• In meshroom, right click on empty space in node area, > Utils > CameraCalibration.
• keep node separate from rest of nodes
• go to actual file, and make sure if its a video, its in mp4. If its a picture/pictures, its in png
• move the file to the shortest file path you can. In my successful case, I moved the folder directly to the desktop and changed name of folder to 't'. i.e. C:\Users\ ____\Desktop\t
• copy/write file path into the CameraCalibration node's 'input' text field under attributes
• make sure to change 'size of pattern' and 'size of the square in mm'in the attributes. size of pattern = number of internal corners of x axis and then of y axis (if theres 8 blk and white squares, theres 7 internal corners). size of square in mm = actual printed size of each single square.
• run this singular node, the output file path will be at the bottom of attributes
