Reconstruction error estimation of the vision-based reconstruction with the point-circle invariant and the laser plane that is coplanar to the 2D reference. (a–d) the camera-reference distance is 600 mm, the scaleplate-projector distances are 100–400 mm with the 100 mm interval. (e–h) the camera-reference distance is 700 mm, the scaleplate-projector distances are the same as (a–d). (i–l) the camera-reference distance is 800 mm, the scaleplate-projector distances are the same as (a–d). (m–p) the camera-reference distance is 900 mm, the scaleplate-projector distances are the same as (a–d).
