Hi, The field was added probably right around when you originally commented to [metrics.proto](https://github.com/waymo-research/waymo-open-dataset/blob/master/waymo_open_dataset/label.proto#L89). We recommend three main resources for the challenge: 1) The [challenge overview page](https://waymo.com/intl/en_us/open/challenges/2022/3d-camera-only-detection/) contains descriptions of...

Hi, - All LiDAR labels that are visible in at least one camera have `camera_synced_box` and `most_visible_camera_name` populated. For the 3D Camera-only Detection Challenge, at least V1.3.1 of the dataset...

Hi! V.1.3.2 should contain this field. Is it possible that your proto definition (label.proto) is not up-to-date? The field is defined [here](https://github.com/waymo-research/waymo-open-dataset/blob/17f070076dad149766357b31e25d27cf8b5da6ac/waymo_open_dataset/label.proto#L89).

Hi, thank you for your interest in the Block-NeRF dataset! We will add some more instructions to the website shortly. In the meantime, you can follow the example below: ```...

Hi, you should find that the training split contains about 11,269 and the validation split contains about 576 images. Could you let me know how you counted the number of...

Hi Haibao, In Waymo Open Dataset, the 5 cameras are closely located to the top (main) LiDAR. Therefore, you can assume that the occlusion patterns between these to be quite...

Hi Haibao, Glad this was helpful! Regarding your follow-up question, we do believe that re-identification is valuable in practice as it allows for better reasoning about the history of a...

Hi, Thanks for flagging this. It is possible that this is a labeling mistake. Could you provide more details? In particular, frame.context.name as well as the ID of the affected...

Hi there, could you share more details on which specific steps are causing trouble? (logs, artifacts, error messages etc.). Thanks!

Hi Stefano! You can find the focal length in px in the `camera_calibrations` field. Unfortunately, we can not share more details of the sensor, including its size.
