The image format of blk360

[Anonymous]

Hi,

I have imported the scan of blk 360 into recap pro and want to export the image file for my research work.

There is a `sourcedata` folder in the project directory and the folder contains a json file for and several raw image files.

Here is what I get now:

- I am able to import the raw file into the photoshop.

- In the raw file, I have some 4x4 calibration matrix (but I don't quite know the meaning)

I would like to ask, what is the mearning of the calibration matrix, e.g. what is the math of a point in 3D and the pixel in the specific image. I have attached the information for one image as below.
