undistort the endpoints of keylines

[MikCSL]

I found that you don't undistort the endpoints of keylines. Is it not necessary to undistort the endpoints of keylines?

Hi,

for that I followed some of the PL-VINS's implementation, I first undistort the image and then extract the keylines. Hence, the saved keylines should be undistorted.

code see: Structure-PLP-SLAM/src/PLPSLAM/feature/line_extractor.cc function: void LineFeatureTracker::extract_LSD_LBD()

Best,
