Why are there 6400 rectangles in the pom file

[scut-salmon]

I found that there are 6400 rectangles for each cam in the file rectangles80x80.pom.

and I have read the code to produce .pom file from：
https://github.com/pierrebaque/generatePOMfile

If I want to get the pom file, do I need to place a previous chessboard in ground plane to obtain the camera calibration files (OpenCV format)

Thanks for your time

Hello,

You need to calibrate your cameras in some way, using either a chessboard on the ground, or other markers.
You need the intrinsic and extrinsic calibration values.

Best,
Pierre
