这是运行高翔slambook2的代码出现的错误

terminate called after throwing an instance of ‘cv::Exception’
what(): OpenCV(3.4.15) /home/diyu/opencv-3.4.15/modules/imgproc/src/resize.cpp:4051: error: (-215:Assertion failed) !ssize.empty() in function ‘resize’

问题原因就在于代码中的文件路径找不到，所以出现为空的问题。

比如我这里以slamboo5/ch8 中的代码示例

如图，代码中文件路径使用相对路径，这里即图片与代码在一个文件夹下

但是我们编译这种cmake文件时习惯新建build文件，这样我们生成的目标文件（可运行文件）就在build文件夹下了。

所以，有两种方法

要么选择修改代码中的文件路径。这里的话就是将 ./ 修改成 ../
要么将build文件下生成的可运行文件（目标文件）移到上级目录

这里展示第2种

这里是在新建build文件夹下编译的，编译生成了两个目标文件

然后，将build中生成的目标文件移到上级目录

然后在上级目录中打开终端运行即可。
