solvepnp 中出现错误； OpenCV 断言错误

Question

这是为了姿态估计

执行校准后，输出图像点和对象点将作为 solvePnP 函数的输入给出：

ret,revc,tvec= cv.solvePnP(temp1,temp2, cameraMatrix, dist)

出现的错误是：

error: (-215:Assertion failed) ( (npoints >= 4) || (npoints == 3 && flags == SOLVEPNP_ITERATIVE && useExtrinsicGuess) || (npoints >= 3 && flags == SOLVEPNP_SQPNP) ) && npoints == std::max(ipoints.checkVector(2, CV_32F), ipoints.checkVector(2, CV_64F)) in function 'cv::solvePnPGeneric'

添加代码片段：

objpoints = np.ascontiguousarray(objpoints)

imgpoints = np.ascontiguousarray(imgpoints)

temp1 = np.stack(objpoints,axis=0)

temp2 = np.stack(imgpoints,axis=0)

ret,revc,tvec= cv.solvePnP(temp1,temp2, cameraMatrix, dist)

有人可以帮忙解决这个问题吗？ ？
