Overlapped compound eye

Abstract

The overlapped compound eye comprises m sub-eye micro lenses arranged on a sub-eye arrangement surface, and further comprises a projection module and a photoelectric detector, the projection module is fixed on the curved surface of the compound eye, and the projection module projects a preset coding pattern to a target object; and the sub-eye micro lens is connected with the photoelectric detector through the transmission module. According to the method, a curved image detector which is highly matched with a curved compound eye and is difficult to process and manufacture does not need to be manufactured, only one photoelectric detector without spatial resolution is used for recording light intensity information, imaging is calculated through a single-pixel technology, and the design and manufacturing cost of a high-precision optical part is greatly saved; the imaging resolution of the compound eye is not limited by hardware such as the number of the sub-eyes and the clear aperture size of the sub-eyes any more, the imaging resolution is improved by two orders of magnitude, and the super-resolution imaging capacity is achieved; according to the method, the complete recognizable image of the target can still be obtained under the condition that part of the sub-eyes are damaged or shielded and cannot work normally, and the robustness is greatly improved.

Description

technical field [0001] The invention relates to the technical field of compound eyes, in particular to an overlapping compound eye. Background technique [0002] Traditional bionic compound eyes usually use a planar image sensor (CCD or CMOS) as the optical perception element, but the planar photodetector array is not only far from the photoreceptors of the actual compound eye, but also different from most curved bionic compound eyes. It is difficult to cooperate, which makes the acquired image affected by aberrations, etc., and the resolution and imaging clarity cannot meet the actual needs. At the same time, in the normal working process of the compound eye, it is inevitable that the channel is damaged, and the small eye is blocked by other substances (such as water, smoke) and cannot work normally. The robustness of the traditional bionic compound eye based on the image sensor is usually not high. [0003] Generally speaking, most of the currently designed bionic compoun...

[0002] Traditional bionic compound eyes usually use a planar image sensor (CCD or CMOS) as the optical perception element, but the planar photodetector array is not only far from the photoreceptors of the actual compound eye, but also different from most curved bionic compound eyes. It is difficult to cooperate, which makes the acquired image affected by aberration, etc., and the resolution and imaging clarity cannot meet the actual needs

At the same time, in the normal working process of the compound eye, it is inevitable that the channel is damaged, and the small eye is blocked by other substances (such as water, smoke) and cannot work normally. The robustness of the traditional bionic compound eye based on the image sensor is usually not high.

[0003] Generally speaking, most of the currently designed bionic compound eyes rely on flat focal plane detectors as photoelectric sensing elements, which is difficult to cooperate with curved bionic compound eyes.

Image quality is affected by optical components, and aberrations are prone to problems during imaging; the imaging resolution of existing bionic compound eyes is limited by the number of sub-eyes and the size of the sub-eye clear aperture, and increasing the imaging resolution will increase the number of sub-eye lenses. The production cost; the existing bionic compound eyes have not made a special design for whether some of the sub-eyes can continue to work normally. Once some sub-eyes fail to work, the imaging will be missing.
