我的相机校准和失真矩阵,从aruco_calibration_fromimages.exe获得:

 [[3.19439125e+03   0.00000000e+00   1.98509417e+03]  
  [0.00000000e+00   3.20213561e+03   1.55099552e+03]  
  [0.00000000e+00   0.00000000e+00   1.00000000e+00]]

 [[0.1395281  -0.38313647  0.00505558  0.00237535  0.33952515]]

图片,我试图检测:

aruco_simple.exe成功

但是python代码找不到任何东西:

fs = cv2.FileStorage("./calib_asus_chess/cam_calib_asus.yml", cv2.FILE_STORAGE_READ)
cam_mat=fs.getNode("camera_matrix").mat()
dist_mat=fs.getNode("distortion_coefficients").mat()
gray=cv2.imread('C:\\Users\\steve\\Dropbox\\Projects\\kinnekt\\laser\\aruco_frames\\shot1.jpg',0)
adict = cv2.aruco.Dictionary_get(cv2.aruco.DICT_ARUCO_ORIGINAL)
res = cv2.aruco.detectMarkers(gray,dictionary=adict,cameraMatrix=cam_mat,distCoeff=dist_mat)

由于某种原因,res [0]是空数组.为什么python版本失败？感谢名单!
