AI Technical Summary
Existing 3D sensing systems suffer from high costs, large system size, complex optical path calibration, and mismatch between field of view and speckle density when switching depth of field. Furthermore, they are prone to depth calculation failures on highly reflective objects.
A zoom polarized light projector is used, which combines a zoom collimating lens group with a single diffractive optical element. By utilizing a light source module with independent zone control, the field of view and speckle density of a single projector are consistent under different depths of field. Combined with an analyzer, frame-by-frame acquisition and image fusion processing are performed.
It achieves consistency of structured light patterns under different depths of field, improves the accuracy of depth calculation and system adaptability, simplifies system structure, reduces hardware cost and calibration complexity, and improves the accuracy of 3D perception in high-reflectivity environments.
