运行开始出现段错误

[xyflzyn]

使用的是和ORB-SLAM2一样的指令，运行开始就报错了，请求大佬指点

[xyflzyn]

运行指令 ./Examples/Monocular/mono_euroc ./Vocabulary/ORBvoc.bin ./Examples/Monocular/EuRoC.yaml /home/slam/dataset/V1_01_easy/mav0/cam0/data /home/slam/dataset/V1_01_easy/V101.txt

Tracking.cc文件内读取的是./mask/mask.png图片，大小为640x480，EuRoC数据集图片大小是752x480的，所以报这个错误。 解决办法：自己制作一个752x480的euroc_mask.png，然后将Tracking.cc文件读取mask的路径改下，就可以正常运行。
