将OpenCV阈值与Kinect图像一起使用

我正在尝试使用OpenCV Threshold和OpenCV VideoCapture模块检索的depthImage，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， 你将C接口与C ++接口混合在一起，它们不应混合在一起！

cv::Mat属于C ++接口，而cvThreshold()属于C.你应该使用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)
