@christopi I wonder how you fixed it, I met the same problem about axis. it's changing the network output or postprocessing using tool like PCA or bbox?

should fix camera angles and rotate after it is rendered as a object using a rotate function

LRMridiot commented 2 weeks ago

is that mean should know input-image's camera angles and then correct it or input images at fixed angle like front view?

@christopi Hello, I know I need to use rotation functions, but I feel that the rotated mesh still doesn't match the original view. How should I adjust the camera angle to make it consistent?
