How to format object points for cv2.calibrateCamera()? OpenCV

I am trying to pass custom object points and image points into cv2.calibrateCamera(). By custom points I mean points I have calculated without finding chessboard patterns. I'm trying to only warp the image horizontally (x direction) and I'm using the image points as a "map from" and object points as a "map to".

My object points look like this:

[[[ 254.1        0.         0.     ]]
 [[ 268.40825    0.         0.     ]]
 [[ 282.7165     0.         0.     ]]
 ...
 [[1541.8425  1080.         0.     ]]
 [[1556.15075 1080.         0.     ]]
 [[1570.459   1080.         0.     ]]]

code:

object_points = np.empty((0, 1, 3))

for p in range(0, 1081, 5):

    for q in range(0, 93):

        t = 0.1075 * q

        object_points = np.append(object_points, [[[get_undistorted_value(t), float(p), 0.0]]], axis=0)

But I get an error when passing them to calibrateCamera().

objectPoints should contain vector of vectors of points of type Point3f in function 'cv::collectCalibrationData'

Isn't this meant for c++? How do I format the image points and object points for python?

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
