Question for lidar intensity input about 3dtrans HOT 2 CLOSED

@miaozhang97bosch
Your concern is valuable. We use [x, y, z] as the cross-domain setting (such as Uni3D and Bi3D) for alignment with previous research work, such as ST3D. However, we also believe that intensity is important for distinguishing different objects obtained using LiDAR. Therefore, it may be beneficial to conduct cross-domain research that includes the intensity for the cross-domain 3D object detection.

Additionally, since AD-PT is the first work to study how pre-trained model parameters can be fine-tuned to different datasets, we adopted the experimental setting of [x, y, z, intensity] (or [x, y, z, intensity, elongation] for Waymo), utilizing all the information obtained from the employed LiDAR.

Got it. Thanks for your reply.
