.

Problem solved,
Thanks anyway
