Hello,DIce helped a lot in my previous work. But I'm sorry to bother you again. I have some new problems now. Can you tell me the relationship between the parameters in the calibration file generated by dice and the calibration matrix in the following form? Or how to input the set calibration parameters?

The calibration tool in DICe wraps the OpenCV calibration tool. More information about the parameters above can be found here: https://docs.opencv.org/4.x/d9/d0c/group__calib3d.html. You will likely need to study the link above to make the connection to the transformation formula you provided above. Some elements will be simple, for example R and t in your formula are the rotation_3x3_matrix and TX, TY, TZ in the DICe cal file. K1, K2, and K3 are the distortion parameters (which are not represented in your formula) and the focal lengths FX and FY are related to f/dx and f/dy in your formula. u_0 and v_0 in your formula are likely CX and CY from DICe.

Thank you for your reply! I have solved the problem well!
