Hello! I also found that there is no camera data timestamp in California version. Namely, when I tried to extract the camera and IMU data form the ROS bag using Kalibr (after a little modification to support compressed_imgmsg), I found the timestamps of all images are zero. The command I used was kalibr_bagextractor --image-topics /camera_array/cam0/image_raw/compressed --imu-topics /imu_raw --output-folder dataset --bag ../CA-20190828194706_blur_align.bag I also have tried UrbanNav-HK-Data20190428 in urbannav dataset and successfully got the correct timestamps when extracting the data by Kalibr. How can I get the timestamps of the images in California version in this dataset? Thank you in advance!
