Most computer vision research focuses on narrow angle lenses and is not adapted to super-wide-angle (aka spherical) lenses.
Enhancing learning-based computer vision algorithms accuracy in sUAS using navigation wide-angle cameras
The new generation of sUAS (small Unmanned Aircraft Systems) aims to extend the range of scenarios in which sense-and-avoid functionality and autonomous operation can be used.
Allowing natural scenes as well as maximizing field of view (FoV) can benefit from the minimization of distortion for the wide-angle camera.
Freeform technology is one of the most promising solutions to enhance the performance of optical systems.
We developed a Convolutional Neural Network to estimate depth on wide-angle images using panomorph lens with controlled distortion. We simulated three different lens model and compared their performances based on their zone of augmented resolution.
The phase shift imparted by a dielectric nanofin metasurface can be modelled following a semi-analytical assessment of the guiding properties. The model can be seen as a correction to the typically used Pancharatnam-Berry model.
Consumers nowadays have a higher expectation on cameras beyond the function of taking photos or videos.
Geometrical-based quasi-aspheric surface description and design method for miniature, low-distortion, wide-angle camera lens
In addition to utilizing traditional aspheric surfaces, complicated geometric curves for meeting stringent design requirements can also be adopted in optical systems.
