About world coordinate #116

Closed ChencongZJU closed 1 year ago

ChencongZJU commented 1 year ago

Hi, thanks for your great work. I'm trying to use get3d to generate vehicle models for vehicle in real data scenario. My problem is about world coordinate. Is the center of the world coordinate system at the center of the car? And what direction does its x-y-z axis point to？

Hi @ChencongZJU ,

Thanks for your interest in our work!

You can run the inference on our pretrained checkpoint and visualize the 3D shape in meshlab to see what each direction would point to :)

To answer your question, yes, the center of the world coordinate system is at the center of the car (0,0,0), and the x-axis is the frontal of the car, y-axis is the top of the car, z-axis is the side of the car.
