A Foveated Wide Angle Lens for Active Vision

چکیده
In this paper, we present a novel design and implementation of a foveated wide angle lens. It is strongly motivated towards applications for active vision in complex and dynamic environments. The projection curve is designed so that it facilitates active vision algorithms for motion analysis, object identi cation, and precise xation. The implementation achieves small size and light weight so that the lens can be swung at a high speed.

متن کاملCalibration of a Foveated Wide-Angle Lens on an Active Vision Head
Inspired by the properties of the humam visual system, a new active vision system called ESCHeR (Etl Stereo Compact Head For Robot Vision) has been recently implemented with foveated wide-angle lenses. The lenses exhibit a wide eld of view along with a space-varying resolution for facilitating both detection and close observation. However, to handle such optical properties and achieve basic eye...
متن کاملSuperimposed multi-resolution imaging
We present a novel approach to foveated imaging based on dual-aperture optics that superimpose two images on a single sensor, thus attaining a pronounced foveal function with reduced optical complexity. Each image captures the scene at a different magnification and therefore the system simultaneously captures a wide field of view and a high acuity at a central region. This approach enables arbi...
متن کاملAn Experimental Foveated Vision System using Fish-Eye Lens and Integration of Retinal Images
This paper present an experimental foveated vision system which simulates eye movement and non-uniform sampling of human vision system. Fish-eye lens is utilized to simulate eye movement by taking a partial image around the xation point. This makes the development of the active vision system easy. The log-polar sampling is employed to simulate the non-uniform sampling of retina. Then the succes...
متن کاملRobust real-time tracking on an active vision head
Achieving the rst step of a framework for humanrobot interaction, we have designed a binocular tracking system which uses disparity and velocity information for the detection and pursuit of moving objects in cluttered environments without a-priori knowledge of the target shape or texture. The implemented system robustly tracks in real-time deformable objects such as human hands and faces, takin...
