我试图让OpenCV 2.4.5从我的网络摄像头识别棋盘图案.我无法做到这一点,所以我决定尝试使用"完美"的图像让它工作:

但它仍然不起作用 - patternFound每次都返回false.有谁知道我做错了什么？

#include <stdio.h>

#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/calib3d/calib3d.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv;
using namespace std;

int main(){
    Size patternsize(8,8); //number of centers
    Mat frame = imread("perfect.png"); //source image
    vector<Point2f> centers; //this will be filled by the detected centers

    bool patternfound = findChessboardCorners(frame,patternsize,centers);

    cout<<patternfound<<endl;
    drawChessboardCorners(frame, patternsize, Mat(centers), patternfound);

    cvNamedWindow("window");
    while(1){
        imshow("window",frame);
        cvWaitKey(33);
    }
}

我已经安装了 Google Cloud SDK 并希望我正在编写的代码通过 pylint。不幸的是，每当我从 google.* 导入任何东西时，我都会收到一个错误：

E: 10, 0: No name 'cloud' in module 'path/to/my/current/module.google' (no-name-in-module)
E: 10, 0: Unable to import 'google.cloud' (import-error)

版本：

$: pylint --version
pylint 1.7.0,

如果我在 pylint 中放置一个钩子来打印出 sys 路径，我将没有任何有趣的东西。google-cloud-sdk 在，/usr/local/lib/python2.7/dist-packages所以它应该能够找到它。

有谁知道为什么它会在我的本地路径中查找“google”模块以及如何修复它？
