Change the trajectory of Ego Vehicle

Closed this issue 6 months ago · 7 comments

Hey, I've trained CarNeRF on Scene05 and the rendered video is great. I wanted to change the trajectory of the ego vehicle(the vehicle from where the video is shot) I tried experimenting by changing pose and rotation in cicai_render.py but of no use. Could you let me know how can the trajectory of the ego vehicle be changed?

Hi! @amoghskanda

You can refer to this issue #80.

camera_to_worlds in cicai_render.py is just commented out in your latest commit. Rendering using nerfstudio isn't working so i'm rendering using the script, any other way to change trajectory of ego?

You can uncomment the camera_to_worlds and have a try.

Is there something that can be changed in mars_kitti_dataparser.py that can aid with changing the trajectory of the ego? If anyone has done it, could you let me know?

You can uncomment the camera_to_worlds and have a try.

In fact,I wonder if I can change the "trajectory" of camera, not the "view" of camera.

I tried adding a sine wave to the poses_imu_tracking tensor and the poses_imu_w_tracking tensor in the mars_kitti_datasparser.py file and it got me somewhere. That changes the trajectory of other objects as well. If the ego is stationary, you might not see any results.
