...These small segments are then eliminated during the validation step, and therefore, only a few detections are made (Grompone von Gioi et al., 2010)....

...Similar to Desolneux et al. (2000) and LSD (Grompone von Gioi et al., 2008b, 2010), our line validation method is based on the Helmholtz principle, which basically states that for a structure to be perceptually meaningful, the expectation of this structure (grouping or Gestalt) by chance must be…...

...…get errors of +1 and 1), and an angle tolerance of 22.5 (refer to Section 5.2), we compute the gradient threshold by the following formula given in Grompone von Gioi et al. (2010): q ¼ 2 sinð22:5Þ ¼ 5:22 Going over the gradient map and eliminating pixels with gradient values less than ‘‘q’’, we…...

...Following the discussion in Grompone von Gioi et al. (2010), we set ‘‘q’’ so as to leave out points where angle error is larger than the angle tolerance....

...Finally, by the time of the first submission of this paper, a work with the same name (PL-SLAM, [36]) was published extending the monocular algorithm ORB-SLAM to the case of including line segment features computed through the line segment detector (LSD) detector [37]....

...We obtain VPs by finding line segments with LSD [von Gioi et al. 2010], then clustering the segments with J-Linkage [Toldo and Fusiello 2008], and solving for the optimal VP for each cluster [Tardif 2009; Feng et al. 2010]....
