System information (version)
- OpenCV => 4.6.0
- Operating System / Platform => Ubuntu 20.04
- Compiler => Python
Detailed description
With the version 4.6.0, the function interpolateCornersCharuco misplace some corners. In my case, the corners that are misplaced are the right most ones that are placed at the center of the board.
The previous steps of the detection with the drawDetectedMarkers is working correctly.
I have tested with the version 4.5.5 and it works in this version.
Steps to reproduce
import copy
import matplotlib.pyplot as plt
import cv2
if __name__ == "__main__":
dictionary = cv2.aruco.getPredefinedDictionary(7)
charucoboard = cv2.aruco.CharucoBoard_create(29, 18, 0.01, 0.007, dictionary)
detectorsparam = cv2.aruco.DetectorParameters_create()
img = cv2.imread("image.png")
arucocorners, arucoids, rejected = cv2.aruco.detectMarkers(img, charucoboard.dictionary)
if len(arucocorners) > 0:
imgmarkers = copy.deepcopy(img)
cv2.aruco.drawDetectedMarkers(imgmarkers, arucocorners, arucoids)
plt.imshow(imgmarkers)
plt.show()
retvalue, charucocorners, charucoids = cv2.aruco.interpolateCornersCharuco(arucocorners, arucoids,
img, charucoboard)
if len(charucocorners) > 0:
imgcorners = copy.deepcopy(img)
cv2.aruco.drawDetectedCornersCharuco(imgcorners, charucocorners, charucoids)
plt.imshow(imgcorners)
plt.show()Here is the image used to do the test.
