cv.calibrateCamera about mexopencv HOT 3 CLOSED

It looks you are giving wrong input for the function. You cannot append
extra dimension to the objectPoints array and imagePoints array. Check the
help.

Hello,

I'm trying to use cv.calibrateCamera but I didn't make it. Matlab is
crashing and it doesn't highlight any errors in the formula of
cv.calibrateCamera.

I built objectPoints cell array like this:
object_points = cell(1, BOARD_W*BOARD_H, successful_boards);
where BOARD_W and BOARD_H are width and height of the chessboard;
"successful_boards" represents the number of good boards in which i want to
store objectpoints and corners.

I built image points cell array like this:
img_points_L = cell(1, BOARD_W_BOARD_H, successful_boards);
img_points_R = cell(1, BOARD_W_BOARD_H, successful_boards);

when I run calibrateCamera matlab crashes.

Any idea?

thanks

how the input cell arrays have to be formatted? I can't find anything about this in the help.

Can you give me an example?

thank you
