<>项目场景:
再跑SLAM14讲里面的例程的时候发现的问题
例如:在ch8中,执行光流法optical_flow :
vision@ubuntu:~/slambook/slambook2/ch8/build$ ./optical_flow
<>问题描述
出现以下问题:
terminate called after throwing an instance of 'cv::Exception' what():
OpenCV(4.5.3)
/home/vision/slambook/opencv-4.5.3/modules/imgproc/src/resize.cpp:4051: error:
(-215:Assertion failed) !ssize.empty() in function 'resize'
<>原因分析:
我们一般都是在build文件夹下进行编译的。导致加载图片的路径出现错误。
主要是cpp文件中图片的路径没有识别到。
string file_1 = "./LK1.png"; // first image
string file_2 = "./LK2.png"; // second image
<>解决方案:
在cpp源文件中修改加载图片的路径(使用绝对路径亦可以),或将图片拷贝带build文件夹下。
