We analyze the measuring principle and propose a calibration technique based on perpendicular cross-lines for line structured light 3D scanner. By use of straight line features and perpendicular ...

Using dense 3D point cloud also requires high memory capacity for visualization. In this work, we propose to reconstruct 3D surface using sparse 3D point cloud generated by SfM and 3D line segments ...

Two years after Gov. Wes Moore revived the Red Line, Baltimore’s proposed east-west light rail feels mired in uncertainty.

And thankfully, those upgrades are on the way: After being closed or partially closed for renovations for a troublesome four years, four shiny new Red Line stations are set to open on Sunday, July 20.
