Detailed description

I tried to run this code, and I set all input parameter type as float32, but it still have following report

Traceback (most recent call last):
  File "C:\Users\uqbduan\Desktop\OpenCV-Testing\main.py", line 40, in <module>
    imagePoints, _ = cv2.projectPoints(objectPoints, rvec, tvec, cameraMatrix, distCoeffs)
cv2.error: OpenCV(4.9.0) D:\a\opencv-python\opencv-python\opencv\modules\calib3d\src\calibration.cpp:270: error: (-205:Formats of input arguments do not match) All the matrices must have the same data type in function 'cvRodrigues2'

Steps to reproduce

import cv2
import numpy as np

objectPoints = np.array([[181.24588 ,  87.80361 ,  11.421074],
       [ 87.17948 , 184.75563 ,  37.223446],
       [ 22.558456,  45.495266, 246.05797 ]], dtype=np.float32)
rvec = np.array([[ 0.9357548 , -0.28316498,  0.21019171],
       [ 0.30293274,  0.9505806 , -0.06803132],
       [-0.18054008,  0.12733458,  0.9752903 ]], dtype=np.float32)

tvec = np.array([[ 69.32692 ,  17.602057, 135.77672 ],
       [ 33.281876, 180.08907 , 129.4395  ],
       [240.9262  ,  49.95762 ,  61.70667 ]], dtype=np.float32)

cameraMatrix = np.array([[214.0047  ,  26.98735 , 253.37799 ],
       [189.8172  ,  10.038101,  18.862494],
       [114.07123 , 200.87277 , 194.56332 ]], dtype=np.float32)

distCoeffs = distCoeffs = np.zeros((3, 1), dtype=np.float32)

imagePoints, _ = cv2.projectPoints(objectPoints, rvec, tvec, cameraMatrix, distCoeffs)


print(homogeneous_points)

Issue submission checklist

  • I report the issue, it's not a question
  • I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
  • I updated to the latest OpenCV version and the issue is still there
  • There is reproducer code and related data files (videos, images, onnx, etc)
