c++ - 黄色检测程序断言失败

Question

我使用 C++ 和 opencv 创建了一个程序来检测和跟踪黄色。这个程序在我的 windows 和 ubuntu 操作系统的 PC 上运行正常，但是这个程序不能在我的 debian arm miniPC 上运行。

我收到错误:opencv 错误:getMat 中断言失败 (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

我试图评论下面的代码，我发现其中一个问题出在函数 inRange() 上，但我不知道它出了什么问题，因为这个程序在我的 PC 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。即像素是否在范围内。您应该将 Lyellow 和 Ryellow 声明为 1 channel Mat 结构，例如 CV_8UC1。
