错误C4703潜在初始化本地指针变量'pBelowMask','pMask'和'pAboveMask'使用
我很想在Visual Studio 2017中安装cv blob lib,我在youtube上看到了教程。在尝试程序示例时,我得到:
答案 0 :(得分:0)
指针在从第156行开始的if语句中有条件地初始化:
if( maskImage )
{
pMask = (unsigned char*) maskImage->imageData + j * maskImage->widthStep;
// don't verify if we area on first or last row, it will verified on pointer access
pAboveMask = (unsigned char*) maskImage->imageData + (j-1) * maskImage->widthStep;
pBelowMask = (unsigned char*) maskImage->imageData + (j+1) * maskImage->widthStep;
}
那么当没有输入if语句时会发生什么,但指针仍在代码中使用?噗?崩溃?
