我试图从我遵循此处描述的输入类型中找到校准,但我遇到了这个错误:

error: OpenCV(4.4.0) /tmp/pip-req-build-6amqbhlx/opencv/modules/calib3d/src/solvepnp.cpp:753: error: (-215:Assertion failed) ( (npoints >= 4) || (npoints == 3 && flags == SOLVEPNP_ITERATIVE && useExtrinsicGuess) ) && npoints == std::max(ipoints.checkVector(2, CV_32F), ipoints.checkVector(2, CV_64F)) in function 'solvePnPGeneric'

示例代码

这个错误可能来自哪里的任何提示?
