摄像机标定OpenCV的蟒蛇

我下面OpenCV的教程http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_calib3d/py_calibration/py_calibration.html 摄像机标定OpenCV的蟒蛇

而是用一个棋盘运行它，我接到了一个LAS文件我的三维点坐标。这里是我的代码：

import cv2 
import numpy as np 

obj_point = [(630931.35,4833642.85,157.67),(630948.03,4833662.76,73.94), (631156.3, 4833904.18, 43.89),(630873.71, 4833790, 44.85), (631381.3, 4834152.6, 79.41)] 
img_point = [(1346.82,843.206),(1293.03,808.146),(1041.92, 585.168), (1150.21, 894.724), (756.993,345.904) ] 

obj_point = np.array(obj_point,'float32') 
img_point = np.array(img_point,'float32') 

ret, mtx, dist, rvecs, tvecs = cv2.calibrateCamera(obj_point, img_point, (1125, 1725),None,None)

我得到了以下错误消息：初始内在基质必须在功能上cvCalibrateCamera2

THX中指定

对于非平面校正台提前！

您需要使用国旗CV_CALIB_USE_INTRINSIC_GUESS

嘿谢谢你的回答！你知道“ret”的价值是什么吗？它是否重新投影错误？ –

dam then there is我猜想我的3d点有些问题。我的ret = 357 .. –
