Accurate 3D Mapping Algorithm for Flexible Antennas

Figure 15

An example of a surface movement observed by 30 (5 × 6) targets (see Figure 16). Comparing two images, with an average tilt change of about 1 mm. A change of 0.1 pixel at targets is detectable (strongly above the noise level), allowing a z-accuracy of about 0.2 mm on level₁.
