The document states that computer vision and stereo SLAM technology was used to estimate the position.
Do you mean that only vision technology was used for ZED 2i position estimation, or that an IMU was integrated through sensor fusion such as a Kalman filter?
Hi @LeeHyokBeen
the positional tracking uses VIO algorithms, fusing visual odometry with inertial information.
Kalman Filters are obviously used, but I cannot provide more details because this is a piece of closed information.
Is there a calibrated (Visual Inertial Odometry) translation velocity parameter (vx,vy,vz) like the calibrated position data(VIO) or do I need to divide the position by the time?
I was trying to find the information of linear velocity (vx, vy, vz).
However, I can’t find any function or parameter for linear velocity (speed of translation).
I can only find angular velocity or linear acceleration.
How can I reach the calibrated linear velocity of the ZED 2i using the C++ API?
