所有, 我有一個使用了OpenCV來校準相機python腳本。它現在可以從stackoverflow幫助中得到很多幫助。但是,我遇到了畸變常數問題。我似乎無法控制適合的常量數量。我想只有4 distoriton常量,而不是5.在它規定的文檔「也就是說,如果向量包含四個要素,這意味着K3 = 0」,這是我想要的。於是,我開始dist_const = np.zeros(4),它傳遞給cv2.calibrateCamera,但返回dist_const已經回到5個常量。我也試着旗CV_CALIB_FIX_K3,但要得到一個「的iteger必須asigned」的錯誤。有沒有人見過這種行爲之前,任何幫助將不勝感激。OpenCV的攝像機標定,無法控制畸變常數

dist_coefs = np.zeros(4,'float32')
retval,camera_matrix,dist_coefs,rvecs,tvecs = cv2.calibrateCamera([obj_points],[img_points],size,camera_matrix,dist_coefs,flags=cv.CV_CALIB_USE_INTRINSIC_GUESS)
print camera_matrix
print dist_coefs
鏈接到我的其他問題,有dist_coefs結果,來自加州理工學院的MATLAB代碼我想使用Python/OpenCV的更換。
