使用opencv-python進行跟蹤項目。當調用estiamte單個標記..任何想法時,我得到這個錯誤?ValueError:解壓縮的值太多opencv-python
CV2版本3.2.0-dev的
蟒版本2.7.12
Traceback (most recent call last):
File "test_aruco_detect.py", line 53, in <module>
rvecs , tvecs = aruco.estimatePoseSingleMarkers(corners, 0.1765, cameraMatrix, distCoeffs)
ValueError: too many values to unpack
的代碼:
import numpy as np
import cv2
import cv2.aruco as aruco
with np.load('/home/odroid/camera_calibration/testfile.npz') as X:
cameraMatrix,distCoeffs = [X[i] for i in ('arr_0','arr_1')]
cap = cv2.VideoCapture(0)
while(True):
# Capture frame-by-frame
ret, frame = cap.read()
#print(frame.shape) #480x640
# Our operations on the frame come here
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
aruco_dict = aruco.Dictionary_get(aruco.DICT_6X6_250)
parameters = aruco.DetectorParameters_create()
#lists of ids and the corners beloning to each id
corners, ids, rejectedImgPoints = aruco.detectMarkers(gray, aruco_dict, parameters=parameters)
if ids != None: #if atleast one id is detected
gray = aruco.drawDetectedMarkers(gray, corners,ids)
rvecs , tvecs = aruco.estimatePoseSingleMarkers(corners, 0.1765, cameraMatrix, distCoeffs)
aruco.drawAxis(gray, cameraMatrix, distCoeffs, rvecs, tvecs)
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
雖然此代碼可能回答問題,但提供有關如何解決問題以及爲何解決問題的其他上下文將提高答案的長期價值。 – cpburnz
