about mono camera pose result evaluate

[Chrislzy1993]

hi, @plusk01 @MichaelGrupp @ToniRV @slowlythinking @miseryofdevice i have a problem!
when i run orbslam in mono mode by kitti dataset, i get a keyframe result, i want to evaluate the result with groundtruth pose. cause mono mode lack of scale, when i use evo to draw the trajectory, i get the following pic:
and keyframe num is about 2000 , and camera frame is about 4000



i am confused, how to deal with scale problem, i am a Newbies
