我正在尝试使用（opencv 2.4.2）函数中的cv2.estimateAffine3D()来估计3D点集之间的仿射3D变换。
这是我的代码：
def computeAffine3d():
# Init src and dst points to 0
src_points = cv2.cv.CreateMat(1, 4, cv2.cv.CV_32FC3)
dst_points = cv2.cv.CreateMat(1, 4, cv2.cv.CV_32FC3)
cv2.cv.Zero(src_points)
cv2.cv.Zero(dst_points)
# Convert cv Mat to numpy array
src_points = np.array( src_points )
dst_points = np.array( dst_points )
# Set src_points to (0,0,0), (1,0,0), (0,1,0) and (0,0,1)
# Set dst_points to (1,0,0), (2,0,0), (1,1,0) and (1,0,1)
src_points[0][1][0] = 1.0
src_points[0][2][1] = 1.0
src_points[0][3][2] = 1.0
dst_points[0][0][0] = 1.0
dst_points[0][1][0] = 2.0
dst_points[0][2][0] = 1.0
dst_points[0][2][1] = 1.0
dst_points[0][3][0] = 1.0
dst_points[0][3][2] = 1.0
# Compute Affine 3D tranformation
ok_flag, H, status1 = cv2.estimateAffine3D(src_points, dst_points)
print ok_flag, ', ', H, ', ', status1
执行这段代码后，我得到以下错误：
cOpenCV Error: Assertion failed (CV_ARE_SIZES_EQ(m1, m2) && CV_ARE_SIZES_EQ(m1, mask)) in runRANSAC, file /tmp/buildd/ros-fuerte-opencv2-2.4.2-0precise-20120908-1632/modules/calib3d/src/modelest.cpp, line 122

有什么想法吗？ 亲爱的！
