The google drive links on the download page don't work for me.

Here are files that I have download for others to use.

CDE-packages

• EDIT: we now have Docker in the master, see PR Ubuntu 20.04 and CI Dockerfiles #515!!
• Use the docker image from Stereo Labs
• https://github.com/ethz-asl/kalibr/wiki/installation#c-using-through-docker
• https://hub.docker.com/r/stereolabs/kalibr

Sample datasets

• Use the EurocMav calibration datasets instead
• http://robotics.ethz.ch/~asl-datasets/ijrr_euroc_mav_dataset/calibration_datasets/
• Camera calibration: http://robotics.ethz.ch/~asl-datasets/ijrr_euroc_mav_dataset/calibration_datasets/cam_april/cam_april.bag
• Calibration board: http://robotics.ethz.ch/~asl-datasets/ijrr_euroc_mav_dataset/calibration_datasets/cam_april/april_6x6.yaml
• Camera-IMU calibration: http://robotics.ethz.ch/~asl-datasets/ijrr_euroc_mav_dataset/calibration_datasets/imu_april/imu_april.bag

Calibration targets

• Aprilgrid 6x6 0.8x0.8 m (A0 page) - target pdf april_6x6_80x80cm_A0.pdf and config yaml april_6x6_80x80cm.yaml
• Generate it yourself with kalibr_create_target_pdf --type apriltag --nx 6 --ny 6 --tsize 0.08 --tspace 0.3
• If you have the other please post below...

IMU configurations

• ADIS 16448 - config yaml imu_adis16448.yaml

It seems to be a common issue:

• Camera calibration  #510
• IMU yaml file #512
• CDE package not longer public #506
• Downloads are not open source #495
• Google drive link not working (09/23/2021) #467
• dataset #474
• drive links don't work #476
• Most file links in documentation no longer public #472
• can not download the Calibration targets #478
• could not download aprilgrid #509
