Try to pick more correspondences by placing the checkerboard in various orientations, distances, and different perspectives of the checkerboard plane and cover as much of the LiDARs field of view...

I think you might need to reshape your points array (guessing you need to merge the first two axes?), Follow the modifications for Ouster LiDAR in the code. See #26.

You should update the point cloud field-of-view to display in this line https://github.com/heethesh/lidar_camera_calibration/blob/master/scripts/calibrate_camera_lidar.py#L232 as mentioned in the README. Matplotlib GUI does not handle a large point cloud very well and...

Regarding the matplotlib error, try upgrading it to >2.0 `pip install -U matplotlib`

You should record several poses of the board when it is visible both in the camera and LiDAR view. The picked point are stored and will auto-update every time you...

Yes, they should be in meters

I am not exactly sure which matrix you are referring to, I believe you just want a blank image with all the LiDAR points projected to the image space for...

> So, if I wanted to store and save the data from the `points2D` and `points3D`, I can just use `cv2.imwrite` or the numpy `np.save` to a variable or file?...

See [this](https://github.com/heethesh/lidar_camera_calibration#run-camera-calibration) in README https://github.com/heethesh/lidar_camera_calibration/blob/master/scripts/calibrate_camera_lidar.py#L436

Can you refer to issue #16 to debug if the topic names are correct and the callback function gets called? No, you don't need an internet connection, but I would...
