Enhanced 3D imaging accuracy using curved sensors: a simulation-based approach
Flat image sensors in 3D scanners suffer from edge blurring due to misalignment with the curved focal surface of lenses, leading to reduced image quality and measurement errors, and forcing complex, costly lens designs. This study proposes and simulates the use of curved sensors that align with the lens's focal surface, aiming to eliminate field curvature, improve image quality, and enhance measurement accuracy without complex lens systems.

Conventional flat sensors struggle with inherent optical aberrations like field curvature, which blurs image edges and compromises dimensional accuracy. Curved sensors directly address this by conforming to the natural focal surface of lenses, ensuring uniform sharpness across the entire field of view and simplifying lens design. This approach improves edge detection and overall measurement precision.
The study utilized software-based modeling (Code V, Metrovisionlab, MATLAB) to simulate and compare flat and curved sensor systems. A novel calibration approach for curved sensors was developed, transforming curved coordinates onto an equivalent flat plane for conventional calibration. Key optical errors (astigmatism, distortion, spherical aberration, coma) and measurement accuracy were quantitatively analyzed.
Curved sensors reduced measurement errors by 44.68% compared to flat sensors. Maximum astigmatism deviation was halved (0.04mm to 0.02mm), distortion reduced significantly (3% to 0.5%), and spherical aberration improved by approximately four times. These improvements lead to enhanced image quality, sharper edges, and more accurate dimensional measurements.
