I have already obtained the instrinsic parameters of the camera and I know the point's location (x,y). However, I want get reprojection error on a image. How can I get the location when some point is reprojected?

I tried to use the 'reconsturct' function, but I am not sure if this function will work the I want.

My OpenCV version is 4.3

Thanks.

The problem was simpler than I thought.

When the coordinates of the points found in the image are called ( a,b ),

The difference between (a2, bx ) obtained by re-projecting the parameter obtained through caliberation ( a,b,1 ) by multiplying the coordinates by (a,b, 1).
