Transformation of relative pose to absolute pose

[lucleon]

In line 94 in test.py, the Rotation Matrix is computed using only one Euler angle:

ang = eulerAnglesToRotationMatrix([0, answer[-1][0], 0])

I'm wondering, why are theta_x and theta_z set to zero?

@ChiWeiHsiao @lucleon Hi , I have same questions.

I have the same problem, and when I evaluate the error of relative pose, the error is very large, but the trajectory fits well. Have you solved it? @fangxu622 @lucleon @ChiWeiHsiao

KITTI is recorded from the trajectory of a car. This movement does not have pitch and roll. The only angle change is yaw.

In my opinion,This is due to in test.py,they measure the loss in absolute pose,which is different from training

It's worked out. This is the absolute pose. It can be solved by processing the pose data in the data set as relative pose.Hope to help you!
