使用cv2.findContours时出错 [英] Error when using cv2.findContours

问题描述

我试图找到图像的轮廓，但是它给出了一个错误.

I tried to find contours for image, but it gives an error.

我的代码是:

import cv2
import numpy as np

img = cv2.imread('star.jpg',0)

ret,thresh = cv2.threshold(img,127,255,0)

contours,hierarchy = cv2.findContours(thresh, 1, 2)

错误是:

Traceback (most recent call last): File "C:\Python27\OpenCVContore.py", line 5, in <module> contours,hierarchy,thresh = cv2.findContours(thresh, 1, 2) error: ........\opencv\modules\core\src\matrix.cpp:236: error: (-215) step[dims-1] == (size_t)CV_ELEM_SIZE(flags) in function cv::Mat::create

我正在使用Python 2.7 OpenCV 2.4.7,2.4.11

感谢您的帮助.

推荐答案

通过将我的python版本更新为3.4和opencv版本3解决了此问题.但是找不到真正的解决方案.为什么python 2.x版本不完全支持openCV

Solved this problem by updating my python version to 3.4 and opencv version 3. But cannot find real solutions for this. Why python 2.x versions not fully support for openCV
