I'm working with Open3D with data from different devices. One of them does not provide the point cloud as a file, so I am creating the file by myself with a little Python script.

However, I am confused by the supported formats:
The pts format contains lines of [x, y, z, i, r, g, b]. xyz and rgb are intuitive and explained, but what exactly is the i for? And in what format is it exp

My Archlinux doesn't seem to have "trash" (moves to trash?):

The example for "Remove Distortion" is quite beautiful. The reverse is to place an image into a specified area of an image, most likely distorted. I wonder if it can be done by specifying the four corners. If not, please add other points. I guess the underlying code already exist in BoofCV. Just an example to show us how to bring up the functionality.

Thanks very much.

Great app - my congrats!
But: How can I make blender to render the background image? - is there a simple trick? Or do I have to import the background image again? - If so, how do I find correct position and size, as I cannot get hold really of an image in blender, just of a camera.
I couldnt find useful info in blender tutorials as well, so I'd be very grateful for some hints.

1. Generate insightful plots describing camera calibration accuracy. Here's an example: plot the graph of reprojection error vs number of images used for calibration.

2. Compare multiple methods (AprilTags vs Checkerboard)

This repo should have a DEVELOP.md file with guidance on how to get started with development and how to do releases, incl. pre-releases.

Let's update the documentation to capture that the library can be installed as a module. We should include an explanation of the pip install -e . or python setup.py develop syntax to capture that many developers may want to install in place so they can continue to update and develop the library code.
