Question

我正在尝试将OpenCV阈值与OpenCV VideoCapture模块检索到的depthImage一起使用，但是我收到以下错误：

OpenCV错误：未知函数中的错误参数，文件PATHTOOPENCV \ opencv \ modules \ core \ src \ matrix.cpp第646行

我的代码如下：

#include "opencv2/opencv.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/gpu/gpu.hpp"

cv::VideoCapture kinect;
cv::Mat rgbMap;
cv::Mat dispMap;
bool newFrame;

void setup()
{
    kinect.open(CV_CAP_OPENNI);
    newFrame = false;
}

void update()
{
    if(kinect.grab())
    {
        kinect.retrieve( rgbMap, CV_CAP_OPENNI_BGR_IMAGE);
        kinect.retrieve( dispMap, CV_CAP_OPENNI_DISPARITY_MAP );
        newFrame = true;
    }
}

void draw()
{
    if(newFrame)
    {
        cv::Mat * _thresSrc = new cv::Mat(dispMap);
        cv::Mat * _thresDst = new cv::Mat(dispMap);

        cvThreshold(_thresSrc, _thresDst, 24, 255, CV_THRESH_BINARY);

        // Draw _thresDst;

        delete _thresSrc;
        delete _thresDst;
        newFrame = false;
    }
}

非常感谢您的帮助

首先，您正在将C接口与C ++接口混合，它们不应混合在一起！

cv::Mat属于C ++界面，cvThreshold()属于C.您应该使用cv::threshold()代替：

double cv::threshold(const Mat& src, Mat& dst, double thresh, double maxVal, int thresholdType)

参数：

src – Source array (single-channel, 8-bit of 32-bit floating point)
dst – Destination array; will have the same size and the same type as src
thresh – Threshold value
maxVal – Maximum value to use with THRESH_BINARY and THRESH_BINARY_INV thresholding types
thresholdType – Thresholding type (see the discussion)
