Question

我使用c ++和opencv创建了一个检测和跟踪黄色的程序。这个程序通常在我的电脑上运行Windows和ubuntu操作系统，但是这个程序无法在我的debian arm miniPC中运行。

我收到错误： opencv错误：getMat中的断言失败（k == STD_VECTOR_MAT）。文件/build/buildd-opencv_2.3.1-11-armhf-d9JIli/opencv-2.3.1/modules/ core / src / matrix.cpp，第918行

我试着评论下面的代码，我发现其中一个问题是函数inRange（），但我不知道它有什么问题，因为这个程序可以在我的电脑上运行。

我正在使用qtcreator 2.5.0 qt 4.8.2和opencv 2.3.1-11

Answer 1

inRange（）返回灰度输出。即，是否在范围内的像素。你应该将Lyellow和Ryellow声明为1通道Mat结构，如CV_8UC1。
