u = pts2d[:,0]
v = pts2d[:,1]
X = pts3d[:,0]
Y = pts3d[:,1]
Z = pts3d[:,2]
A = np.zeros(40,12)
for i in range(1,2,40):
 for j in range ((i + 1) / 2): 
     A[i:i+1, :] = np.concatenate(X[j], Y[j], Z[j]  1, 0, 0, 0, 0 - u[j]*X[j]-u[j]*Y[j]-u[j]*Z[j]-u[j] 0, 0, 0, 0 X[j], Y[j], Z[j], 1 - v[j]*X[j]-v[j]*Y[j]-v[j]*Z[j]-v[j])

v[j]*X[j] 出错。为什么我不能将它们相乘？

Answer 1

您忘记了某些术语之间的逗号，例如：0 X[j] 这可能是您的语法错误的来源。您还需要将所有这些术语放在一个列表中以便串联工作。

这是 copy/pasting;

的整行

A[i:i+1, :] = np.concatenate([ X[j], Y[j], Z[j], 1, 0, 0, 0, 0 - u[j]*X[j]-u[j]*Y[j]-u[j]*Z[j]-u[j], 0, 0, 0, 0, X[j], Y[j], Z[j], 1 - v[j]*X[j]-v[j]*Y[j]-v[j]*Z[j]-v[j] ])
