Weather during recording , always set to sunny? #210

Open ShravanthiPatil opened 4 years ago

ShravanthiPatil commented 4 years ago

Hello, I noticed that the field- weather during recording has been set to sunny in every segment of all validation TFrecords. Is that correct? Kindly clarify.

There are two levels of detection, level1, and level2, however, I read in the research paper that Level2 also includes level1. I wanted to have a separate subset that includes only occluded pedestrians, and I initially assumed selecting Level2 detection difficulty would suffice, but it isn't so. Is there a way, to determine only occluded pedestrians?

Also, do you already have the statistics for total number of objects annotated in the dataset? such as the number of unique pedestrians, the number of occluded pedestrians, and the density of pedestrians in the dataset, the number of pedestrians captured during the night, dawn, dusk?

I assumed the dataset was recorded in different weather conditions like rainfall, sunny, snowfall, foggy. I did find a few images captured in foggy conditions. However, I couldn't find those for snowfall or rainy. Could you please direct me to the specific dataset folder which is captured during such adverse weather conditions?

Awaiting your response!

Regards, Shravanthi

  1. We have another domain adaptation dataset which mainly consists of rainy scenes.
  2. no, we do not provide a way to do that. you can do that based on your problem setting.
  3. Check our paper which has some stats.

Hello, Did waymo dataset include lidar point cloud data of both clear weather and rain (fog) in the same scene? I wanna use Lisa rain augmented method based on clear weather and compare the generated results with that of rain weather in real world.

Awaiting your response! Best, Zilin

Hello,

I am facing the same issue, where all my extracted records (training set, front camera images) only show sunny weather conditions in the label. However i have noticed some pictures which are actually foggy, yet the weather condition is labeled as sunny.

  1. How the weather condition is decided and labeled in the waymo dataset?
  2. What is the domain adaptation dataset that you mentioned in the first reply? (which contains rainy conditions)
