When developing new products for Kitline Design I found the need to scan the interior profile of different vans. However doing so on a low budget proved difficult. Both photogrammetry and Kinect 3D scanning failed to yield the desired results.
We only needed “2D” scans at various points in the van, as such a Lidar scanner was used as it could generate extremely precise distance measurements on a 2D plane.
Utilising trigonometry I was able to develop a process that converts the raw LiDAR point scans (Angle and Measurement at that angle) into coordinates that can generate points in DXF format for CAD modeling.
2D to 3D
By generating these scans at regular intervals along the van it is possible to build a precise 3D model of the vans interior shape.
