Combining the two images below we can extract the 3D location (x,y,z) of any edge-point with sub-pixel accuracy in 3D.
Measuring the 3D pose of the stop-cock
The zoomed images shows the accuracy we get with Scorpion Vision Software 9. The following is measured:
- The 3D-position (x,y,z) of two edge points z1 and z2
- The 3D-pose – (x,y,z,rx,ry,rz) and the radius of two circles
- z = -0.08 mm – r = 2.11 mm
- z= 5.26 mm – r = 4.67 mm
Note that that circles fit perfectly in a low contrast image due to the accurate 3D pose estimation. We let the visualisation speak for itself.
Everything work with low contrast and is sub-pixel in 3D!
The technology is available for use in Scorpion Robot Inspection, Scorpion Mono Stinger and Scorpion 3D Stinger applications.
