【问题描述】：

当我尝试在 C++ (OpenCV 3) 中使用 uEye 相机时，在 0x..... (GpuAcc_64.dll) 处抛出异常。知道如何解决这个问题吗？这发生在代码行“VideoCapture capture = VideoCapture(1);”

我的代码：

#include "opencv2/highgui.hpp"
#include "opencv2/opencv.hpp"
#include "opencv2/calib3d.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <iostream> 
#include <fstream>

using namespace cv;
using namespace std;

int main()
{
    // The number of boards you want to capture, the number of internal corners horizontally 
    // and the number of internal corners vertically (That's just how the algorithm works). 
    int numBoards;
    int numCornersHor;
    int numCornersVer;

    cout << "Enter number of corners along width: ";
    cin >> numCornersHor;

    cout << "Enter number of corners along height: ";
    cin >> numCornersVer;

    cout << "Enter number of boards: ";
    cin >> numBoards;

    // We also create some additional variables that we'll be using later on. 
    int numSquares = numCornersHor * numCornersVer;
    Size board_sz = Size(numCornersHor, numCornersVer);

    // We want live feed for our calibration! 
    VideoCapture capture = VideoCapture(1);

【解决方案1】：

如果您使用的是带有专用板载 GPU 的笔记本电脑，请尝试禁用其中一个，看看是否可行。

我不知道究竟是什么导致了这个问题，但这就是为我解决了这个问题的原因。（更具体地说，禁用我的板载 GPU 修复了它）
