Target-based lidar2camer - Size of check board pattern for calibration board #57

Open TheExplorer95 opened 1 year ago

Hey guys, in Figure 7 of your paper, you show the calibration board used for the target-based lidar2camera calibration method. I'm curious about the exact sizing of the checkboard patterns, as I couldn't find any references. Based on your drawing, it is 900mm x 390mm large with 18x8 squares. Correct me if I'm wrong, but this results in 50x48.75 mm sized squares, which seems odd.

The calibration board: image

Some guidance is highly appreciated :)

Sorry, you are right, there is an error in the picture we put in this paper, and we will make a correction later.

What are the correct dimensions? Is it that the circles have a diameter of 200mm?

Unfortunately, I have no clue so far and am still waiting for the correct values. I've changed to ATOM for now, which works fine, but does not provide fully automatized labeling of the point cloud data.
